Topic tags/keywords: stanley plane screw help restoration

Hey Y’all, Picked up a very early 1910’s Stanley #5 for 6 bucks at a flea market yesterday. It’s extremely rusted.
I cannot get one of the screws out to take the frog off. It bends my screwdrivers. I have it soaking hopefully it will loosen the screw-up. Does anyone have any ideas on how to get this screw out? Thanks

Soaking it is the best approach I think.
PB-Blaster is good if what you have isn’t
doing the job.

It’s possible to heat up a stuck screw with
a propane torch and the expansion can help
to loosen it. I did this once on a sewing
machine. I got the screw out finally but the
slot was damaged.

Patience, my friend, is rule no 1 for freeing rusted or otherwise frozen parts.

What are you soaking with? a 50/50 mix of acetone and automatic transmission fluid is apparently more effective than other penetrating fluid.

I agree with patience. Soak it long enough and you won’t need to do much more.

If patience wears out, first step is to grind a screwdriver to perfectly fit in the slot (as close to zero slop as possible) with a hollow grind so the turning force is at the very bottom of the slot. Try that, then try tapping the driver end with a hammer to loosen the rust’s hold, then try tapping as you turn. A manual impact driver with a tight fitting bit could work.

The problem with heat from a torch on a frog bolt is you’ll burn off any japanning that is left around there. I’d only do that if the japanning was already shot on both the sole and the frog.

If soaking doesn’t help….heat

Drop it in whichever ‘solution of your choice’ and wait at least a week. ” It’s extremely rusted.” is a strong hint not to rush.

Soak it, in an ultrasonic cleaner. Or on something that vibrates all day like an engine. A machine shop will probably do it for 30 bucks. I do that all the time.
