Matthew.
Thank you for your reply and I figured the distance between the wheels as being the most critical and the rest I will just wing it as I go along. I have already started on my copy of your excellent version but another couple of questions if I may please.
The diametre of the motor pulley attached to the bottom wheel looks to be about 14' dia, is that about right? I ask simply because I will be using a one and a half HP induction motor on 240 single phase and of course unlike your motor doesn't have variable speed and I have no real idea of the optimum speed for a bandsaw.
I am or will be making 16" wheels.
I have not been able to find a supplier of bandsaw blades here in Thailand so guess I will have to import from the states. Thank you for the size of the blades, a good reference for my wheel spacings.

David.
