Thanks novo, that's destroyed any shred of optimism I had left ;-)

Well, I guess the message is that it will come off, one way or another!

The Fowler key was a bit extreme. I'd never seen one stuck that hard. I'm sure your's cant be that bad.

Re weld and try again, my petter AV1 broke a couple of times before i got it to move. In the end what i did was knock the key in a fraction, this was to makes sure the rust seal was broken, after that it took some hitting but it did come out. Hardest one i have ever come across but i haven't come across many in my short time restoring engines, only four but they came out easy.

Update:

Well, I've learned a lot about arc welding and slide hammers... but the key aint moved a millimetre!

I prepped the key, threaded rod and 'fillets' properly - the edges all filed down to give a decent in-fill/bead between the bits being welded. Also chipped and brushed between beads. Got a weld I'm dead chuffed with AND kept the mask between me and the piece for every arc!

So now I have a weld I can't break!!! The limiting factor now is that I have an M10 threaded rod welded to the key but I don't have a proper slide - I've been using my 1 ton vice clamped round a bit of steel tube to avoid damage to the vice jaws... and I can give the assembly a damn good smack with that - enough of a smack to make the entire engine and trolley base jump across the floor... but the key wont move. Physically, I could give it a bit more welly but the vice just aint the right thing to use - it swivels and comes away from the rod.

Anyone in the IP5 area with a M10 slide hammer weight I could borrow??

Cheers!
Dave

Dave,
Are there any scrap metal dealers near you that you could go to. You could have a look at if they have a lump of something you could use. It's not so much brute force, but the percussion of multiple hits quickly.
You are nearly there fella!
And...... Where are the photos? Pop some on, and some of the more expert guys may be able to help with ideas.

Andy

Andy, as requested, photo!



Not the greatest weld in the world but it's holding up so far...

I'll post a more complete set up photos on my main project thread (and link from here) since there's photos of the engine before it was disassembled on there.

Cheers!
Dave

Cooo Cooo

Only messing. Thing with welding is practice, and seeing what happens as you alter the current settings. Your weld certainly looks like it would hold up to some slide hammering, so just have a look about for a heavy lump to use.

Try giving the flywheel a bit of a tap towards the engine. It may help free up things a little. You are only talking fractions of a thou.

Good luck, and your nearly there fella.

Andy
