The interlock was wired to the wall today with the new plug; it still needs some sealant put on the estop before it’s mounted to the table due to the gland being busted, or a different button that’s better sealed. I didn’t want to drill mounting holes in the legs until we figure it out for sure.
In the time since the grinders were moved one of the wheels was already loaded with aluminium. I got it dressed enough to ring and not have the visible veins, but the wheel needs to be replaced.
The wheels from MSC’s plastic bushings don’t conform well to our motor shafts either. The Sait wheels fit very well with theirs. On the left grinder with one of the new wheels there was enough slop in the wheel it’s likely contributing to that unit vibrating more. Is there a reason we switched? We could probably resolve the bushing issue but unless there’s a reason for those specific wheels it seems like effort for an unnecessary change. If we’re going to stick with those wheels we should get a different dressing tool as it seems they are slightly wider than the others in tolerance. The tool we have was already tight on the Sait wheels.
This grinder table also resonates like a beast. Even with the motor off as it winds down the whole table resonates and you can hear it increasing and decreasing periodically with the wheel speed changes; one of the legs bolts rattled off level just testing things out.
It’s going to need some serious vibration dampening. The grinders should also probably be unbolted from the table, or should have the holding force reduced. They’re large enough if you’re using enough force to push the grinder it’s too much. Typically bolting these 8 inch units is meant for pedestal use. The compression reduces the efficacy of the existing vibration pads on the rubber feet. We didn’t have this level of vibration on the old grinder tables.
