"magnet just barely sticks to it"


any sort of attraction at all means it is ferous. brass or bronze will not have any attraction. touch it with a dremel grinder, sparks will tell ya.

I'm with the others more hassle than worth. just buy one.

According to Wikipedia (famous last words), aluminum bronze and manganese bronze both contain iron.

I'm guessing you wouldn't notice any attraction with your typical refrigerator magnet, but with a high-powered neodymium magnet I've noticed attraction to a lot of things I wouldn't have thought to be magnetic.

I'll see what I can find out for replacement part cost from the usual sources.

Well at least they did the sensible thing and made the gear out of soft material and the shaft out of hard material!

sparky961:
Update: I received a reply from Busy Bee in regards to this, and they said this gear looks like their part number P192991 at a cost of $44.95 each.

Ordinarily, I'd agree that the time spent making such a mass-produced part is not time well spent, but when I picked up this saw it was my intention to put it back together piece by piece making every part I could.  So, that's what I'm planning to do at this point.  I found someone with a small chunk of "wear-resistant" bronze (no idea what the alloy is), and I'm going to see what I can do with it.

I'll try to come up with some photos as things progress.

jim:
i understand what you mean about making the parts you need.


i'm quite sure all of us waste a bit of time making stuff we could buy.

sure would be a good project
