If you’ve got the space, I’d say go for it. I was limited to a 10’ top beam by the size of the workshop I built (which I designed before I came across the maslow)

If you do, remember to get additional chain as the current chains aren’t long enough for a longer beam.

unistrut seems to only come in 10ft pieces (at least at home depot), what would be a good way to make a 12ft beam with it?
You could heat it up to 4000K and take advantage of the thermal expansion?
Seriously though, the only real solution is to take some extra pieces for both ends and bolt them with the 10 foot piece, overlapping for some distance. Maybe have one piece upside down and bolt through the bottoms… but it will have to very tight.
Otherwise, go find an electrical or plumbing house… Grainger or something, because they may have 20 footers
I was going to purchase mild steel square tubing from a steel supplier. This can be as big, thick, and long as you want. I called around, and there is a distributor in town, and the price is ~$50 for a 3"x3" square tube with 1/8" thick wall. After thinking about it a while, I am considering going with something more like 3.5"x1.5"x1/16" thick wall

there are unistrut connectors for end to end splicing. I don’t know how rigid they are, though.
Unistrut is available in 20’ lengths from some suppliers, but the vast majority
only have 10’ lengths
check local plumbing and electrical supply houses (especially the ones that
support commercial contruction)
