I am recycling some antique fir hardwood flooring. I will convert the
original 3 1/2" tongue and groove 3/4" thick planks into 2 3/4" T&G,
1/2" thick planks. That's the only way I can salvage the original
a) Is there a good alternative to the tonge and groove configuration
for hardwood flooring? (like concealed fastener system and square
b) I'll need to plane down the thickness of the boards. Can I runt the
batch at the maximum possible thickness or do I need to aim at some
industry standard, like 1/2" or 5/8" in order to use a nailer like
porta-nailer, or the like?
Thanks for your comments!
