Derby Talk

3 years ago I bought 12 of the vintage kits from BetaCrafts (sold 6 to a PWD friend). If you call them you can order what ever quantity you want.

Since our rules don't allow altering the wheels except for a light sanding on the OD, we can't technically remove the step on the outer hub. Has anyone tried a lower negative cant on the rears?? Maybe 1.5 degrees?? That may be counterproductive since the 2.5 degree angle was to lift the outer edge o...

Well, I like my platform on the drill press, I can just adjust that to give me toe in or toe out. No shims. however, there seems to be a limit. After about 1 to 1.5 degrees. I have trouble. So sometimes I still have to put a really mild bend into the axle. Are you using a carbide drill?? They are s...

It is to scale.

What is the disadvantage of having the rear wheel gap at 1/8" vs. 1/16"?? I usually narrow the front but also use a 1/8" gap for the rear wheels to be more sure they won't touch the rail. They probably still do since the back end of most cars will wobble a little as the car goes over ...

I use surplus carbide insert I got from work, but add the last 0.1 ounce with lead tape.

We used the rail rider tool and the rear axles are bent 2.5 and fronts 1.5. Are both front wheels set up with the bend in the same direction? I would use positive cant on the right front wheel (axle pointing down) and negative cant on the left wheel (axle pointing up), guaranteeing the right wheel ...

Specifics?? Positive camber is proven faster. Have you done any track testing?

Another way is to use a white "sharpie" marker.

More like 6 years! Time fly's!!!

I do exactly the same except I use a .096 polished gage pin. Does that leave much room for the graphite - how are you getting it in there ? Is this after reaming ? Hmm... Wait a minute! I use a .096 pin to burnish the bore to smooth out any imperfections before polishing. (No reaming.) Then Doc Job...

A little too far for me!!

What are those wheels on the car on the flyer??? They sure aren't BSA!!

Hmmm... Still no pictures!

Carbide or HSS??
