I am putting a pool table in my living room and it will weight close to a 1000lbs. I was going to sister plywood strips to the existing joists to strengthen them. I had a bunch of 1/2 inch sheets left over. However everything I read suggest 3/4. Do I necessary need to put down 3/4 or can I get away with 1/2? I have seen too that they put two layers of 3/4 up to make an 1 1/2" to match the existing joist. I thought of just putting three layers of 1/2 (making it 1 1/2) in since I have a bunch of sheets leftover. Can someone tell me if this doesn't make sense structurally? Otherwise it's a easy way to save some money.
Thanks
