c'mon chris. i'm waiting...
actually i've got some more pics to post when i get a chance. my beautiful girlfriend got me a digi camera for the holidays. how nice! now i just have to figure a way to connect the hardware. in time.
the spool is here!
man, i'm excited. just yesterday i got a great idea for its construction. instead of using a diff and screwing both halves together through the diff holes(lame), i decided to use the one way pulley. ahhahha, it came out sweet!
once i found out that the hex was 1/2" on the pulley, i got some aluminum hex standoffs and away i went. they had a threaded center so i ran a .125 pin through them and put them on my com lathe. 15 passes (each) later i had my .391 diameter outdrive blanks.
how cool. then, with some dremeling and finish filing i had the slots at .123 perfect for the blades. i wish i could post the pics right now. it's so nice. rc lab should make some and include them with the kits. what a great tool for beginners instead of the one way. only the few kits out there are being run on asphalt with large turns. i've seen those european circuits. huge!!!!!! oh well, for now i'll be the lone manufacturer.
another stroke of brilliance?
perhaps. as you know i've been complaining about the dirty diffs with the larger pullies. well...i've finally come up with a fully sealed system. and it's simple and extremely cheap.
nothing more than a piece of monokote sticker stuck on the side of the pulley. works best with the delrin outdrives as the outdrive flange is thicker for the i.d. of the sticker to seal on.
this was today's discovery. i found that a no. 21 oring fits snuggly inside the pulley and is only 1/16 thick. after the diff is newly rebuilt, i just shove it in and it seals the gap. to keep it in place i just run a bead of ca where it meets the inside of the pulley.
voila. virtually 100% sealed. i tested the sticker on both sides for the last few weeks. today i pulled them out to reveal that the short side was immaculatey clean. now, with my oring on the long, i'll hopefully stop bitching.
pics to come soon.
btw - i've also constructed a wider bumber from polycarbonate both top and bottom. a bit on the heavy side, but even better than my original c/f top plate. this stuff flexes! hummmm.... not a bad idea for a bumper. hehe. live and learn eh?
