This is korrekt. As long as you drill your holes straight and pound the t-nuts nice and flush you shouldn't have any need for liquid nails....and because you did such a nice job with those t-nuts you'll never need to get behind the wall. That'll mean you can fill in the right side as suggested by others.

I must say an ounce of prevention is worth a pound of cure...when you get bored and start resetting your holds you may wish you had considered it because when the tee nuts drop down the back that ply wood is a pain to remove (heavy). T-ntus do get stripped....well the wood does from the occasional (hold) spinner or from becoming skewed when hammering. This advice is coming from actual experience of building a huge gym in my garage. Take it or leave it..just trying to help you out.

Which is exactly why I said to make sure holes are drilled straight and t-nuts pounded nice and flush. I've built 4 woodies (the latest being almost 400 sq. feet) with thousands of t-nuts and have had only a handful of spinners. My and rockforlife's point is that if done correctly liquid nails isn't necessary.

no they don't

Not at all, I can get them up today, without holds, or tommarrow night, which holds on the wall. Its up to you, but is there anything specific that you wanna see?

Did you take the plywood down to hammer the T nuts? They really need to be on a solid surface so you can get good contact. If the ply is still up go behind.. draw pencil marks where the framing is so you don't put a useless t nut there.
