Title: Omoto KTB 300 underhead aka "what the heck is this" ..
Post by: steelfish on June 25, 2015, 06:38:08 PM
well, another local fishing charter guy contact me to fix some of their reels (mostly 500L, 113 and 113h) and saw a big box of broken reels and old greasy parts on a corner of the room and I saw this reel, asked the guy what it was doing this reel there he told me that was a box of parts that goes to the trash can. damn it, can I save it ? of course take it if you want it I dont even know where I got it, he told me.

Im pretty sure I have read about this reel on the web some where, I did a quick search yesterday and no luck I dont even know how to search for this model its not a casting reel, a baitcasting or a spincasting, its like a breed of spinnercasting or castspinner.
I dont know if it was a disaster as design or how bad or good perform on the fishing field but it will surely go to my collectibles reels and this will always start a nice conversation about it.

I only cleaned some oil and dust that was on some parts of the reel for the pictures, if you have any link or any comment about this reel please feel free to post it, this reel does no have any model number, name, etc other than omoto name, a nice logo stamp and the indications of "3 ball bearings"
the reel spins super freely and fast, on my all cleaned and serviced abu 6500c3 all I can do when a turn the handle fast is to run barely 2 runs of the levelwind one to left and then back to right at the starting point..on this reel the levelwind make 3 runs or even 4 runs, to left then to right then to left and one last time to right, awesome.

this is the way it was originally, no handle, I might drill the left material on the handle spot and install a nice handle knob for it later

body of the reel is 100% solid aluminum and side plates feel like thin aluminum over plastic side plates
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/P1050413%20ss_zpsqolub0vi.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/P1050413%20ss_zpsqolub0vi.jpg.html)

omoto original logo on the left side

the free spool lever acts like the ones on the baitcasting reels (calcutta ) you turn the lever to free spool and cast as soon as you move the handle the reel goes to brake mode.
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/P1050418%20ss_zps0fjufmgd.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/P1050418%20ss_zps0fjufmgd.jpg.html)


this handle belongs to a daiwa advantage freshwater baitcasting reel, not the best fit but it will work while working on the reel and try some casting later (wondering how to cast on this thing).

at least it was no made in china

I didnt continue with the teardown to see the guts because it was really late yesterday, hey, even my helper felt sleep before me this time
too bad I had to wake her up to take my tool box (pillow) and clean the mess before my wife wake up in the morning. ::)

stay tune for the autopsy ........of the reel not the cat



update, aug 2020, found the correct name of that type of reels, they are called "UnderHead reels"
Title: Re: Omoto cast-spinner reel aka Gem found aka what the heck is this
Post by: johndtuttle on June 25, 2015, 09:01:05 PM
This style of under the rod conventional reel is coming back. Accurate has got one in the works because the "fighting position" when bit heavy on  a private boat (low rail) is superior.

Kinda like and "acid wrapped" rod going one step further. It makes no logical sense for the reel to be on top of the rod for balance reasons when fighting a fish (assuming you have no practical rail to use) but for casting reasons it is more relegated to simple deep dropping.

Post by: steelfish on June 25, 2015, 10:25:02 PM
accurate has one on the works? thats sounds interesting, I would like to see the prototype

I agree with you on the casting issue, having the rod above the reel is going to make it hard to make long casts on this type of reels.
do you have an idea how this type of reels are named?  I cant believe there is zero info (or at least no easy to find) about this reels

Post by: fIsHsTiiCkS on June 25, 2015, 11:08:17 PM
I'm very interested to see the internals, nice post. I have started drifting toward spinners for certain things as it is much easier to get around ppl and cast on the crowded party  boats

You can also probably just add a knob to the old handle and should fit nice

this is the way it was originally, no handle (knob), I might drill the left material on the handle (knob hole) spot and install a nice handle knob for it later

you probably missed this part and my english didnt helped also,  I edited what I quoted and put in brackets what I should have said for be more clear.

