Re: Axle crimp marks

I used to file crimp marks off.

Now I just polish over them with the rest of the axle shaft.

I DO, however, make certain to remove the flashing. The flashing is much worse than the crimp marks.

Wood glue, Elmer's Glue All, School Glue...whatever white glue you have at hand.

Re: Drill Size vs. Axle Size

I honestly prefer #43, even for BSA. It works great for Maximum Velocity axles too. If you drill a hole and it's a tad loose, it's pretty easy to snug it up a bit. My preferred method is just to dip a toothpick in some glue, insert it into the hole, twist it around, pull it out, let the glue dry and...

Re: Hub coning?

I've seen wheels that are coned on the inner and outer hubs .. but it's a bit tricky, and when I tried it, my results weren't optimal. I think I've also seen beveling as part of the inner-step removal, but always figured that slightly tapering the underside of the nail head was an easier way to gai...

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,...

Re: Redeeming Slots?

Well, turns out that my 3D printer can't print small enough to properly do these little axle guides I have in mind. Maybe if I can find somebody who has a resin printer...hmm, I should check my lbrary's makerspace...

Re: Straight runner - wheel canting?

That said, I've heard it is is possible to make a side-rail guided car, but this is a challenge I've yet to undertake. I'd sort of like to build a test car for it sometime. So I'm not the first person to have the idea of making a "wall rider!" I was trying to work it out in my head, but t...

Re: Straight runner - wheel canting?

I've heard some speculation that canting the wheels helps to make them run more true, since you're focusing the axle contact on a smaller surface area, but I don't really have solid facts on this. When we camber wheels, it's to keep them off or on the rail (rear vs front, respectively). That said, I...

Re: Redeeming Slots?

:thinking: Would this tool be placed in center of the slot pointing up, so that the pointed tip rides up on / along it when the axle is inserted? If so, when you insert the axle from one direction, the nail might push the piece out the other side. It might need to be long enough to reach all the wa...

Redeeming Slots?

So, I know that for most pineheads (myself included), slots aren't very popular. Usually the first thing we do is flip the block over and drill holes for axles, ignoring those annoying, janky slots. I am fortunate enough to own a precision-made axle drilling jig with hardened bushings for this purpo...

Re: Drilling Angled Holes in the Original Slots?

My go-to for filling in axle slots is a toothpick or two (sanded thin if need be) plus epoxy. Sometimes I will mix the epoxy with fine sawdust to volumize it and provide more of a "woody" look to to it. I don't know if it matters or not. BTW, I corresponded with the maker of the clear jigs...

Never been a huge fan of the Space Derby. It's fiddly.
