...As I mentioned in my original post, I was worried that I may have this issue because I did have trouble getting exact parallel and square cuts. (My main issue was parallel cuts on my rips.) So I have decided to use this opportunity to improve that part of my workflow. This week I received a new pair of Festool Parallel Guides and I am going to use this opportunity (and the wood that I have) to fully calibrate the parallel guide scales and then to make test cuts to ensure I can get parallel cuts at my desired measurement. I will also square off those pieces and ensure I can cut multiple pieces that are all the same size. I am then going to start over with the Sysports.
Because of cutting issues I was ending up having to make the sysports slightly smaller than my original intent anyway so this will give me the opportunity to correct that. And I will consider the initial plywood cost to be educational cost! So, I'll report back when I get to this point again.
Thanks again for the tips.
