Topic tags/keywords: question plane

So I picked up a old plough plane at a woodworking fair. Everything seemed fine on first hand, until I decided to check the depth adjustment at home witch didn’t work. I noticed there was a lot of grime around the depth adjustment screws and in the treads, unfortunately I have no idea what to use to soften the grime without damaging the wood itself. Neither do I dare to turn the screws by force at any point. Does anyone know of some sort of cleaning agent that can take care of the grime in and around the screws treads without destroying the wood itself?

The depth adjustment consist of a long flat strip of iron running over the length of the plane, using 2 screws for changing the depth. Both screws end into a flat “O ring” at the top. I will post a picture later for clarity.

Mineral spirits and a tooth brush will do no harm. A picture will be good, too.

When I find wooden hand planes I sometimes use BLO to loosen up grime on the body and re hydrate the wood a bit, I learned this method via Paul Sellers. I don’t know if this would work for the threads though, so take this idea with a grain of salt :)

Murphy’s oil soap.
Works well with all wood body planes.
Cleans, “crud” and doesn’t hurt the wood.

Smitty_Cabinetshop,
Mineral spirits could be a option, but how would that fair when applied to the treads themselves?

Marn64,
What exactly is BLO? I never heard of that term/product before.

ksSlim,
We unfortunately don’t have Murphy’s oil soap in the Netherlands.


The “grime” is rock hard at this point, I could apply some WD40 with a piece of cloth to remove the worst, but I’m mortified to put it even close to it.


Depth adjustment and the skate.

Boiled linseed oil, its usually used as a wood finish but its quite oily and can be wiped off before it dries. upon reading other suggestions from others, I would actually ignore boiled linseed oil, Mineral oil is a better option.

Yes, I would try mineral spirits first. Called white spirit in the UK I think. Its a solvent, also used as oil based paint thinner. It won’t hurt the wood, but it you really want to be careful you could tape around the screws with painters tape.

If that doesn’t do anything, you’ll have to try something else. Is that a brass or steel screw? Try testing it with a strong magnet. If it’s steel you can use something like Naval Jelly, a jelly like form of phosphoric acid to get the rust off the visible threads, but if it’s brass, I’m not sure what to get the corrosion off with.

All, but the wingnuts on the fence are steel. I will grab some mineral spirits at the local paint shop when I have time. We unfortunately don’t have the same range of brands as in the US/UK, so a lot of specific products such as Naval Jelly don’t exist here.

I didn’t think you’d have that brand, but I’m guessing you might be able to find something like it if you look around for rust removers.

Are those screws going directly into the wood or are there some metal threads of some kind inside?

A little penetrating oil down the threads shouldn’t do any harm. Keep it wiped off the wood as much as possible and you should be OK.

Tim you would be surprised how few good chemical rust removers there are here ever since environmental laws banned most of them. There are only 1 or 2 eco friendly ones that actually survived the transition with a good product, the rest are all rust converters.

The screws are directly going into the wood.

I’d recommend getting a nut with the same threading and using penetrating oil on the screw for a few hours before threading it through the nut, this should leave clean threads.

Mike that isn’t possible due to the “O-ring” at the top of the screw (see pictures). Though I could apply it with a piece of cloth and brush it off.

Can’t hurt. Better than water, not a thick as oil. Apply, brush, repeat several times, and see what happens. It’s either a static display piece / artwork or a tool. Which one you want more determines how much risk you’ll take getting these bolts working again. The mineral spirits won’t damage wood; might dull the finish, but that’s easily addressed once the plane is working again.

Ahh, well in that case just penetrating oil, you may try cutting a nut in half and using one half to trace the treads, if you hold it tightly against with cushioned pliers it should pick the residue out.
