Thanks for all the responses. This has been very informative!
I've only been able to get into the shop for a few mins this week. However, I borrowed a friend's Bora straight edge ripping clamps. They were a bit frustrating to setup at first, and I didnít have high hopes, but they worked pretty well!
I ripped two boards on 1 edge on then placed them together. No gap! Below is a pic.
After reading the comments from everyone, I think the issue is my jointer. When I put the Bora clamps on the jointed edges, both of the boards had small variances near the middle of the boards, which would explain why the table saw wasnít lining up correctly.
Now that all indications are that I finally have a straight edge, Iím going to run a board thru the table saw tonight to straighten up the other side and then see how square the board comes out.
This table table is going to be 7ft long, so I'm hoping this is my last straight edge hurdle!
Again, really appreciate all the help on this.
