BTW the best quote I have atm is ~£7 each in 100-off.

RV Hardware / Anyone want any brass inserts for nozzles?

I'm getting some quotes for these and it seems they need to be made in a big-enough quantity, e.g. 100-off, to be economical. Anyone interested? This is the 'RVT07' design:

RV Hardware / Re: Placing domed 1206 LEDs?

OK ... I ran up a couple of designs - one with a hollow to fit the dome and one with an o-ring (see below). I used the hollow one and as that seemed to work OK-ish I didn't get to use the o-ring one. That worked OK although I had to reset the pick location a couple of times and nudge the finished result around quite a bit. In hindsight I should have locked the pick location as the "pick location adjusting logic" will have been unstable with this shape of nozzle and component. This was all slightly nerve-racking as there were £350 worth and nearly 1,000 of the special IR LEDs on a board :)

For assembly, I'm planning to Araldite the two aluminium pieces together, then drill and tap to M4 and bolt the stainless table on with M4 hex stainless countersunk.

For the 6mm locating dowels on the machine, I'm planning to ream the holes for 8mm OD bushes (actually 10mm OD as 8x6mm bushes don't seem to be available anymore) e.g. item 779-2060PL here:

http://www.wdsltd.co.uk/product/5257/plain-drill-bush-to-din179-standard-wds-779/

If the laser cut location holes are not an exact fit on the locating dowels on the RVS bed, I plan to drill the second hole for the bush slightly larger, mount on the RVS and pick-up the exact position for the second bush and glue in place.

OK sorry for slow update - for anyone interested, I think the easiest way is to put the CAD files here:

http://anagram.net/nuts/Versatronics/cal%20table/

- the dxf file is the one used by the laser or waterjet place for input into their cutting software.

I ordered from alco engineering (e.g. simon@alcoeng.co.uk), and the cost was:

1 off (720.0 x 550.0 cut to shape inc cutouts/holes) x3mm SS304 DP1 £63.51

2 off (400.0 x 305.7 cut to shape inc cutouts/holes) x8mm Aluminium £23.88 = £47.76

plus VAT & delivery.

For future reference FYI this was approx £80 + VAT. Made out of 2x8mm aluminium risers and a 3mm stainless table to give 3/4" :) It'll be properly heavy...

I should say the chance of me starting out on the calibration holy grail any time soon are slim, but I might just get the parts in place for when I get a little more time (maybe 2020?).
