Here’s another post on the drill press. I’ll skip the tear down of the machine since it’s just removing nuts, bolts, screws, and snap rings. I will cover how I’m cleaning things up though. This post is on cleaning up some of the smaller parts.
I don’t know where this drill press worked previously but it was somewhere with some pretty tough adhesive. Here’s a picture of the chuck with the adhesive on it.
It didn’t stand much chance against a wire wheel chucked in my small drill press. Yes, you can chuck the wire wheel up in a regular drill so you don’t need a drill press to restore a drill press. Here’s a picture after cleanup. I’ve since filed down the burr.
Below are some pics of the Reeves pulley that are pretty rusty. I probably could have wirewheeled them as well but instead chose to use electrolysis.
Here’s a couple of the pulley halves in the electrolysis tub. I use baking soda and an old battery charger. Leave them in there for an afternoon and they’ll clean right up.
When you remove items from the electrolysis tub they’re coated in a black gunk that is primarily iron powder. This is shown on the left side in the picture. A light pass with the wire wheel removes it easily leaving a clean surface as shown on the right side.
This process was repeated on all the pulleys and they cleaned up well. The one on the top right could have used a little bit more cleaning but it’ll be ok. Once they’re cleaned up you want to oil, wax, or use some other protectant to keep them from rusting again. The small dark spots comes from where the rust has eaten into the surface The larger holes are where the pulleys have been drilled to balance them.
There are six handles with knobs on the machine. Three lower the quill and the others vary the RPM of the drill press. The easiest way I’ve found to clean small round things is to lightly chuck them in the drill press and use sand paper to remove the rust. Here’s a picture of one of the handles that varies the RPM in the drill press. A little 220 – 400 grit sandpaper will clean them up nicely.
Here’s the finished handles. I polished the plastic knobs using some Mag and Aluminum polish. They cleaned up well despite not having a smooth surface initially.
Well thats it for now. I’ll post again in a little bit about cleaning up the bigger cast iron parts.
