Need a flat 22mm open end wrench for a Grizzly 1023 SLW table saw, i. e. a flat wrench with 22mm jaw. Having read about a disaster when a blade came off an arbor, cinched mine down well. The wrench furnished with the table saw bent rather badly, because perhaps it's either made of mild steel or I tightened more than I thought [appropriately giving Grizzly benefit of doubt...it was probably me though].
Regardless of the cause, I would like to find a stronger flat wrench that is perhaps heat treated. I bent mine back into shape twice, and bent again both times. If a replacement is ordered (rather costly for just a wrench) the same problem could well occur. An alternative would be to purchase an open end wrench and grind it flat, or fab one from flat stock, which I could do but not heat treat, which is probably needed for strength, perhaps not done with the original tool.
Any ideas....or known source for a stronger wrench? I am making a spice rack for daughter, and might be between a rock and a hard place if I don't figure this out. Such a simple problem...aren't they all though.
