« Part 1: The Table Saw Adventure Part 2 of Shop series no next part

In the last “Table Saw Adventure” entry, I mentioned a major wobble in the arbor. While my original thinking had me polishing brass screws, that did not turn out to be the solution. I assumed these little guys;

were the responsible party. I thought they had come away from the motor/arbor mounting plate and had caused the bearings inside the arbor assembly to not be seated properly. You can see the set up here.

I got the brass polished till it shined, set the screws snug against the mounting plate and found out that tightening these simply locks the arbor assembly against the mounting plate.

After more head scratching and studying the exploded view diagram in the manual, I hit the solution. The rear bearing seen here

From Table Saw Adventure
has something called a “wave washer” behind it, or at least it is supposed to. It either disintegrated, got fused to the aluminum bearing housing, or they forgot to put one in. This wave washer keep forward pressure on the bearing keeping the whole thing snug.

If you’re ever bored, call up a few home centers and ask the guy in hardware if they stock wave washers. 10 to 1 odds he’ll transfer you to the “home appliances” department in an attempt to sell you a washing machine. Out of sheer frustration, I started searching my “various parts and other junk” cabinet. Since I keep everything that looks like it might be useful someday, I found something that looked like it might have worked. So, with a hope and a prayer, I threw my newly found “wave washer look alike” into the bearing housing using a little “White Lighting” to keep it in place while I inserted the arbor housing back in place. I wiggled the arbor . . . no wiggle; I spun the arbor by hand . . . no funny sounds and it spun easily. While I did have that moment when alarm bells start going off in my head . . . you know the ones, “dude, you’re gonna flip the switch and the whole assembly is just gonna blow apart, scattering shrapnel all over you and the shop . . . you’re gonna die, fool!”, I decided to close my eyes, hold my breath, duck down behind a chunk of plywood and hit the switch. The first try, I flipped it on and off rather quickly. I didn’t hear any funny sounds. In fact, the saw never sounded so good. At this point I couldn’t wait to cut my first piece of wood on the saw.

Well, this turned out to be a longer entry than I wanted, but I did reassemble the whole saw before cutting that first piece. There was no way around it. While I was scouring the internet trying to find a solution for my vibrating arbor, I saw some aforementioned bad reviews of this saw and at least one guy mentioned that you can’t adjust the miter slots to the blade. I found this to be preposterous. In fact, The Woodwhisperer video gave me some clues. I got pictures too. I’ll have to put those in another blog entry because my wrists are going numb from all of this strenuous typing. :)

That’s quite a FIX!

Just think… you possibly saved the cost of a New Saw! :)
