Delta Universal Mobile Base question

[Greg Moore]

Has anybody tried assembling Delta's Universal Mobile Base using regular dimensional lumber ripped to size? I DAGS and couldn't seem to find any examples--which is probably no accident. I'm running a Delta CS with cast-iron extension tables. I'm not specifically opposed to using hardwood, but it doesn't seem necessary with the machine's weight concentrated close to the wheels. I get the impression that the wood frame serves more of an alignment function rather than load-bearing.

Thoughts?

My experience, and advice based on that experience, is to bite the bullet and stock cut to the specified dimensions.

I originally tried using ripped 2 X dimensioned stock ( read 1 1/2" on one face/edge) and it was unsatisfactory. The wooden stock really needs to fit snuggly into the frame to keep it from racking on you in the future.

I ended up gluing tubafours together, ripping them to the specified dimension, and got a much better result.

That said, you may even do better using metal if you have access to a welder.

I've got two machines on these bases with dimensioned lumber frames (leftover premilled mahogany balasters FWIW). The frame racks a little when it's all tightened down, but that's not really an issue. The lift wheel ends up a bit high - I had to stuff a pc of 1/4" ply and a steel mending plate under the cam to make them work like a champ.
