Thin CA is what popped into my mind when reading your post. Keep in mind that many things pop into my mind that are not worth much.
I am curious to see what the masses think.

I personally wouldn’t do anything to them but use them.

Oil the screws for lubrication. They will work to your satisfaction with the cracks.

CA is what I would use if you want to fix them but make sure you wipe off any on the outside before it sets so that you don’t have any burrs. Use the thin stuff so that it will seep into the cracks and apply pressure by hand (wear gloves) for a minute or 2 until it sets to close the gaps. I would use the slow setting kind so you have time to apply it along the entire length at once and wipe off any excess. I often use the kind used for finishing wood turnings for filling and closing cracks or breakages in turned items.

i was kindnof hoping sombody would tell me to leave them be. i was just afraid that they might weaken it too badly. i may just do that. thanks smitty and bgood for the advice! as for you dan…....as a fisherman i can totally appreciate your rule as i observe it myself. so go to my two blogs concerning said bench lol. i did one for the gloat. but then started one to journal the rehab!

They are probably just checks.

I would wax them and use them.

I saw somewhere (might have been the Woodwright shop?), that tallow was often used as a lubricant for wood tools which is why so many old wooden tools and handplanes often have a thick patina when you find them in an antique shop. In fact they usually kept a grease pot under their benches to keep it close at hand. I wonder if they would have used that on wooden screws too?

it makes total sense to me. but then again i regularly get called an idiot lol. i mean if its good for a plane it should be good for threads right? i just thought the beeswax would be better (thinned a tiny bit with somthing, mabye mineral oil) because it keeps nice and tight especially in hot weather. id honestly love to know more about what they used back in those days. I mean let’s be honest most of the products they use for everything back in those days either cause cancer or killed you outright but darn were they good products !!!LOL

I forgot to add to my previous post…To keep is simple, I would probably just apply a thin layer of paste wax. That way you don’t have worry about getting the right consistency—they’ve already figured it out for you and it is probably less likely to to be gummy and attract sawdust.

Don’t they use mineral oil to soak the wood in for about a week before cutting the threads? Would that lubricate enough?

Not knowing the condition of the wood, I would soak them down in poly thinned 1:1 with ms, kepp them wet for ~10 min, then wipe it off. Repeat for 2-3 coatswithin 24 hrs. Could be the poly wont soak in if there is tallow or wax – I’d probably wipe down with ms first to clean. After the poly cures for a week, 2-3 paste waxings to lube them up.

oh the wood is in absolute perfect condition! i think it may be beech. they are hard, ROCK HARD . i literally ran the threads through a wire wheel on a bemch grinder to clean them up. and not only did it NOT hurt them on amy way or show ANY signs of marking them up, it polished them lol. and it was a (heavily broken in but still)steel whire wheel. not brass. its ridiculous how hard and solod these things are for the age

OSU, help me understand: Why go drown a couple ancient relics like those in 1:1 mix of poly and MS? They’re hard and stable, what’s to be gained?

1) no previous mention that the wood was rock hard, so poly isnt needed to harden the surface, but it wont hurt anything, 2) checks and small cracks – completely seal the wood to prevent further cracking, 3) help lube – friction coef of plastic lower than wood. The op is prepping them for use not a museum display. Its what I would do, there are other options.

Stupid question: will soaking wood in mineral oil cause it to expand?

That’s what I wondered as well. Expanded screws may make them unusable, a concept I understood as the intent of the OP. I wouldn’t do what OSU recommends.