if the internals looks promising then I will invest on a nice shiny aluminuim knob, if not they might just get some cheapos on ebay
the stock handle arm have no visual corrosion and have a nice counterbalance weight, it will worth a nice knob

ok, here are the inside guts of the Omoto reel, no schematics anywhere so, no parts number or key part name, no even techical name, look at the pictures and enjoy seeing the guts and details of this Unique reel.


took the reel foot from the frame, good thing to dont find corrosion there, just salt accumulated
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050503%20ss_zpsuuvmyljg.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050503%20ss_zpsuuvmyljg.jpg.html)


without the reel foot it looks like any regular baitcasting round levelwind reel
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050505%20ss_zps7mo7zluk.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050505%20ss_zps7mo7zluk.jpg.html)


just like a though, side plates are plastic (graphite?) and cover with thin stamped aluminuim
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050508%20ss_zps2lzcxanl.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050508%20ss_zps2lzcxanl.jpg.html)


this is open the left side plate out, nothing extraordinary here
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050509%20ss_zpsny5q1l5h.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050509%20ss_zpsny5q1l5h.jpg.html)

notthing bad either, the spool wall looks like new
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050517%20ss_zpskqynch8g.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050517%20ss_zpskqynch8g.jpg.html)


now lets go the the right side, star is metal, feels like Stainless Steel
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050518%20ss_zpseyrhteln.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050518%20ss_zpseyrhteln.jpg.html)


spacer after the star
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050520%20ss_zpsdehopd9o.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050520%20ss_zpsdehopd9o.jpg.html)


nice blue seal bearings
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050522%20ss_zpsxzb0bceg.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050522%20ss_zpsxzb0bceg.jpg.html)


opening the right side plate... a lot of  Stainless Steel over there
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050524%20ss_zpsootgtpfy.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050524%20ss_zpsootgtpfy.jpg.html)

the frame, a nice a solid block of aluminiun, not billet or 6061, but a lot better than plasting or graphite frame
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050526%20ss_zpswjyijo8z.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050526%20ss_zpswjyijo8z.jpg.html)


levelwind plastic cover, 100% silver painted plastic with a copper tube
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050528%20ss_zpsf6ign4rl.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050528%20ss_zpsf6ign4rl.jpg.html)

looks pretty sturdy here, all SS parts, main gear plate (sic), eccentric, yokes, spring
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050532%20ss_zpsqpa1rswd.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050532%20ss_zpsqpa1rswd.jpg.html)

right side plate has the same thin stamped aluminium cover over the graphite
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050534%20ss_zpscf5vd5gn.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050534%20ss_zpscf5vd5gn.jpg.html)



another great find,  dog is SS too and with a nice sturdy spring
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050541%20ss_zpsjeaa4zvd.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050541%20ss_zpsjeaa4zvd.jpg.html)


the drag stack, yep, main gear is SS too
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050544%20ss_zpsmz1movr0.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050544%20ss_zpsmz1movr0.jpg.html)

drag stack order
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050546%20ss_zpsdpt0g89a.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050546%20ss_zpsdpt0g89a.jpg.html)

it has all the SS goodies already
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050543%20ss_zps8s77luxi.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050543%20ss_zps8s77luxi.jpg.html)


drag washers, no sure which material is used here, but looks almost new, I will change them for Carbontex before closing the reel.
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050549%20ss_zpssxefgkck.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050549%20ss_zpssxefgkck.jpg.html)


opened the drive shaft bearing and the lube job its not that bad, anyway I clean it with carb cleaner, compressed air and marine yamaha grease
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050584%20ss_zpsspajy2xe.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050584%20ss_zpsspajy2xe.jpg.html)

really well packed with marine grease
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050586%20ss_zpsltzjjckf.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050586%20ss_zpsltzjjckf.jpg.html)

and put the blue seal back
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050588%20ss_zpszdjyl7no.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050588%20ss_zpszdjyl7no.jpg.html)

same procedure with spool bearings but instead of marine grease I used few drops of tsi 321 oil and dry the excess with a Q-tip


cleaned the levelwind assembly as you will do it on any reel, so no pictures, but this is how its the frame and LW all cleaned up
(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050594%20ss_zpsyoayeht9.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050594%20ss_zpsyoayeht9.jpg.html)



so, far this is the details of the reel and the internal guts, Im waiting to get some carbontex drag washers to put everything back on its place again, also I need a nice handle knob but I will get it in few weeks more, I have some expenses right now.


looks pretty promising, I read on BD outdoors  that some guy was using a reel like this for fishing school tunas, so it can handle some punishment.
Im not too convinced by the long reel foot and if I broke it fishing a nice fish it will be pretty hard to find a replacement for it.



so, what do you think guys?
put some carbontex and fish it on 20# mono line and hope to not break the reel foot or use the stock drags and save it for the shelf / collection?

Fish it. It's no collectors item and it would be fun for the experience. I'd put a bigger handle on it.

Is the foot graphite or aluminum?


Here's a pic of the Accurate project being tested in New Zealand:

@ John, thanks for the picture of the accurate mutant GT.. looks pretty good.

You're rigth, on this omoto reel,  I will fish it.
BTW, It looks odd on a rod, later I will post a pic with this reel in a rod



@Sal, thanks my friend, I already have an AT wrench but he can send me an AT signature handle knob for this reel  ;D ;)

sorry I didnt saw this question on first time

the reel foot is made on the same material than the side plates, feel like graphite.





another unique finding on this reel, the main gear thickness, I dont know what's the advantage of the side walls this thick

(http://i202.photobucket.com/albums/aa198/alextellofotos/carrretes/Omoto%20castspinning/P1050554%20ss_zpsfv8gfkfs.jpg) (http://s202.photobucket.com/user/alextellofotos/media/carrretes/Omoto%20castspinning/P1050554%20ss_zpsfv8gfkfs.jpg.html)
this is the reason Im getting new carbontex drags, the ones I have on hand have almost the same OD than stockers but the ID is way bigger.

are you sure, Sal? (no questioning your knowleage) but I just dont know if the ones I have even having less contact material work the same, worst or better than stockers)

cuz I have 3 sets of the same size than the one inside the main gear, they are almost the same OD size but the ID is bigger.
I wasnt sure to use them or getting some from Dawn at smoothdrag which are custom cuts almost identical to stockers to have more contact material

Almost all of the drag force is created by the outermost rim of the washer. The interior volume has almost no effect on drag. The inner diameter just matches up with the gear sleeve mostly but is otherwise arbitrary.

Somewhere around here we had a long discussion about this. When calculating the braking force it is the radius from the axis of the disc that matters, area means nothing.

Post by: steelfish on July 02, 2015, 12:07:42 AM
if thats the case, then I can just put some of the CF drags I have on hand and continue to finishing the reel, I just need to do every steps backwards, sounds pretty easy

one last question for you guys.
maybe you didnt notice the other thread   http://alantani.com/index.php?topic=14669.msg151091#msg151091

So, the stock drag stack size is 5.84mm (drag washers+metal washers) while the new drag stack with the HT-100 I have its only 5.07mm

5.84 - 5.07 = 0.77mm short

in order to reach the stock height I need to add a metal washer or double one CF somewhere in the sandwiched washers

if I use an extra metal washer it will be used at the end so, double metal washer on the top (metal washer is 1mm)
if I use an extra CF washer where is the best place to put it?   (CF washer is 0.80mm)
which of the both ways is better and could work safer and longer on the reel?

thanks in advance for all your help

I usually cut my own washers and what you're having would never be an issue for me, I have many different CF thickness and don't mind mixing them up.
In your case, I see a good opportunity for a Delrin washer on top. Oh, make sure you put one under the gear as well ;)

hmm now to quest for delrin under main gear and some on top, where is the best place to find them on the sizes I need?

