Awesome posts!
Sorry I've been slow to respond. I broke my right hand, a fracture of my 5th metacarpal!
In the mean time, my wheel set, stem and handle bars have arrived, but no real testing them out on the Fox 40 now, until my hand heals up. Damn the luck! :|
I've got every one of those links you guys posted in my favorites now! I haven't let up on the research, just a little slowed down. I'm getting closer to a final design that will allow me to fit all this on a custom lower swingarm.
Thud,
-Thems be some cheap sprockets and stuff on surplus center, nice!
-I think I'm going with 5/8" keyed shaft?
-What is the smallest #25 motor pinion sprocket you would use for boring to 12mm? 15T, 14T, 13T?
-I've been looking at Ebay for the torque limiters. Very nice! Morse or Dalton recommended? If I get one with a smaller bore than what I need, do you bore out these as well, and add a keyway?
-Thanks for the info on ecrazyman controllers, I'll look into it. What's the best way to find this guy?
-You've always paid less for you WI FW? Or you've never had your very own?
-On the shock absorbing adapter, I've looked for elastomer's, but I'm not finding anything that turns my light on.
:| How would elastomer's work/fit into a design of something like this? Your thoughts?
-HA HAHAHA! Yeah, everyone knows that!!! 8)
-For my 2nd gear dog clutch setup; This, OD= 2-7/64" ( https://www.surpluscenter.com/item.asp?item=1-3421-G&catname=powerTrans ), and this, from what I have been able to summarize, has a usable dia inside the teeth of 2-3/16" ( http://www.mfgsupply.com/gomini/gominisprockets/gominisprocketsidler/az2186.html )?
-One more thing. Do you think an ebay (Morse or Dalton)
"225" torque limiter is enough for the spur of the 1st stage? I think, maybe these
"225" size TL's are the same as the
6524K12 on: http://www.mcmaster.com/#torque-limiters/=fym0sr ,third one down and can handle ~60ft lbs?
Etard,
-Cool, thanks! That sounds like great chain! Expensive!
-On ^that^ #25 sprocket, it's NICE! It should work, I'm thinking you would just need to make sure your not going to push your brake disk too far out. A "Top-Hat" can help with this, but then you would have to find another sprocket (like the ones he can make to go with it maybe).

I've found a great source for some hard to find #25 sprockets (hard to navigate sometimes with 9,728 results in 3,147 families, but here's the #25 family listings):

BIG question: Is this a typo on this website that these guys sell a WI ENO "Deluxe" FW ...
w/ "FOUR PAWLS"??? http://harriscyclery.net/product/white-industries-eno-deluxe-singlespeed-freewheel-721.htm
Here is how far I've gotten with my drawings. This is a "photo match" of Farfle's custom lower using a pic he posted a while back. I needed to get it into my drawing so I could see if it would work, and how I would have to change it to make it work. So here is Farfle's lower
"as is" in Google SketchUp:
Note: I've resized the wheel to 20.5", like on Farfle's race bike. I will have the 2.5-16 "Bridgestone TW9 Trail Wing Dual Sport" tires on 20"x36mm BMX rims.
(Anyone know if this combo should work before I purchase the 2 wheels and 2 rims?) http://www.motorcycle-superstore.com/2/29/393/14725/ITEM/Bridgestone-TW9-Trail-Wing-Dual-Sport-Front-tire.aspx?WT.ac=Cart_Item and http://www.ebay.com/itm/BMX-Rim-Wheel-Alienation-Runaway-20-32-hole-/280588625991?pt=Cycling_Parts_Accessories&hash=item415462a847 (I need 32 hole front and back)
Later,
