    At last, structural alterations finished to workshop, what a damn mess it makes cutting a doorway through double skin concrete blocks. I've also rearranged the shed layout and there's room for everything now.
    Frame now painted and rail bearing beams mounted. The shims worked okay but if you imagine the Forth Rail Bridge it's a bit like that where the 'humps' are in the gaps between the bolted flanges. Of course when I say humps I'm talking about 0.2mm. Now that's not so bad, but, and it's been said before by others, looking at the ends of the beams they are leaning very slightly out which means the rails and hence linear bearings are also going to lean out. To get things moving I have therefore decided to epoxy the top surface and to just for diversity (and cost) can anyone see a product here Polyester - Standard, Silicone Rubber items in MB-Fibreglass store on eBay! that might fit the bill, I think I need 2 to 3mm max thickness.

    Also more news on the issue with ABB drive + Elte spindle, soon.

    Sounds like a persuader is called for...and if the small one doesn't work then get the big one out :)

    That only works for fitters so I'm thinking about wedging a few screwdrivers in

    I know but it's one of those times when I feel an equivalent can be found at much lower cost, I'll think about it today.
