    i built this roller from local hardware, little taiwanese ball-bearings for $3.50 ea, some thrust washers, bit of hardware & some heater hose. boy is it ever quiet!

    a 5/8" length of heater hose is the rolling surface...overnight it was great, so i got a wild hair you-know-where & decided to fix the top chain-run's tendancy to "harmonize", it gets pretty squirrelly at 19-20mph. both dan and i have had chain damage because of this.

    i grabbed a couple "brackets" and headed for the hardware store for more stuff

    here's where i'm at right now, haven't even tried it yet

    time to go back to jack's for a spring, more soon...i hope.

    it works better than expected...it absorbs that start-off chugging, and it all but eliminates decceleration backlash :D

    i'll report on how the heater hose holds up.

    the run from the tensioner to the engine sprocket is consistently straight & true

    thanks, bro...she's really coming together :D

    i'm sure glad these vehicles are so tiny, because they still are money-pits, just tiny ones, thankfully :lol: :lol:

    cost of this mod: $19 8) 8)

    Slick solution for a long chain run.

    First I've seen of the shock suspended seat. That is first rate!

    good excuse for another test ride :)

    40 miles, not one problem :)

    well, maybe the heater hose. i'm gonna put fresh surfaces (new hose) on the rollers tomorrow. i think if i have them centered right they'll last a good long time. if not, i'll find something else because i love the bearings, they're smoooooth 8)

    The new spring looks like it will last a little longer. That is a sweet, clean set up Augie!

    i'll happily report that the rollers work well, the angles and direction of pull seems good. i'll have to find something else for the roller surfaces, tho. the heater hose is fine all the way down to the nub, but i only got about 60 miles out of it. i have some nylon cutting boards, all i need is a coupla hole saws.

    Hey Augi, why not try running on the steel with a little grease?

    i did, mike...but i need something to keep the washers spread, they slip onto the bearings and are kept in place by the hose...i'm on the lookout for some brass or copper tubing, that might be nice.

    Augi, I wonder what would happen if you used something like JB Weld, to fix one washer to one bearing, and again on the other side? Let it cute overnight, and then maybe all would be well?

    'fraid not, mike, not with these particular bearings, they're designed to be placed in the end of a pipe to make jackshafts or axles. when they're placed face to face there's a sloppy gap, and my only option is to sandwich a 9/16" length of "roller" (hose or pipe) between them. i do agree a smooth metal surface could do a nice job, tho.
