Reel Repair by Alan Tani

Hey guys, did any thing ever come of 113h stainless being ordered?

Still working on it... Not as easy as one would think. At least to get them at a fair price and precise.
I'll keep all posted on the progress. Sit tight!
Thanks
Dom

I'd think your minor weather problem did not help.

If they do come through.... please sign me up for two sets !
Vinaka !

Thanks and please do keep me posted.  I just orded the other items needed from Alan..

You couldn't be more right, Lee!
Also, these guys must be doing well because a quote takes over 5 weeks from all manufacturers except one, so far
I'll keep yas informed!
Thanks
Dom

What are the gear specs you are sending out enquiries on?

Just wondering.

I made a set for the 115 a couple of months ago.

Are you just teasing us with those Mr Janssen...as usual, or would you be willing to offer them the members here?
Just wondering.

As previously explained when this subject was up previously, I only do things that interest me. If it were only for money, i would probably want a lot of it.

The gears for the 115 were only for the sake of completing a reel i really care very little about.

Really, i was curious as to why it seems so difficult to find someone who can make these for you.

Gotcha!
Since you care very little about that reel, let me know if you are ever going to part with it.

It's not that we can't find a gear shop that will make them it's high minimun numbers.  Can will you cut gear stock that we can then finish off on a standard lathe?

Some are small.

I did contact a manufacturer in China via a USA rep.  Sent a set of gears for the company to look at and take specs from (I did get the gears back after several months).  Was advised that the cost for the initial set, up to about 10 was in the neighborhood of $250 because of the cost of setup.  Apparently, the gear hobbs are special sizes and that's the biggest cost.  They recoup their cost by the cost of the equipment prorated over the number of sets.  After that, the cost comes down drastically.

I was willing to go with the 50 set price, but somehow the USA contact felt it wasn't worth the bother and just cancelled the whole thing.

My sense is that cutting the helical gears is the costly part.  If the gears were just straight cut, those should be much more readily available as stock items (I'm checking into some of that presently).  Of course, there would need to be some finishing on the lathe, and milling to cut the slot to engage to the spool.  The gears wouldn't be as smooth/quiet as helicals as well.  Still, they should do the job.

Ah, i see... Hmm, thats too bad.

(kinda sad in a way- you see all kinds of posts about unemployment and  the downfall of American manufacturing, and then when you have a job that needs doing, nobody can / wants to do it. WTH?)

About the gear stock, thats an interesting idea. Good thinking. I like to recall though, that that sort of thing often turns out to be a lot of work anyway, not leastly since subsequent turning operations inevitably form burrs and stuff on the back side of each gear tooth. Besides, there isn't much to hold on to in the lathe (i guess you were thinking of cutting the bar stock into gear-sized slugs) and you would lose planar reference too. Unless you held the whole bar in the lathe and worked from that i suppose.

My hobber is very small, by the way. Very precise, but small. Maximum length of job is like three inches, and it doesn't do helical gears. It has been on my project list to build a larger hobbing apparatus that does do helicals, but it seems like i'll never get around to it.

About the specs, well maybe that is part of the problem too- maybe folks get too fixated on following the original recipe (what are they, 32 DP with a 14.5* PA and maybe 5* helix?) to realize that maybe module 0.8 will do just as well. Some folks have no imagination these days.

I don't remember what i used on the 115. Probably just straight module 0.8, at a ratio similar to what it was originally. Really, there isn't much room to move around in there.

(gear ratios are no great mystery really- they are made up of the size of one gear divided by the other, that's all. The size of the first one is dictated by what fits in the sideplate.) And, this needs to work at a given center distance.

I don't know the measurements of the reels involved. (114? Or 113? Or didn't i post once before that they were the same? I don't remember. But i think the center distance on the 115 was 1" (very difficult to measure accurately, btw, because of the way the reel is built) and the biggest gear that could fit in it was about 1.5" OD.

I'm not in my shop very often nowadays anymore. Maybe once a month. I happen to be there now though. Maybe i'll look into it later.

So who could do this? Oh i dunno... Has anybody asked Cal? Or what about that fellow Alan knows? Maybe he has a cnc mill with two interactive spindles. Then he could teach it to hob gears.

I'm gonna go have a beer. Typing posts on an iPhone takes forever.

Doc.

Your 3" limit will be tough to get around.  There is a gear shop in Portland, OR that can do the entire gears, If Dom can't get it done I'll drive up and get something started.  I tried getting some cut in Thailand and there was no intrest in doing less than 1000 pieces.
