So I received a poorly made saw arbor from McMaster. After reporting this to McMaster, they sent me another SA-1000 arbor. It has the same problem! The screw hole in the arbor is not in the center. The first arbor screw hole had a TIR of 0.036". I haven't yet measured the second arbor. Just like in the first arbor, the second arbor's SHCS jams against the counterbore of the arbor cap. This causes the arbor cap to no longer to be square to the arbor critical surface.
I don't want to keep bothering McMaster, when it is Sierra American's quality problem. McMaster sent me this replacement arbor at no charge. I received the replacement in one day! Too bad it is not a good part.
I'd like companies like Sierra American to survive, but they won't if they continue to ship junk. I think I will end up contacting them to complain. I know I can fix this by boring a hole in the right place and putting in a larger screw, but I shouldn't have to, especially a product that is selling for over $50. The second arbor as received did not have the screw seated fully. It couldn't be seated, because it was jammed against the counterbore. I would think the screw should go freely in until the cap is firmly seated against the arbor. Is it possible this is a valid design element? I did measure the TIR of the saw mating surface on the first arbor, and it meets the product specification.
Don't know what my approach will be with Sierra American. For that matter, don't know what to say to McMaster. I'm not mad at McMaster. It's not good for McMaster to stock crap product. Have to say, I am disappointed with Sierra American.
Anyone have some insightful feedback? What would you do?
