Re: Lifted Wheel - Treated or Stock - Does it Matter?

Is there any advantage or maybe a little bit more speed that can be gained.. by also toeing in the lifted wheel slightly so that air is deflected around the lifted wheel cavity. I'm thinking by toeing it in.. that if it were to also hit the rail that the contact patch of the wheel surface to the rai...

Re: Axle crimp marks

Yeah FS, I know all to well what your saying about a metal jaw vise and it marring up the axle shaft . And I for one and like most have had the worst of luck with trying to cut a K -house groove in a pinewood derby axle head with the large loop type hack saw. This year I'm trying to get away from sh...

Re: Axle crimp marks

Thanks FS, I really like that idea and method.. I've never heard of or even seen it done that way on a bandsaw! ( I'm going to have to change my ways and method some day! ) I just use a large hand twist drill to hold the axle and use a Dremel with cutting disk to cut in a groove in the axle head. ht...

Re: Axle crimp marks

VK ,
Have you got any good ideas for making a tool to hold
the axle.. for cutting a K House Groove in the axle head.

Or do you even use this method for adjusting axles?
I can’t count the axles I’ve missed up.
By forgetting to do this step first if I wish to run a car with the
K House Groove’s.

Re: Axle crimp marks

Like you BSAdadGriffindork, My method for flashing removal is the same stationary with a file Chucked up in a drill press. Don’t forget the burrs on the axle tips! And like VK’s method to give shape to the axle head spinning it a drill press. However after I’ve removed the flashing .. While the head...

Re: Straight axel rail rider

Well if you’re going to drop $ on the turbo jig.
You might as well splurge on the $35.00 axle bending tool.

Some of the derbyworx axle bend tools run
around as high as $85.00 that iv seen on web sites.

Back in the day I just used a vise, Phillips screwdriver, and hammer
To tap and bend the axle.

Re: Hub coning?

Is there a particular “plastic” polish that you like to use? Well to be trueful over the years I've been racing now.. I really don't have a particular as I've tried several types and different brands of polishes and wax's for the wheel bores. As seen in the image below all of these have had there s...

Re: Axle crimp marks

The 2 crimp marks on the axle shaft will be vertical to the back side of the wheel bore. ( or to rear of car ) Straight up and down from a side view of a car. Some have said to run them this way.

And if I recall Stan Pope would say..
Just orient the axle so that the crimp marks are up top.

Re: Axle crimp marks

With grooved axles.. the groove is all the way around the axle shaft. With the 2 crimp marks on the shaft of the axle it’s not like a grooved axle. Your are right that by leaving the crimp marks it keeps the shaft diameter larger them removing them. So this also helps with how the axle fits the whee...

Re: Hub coning?

I've seen wheels that are coned on the inner and outer hubs and I have to admit they look like they'd probably help minimize contact. I don't think it would be easy to do with hand tools, though. I know you can modify the Derbyworx hub tool to cone the outer hub as opposed to just removing the step...