Steelfish, this seems to be a very solid built reel. If the only week point is the reel foot. Shoot some pics of it. Might be able to modify it. I say that could easily be a 30-40 lb reel

Hard yo tell but if I have to choose one I'd say its graphite cuz its thick, solid but really light

Post by: fIsHsTiiCkS on July 02, 2015, 04:49:03 AM
If graphite I'd say it's safe to run this as a 30lb reel. Just depending on the drag you get out of it. Just such a solid internal build. Might be a great jigging reel.

I got an email from Omoto,
so, now Im pretty sure that reel foot is graphite LOL.
maybe I will take to offer of the omoto lady and order an extra reel foot and plastic levelwind gears, I think those are the only "breakable" parts on the reel, well at least while fighting a good fish.

=================================


Dear Mr. Alex,
Well received your mail.  For your questions, the material of drag washer is Telfon and the reel foot is made of graphite.  This reel was built in Y2000, for the time being, it is a discontinued model and most of the parts are no longer available at the moment.  However, we will try best to check the availability once receiving your definite parts demand.    Attached is the schematics for reference, please check and let us know the part number you need.  Thank you.
Best regards,
Teresa Lin

I assume you have the model number on the schematic that Omoto sent you.   Since I didn't see it in the thread, it is an OMOTO KTB300 SD.

A quick search of this model on google pulls up a few articles with pictures, one on a Vietnamese site, and this one on an Israeli site:

http://www.israelsportfishing.co.il/index.php?option=com_content&view=article&id=1090%3A-omoto-ktb300-sd&catid=100%3A2011-01-10-20-49-29&Itemid=1 (http://www.israelsportfishing.co.il/index.php?option=com_content&view=article&id=1090%3A-omoto-ktb300-sd&catid=100%3A2011-01-10-20-49-29&Itemid=1)

Google Chrome offers to translate this page to English (poorly), but it does have several pictures of the reel and shows the original handle.

hello Steve, thanks for the information.

even though I did recieved the squematics from a lady from Omoto it doesnt have the name on it, it just have"Omoto KTB part list".
to tell the true I havent even looked into this reel for few weeks now, too much work and some reel projects and repairs have left this omoto reel on the pending list.

thanks for giving me the name of the reel, there is not much info on it. I will try that lady from Omoto to see if she still can find for me some spare parts of the levelwind assembly and maybe one extra the reel foot, put the carbontex drags that I already have for it (thanks Sal for those custom cut CF drags) and call it a day on mods for this reel, and of course fish with it to see how bad or good it was

I knew I had the model number somewhere, I just had to stumble upon it.   I saw this reel on the omoto website years ago, and I inquired about pricing and availability a couple years ago.   Thought it would be an unusual reel on lake lanier, and something of a conversation piece.   If the price was right, I was going to order several and give them as gifts.  Too bad they were no longer available.

I occasionally search ebay for the model number, but I have never found one even  in the completed listings.

pretty sure this reel would be a great lake reel even for big cats (maybe not monster cats) but 110% agree on be a conversation piece.
I read somewhere something about this reel was on the $150 dls mark when it was available and could handle 18# tunas easily.


good luck on your search

Well, believe it or not, I never put back the reel with the new drags for 5 years  :-[ :-[ ;D ;D

I knew I have that reel pending to put it back but there was always houndreds of things "more importants", well I was cleaning some "never touched for years" boxes of reel parts and found a closed plastic candy jar with parts of a reel, I recognized the parts belonged to this Omoto reel and got in Panic, I didnt remember putting those parts on that plastic jar Yaik!! so, I stopped what I was doing and searched for the rest of the reel, luckily the frame and sideplates and other big parts where exactly where I left them (yep, 5 years ago), now my new plan for the day was to finish that reel for good 8) 8)

since the Jar had the lid closed tight, all the parts were in perfect shape, they were already cleaned and not signs of oxide or corrosion for humidity on them, gooood !!

to tell the truth from time to time I recalled having that reel "pending" because in my Box of the short inventory drag washers, I have a small bag with different thickness of HT-100 and carbontex drags that say Omotto, some of those CF washers were sent by our friend Sal and other ones were custom cut by Dawn of smoothdrag.


so, it was time to start working.

