Angle Grinder or Multi Cutter Tool for Seacock Flanges

[John the kiwi]

As an apprentice i used 4 inch to 9 inch angle grinders with grinding and cutting discs according to need.
I have the scars from a disintegrating 9 inch disc to remind me!
A few years ago, along came the multitool. Not fast, but can do one trick a disc grinder can't: - cut absolutely flush to a surface with the right blade.
The Op wants to flush cut a sea cock. I think a multitool with the right blade is ideal.....
a bit slow, but absolutely controlled.
Good luck

If I wanted to remove bolts from something that I did not want to damage, in this situation id not even consider a oscillating multitool to remove/cut bolts. Id grind the heads off and then punch them through very carefully from the outside in.

Nothing wrong with that. It only holds the bolts in place. Just re-assemble the valve inside with sealer.

"Sealer" I want it to move still.....????

No you bed the valve inside on sealer so it does not leak!

Do you mean the inside bit inside the blakes seacock. If you mean the whole seacock if I have got that far (which I havent) I might as well replace everything . At the moment i have freed up three of the nuts and attempted to heat the inner part and tapped it hard from outside but so far no luck freeing it up if I can epoxy the seal .....

I did hear that when westerly were building they bedded the screws in the wet epoxy that beds the wooden base down so not gonna be easy to remove the whole seacock anyway

If that is the only thing that's wrong with your Blake I would say that you're going to waste your time and money! Get a tin of epoxy putty and fill in the missing bit; it is not structural.
Your boat, your time, your money and your choice.

As an engineer I would say that should be changed. No sign of impact damage so it has gone brittle, electrolysis ?

As a boat owner I would without a doubt say CHANGE THE EFFING THING NOW.

How old is it?

Potentially been on there since 1977. It was bent up slightly where it is broken off before I tried knocking it back flat with a rubber hammer which is when it broke off
It is possible that the previous owner was trying to pry it off during a refit.
