How can I build a board to mount climbing holds in my house?
I want to screw a board in my house to mount indoor climbing holds, like an indoor wall. so a piece of board with evenly spaced screw holes in it that accept the standard screw mounts for climbing holds. something like this:
Problem is I don't know how to do this? Multiple questions:
- What type of board?
- How do I get the screw holes in (what the holds screw into)?
- What size bolts/screws do I need?
I'm happy mounting the board, that's the easy bit. It's actually building the board itself I'm stuck on.

You will need to counter sink (fostner) the nut (bottom right) on the back side (because it will be up against the wall). A drill press would be nice. Or space the board from the wall. Any solid wood thick enough. If you are not going to counter sink then you should be able to use plywood. Practice on a short section.

Typically, using 3/4" (19mm) plywood board is strong enough for this use. And the bolts you want are 3/4" (19mm) plus enough each end to screw into the hold and to accept a nut.
Bolts used for most holds are M10 or M9.5, so check which your hold supplier uses, and then make sure the holes you drill are that thickness. This sort of bolt seems to be the most common in metric countries.
Don't use more than 2 holes per square foot (21.5 holes per m2) of wall surface (think the industry standard is 2.25 but err on the safe side)
Tightening them up doesn't require anything clever - no countersinking required, just tighten them right up. I wouldn't mount it flush to the wall anyway - you are better off leaving that gap so you can get at the bolts as needed, rather than remove the entire piece.
If covering an entire wall, fix the climbing wall to all your studs, not just at each end, in order to avoid the board pulling away in the centre.
