Rear skip sprocket fit later coaster brake axle?

[drob54]

Hello,
I'm trying to adapt a more modern coaster brake rear wheel, to have a skip tooth gear. (basically a newer wheel onto a 50's Schwinn frame)
Do the old skip tooth sprockets thread on to, or mount the same as newer sprockets?
Are they a similar dimension, etc.?

The old skip tooth rear cog is thicker. some people grind off every other tooth on a modern one piece chainwheel and cog to get the look.

I picked up a wheel that someone had taken a skip tooth cog and spot welded to a newer driver for a regular and newer coaster hub to it. They made have had to grind on the skip tooth cog to get it on there. It worked well for me, and I also transferred the guts to another new hub for a build off bike.

You probably want the conversion cog Ichi Bike sells. They are truly made for skip tooth, but have the modern 3 spline design for a Sturmey or Shimano hub.
