Ahhh those door frame ones seem too fragile, but whatever works!
Mine is Simple yet Rugged:
Simple. Two long boards that can reach your ceiling (of your basement)- secure them to the rafters and secure them to a board laying on the floor. Drill some *****in' holes (preferably level with each other) and slide a 1 inch pipe through- use the pipe closers (the ones that screw on) to secure the bar. If the holes are just big enough for the pipe, there will be friction and the things not gonna move on you. If it does move, either: A) Suck it up or B) put stuff in the holes to secure it.
Got a black marker hanging from the end of a tube and everytime I do a set I write the number of p-ups on the board. Its cool seeing your progression and the shear amount you've done. Also put some motivational stuff on there too.
