news:m1y0yfr11p.fsf@void.com...Thanks everyone for all tips.
One is, given saw cutting long lengths of "box" is accurate transversely
but less so "vertically" due to spring in section and distance outrigger
is from saw, position "flash" at "side" as sawn so have "square" end
as do "measure along" direction AND drill can go through both sides of
"box" on drill-press, not risking hitting "flash" on opposite side.
I will look if adjustable square with a wide "foot" is available. Would
need a "foot" about 2inches / 50mm wide for when doing big Rectangular
Hollow Sections with big corner radii.
Bigger overall point - thanks a lot everyone.

You could make a wider foot from flat stock clamped to the square with screws and large washers cut D shaped.
My procedure for cutting short sections from long lengths is to first balance them on the bandsaw table, then place a Toyota Land Cruiser telescoping screw jack under the end. When the stock is moved to cut the support will nearly balance it and the vertical force at the saw vise will be minimal. If I had two finely adjustable supports the second would go under the end to be cut off and I would sight down the stock to lift out any sag.
I work on uneven surfaces outdoors and can't permanently set up an outrigger, plus the roller stands and conveyer table I have are for a wood saw and don't adjust low enough. The bandsaw had larger wheels added to roll to the job, which may be on a dirt path in the forest. It's a 4"x6" which is light enough to move if not the best to use.
The one time I had to cut full mill lengths of 4" square tube and a W10x33 beam (W250x49) I used the hydraulic platform stacker to lift and level it on the saw table.
