Chin-ups are a good exercise to build upper arm and chest strength. One of the advantageous things about chin-ups is they can be done anywhere. If you would like to do chin-ups in your house, its possible to build a chin-up bar that can be hung on a door and doesn't have to be physically attached. This way, you can do your work out at home and you can easily remove the apparatus when done.
Step 1
Attach an "L" bracket to both sides of a 4-inch piece of 3/4-inch steel pipe. Wrap one of the ends of the "L" bracket in duct tape. This is the side which will hang on the door. Repeat this for the other 4-inch piece.
Step 2
Attach 5-inch pieces of 3/4-inch steel pipe to the "L" brackets that don't have duct tape on them. You should now have two "L" shaped pieces of pipe.
Step 3
Fasten a "T" bracket to the ends of both of the 5-inch pieces, The bottom part of the "T" should be facing the side of the "L."
Step 4
Place 6-inch pieces of 3/4-inch steel pipe inside of the bottom of the "T" brackets. These pieces should stand straight out from the "L" you created. Cover each of these pieces with pipe insulation.
Step 5
Add a 3-inch piece of 3/4-inch steel pipe to the remaining openings in the "T" brackets. These should form a straight line with the 5-inch pieces.
Step 6
Attach a "T" brackets to the end of the 3-inch piece. The bottom of the "T" should be attached to the 3-inch piece with the other openings out to either side.
Step 7
Attach the two pieces you constructed by screwing one of the open end of the "T" joint you placed into either end of the 24-inch piece of 3/4-inch steel pipe. The other open end of the "T" should be facing in the same direction of the insulated 6-inch pieces.
Step 8
Place nipples inside the open side of the "T" joints. Attach the 45-degree brackets to the nipples.
Step 9
Fasten the remaining two 6-inch pieces to the 45-degree angled brackets.
Tips and Warnings
- This design is for a standard door frame, but should you wish to hang this on a different sized door, make adjustments to the sizes.
- Make sure that all pieces are square. The strength comes from the pipes opposing each other. If all the angles are not square, the bar may not be stable.