My first move was to meassure the thickness of the Stock drag stack again.

it was 5.88 mm with the stock 3 thick drag washer kit
but only 5.14mm with carbontex 3-drag washers

tried with different thickness of drag washers, HT-100 and carbontex have different thickness, tried different configutations more most of them were too much bigger 6.6mm, 6.25mm but then found a correct sized drag washer that was thinner than the stock HT-100 and used a thinner metal washer of the 309 penn reel I could found (steel ones were aver. 1.2mm and this brass washer was 0.7mm), with those 2 thinner washers the new measure of the drag stack with 4-drag washer kit is now 5.83mm,  nice !!

there you have it, the stock drag stack on the top and the HT-100 drags and parts for the New drag stack with a Derlin washer under the maingear on the bottom of the 1st pic.

I had some hard time putting back the reel, the antireverse dog was really tricky to put it back, nothing related to any other reel I had fixed before, but found a way to put it and the rest was easy, just the good old alantani treatment with yamaha grease on metal parts and tsi321 oil on bearings.

I just tossed a good amount of grease on the section where the big underhead reelfoot is attached to the reel to protect the aluminium from the salt, as well as the graphite reelfoot that meets the frame and more grease to the long screws of the reelfoot

and with that, it was pretty much done, I put one abu Garcia handle for a moment but is not perfect fit, the width of the handle hole on the abu hande is perfect but the leght of the hole is like 1/16 larger, I still cannot use this reel until finding a better fit handle for it.

I still need a bigger handle with a smaller shaft hole, I have seen some old okuma reels handle blades that might work or that require minimun modification like the one for the okuma convector or for cedros but not positive on the size of those handle holes.

now its officially finished !!

I was able to find the perfect fit handle for the reel, it was an Okuma handle for the magda pro reel, not more play on the drive shaf and hole on the handle!
now, the hard part, finding time to test it with the new drags.



Just for you to know, the delrin washer for under the main gear was sent by our friend Sal, 5 years ago when I started to work on the reel, he also sent me some different thickness CF washers, I was able to find a perfect combination of metal washers and CF washers for a new 4+1 drag stack because of the different sizes I had, thanks again Sal, a true gentleman, you can check my reply #30 from aug 31, 2020

I usually cut my own washers and what you're having would never be an issue for me, I have many different CF thickness and don't mind mixing them up.
In your case, I see a good opportunity for a Delrin washer on top. Oh, make sure you put one under the gear as well ;)

Dawn has some, but if you can't get them, pm me your address and I'll put them in the mail.

About 15 years ago a very similar unit was being sold here in Canada by the Walker downrigger company they even used the 300 Model name.

now thats cool  !! nice, thanks por posting it.


thats the same reel with different name and Lefty.

after a quick search on the web under that name and brand seems that you can still find the reel and buy one, problem will be the replacement parts.

I actually found and bought one of these Omoto KTB 300 reels on ebay a few years ago after searching for quite some time.   Still haven't got a chance to use it though.

Looking at those and trying imagine what it would be like to use one, is seems like cranking would feel more natural with your left hand..... just like spinners.  It's weird how that is.

You know! you come up with some really cool stuff sometimes!
You left some links in another thread, and brought me to this somehow lol!
So do you still have this now?
Can't just leave the book open, without hearing the rest of the story!
I saw some of them in the past,
and quite intriguing that particular one is made by the Omoto company, though!

There's one on ebay, perhaps you can send the seller a note and request a copy of the paperwork.  The box has some more information about the reel.

Or he could buy it and have two of them lol!
I really want to buy that in the worst way! Just so I can look and play with it lol!
Was trying to see if maybe it would be fun as a true caster, but I don't see any way to do that, the way it's set up!
I think you'd have to put a mag on that sucker, and set it and forget it, if you wanted to cast it lol!
I swear, I see something new and neat, on this site every day!

the correct link is this one  https://alantani.com/index.php/topic,27618.0.html
thats how I got the ted williams reel which is a copycat of the daiwa millonaire
