Since we are on the theme of pull-up solutions, here is mine:



I thought you boys and girls might like this. The footprint is 4’x6’, it’s 7’2” and adjustable up to about 8’4”. With design modifications via building a second top mount to switch out with the one I have, I might be able to get it up to 9’ or 10’, although I am not sure how much in the way of stability I would sacrifice.

It sits on somewhat uneven ground, and hardly moves when my 230 lb workout partner kips on it.

It breaks down into four pieces and fits in the back of a short bed pickup.

Here is the basic design –

Base – 2 4x4’s 6 feet long attached with two 48” ¾” diameter galvanized steel plumbing pipes using floor flanges.

Each arm – I attached (screw and bolt) two 2x4 1 foot long to the bottom of a 6 foot 4x4, with 3 ½” beyond the end of the 4x4 to attach to the base. Arms attach to the base with a carriage bolt, and I have two braces going off the side of the arms to attach further down the base. To detach the arms, I unscrew the bolt from the base and the top of the two braces.

Top mount – 2 x 4x4 x 1 foot attached with one 48” 1” diameter galvanized steel plumbing pipe using floor flanges screwed into the 4x4s. To attach the top mount to the arms, I attached 2 2x4’s by 4 feet to the top mount 4x4s (glue and bolt) so that 3 feet of each 2x4 hang off the bottom of the top mount 4x4’s. I drilled two holes on each overhanging 2x4 and attach it to the arms with ½ inch carriage bolts. The 8’4” configuration has some space between each arm and top mount 4x4.

Although a permanent station using post holes for the arms would be ideal, this meets my needs.

I’ll post more detailed plans and photos of it disassembled in a week or two.

So far, so good. I look forward to comments and improvements.

That's pretty cool!

It may also be a few clever pegs away from doubling as a portable squat rack.

So, ten bolts to assemble/ remove? I like it.

Hey Charlie that looks pretty cool, just what I need. I'm not figuring out how you adjust for height. Does it involve the 2x4s bolted to the 4x4s?

I am bumping this really old thread because I will be attempting to build the pullup bar in the thread in my backyard. It will be the first step in the nobel tradition of backyard gyms.

I have bought the first four by fours to make the base with the pipes.

I schlepped from the Home Depot in Brooklyn to home. I used the bus. I went when the bus would be empty. I put the pipes in my belt. I looked like a samurai warrior. A woman ran over while i was walking, with ribbon and and a knife and tied the four by fours together for me. I wanted to give her a tip but she refused.

I look forward to having a little party in the backyard when it is finished.

I think for teh rest of the lumber though I'm gonna ask for a lift from someone. I wanted to do it partially on my own just for a taste of something old school.

And this is the reason I hadn't gotten around to making my portable pull-up bars yet. It was fate telling me I hadn't yet found this post. This design is much better and way simpler (which also = cheaper) than what I had in mind.

I'd be interested to know how it stood up over time, but for now, this is a good start

Charley, if you're still around, thank-you

This looks great--just a quick question: about how much did all of the ingredients run?

I was at Homedepot last weekend and priced out the following for a more permanent pullup bar:

2 4x4 8' - $20
2 bags of quickcrete - $8
Pipe - ?? Didn't get to this section, but I can't imagine that pipe and the proper fittings would be more than $15.

I haven't gotten all the parts yet, but this will run me over one hundred bucks I am estimating. It's good. I'm gonna hang rings from it. I'm put it in my backyard, it's gonna be epic.
