Hi Bonnar Nightmare, Here is a pic of the 14" Model 40 Scott Bonnar, is this the machine that you have?

This particular machine is for sale at:

Bruce, This is the same type of machine that I had originally and was looking for a catcher.....impossible to find...I eventually gave the machine away.
BTW, It would be a mammoth task to retro-fit a Model 45 clutch, as the shaft is different diameter and not much room.

Hoping this may help wink
