John:
Thanks for readdressing this issue !
Your points all seem well reasoned and I do like the alternate method that you propose.? In fact, while playing with my saw, I was effectively doing just that by placing shims under the engineers square until the blade just skimmed the square the whole distance.? I do agree that actually cutting, and averaging multiple cuts makes a lot of sense.
There is a certain risk in cutting because it is quite possible for a blade to not cut straight because of worn / damaged teeth so perhaps it is best to use a new blade when doing this procedure.? I do have a new blade, and I will also compare methods as a cross check...? It goes along with the old adage - Measure twice, cut once !
I did this pretty quickly, and plan to spend more time being meticulous, but it looked like my pivot was off by about 0.062" (a 1/16" shim under the square was very close).? It was visually obvious as soon as I moved the arm with the square in place.? If this turns out to be correct, I am curious where it falls in the spectrum of these machines.? I do have a metal lathe, and will probably make a new shaft using the lathe when the time comes.? I am not sure how old this one is (the G1010 is no longer produced) but it is in very good condition.
Finally, do you have an opinion about grease vs. oil in the gearbox?? The Grizzly manual specifies grease.? I did see a post in this forum (maybe yours) about a wide variety of different oils.? I am tempted to follow Grizzly's instructions in the manual.? It seems to me that you would design the gearbox differently for oil vs. grease.? I am just a home hobbyist, so the saw will be used infrequently.
-Thanks
?Tom
