Inch pitch freewheel?

[64Pete]

Hi,
Just wondering if anyone has done this.
Either an inch pitch coaster brake cog that happens to fit some brand of freewheel.
(I have enough Suntour FW I can sacrifice one or two)
or
By cutting every other tooth off a 1/2" pitch freewheel cog.
Looks like I'd need an older cog with a taller profile.
Possibly two 3/32" cogs sandwiched together so the wider inch pitch chain fits better.
or
Bolting / welding an inch pitch cog onto a freewheel cog.

I'm trying to keep the inch pitch chainring and chain on an early JC Higgins MTB replica.

Thanks

Pete

Done here frequently on even numbered rear cogs, but doesn't cut it for drive (front) sprockets. 1" pitch cogs are 1/16" thicker on average than 1/2", so the fit is a little loose. :|

Sandwiching two 3/32 cogs together may give you the correct 3/16 width depending on tooth profiles but removing every other tooth will not give you the right cog. So called inch pitch chains are really a mix of .600" and .400" links adding up to a total of 1.000". The driving cogs use .600" tooth profile not a .500" profile.

I think a cog set up this way would likely work, sort of, but it would be noisy and would have rapid wear.
