I've some bits to cut tomorrow that don't require absolute precision so ill surface the bed and then think about it.

There was a thread where someone used Alum to dissolve the tap...trouble is I'd need a big pan to simmer the bed in!!!

Ultimately it won't matter as I'll be doing the T slotted base thingy...but it's still annoying!
