Thanks for trying to reproduce my experiment Jeff. After reading your reply I re-checked my theory on my own machine and no hum. Now I'm really confused why it ever hummed in the first place. It could have been the lamp, but it was definitely a noise coming from the motor.

I'm really liking this forum - not many forums have this kind of involvement from the members.

Myth Busted!

Agreed.

I agree Jeff - it is weird. Do you have a large magnet you can put on yours to try to reproduce the issue? If you do, put it on the  nameplate sticker on the front.

I've only had my T7 for a week or two, and at first it ran very quiet, but this past weekend I was working late into the night in my poorly lit garage and it was making a loud hum. I thought that was weird since it is so new. I gave up soon after and went to bed. The next morning I came back out and went to work again - this time, since it was day, I removed the magnet base lamp I had stuck to the T7 body the night before. The machine was once again whisper quiet! Magnet lamp on the T7 - loud. Magnet lamp taken off the T7 - quiet!

Looks like the magnet at the base of the lamp was powerful enough to interfere with the magnetic field inside the motor. Lesson learned.

Now, I just have to find (or make) a lamp with a post base that fits into one of the fitting holes on my T7. I'll keep you updated.

Hi Rick, I also noticed this to some degree on my jointer knives. I think I was pausing longer at the end of each stroke and kind of zooming through the middle section. I adjusted that by slowing down toward the center and spending less time on the edges.

I also had my first experience recently with using the Planer jig, though I used it for 6" jointer knives. Did it take a long time? Yeah, sort of. I can blame myself for much of that because I waited far too long to sharpen them and they were pretty uneven. I fully expect the next sharpening to be much quicker (as long as I don't ignore them again for too long).

As for setup and use of the jig, once you read the pamphlet and understand the concepts, it all just kind of falls into place. I think next time I will be able to do the setup without resorting to the manual - it's that straightforward.

One complaint I do have is that the AngleMaster doesn't work unless the knives are pretty wide. I have Freud knives that are 5/8" wide (standard for my jointer) and the AngleMaster was useless on them. That is something I think could be improved upon.
