Hello

I would carry the sisters to the end.

Customer: replied 1 year ago.
if I had 2x12x20 sister to the existing 2x10x20, with bolts and glue with no plywood, am I still on shaky ground and in the mode of "keep it light", or am I making it pretty solid? What else can I do to make it very solid? Put sisters on both sides?
Expert:  StructuralEng replied 1 year ago.

That's good for a single floor, no more. No ceramic tile, though.

Would that be strong enough for a large printer weighing about 350lbs?

What footprint?

Customer: replied 1 year ago.
The span of the joists in the garage are 20', but only 11' of that planned to be finished, pretty much in the center of that span. The width of the planned room is about 20 as well.

How big is the printer base?
