I also need to trench something in to provide power feeds for a couple
of centrally located machines. Any suggestions on how best to cable
this? Trench with lid, or just bury a pipe with a drawrope and leave a
big open access box at each end?

It'd be much easier to run the cable round the walls and across the roof and
then down than go digging holes for it. You don't bollox an otherwise good
floor just to get power feeds in to machines which may want to move at a
later date anyway.

Quite!

Also, you may need extract ducting for dust and chips. Route the cable
the same way. Benches, morticer, pull over saw, drill press can all
stand near the walls anyway.

How are you going to keep the chill off?
