« Part 1: Working on the design, getting the parts. Part 2 of Dave's Wide Drum Sander Build. series Part 3: Sources for the parts. »

The VXB 5/8” shaft pillow block bearings are in, and upon unpacking them, I made a bad discovery, the bearings are in the pillow blocks, but they are very poorly pressed in, meaning they are pressed in at a funny angle, not square to the faces.

Since the safety / emissions inspection on my Saturn is expired, and I need to go to the shop for that anyway, I figure I could possibly impose upon the mechanic to use his shop press to drive these things home properly while I am there, we’ll see…

Overall the castings seem to be first rate, much better than I had anticipated. The grease zerks are cleanly fitted, and everything other than the press angle of the bearings seems ready to go…

The storm fall limbs I was expecting to use have too many fractures. Tonight I clean up a piece of old waterbed side rail (Red Oak) slice it up, and glue it up to make my blanks.

Now this is feeling like good progress…

I hope the castings don’t fracture when you press them up.I guess this is a friday night job but I bought one of these type of bearings when I took my new saw apart to get it into my woodshop the old one broke my young sons fault.I replaced it easily enough have fun Alistair

I hope that you can get your Bearings Straight, both literally & figuratively. Sounds like you are ready to Beat the Drum on this build!
I know, I’m a punny guy! It’s not a character flaw….it’s a LACK of character flaw.

Do you get the feeling that you are being followed? You should, I’ve put this on my watch list.

Good luck with the build.

You likely have pillow blocks that allow the bearing to swivel to align them self in case the blocks are not installed in line.

I’m watching you. We, my son and I, have just started to build a drum sander. The drum is ready: 32” metal drum. Soon as I work out how, I’ll post some pictures.

I noticed the same thing with mind, at first glance! But then I realized, on mine, it was an optical illusion. The housing was more narrow at the top than near the bolt mounting portion. This made it look “off”. Hopefully that’s all you are experiencing.

Don’t go pressing on those bearings! They are likely spherical outer race, self aligning pillow blocks. The housing bores will have two interruptions 180 degrees apart for insertion and removal of the bearings. They will self-align when installed in the machine.

Now that I look closer at the photo, there is no likely about it! Those are self aligning.
the spherical housing interruptions are clearly visible.
