NSG, clamp a belt sander (Not too coarse) in a vise facing up, and lock the switch on. then going length wise, lightly hit the tops of the fins.
Painted my diff cover. What is the best way to make the fins not have paint? I tried taping off the fins and for about 30 minutes it was a debacle because the tape either would come up or I couldn't cut the tape close enough without it looking like ***. I then said f it and I will paint the whole thing and figure out how to remove the paint after.
Welp much easier than what I thought...lol
Started with 600 gritt, the 800, 1000, 1200, 1500, then finshed with 2000. It's in the oven now curing. I will then polish the fins with mothers. It's pretty smooth shiny now but I guess just for sake of making it so it doesn't oxidize too crazy the polish will help greatly.
I thought about clearing it but every time I have used VHT or duplicolor clear it ends up yellowing and or making the end product of color look different.
So far this is what it looks like. It's in the oven now curing then I'll polish it up shortly.

Mine was failing too. I discovered if you take the rubber pad off, you'll see a ball bearing. The ball bearing was rough and almost locked up. For a quicky repair I removed the ball bearing, sprayed WD-40 under the seal s to free it up and got some regular oil in there and turned it until it was smooth. Good as new unti I get a new bearing.my orbital sander is a pos

I figured take a small sanding block or a piece of wood with sand paper on it and slowly go up and down on the fins? Ideally I'd like to make it shiny. Then I will bake it in the oven to get the paint to cure. Figured sanding it first would be easier than trying to sand it after it's cured/baked.

), but looking closer, your aluminum may be too textured. Nigel,
Are you supposed to paint the inside? The oil won't strip the paint off over time?
Nice work and looking good!
I didn't paint the inside. Only outside. Inside is still the sand casted whitish aluminum looking color. That's the reason I didn't paint the inside, I figured over time or pretty quickly all the paint would end up turning into something with the diff oil and then make a mess/cause a problem.
That 392 should be pretty powerful down the track...lolOUTSTANDING!![]()

Anybody interested in a small assortment on Pinewood derby stuff? Polished tool steel axles, tungsten weights, Teflon bushed wheels, finished car body. Never could finish better than mid-pack because I don't have access to lathe or a machine shop. The dads who built the winning cars wouldn't let their kids touch them, LOL. They were works of art and got faster as the races went on. Of course, nobody cheats.Started last minute for Saturday's Pinewood Derby. We have an adult class. I always bring something crazy
Have to bevel the inside of the fenders so they don't touch.Not sure that would go down the track without getting hung up...
They ride on a six lane aluminum track. Basically your wheels bounce down the raised center of the track keeping it on course. As long as the fenders don't interfere with the wheels you are good to go.It looks super cool but doesn't it high center in the middle anywhere?
These are my two, the black one was made in grade school as a cub scout. The wood one was for the "dad's Race" the year my son made one. We both won! Mine was better than a foot faster than any other car though.
I was going to also run the old car to see how it would stand up after decades, but the plastic wheels got brittle and the "hub" inside disintegrated so the wheels wobble... I'd love to find vintage wheels and replace them...

Right. I have three boys. Ages 11, 8 and 4. I'm in it for a long time. I've played with different ways of building and weight placement. Every year is different. Just never know till you run it down that track. I've had some awesome cars be the slowest and the most stupid be the fastest.Some nice looking car there!
Ours was a wood track with the raised centers (Both generations). I found that keeping the weight to the back generally helped as light front wheels were less likely to drag on the center divider.
