3D Printed Quorn Tool & Cutter Grinder
nrml:
The best looking way to do bellows would be the origami method used by the vintage camera folk. Use polyester paper. It should fold like paper but won't get torn as easily.

There are places that will make them for you - I had some made for my Fanuc Tapecut Wire EDM re-build.
These are simple 'curtains' but they make all sorts of complex shapes. I would have made them but getting the right material proved the problem so forked out a few pennies

Do I give you the credit for coining the term? I love it!

That you would do yes. I really dislike 3D printers in its current "form".. They can rarely print something that is really useful, even on an industrial scale.. But for casting molds, matchplates and prototypes i think they are in their right element.

Next parts coming off the CAD system. It's been FUN, checking the geometry and as far as I can tell I can still move a cutter into the same plane as the offset head, just not as far off centre. Will it affect relief angles ?
I really wasn't happy with the idea of going with a single side support, though it is in another drawing revision if I want to try it later. Moving the head inboard also meant having to sculpt out some of the casting to allow the head a full ±30 degree movement.
I have increased the rotary table spindle diameter to 15mm, this is one area I am unsure if I will need a metal component to support the table above it.
The scale will be printed as a seperate component in black to be treated as the thimble was, then welded in place. Still to sort, the pointer arrangement coming off the table support, nothing pretty yet and may stay that way.

I suspect that over time the parallel bars, if plastic, will sag. I hope that I am proved wrong, but that is what my engineering experience predicts.
