Etch Press Build

[Wal]

Hi all,

Just wondering if anyone has any experience with building an etch press - something along the lines of this:



I've started to design one and have begun collecting odds and sods that I'll be using along the way (take-up bearings, flange bearings etc.)

One thing that's got me a bit stumped, though, is how to get my hands on a pair of live shaft stainless rollers. I'm attaching a .pdf of what it is I'm after. Dimensions are approximate at the moment, but won't be far off that. The long 60mm shaft will need a flat on it for the hand-wheel grub-screw to bite on.



Ok, there's the obvious way, pay someone to turn 'em - I imagine this will be pretty pricey, given the chunkiness of what I'm after, but if you know any different then let me know..!

Or I could fabricate 'em from a steel pipe with a steel shaft passing through it held central by a couple of alu caps made on the mini-mill. (All probably glued up with the strongest epoxy I can find...)

Any other ideas..?

Wal.
