Straight edge for setting TS wings and extension table.
Ok, I'm close to ordering my new TS (Grizzly G0691) and I'm going to need to be able to get the set up done right. I have a dial indicator and magnetic base so I can set the blade and fence parallel to the miter slots. I have a decent, not great, Rockler square for getting blade at 90 degrees to the table. What I don't have is an accurate straight edge. With the long extension table (saw comes with 50" rip, and I may eventually get longer rails for my Biese fence and use the Griz fence on the contractor saw) I feel I need something to accurately level the saw extensions, and then the extension table.
Question...How long of a straight edge do I realistically need? Is 36" long enough, or do I need 50"? I can get a 36" one from Infinity for 54.95 less 10% discount and probably go ahead and get a blade for my SCMS at the same time to get to the free shipping. I think they still offer that. Or I can get an aluminum 50" Veritas from Lee Valley for about 90.00 shipped. I'm just not sure which length I really need.
Thanks for any insights you can offer! Jim.
