Hello Buddeyboy

A warm welcome to the ODK forums!
I hope we can be of help here.

So you have a Model 33 and a Model 40.
So, what are the plans?

The Model 33 is the precursor to the famous Model 45.
It's a great design, and still a very good performer (by modern standards).

The issue, now, with the Model 40 is the primary clutch - the rubber drive
is not available, and no solutions have been proposed for when it wears out.

Hope this helps.
