Rolling stand
Over the last few months (almost a year) I've been doing a job for Bob (China). He managed to get hold of a pair of jewellery rolls; could I make up a frame for them?
Today I managed to do the last of the tricky bits, so here it is.

The gears on the top are to synchronise the two screws that push the rolls down.
The rolls themselves are synchronised with the two gears in the photo below. M5 - probably the largest tooth size I've ever cut. They go on the two stub shafts in the photo and then the cover at the back goes on (this thing will be motor driven, so no chances with mashing a finger)

A little bit of tweaking to go but substantially done. Most of the steel is reclaimed from some injection moulding dies that a neighbour gave me a year or so back, so there are a few holes here and there that make no sense but there is a reason for that.

Hi Michael,
That looks like a work of art. Very solid. Nice work.
Excuse my ignorance but what does it do?

I just make them...
From what I was told, precious metal is cast or supplied as wire. These rolls are to reduce it down to a desired size. The grooves in the ends of the rolls allow the wire to be shaped to a D or other shape if it is there.
My estimate for what is there is just north of 50kg, so yes, solid.

That is coming along nicely Michael, another twenty kilo's for the motor and gearbox, for those who asked have a look here it gives the basic understanding of what it is used for

Added the depth indicator today. Using a feeler gauge, it even seems to be 'accurate'.
