My Delta DJ-20 Restoration (Part 3)

Turns out, you have to unbolt the jointer from the base and flip it on its side to be able to access the inner screws holding the tables down.

The next issue was trying to remove the spring that makes raising the tables easier. Its basically impossible to remove the spring while under tension. You have to remove the tables as best you can and position it so that it will release the tension on the springs. After that its easy to use some pliers to get the spring off.

Here's a pic with the tables off. It took some time to remove the eccentric bushings used to level the tables. You have to remember to remove the 2 set screws for each bushing (one stacked on top of another). Removing them gives you a nice port for squirting a little WD40 to help loosen the bushing. Then I used a 19mm socket and a rubber mallet to tap the bushings out.

My Delta DJ-20 Restoration (Part 2)

I'm trying to remove the tables, but I just can't seem to figure out how to do it.
The tables have rods on which the arms for the parallelogram mechanism clamp onto.
Here I have loosened the socket cap screws that clamp the black plates to the rod. (Plates rotated 90 degrees)

Its hard to see, but there is another set of socket cap screws way in the back. I can't figure out how to loosen those screws. And if I did, I'm not sure how I would but the tables back on. 

Here is a spring that helps counter-act the weight of the tables for easy adjustment. If I remove it, I'm still not sure how I can put the springs back.

My Delta DJ-20 8" Jointer Restoration Project (Part 1)

I have been looking on Craigslist for an 8" parallelogram jointer for over a year now. I finally managed to score this Delta DJ-20 8" jointer (model 37-350) with a Byrd Shelix head for $800. There is some rust, but the tables only have a little bit of pitting in about 3 spots.

You can see here there is a bit of rust on the fence assembly.

Here the paint on the aluminum guard is pretty worn.

Here the table height adjustment mechanism is covered in a combination of sawdust and rust.
