I came up with this thought, but wonder if it would work and would it mar wood surfaces. You know how to season cast iron pots and pans by rubbing cooking oil on the surface and baking in the oven for an hour, then letting it cool down slowly in the oven. What if I rubbed some machine oil into the cast iron surface of say a table saw and played a heat gun over the surface until the surface was warm enough. Cooling down would cause the oil to be absorbed; a wipe down to remove excess oil would follow. I think it would work, but not sure if an residual oil would get transferred to the wood when cutting. This might just work as long as we are cutting only wood that won’t need any finish. Suppose we were to use linseed oil and our finish would be a linseed oil base; might that not work? Just a thought.

Just let them brown naturally like the Kentucky rifle barrels did. Lot less stress ;-))

I think the oil might affect the stickability of wax to
the iron.

Over time cast iron tables tend to take on a mottled
brown patina. I like it and when I remove surface rust
I try not to remove the patina underneath.

From what I’ve read on the net seasoning cast in the oven with high temp causes a chemical reaction with the oil on the cast iron you won’t be able to get high enough temps on the large castings for it to work if you want more info google cast iron seasoning

I baked flax oil on my Benchcraft hand wheels at 500° for 2 hours, I did 3 coats. They look awesome and the flax oil bonded to the steel beautifully. I seriously doubt that you would get any kind of similar results w/ a heat gun on a large surface. If you could bake your table saw in the oven it would work great.

Fine Woodworking had a review on rust preventives a few months back. Don’t recall the results, but some of those we instinctively think are good turned out not to be.

I think controlling your temperature and humidity, especially the latter, is a better way to go. Excessive humidity will be gnawing away at other stuff (like electrical components in you saws) and doing harm there as well. I have a dehumidifier running 24/7 in my shop.

Uneven heating could crack your saw top. Cast iron is strange and unpredictable when heated.
