7' X 4' Combi

Hi Jazz did you make your slots, if so how or did you buy the plate somewhere if so where

He used aluminium flat bar, so the strips span the width of the bed with a small gap (12mm ish?) between each strip so you can put a bolt through and use nuts/T-nuts or whatever underneath the bed. Can also skim the strips several times without problems. I went for a single sheet to better contain flood coolant and I'm going to add strips on top to make T-slots.

If i were to go for a solid plate that size at 20mm thick i would be looking for someone else to drill and tap all the holes as I wouldnt look forward to that

50p per hole ;)?

Drilling them is easy if you use the router with a carbide drill - it's tapping that's the tedious bit.
