Can a 5"x1 3/4" joist support a WM18
awemawson:
When I unloaded my Bridgeport at my last place, I reversed the trailer into the workshop and erected Acrow Props either side of the trailer pressing up onto the relevant joist above thus minimising the span of the beam.
OK they were 9" x 2" joists but the span without the acrow props would have been 20 foot !

You could also connect the rafter to the joist halving the load .

You could also put in beam running across several joists to spread the load.

Thanks to all for the ideas.
Acrows sound wonderful, never thought of using them like that. I have some 3" box section which I can place in between the beam and the acrows, that way the stress is taken by the acrows and steel box section with the joist just giving lateral stability with minimal load on it. Acrows look like they are good for a ton so it should be comfortably rated.
I'm also considering making a stand for it with castors on to simplify relocation if needed for cleaning, maintenance etc. Is this a bad idea with a mill?
Best Regards

Just make sure that the joist and box section cannot pivot forward or back by having them fixed to several other joists by a tie timber. In my case there was an OSB floor above fixed to all the joists very effectively anchoring the one I was using.
