Thanks Murre. I've made some clamps, no need to worry about sending some, but thanks for thinking about it.

It's a vintage Buma machine, probably from the 1930s or 40s.

Understand re the lip for the sleeve.

Lets say I'm going from 30 thou to 60 thou, would you expect that to be done in one step or two?

Is there a minimum cut you can take? Or is it difficult to cut a very small amount and hard to arrive at a size. If using two steps to arrive at a size should the two steps be even? or in this case say go to +50 then ten more to +60?

I suppose it is very much a case of learning the individual machine.

Thanks for the help.

Mart.
