that's the beauty of this whole design is the speed in set-up & then removing the LS positioner from the table all the while of being absolutely Square with no need to adjust anything to be square .
I was working on building my own design but was hung up on getting a absolute square jig outta my own limited tooling in my shop .
I had gotten the all materials I needed & was proceeding forward but when this hit , I added up all $$$ I had in material costs , this plate was near that figure .
with any mistake or slight flaw in my design that would have put me over in costs of materials & some AL plate stock with holes in it
I couldn't use .
the materials I have can now be re-purposed but couldn't be used IF I had flawed in any way .
I got a shipping notice a hour after I ordered , I should have it in hand tomorrow
as they ship from La La Land
