    Hello all,

    I have been lurking on this site for over a year now and decided to finally sign up and post. Last summer (2008) I machined up a friction mount system that is very similar to the ones sold elsewhere on the internet. I put this on a Schwin Clear Creak with a Subaru 35 4 stroke. It has worked mint and put about 600 miles on it. I build another one for my Dad and he now also rides with a Subaru 35 friction drive. I began having problems with my motor cutting out on full throttle and couldn't sort them out. So I purchased a DAX 50 titan motor and bolted that up. It has been working mint ever since.

    I have a small hobby machine shop in my basement, Lathe and Small CNC bench top mill. If anyone needs any custom parts or machine work please ask..

    The main channel is .250 extruded alum CNC machined for bearing holes and engine mount holes etc... The uprights and front mount bracket are 1" X .250" alum bar stock. I put lightening holes through the uprights.
    I now have a DAX Titan 50cc engine and a 1.125 roller.

    Great work!
    Where did you get the extruded channel from?

    The extrusion wasn't a channel but a square tube that I machined 1 side off to make it a channel. I bought a 4 foot section from discount
    Then cut it up and machined it.
    I made 3 kits with it and still have about a 12" chunk left over for my next project.

    I notice that you have usesd a chainsaw type friction clutch.

    Does that slip a lot, burn up, etc ?

    I've been reading here for a couple days, and have read advice not to use the chainsaw clutch for those and other reasons.

    I keep thinking that it should work, though.

    Does it give up on you, on a steep hill, or have other problems ?

    Thank you.

    I know this is an old thread, but I'd still like an answer to this question.

    Thank you. :grin5:
