HELP-I’ve had a problem off and on for a long while. I make some projects which have moving parts which are nestled into rebates and others that are held together with rare earth magnets. The tolerances are pretty close. I’ve used several different finishes such as clear spray enamel, shellac, poly and lacquer. I notice the problem most in hot humid weather which we have a lot of in central KY. The parts will stick together and have to be kinda whacked to make operate. These projects are dry as some have been finished for some months. By inspection I can usually see the little spot where they stuck. Usually use fine paper and remove roughness and rewax the whole surface which will then operate as it should for some time then later will become stuck in usually a new place. I think I have heard of some type lub to be used on these type of sticking areas. I will be watching for your answers so thanks in advance.

Some folks lub things with Johnson’s Paste Wax.

You could use a dry film lubricant containing molybdenum if discoloration is not a concern.

What about dry Teflon spray or dry graphite lube?

I use a cutting wax and it has given me good results.

I remember using bar soap to lube wood drawer slides and that works well!
Don’t know if it would help your project, but it wouldn’t hurt to try it.

Paste Wax. I made an mdf table saw wing and sealed it with poly. Plywood would drag a lot so I used paste wax and it’s super slick now.

I had the same problem with a wooden plane I made that had an adjustable mouth. The stupid mouth would stick no matter the lubricant I tried. Paste wax and teflon lubricant did nothing. The only thing that ended up working was dry graphite powder. It works like a charm even under pressure.

I get pretty good results with a HD product called Dri Slide. Don’t know what is in it but it keep band saw box drawers from sticking. Spray or wipe on. A little goes a long ways.

Your problem is wood movement from moisture. I build wooden geared clocks and have the same problem. As humidity increases the clock slows down and if it gets high enough (humidity) the clock will stop. What you are doing and some of the suggestions may reduce the effects of moisture. The only real way to dure it is to increase the tolerances and even then when the humidity gets really high like it can in Kentucky you may just have to live with it.

Parrifin wax does pretty good. You can buy it at the grocery store for a few bux. It’s usually near the canning supplies.

Thanks to ever one who commented for your advice. I have been waxing w/Johnsons or rubbing with paraffin, for years, but the sticking has shown up sometime in the last couple years. I was thinking maybe it was the new formulas being used in finish to meet government standards. I will try some of the ideas you all suggested. I guess I really want an easy solution.
