no previous part Part 1 of Delta DJ20 Jointer Restoraton series Part 2: Making Progress »

I recently purchased an 8” jointer on Craigslist. I wanted more capacity than my 6” jointer. It only cost $200 but needs some work. Motor runs smooth but it has a lot of rust. The owner stored it outside for some time. At least he covered it with a tarp.

I started with the base. Removed the bottom, black section, cleaned it, primed and painted. Then made a mobile base. Used a Rockler mobile base and purchased some 1 1/2” square steel tubing. Drilled the needed holes, primed and painted again.

Next removed the cutter head. The knives are nicked. Will purchase new ones.

I started cleaning the top side portion. Used a small wire brush. This cleaned up fairly well. I don’t think I will need to repaint.

I will start cleaning the top this weekend but I wanted to do a small test. I used a very fancy rust removal chemical; toilet bowl cleaner. This is the result after 15 minutes.

Nice score. Very nice tip about the toilet bowl cleaner. Never heard of that one before. Any particular brand or type?

I worked in a shop that had the DJ20, it was a good machine. I also liked how tall the fence was on it. It was definitely a little bit higher than on my Grizzly 8”

Good luck on the restoration! I hope it works as well as the one I used.

Scott; I used “The Works” toilet cleaner. I’ve used this in the past to restore old hand planes. I suspect the acid in this cleaner is similar to other toilet cleaners.

Congrats, I like the cleaner you used, I had heard of this before but had totally forgotten about it
