Any tips?

Tote bolt sheared while trying to extract.

Bought this one in this condition. Figured i would drill out the center and try and use extractor.

If you have a drill press, try to use that to drill it out. I find that trying by hand then Murphy’s Law will make sure that the hole shifts over and trashed the threads.

Soak it in penetrating oil as much as you can first. You can try to cut a slot in it to get a screw driver but there’s not a lot of room to work with. Start off with a small drill bit first to get started. That way if it walks a little on You the threads are still good. An easy out will work but you might have to add some heat to it also.

Update on Stanley No. 7
Tried soaking in WD40 for 24 hours. Followed with blowtorch. Got it hot enough that when I spit on the plane it boiled. Tried to turn with big pair of pliers. Sheared again.

Tried cutting slot for screw driver using dremel cutoff wheel. Stripped the slot when I tried to turn it.

…. Sigh…..

Guessing I will try and drill it out next. Soaking in 3-in-1 oil now

3in1 won’t do any good. WD40 isn’t that good either. Try PB Blaster or the CRC stuff.

I would not use heat. I think you should be very careful heating it could warp the plane.

I would grind off the exposed screw, drill and try an extractor. Try a left hand drill bit sometimes you get lucky the bit grabs the screw and voila! If extractor does t work, you have to re tap it. A bottom tap if you can get one.

Have you determined the thread config for that screw?

Like Robert said, WD40 and 3 in 1 won’t help with these bolts. My favorite is Kroil but PB Blaster works well too. But you need a penetrating oil to get down in there.

Robert / Hokieken

I will try one of the products you have recommended. Thanks!

I had that thought about the heat…decided it was worth the risk (mostly because I’m impatient)

I have not determined the thread configuration for the tote screw. Looks like about a #10 screw.

Wd 40 makes a penetrating oil also. The regular stuff doesn’t do much. Only need heat at the screw. Doesnt have to be super hot. There’s 12-20 tap and dies available right now if the threads get damaged

Your threads are #12-20 Will. Like corelz said, you can buy taps and dies from a couple of places but they are not commonly available. If the plane is strictly a user, you can easily chase them with a 1/4-20 tap and hardware is readily available for those. If you want to keep it original though, you’ll either need to not damage them or buy a 12-20 tap.

Kroil is pretty much unbeatable in my experience for breaking corroded threads. If you don’t have any other penetrating fluid on hand and have to buy something anyway, that’s my recommendation. Do you have a soldering iron? You can heat the bolt without risking warping the casting by holding the tip of a soldering iron to the end of the bolt.

Use penetrating oil, but if there is enough to grab, you should heat, and wiggle, heat and wiggle and keep getting it hotter until you feel it start to move. Then keep heating and wiggling until your sure it’s loose enough to come out
