Get a 4’ length and 2 x 1’. Fittings: 2 x 90 degree, 2 x threaded flange. Bolt the flanges to the 2x4.
.
I’m thinking I could just install the mounting 2x4 on top and across the two joists, mount the flange to it with bolts, then run the 1’ pipes towards the ground, connected with 90s. Make sense?
Connect the mounting 2x4 to the tops of the joists when everything is in place with wood screws, and possibly small blocks on the sides to hold in place.

That is exactly what I have been considering. I did the same thing with bike hooks. That way the load is spread across 4-5 floor joists. I will probably do the same. If you build yours before me, put up some pics. I am obsessed with pullups right now…
