I've put together a 3.7:1 gear set using a jigmaster 5-500 main and an older surfmaster 13-250 pinion with 13 teeth - the 4:1 jigmaster and newer surfmaster 13-500 pinions have 12 teeth. I got the idea reading the linked thread on the 250 recently http://alantani.com/index.php?topic=17571.0
The 13 tooth surfmaster pinion is on the right;

I had also been working on a three alternating dog bridge using a stainless Cortez Conversion 98-155 gear sleeve with 9 teeth on the ratchet. I used the 98-155 because the smaller ratchet allows more room for the dogs and springs. Looking at the close up photo I can now see the second dog needs to be fine tuned to sit flush with the face of the ratchet teeth.

I filed the flats on the sleeve shaft all the way down to take one of Alan and Bryan's thin under-gear metal washers made for the gen 2 sleeves. It got a bit busy under the gear with 3 dogs and springs and I wanted a metal washer to cover it all and protect the delrin washer.

The bridge was intended to be drop in but I ran out of room with the spring for 3rd dog and needed to grind about 1/8" off the plate near the bridge screw -again! (this was my second attempt)

Put it together with a 3/0 Alan T grip and SS handle.

When I first put it together the spool and pinion didn't engage - I had checked the pinion fit over the bearing/bush in the side plate and fit on the spool shaft before I started. I pulled it apart, couldn't see any problems and put it back together and it worked fine. The yoke might have been getting caught up ???
The gears ran smoothly in a light test - I put it on a rod and winched a 2 litre (~4 lbs) water bottle around 12' vertically a few times. I had done the same with 5:1 newell gears in a 501 the day before and as you would expect, the 3.7:1 gears take noticeably less effort to winch a dead lift.

Mike, 3-dogs on that tiny plate? you're a mad scientist ;D...I love it!
Keep it up, your projects are exciting to see.
Sal
Mike - So you had a 3 dog night then ;)

Thanks Sal, but I wouldn't call myself a scientist ;D

Haha - no it's summer here, that's why I put the dogs out on the bridge.
Sick brother. Sick!!!
I would love to hear that click click click
Mad Scientist for sure! Some really innovative and outside of the box coming through these days. Flippin' sweet by any standards. Thanks for sharing with us!
Post a video with sound... ;D I too would love to hear it!

Micky The Jigmaster!
I know you've had this one on the go for a while, it's nice to see it revealed to everyone. I reckon I'll give this a shot on the Frankenjiggy down the track.
Good work here!
I too would love to here the triple dog music...I know alternating doubles sound awesome. I love these innovative builds...great work!! 8)
I still see some room for the 4th dog over there

It's not that loud really, the springs are soft and the ratchet teeth are small, but it is fairly constant.
Andy and Mo, I'll see what I can do about recording it, and maybe compare it to a 16 tooth 750 SS ratchet - now there's a machine gun!

Four? - now that
is mad, and just silly ;D;D...........although I might have looked at it when I was hoping to make it a drop in bridge, but couldn't see how to fit the fourth without modifying the plate. Now that I've modified the plate anyway, a bit more grinding can't hurt. Hmm...standby.
Mike
Different bridge but same concept - I haven't cleaned up the 4th dog and need to trim a little off the post - but yes, Alex and Fred, there is room for a 4th dog! I'll clean it up, modify the plate a bit more, and file the flats on the sleeve so I can cover them with a metal washer later in the week - but it seems to work okay - even if it is a bit silly ;D ;D

Man, you have some serious skills?
A lot of people say Newells sound like a coffee grinder. This one could really play a mean tune. ;D
Nice work Mike!

told ya!!
I dont see anything silly in there, pure genius!!
now I want to hear the sound of that revolver gun
I'm really gonna show my lack of knowledge but I'll ask anyway.....
What's the reasoning behind having that many dogs?
PJ,
It's to reduce handle back play and more of an instant drag engagement.
Mike, neat creation! Just a question. In the "4 Dog" photo it looks like the bottom left dog would hit the top left dog when the reel goes in free spool but it probably just misses? :-\
Ain't no back play in that Jiggy. 8)
Dom
Wow ! That is great innovation and workmanship .
Just like hot roding , if more is good too much is mo better .
I love it Buzz
Thanks again guys,

Bryan's right PJ - all that these 3 & 4 dog bridges do is reduce the handle back play, there's no real advantage other than personal preference. On the other hand, double dogs that have simultaneous engagement, like Alan C's Pro Challenger double dog bridges, and most of Sal's custom double dog reels, improve the strength capacity of the reel by supporting the gear sleeve at two points and sharing the load over two dogs - a good option when using Bryan's five stack drag, Lee's insert or Alan C's JM500X gear set to their capacity of 20+ lbs of drag in jigmasters (& higher in senators).

Thanks Dom, It's close, the second dog did hit the third dog (not by much) when I first put it together, I filed a bit off the underside of dog 3 and reshaped the top of dog 2 so they just miss each other. The four dog bridge was the first three dog attempt and I shaped the second dog a bit better in the next one. And yeah, not much back play at all - I'm starting to like it more. I haven't got it on a reel yet, one of the posts are still a tad high - the under gear metal washer rubs slightly when the drag is tightened.
Mike
Mike,
I figured you had already worked things out, but had to ask. It's really amazing how you got them all in there.
Nice job again,
Dom
And here I was thinking 3 dogs on a 115 bridge was a bit tight...
Nicely done!
The prophecy of old draws near, that one day amongst you shall walk the man of the 5th dog, and power over the fish of the sea shall flow from his hand....LoL :D
Yes obawon, and those that worship the false dogs of gilded IAR reels shall be cast into perpetual comfort and practicality. ??? ;D ;D
Welcome to the AT site - a hall of reel wisdom with members that collectively know and understand the mechanics and application of most reels, sometimes more than the manufacturers do.

"Pappy said "Son, you're gonna drive me to drinkin' if you don't stop drivin' that ...hot...rod...jiggy" " ;D
Looks like it was a fun project.
