Mounting a pull up bar on a bumpy wall

Submitted by Toitonic t3_z1ti0m in DIY

Hi all,

I want to mount a pull-up bar like in the picture I linked below to a sturdy and even wall. Unfortunately it is very old and it's surface is somewhat bumpy. That means that when I just mount the bar as is, not every screw hole will touch the wall which in turn will lead to an uneven distribution of force and that 'creaking' metal sound when I do pull ups.

Does anyone have ideas or experience on how to circumvent this and make for quiet pull-ups? My neighbors will love your ideas ;)

Edit for anyone stumbling on this: using wood shims like the comments suggested worked like a charm for me.

Use a wooden board in between

100% this. Get a 2x6 or 2x8, mount it to the wall, then mount the brackets to the board.

You can paint it before to match the wall color.

You want to shim the mounting bracket under an mounting screw holes where it is not touching the wall. You can use regular wood shims available at any hardware store. You will want to drill to drill a pilot hole through the shim and stud to stop it from splitting. Use a utility blade (always cut away from yourself) to score the and snap off shim when done.

Thank you for the good advice. I will try it out and hopefully thank you again when it is mounted and working.

I mount machinery to walls- similar situation. We drill the mounting holes, insert the anchors and then use Devcon Plastic Steel as a bedding compound to evenly distribute force. For something like a pullup bar, PL Premium or Premium Max also makes an excellent bedding compound and has the compressive strength, workability and ease of application you want.

The old fashioned solution is Rockite- it's used for bedding machine tools but it's not perfectly waterproof.
