To Grove or Not To Groove

[pinechopper]

OK I hope the cars flies down the track, not thru

the air. lol FYI dd4h axles exactly 3 degree neg.cant on rears. If , and thats a big IF the axles are in fact hitting at two points only that would also compensate for a screwed up bore. And a good polish would certainly help. Thanks for the brainstormmin' session.....

I was using 3 degrees as an example, but 3 degrees will work fine. I have used several different cants over my pwd career. I don't know what the standard cant is with the pin supplied with the SilverBullet? I am sure someone will help me with a number...

Silver Bullet supplied pin is 1/8 in. -- 2.9 deg.

Off topic but one thing your drawing really brings home is the importance of tight wheel gaps with grooved axles, otherwise running the risk of the hub edge falling into the groove during a wiggly run.
