Introduction: No Screws or Holes Pull Up Bar / Door Gym

This is a tutorial on how to make a doorway pull-up bar that does not require holes in any door frames or walls to mount it; which makes it perfect for college dorms or other temporary living quarters. It pushes against the door at two different points when weight is applied to safely wedge itself into the frame without the use of screws or bolts. It has an estimated maximum capacity load of 300 lbs. It allows for wide, regular, close, and hammer-grip pull-ups and chin-ups. Some of the work for this instructable are inspired by Shenandoah of http://www.angelfire.com/ny5/shenandoah/Grunt/Bodyweight.html and other commercial products on the market.

Step 1: Measurements

We need to measure the width and depth of the door to be used. Most door frames will more or less have the same general dimensions, but it is important for weight distribution. Look at the pictures for more details.

Step 2: Materials

Now that we have our measurements, we need our materials:
-3/4" galvanized steel pipe (Length will be determined from door measurements)
-2 x 4-directional coupling
-2 x 3-directional coupling
-2 x 45 degree coupling
-4 x 90 degree coupling
-2 x close nipple (meaning no pipe between threads)
-2 x 3/4" x 3" nipple
-2 x 3/4" x 4" nipple
-2 x 3/4" x 5.5" nipple (Length will be determined from door measurements. This is dependent on the depth of the door.)
-6 x 3/4" x 6" nipple
-duct tape
-sponge
-detachable links
-Pipe wrench
-measuring tape
-pipe insulation
-athletic tape*
-painters tape*
*=optional

NOTE: I could not find any stores that would cut and thread pipe in lengths shorter than 12". That is why I had to purchase individual nipples. If you can find a store or are capable of cutting and threading pipe in small increments, the cost of the project can be cut significantly.

Step 3: Construction

A couple of things to keep in mind before constructing this build is that it takes a lot of leverage to put these pieces together so using baby-oil or WD-40 or some other type of lubricant may be necessary. I also used a longer pipe to use a leverage while constructing the pull up bar, just be careful not to strip the threads.

1) I started with the two 4-way directional pieces. I started by fitting one of the closed nipples to the 4-way directional coupling and then attached a 45 degree coupling to that piece. Make sure to align the 45 degree appropriately. The pictures show better detail. (Picture 3)

2) Then I attached 6" nipples to the 45 degree sections. These will be the wide-grip handles. (Picture 4)

3) I took 3" nipples and attached it to the top of the four-directional couplings. Apply a 3-way directional coupling to the end of the 3" piece so the perpendicular feeder points outwards. Another 6" nipple will be installed here. (Pictures 5 and 6)

4) Then I took two of the 90 degree couplings and attached 5.5" nipples to them. (Pictures 7 and 8)

5) Taking the pieces from the above step I then attached 4" nipples with 90 degree couplings on top. (Picture 9)

6) I attached the pieces made in steps 4-5 to the pieces from steps 1-3. This finishes the majority of the project. (Picture 10)

Step 4: Finishing Touches

1) I put pipe insulation on the two 6" nipples that are positioned parallel with the floor, then wrapped it in duct tape to prevent movement. Masking or painter's tape on top of the duct tape could help with preventing marks on the door frame. I did not choose to do this however. (Picture 1)

2) I took an industrial sponge and ripped it in half. (Picture 2) I shoved the sponge into the 90 degree coupling that will hook onto the door frame lip. (Picture 3) Then I secured it with duct tape. (Picture 4)

3) Then I added the last two 6" nipples to the 4-way coupling to finish off the hammer-grip handles. (Picture 5)

4) You can choose to add athletic tape to the bar to improve grip.

Step 5: Conclusion

This is my first Instructable. I would appreciate any input that anybody has in order to help me improve my future Instructables. My future Instructables will include peripherals for this pull up bar to make it an entire home-gym system. I look forward to contributing more Instructables in the future.

UPDATE: I've included a picture of my pull up bar with athletic tape added for grip and comfort.

    Was your frame 3.5 or 4.5 and does that still allow for clearance in the depth of the frame where about a half inch of the frame comes outward?

    you could also hang a old military duffel bag full of cloths off of it for a punching bag

    Very awesome man. i gota give you props on that. a little expensive compared to the 25 bucks at walmart but i will probably build it anyways just to say i made it. but of course i wont take credit for your ingenuity.

    Thanks for the idea.

    Great instructable! i print it, write down the parts and went to the hardware store... but it was way to expensive to build! (at least here in brazil...), they dont sell small pieces of stell pipe, only the full 236inches piece, for around U$ 60, not nomentioning the joints..., I would spend more than U$100 and still need to pay some one to cut and prepare the pipe pieces, I even tried an alternative, with two sets of a flange bolt attached to the ceeling, with a L curve attached to it, an 3 way joint on the end, with another L curve, but even that would be to expensive... i will need to stick to my old doorframe bar... :-(

    Just put 2 flanges on end of pipes and attach flanges to ferring strip to distribute weight on wall

    This is a great instructable, but I could never trust my construction skills...I'd be afraid I'd fall or rip the trim off of the wall.

    Great instructable. I used this because i have a 42 1/2" doorway and nothing they offer commercially will fit it. Works like a charm.

    Great idea . . . when I get ready to redo my weight room (i.e. start to work out) I plan to build this. What about using semi hard rubber balls cut in half for wall protectors?

    Sounds like a good Idea, but it would probably do something to your wall after a little bit of long term usage. Like a little rounded indent, nothing serious.

    its almost exactly like that iron gym thing there advertising from Argos... yours will probably last longer

    Don't get me wrong, this is an excellent idea (and a not-too-shabby Instructable to boot), but I prefer the sto'bought variety simply because I want somebody I can sue into oblivion should the whole mechanism fail and I find myself on the floor in searing pain. I know, I know, call me picky. :-)

    haha, I completely understand! Falling on the ground is usually not pleasurable at all! :P
