MedSailor

in my opinion I dont think you have enough stud for the use(correctly of the impact driver) by placing it in the chuck, some very sharp vise grips after doing the heat treatment works better in this particular case

if you care to use the method I described

Re: The WTF challenge!

Get a new boat?!?

Back home on Lake Ontario after something over 36,000 nm circumnavigator. Not surprisingly there is a lot of stuff I want to get done on Ainia both cosmetically and functionally. Getting an early start so it will be ready to go for next summer (Lake Superior?).

Fairly easy, but not a high probability of success:

Use a dremel and cut a new slot

More difficult, but more likelihood of success:

Grind a flat surface to the top of the stud, then weld on a bolt head to the top of the stud.

Try a little dab of C 4 on each one. Boom! No more bolts.

Where do I claim my prize?

Re: The WTF challenge!

Heat will expand the metal, not what you want.

Freeze it instead so it contracts, then penetrating oil; cut a X slot with a dremel or a hack saw and back them right out.

Lessons learned are opportunities earned.

Re: The WTF challenge!

well the issue you have some techniques that counter others

heat is in fact what you want if what you want is to wick in PENETRATING oil or the 50 50 mix I mentioned

heat also will crack and or melt any sort of epoxy or sealant or varnish or liquid that has migrated in the threads or not

heat and therefore the later CONTRACTION of the metal is what in reality releases the threads

if you do this more than a few times the heat thaw heat thaw is usually enough with combination of penetrating oil and some sharp vise grips to remove

last bit of advice

for those saying to cut a slot...if you do so on the stub only and especially on the ones that already had a drill hole in them you are setting yourself for the easiest crack ever

that part of stainless is extremely soft...plus you have already on most of those stubs bent and or expanded or softened the metal

the grip method compress the shaft as a whole and has a much much likelier chance of not snapping on you than the other methods provided you have used the heat method, wicking in the penetrant and most importantly

USE A COOL HEAD AND PATIENCE

peace

ps. med if you havent rebuilt any old engines before youll see that this is a walk in the park...jajajaja

last ditch(cause you need a welder) but 100 percent success rate...

a nice hex NUT(that goes over the stud) is the tried and true method

Re: The WTF challenge!

Good luck.

Heating up the remnants and letting them cool will help break the connection which is likely corrosion welded.

Someone (Popular Mechanics magazine perhaps?) did a comparison of penetrating oils. As I recall PB Blaster was the best commercial product but the 50/50 mix of ATF and acetone Christian suggested was better yet.

Hitting the stud with a hammer also helps to break the corrosion bond. Since you said you have access to the bottom you might try also beating the screws from that side with a hammer and a brass drift.

After all that ViseGrips (tm) might get them out. If not you choose between welding on a bolt head (as suggested above) or EZ-Outs (which aren't easy).

Re: The WTF challenge!

Maybe it's me but the pictures look like they're hollow. I'm sure they're not though.

My idea is to cut the bolts flush to the surface, as close as you can get then find a hole saw and cut it out off-center from those bolts so you won't be drilling the studs themselves. Then, the same size hole saw to make a plug to fill the hole (mostly) then use fiberglass and epoxy to fill/fair it and then you can retap and place new studs, if you still need them.
