A board (12"x36"x3/4")
2x4 (~ 10')
Right-angle brackets (x2)
A steel pipe (36" x 1")
1" flanges (x2)
Screws (lots, various sizes)
Step 1: Planning and Design
I decided that I didn't need a lot of redundant holds, and I didn't want a cluttered design, so I laid out an arrangement which provided some spaced jugs low down, some narrow jugs high up, and finger boards of three sizes. I also laid out space for round and flat slopers, although in the end I only added flat slopers. I also thought to add some cutouts.
The installation space I chose is a passageway between my bedroom and the bathroom. Most designs suggest finding studs and then attaching the board to them. This is fine, except I rent and wanted to avoid drilling holes into wall beams (or using a stud finder), so I picked a place where I could rest the weight on doorframes. Note that the board is not resting on molding, which cannot support the weight.
Step 2: Cutting the Backboard
Step 3: Making Holds
In the third picture, you can see a 2x4 which I cut corners out of and sanded down. This was a change to the original design because the wood was bowing during early testing. Again, consider 1" wood if possible. Overall, the 2x4 came out much better than the original design, although it required the use of a band saw, which I didn't own.
Step 4: Putting Together the Hangboard
If you wanted to, you could do a lot with just cutouts.
Step 5: Installing the Hangboard
You can buy a chin-up bar easily. I used the pipe because with the flanges, it was about $18, and it saved me a trip to Target or a sports store.
