Dum question: Attaching moon discs?????

I'm putting some moon discs on stock rims with screws.I'm afraid of having the rims leak air. How do I do it right??

 

Go to the tool store and buy a drill bit stop (little collar with a set screw). Set it for the depth you want so you only go through the rim and not the tire bead. Your other option is to dismount the tire drill the oles and then remount the tire.

 

Thanks,so it's OK to drill all the way thru the rim? That's what I wasn't sure of.

 

Just make sure you use short screws.

 

10-32 is the best screw size

 

Thanks,I just didn't want to "screw" this up.

 

I went to the hardware store and got some self drilling, self tapping screws. They have a little drill bit on the end. Anyway, I drilled the rims (they were on the car) untill I was through the metal, pulled the screw back out, cut off the drill bit part, then screwed the screw back in. I did 5 wheels like this (one spare) and only one hole leaked, so i took the tire to a tire shop, and had them rotate the tire a few degrees, putting the hole under good metal, and it was all good.

 

As long as the tire has a good bead, you'll never have a problem with leaks.

 

Great.Thanks to all for the advice.

 

What a coincidence - i was at the trailer parts supply house at lunch and they had moons on smooth wheels for diplay. They were attached with some little spring clips that attach to the ring and wedge into the wheel sides - no leaks there.

 

yeah, they are availble in clip on style as well

 

A guy in my club bought a lakes racer from the '50s. It came with two pair of "Divco" wheels. They were preped for moon discs by welding 8 nuts around the edge of the wheel where the balance weights would normally be. This spaced the moon disc closer to the aerodynamic edge of the wheel. I'll post a photo of one tonight.

 

OH, and whatever you do, make sure that you use a template to drill your holes. Make sure that the holes are evenly spaced around the rim, and that you use the same pattern on all the wheels.

Otherwise, each disc will only fit one wheel, and only in one position. Could be a PITA!

 

So, it's tonight, and here's the photo. I don't know if it's clear in the photo, but the nuts welded to the rim are flush with the outer edge of the rim. The outermost possible edge to make the wheel as aerodynamic as possible.
