I think it will work well for you. The price difference between 1/2 inch and 3/4 inch ply wa only $5 so I went with the 3/4. But I don't move mine around.
I used 1/2 in everywhere. It's plenty strong, but if u had to do it over I would have used 3/4 on the top.
The plans for version II call for 1/2 inch all around.How 'bout expanding your reasoning 3/4 wise. I just ordered the plans as well. Thanks, Joe
You have to beef up underneath the top for the tracks.I think it looks like a great bench. The plans for 1/2 inch top have me wondering about cutting the dados for the t track and mitre slots. It doesn't seem there would be much left to support it compared to 3/4"
