Hello,
TL;DR (too long, don't read): if I try to take too small of a pass on a table saw to joint an edge, can the blade deflect instead of establishing a straight edge?
Longer story:
I undertook a project with my brother over the weekend. We're attempting a table as shown below. 2" thick out of maple/cherry/maple. We were perhaps in over our heads. We glued up three individual pieces (about 62x11x2" each) and ran them through my planer. Unfortunately the final glue-up of the three 62x11x2" pieces didn't go well. We started with gluing two of the 11" pieces. Unclamped after only an hour (yeah, that was a mistake) and a crack immediately appeared. So I ripped them apart on the table saw.
During the process I lost (or never had) a straight edge. So now I need to re-establish a straight edge on 2 of the 62x11x2 inch pieces. And it is simply too much to handle on my 6" jointer that has a relatively short bed. My little jointer had no problem with the individual pieces of wood, but not the glued up sections.
It seems the table saw is my best option for re-establishing straight edges. Well I tried that, it still didn't end up with a straight edge. Either that or the blade deflected (?). Thus I may have to use a table-saw jointing jig (?) since I'm not sure any of the edges are perfectly flat. Either that or the crappy fence on my Ridgid R4512 deflected (I have a Delta T3 replacement on order). Yes, I need to find a long 62" piece of flat wood to establish as a straight line reference and determine if I can just use the fence to rip a straight edge on the other side.
But since I'm trying to avoid removing too much material, I'm wondering if the blade will deflect rather than create a straight edge?
Thanks
p.s. Not only did I botch the glue-up, but I also botched the cost estimate of the project. The intended table size is 60x36x2, which is 30 board feet. We bought 52 board feet of wood thinking there would be plenty left over. We barely, and just barely, had enough wood which I find kind of shocking. That is after cutting/jointing/planing about 50 individual pieces. And...since I'm a newbie, I thought that a board-foot of wood was a square foot thing and not a volume thing. Hence I underestimated cost by...half! Sigh.
