hey guys,
I've been talkin back and forth with willthethrill (realy cool guy) about how his freinds dad made a custom 84 tooth spur gear in his machine shop. i would realy like to make one of these gears in my machine shop, so i was wonderin what kinda mathmatics do i need to do and how do i keep 48 pitch. how would i find out how much larger in diameter i would need to be to add the extra 8 teeth. will the thrill was tryin to explain it to me but then he told me how he was only 14 and didnt totaly understand the process going into making one. so i know theres other machinists with alot more expierience than me who maybe could explain how i would come to the dimensions i need to make one. thanks
:cheers:
 
he wants to do some serous rock climbing, and i did use a 84t spur gear. it was insane, but be sure to reinforce ur tranny.
also i exactly dont know how my friends dad did it. i think he has some very expensive software he hooks up 2 his machines and he can knock out stuff from a block of metal. we had 2 adjust the truck to be stuck in 2nd gear because the second we nailed the throttle on any surface it shifted, no matter how fast we where going. also we like superglued the slipper plates to the gear, because those pegs where not strong enough.
 
Just a bit of intelligence to apply here. If you had drive train problems, the culprit most likely had to do with the gluing of the slipper plates to the gear. That completely defeats the purpose of the slipper clutch system, and is a sure way to invite disaster into the tranny casing.

If you want a better slipper system, then get the RRP double disk slipper set up. Beats the snot out of the slipper pegs and is specifically designed to handle the heavy weight of steel spur gears.

Next time just try tightening the plate all the way down, it won't move.
 
we tried it. it blew all 12 clutch pegs and the spring was bending it was so tight.

i know that, but it was low end. i am putting it in my sportmaxx that i own, because the pegs blow. but we have rrp gears.
 
Tried what? And know what?

As far as the pegs go, they are not designed to be sticky. They are designed to apply a bit of friction the the plates. If you overpower them (which is not unusual), they will melt out. As I stated previously, try the RRP set up. It works like a champ, no glue involved...except for gluing the friction pads to the disks.
 
Custom or not, it is a spur gear, right? If it goes on as a spur gear, then it can be used with the slipper disk set-up. The slipper disk set-up doesn't use slipper pegs.

BTW, you can redo your signature at any time.

I must just be wasted, but LOL!
 
You aren't wasted, but I am glad you found the reply humorous. Hopefully, it will get through to the intended target.
 
LOL...it worked.

Yes, you can get it without a spur gear and apply it to your regular stock, custom, or aftermarket spur gear. You can even use it with the slipper pegs if you want to.

You could also go the full route and get the ring spur gear set up to go with it.
 
you can easily use a stock slipper on a custum spur. all that you wont have is the slipper pegs. just make it metal slipper plate on metal spur. it will get realy hot(if it slips) but my geusse is you could easily lock a metal to metal contact.

What about radio noise? not an issue?

Not recommended. Ever felt your 1:1 vehicles brake disks after a day of driving? Pretty hot, huh? Now imagine that scaled down in size and right next to your plastic fuel tank, plastic tranny cover, and any other parts. Something might begin to melt...then again, it might not.

Metal-to-metal contact of the flavor you are describing is asking for a number of problems. Heat and EMI are the big two that spring to mind for me.
