KMG Rotary Platen wheel distances?

[Drew Riley]

Can somebody with a Beaumont Rotary Platen attachment tell me
what the distance (on center) is of the wheels from one another?
I'm thinking of putting one together.

Thanks in advance!

I'll try and take a measurement tonight if I get home at a decent hour, but roughly it is 2", 3", 4", 5" The two longer measurements vary slightly depending on the tension you adjust the grooved belt to.
