Cal table - want one?
« on: September 03, 2018, 05:52:29 PM »
Hi,

FYI I'm sending out some stainless and aluminium to be laser cut and and will add in a cal bed and support to the order. Let me know if you want one. I'm guessing about £60.

Something like this: http://anagram.net/nuts/Versatronics/Cal%20Bed.pdf

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?).

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 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.

Been out of the loop a bit... but after a quick scan I couldn't see a recently updated thread to answer my question.
So, what is the current state of self re-cal?
