« Part 1: Cleaning up the bed Part 2 of Jointer clean-up series Part 3: Completion! »

I began removing individual components of the jointer. The paint on the jointer looks to be in good shape though I’m a bit concerned about it having lead content (call me paranoid). The biggest hurdle at this point has to do with the shaft of the cutterhead. The keyway is worn and the pulley and shaft have a huge gap so it’s not clear to me whether or not the pulley bore was made bigger somehow or if the shaft was turned down.

Here are shots of the worn keyway on the shaft:


Here’s the pulley:

This shot shows the gap:

At this point, I’m a little confused about this jointer because it seems it’s a bit of a misfit. According to owwm.com, the bearing housings should either have different part numbers (ending in 0001 and 0002) or should have the same part numbers (ending in 0003). My bearing housings have the same part number with both ending in 0002. I was hoping to use that to determine whether I had a “newer” jointer or the “early model” which would dictate what the cutterhead shaft size is supposed to be. I seem to have lost my calipers so I can’t take accurate measurements but based on my crude measurement, it would seem as though the shaft is 9/16” (which would be a newer model). But there’s also a bit of a taper that can be seen in the shaft so maybe it was 5/8” but turned down to 9/16”. The bore in the pulley certainly looks like it could be 5/8” though I haven’t measured it just yet.

Here are parts of the fence after diassembly:



The housing that accepts the fence at the front of the infeed table has quite a bit of corrosion:

I’m hoping that it will clean right up with a bit of elbow grease just like the top.

The motor pulley is a lost cause. I think it’s warped (better that then having the shaft of the motor be bent):

The motor is a Leeson motor (pleasant surprise for me):

I couldn’t get a photo of the motor plate since the camera wouldn’t fit in there so I’ll have to take another shot using some sort of point and shoot.

The cutterhead is pretty rusted:

but the handwheels are in good shape:

The roller pin of the infeed crank looks like it was broken:

Flipping the jointer over, I was planning on removing the infeed and outfeed tables as well as the height adjustment assembly.

but I couldn’t do it because I didn’t have any pin punches to knock the pins out. The threads look like they’re in good shape with just a bit of rust and lots of wood shavings. However, they didn’t turn too smoothly so maybe the parts just need a good cleaning and waxing (at least that’s what I’m hoping).

I can’t wait to dunk all this stuff into EvapoRust and see it work its magic. Of course, I’ve never used EvapoRust so maybe my expectations are a bit unreal. :)

Assuming I can get the table height adjustment assembly off today, I’ll start to clean the parts.

You will not be disappointed with Evapo-Rust. It is a product that does what it says it does and does it impressively. Looking forward to seeing the cleaned up parts.

sIKE, you were absolutely right. Evap-O-Rust is a miracle worker! Thanks for the suggestion.
