I only got the keys to the house yesterday, so moving house will have to take precedent over gym building for the time being, lest I anger the wife. Although I might just be able to sneak away for long enough to grab the plywood on Monday if I'm lucky.
Will probably have to look at building a longer than normal rack since I'll be installing a Rogue RML 690. Not cheap (particularly in Australia) but I figure buy once and buy quality.
