Thick Bricks on a prewar frame?

[Nightrider]

I have a 37 or so Huffman frame. Tried to put a set of ThickBricks mounted to 24" S-2 rims laced up with a N.D. skiptooth hub. The tire barley has enough clearance at the chain stays ( a couple more links of chain would give it even more room). However, the chain is slightly rubbing on the tire. Anyone know of a fix for this while keeping the ND skip hub?
Thanks for any help,
Johnny

You need to shim your chain ring and rear gear out a little. Easy to do on the chain ring, harder on the hub. Gary

Ok, I can figure out the front chainring. But how do you shim out the back? Looking at it, I would guess that it has to be done on the driver and cog. How do I remove the cog off the driver? If I can get it off, can I bump it out a little with a washer?
Thanks,
Johnny

I've run that setup in the past, and only had to shim the front. The chain line was fine.

You can shim some hubs - the Sturmey Archer kickback, for example, but most rear hubs don't offer shims. The best you can do is an offset cog.

I'd try just the front first too, a nice 'thick' washer put on before the bearing race should do it. If you need an offset cog, Choppers US sells them.

Thanks for the advice. Gonna shim the front. I need to bend the left arm or get another crank for clearence @ the stays. Also might modify a rear cog ( cut and re-weld on an offset) just to see if it can be done.I have several laying around, so it dosen't matter if it dosen't work.

Most chainrings are dished. Most of the time you can flip the chainring around so it dishes out instead of in.

Never mind it is a skiptooth.
