Hi, folks,

It appears that my kiln, irritatingly, dropped its power I saw this when it had gone from 820 to 750 degrees mid way through the "hold" process of 1 hour of the annealing time.

I've now ended up with a hard crust (Which I assume is the old hardened metal" on the outside of each of the parts I have annealed.

It's probably an irrecoverable disaster but I wanted to check to see if anyone might advise on how I can remove this. I've taken a photo of one of the side plates that I have cleaned up next to one yet to be cleaned and you can see the mess the other one is in. I can of course clean the hammers and the side plates in the same way. My problem is the action.



Now clearly I'll have to get the gun re-faced which is irritating (I think I will anyway) because the surface I remove on the action face will be enough to create a gap. But how the heck am I going to get this layer off the inner parts of the action? Does anyone know of a chemical that might just take off the crusty metal??

Any help much appreciated!!

PS I followed Oscar Gaddy's piece from the journal a few years ago.

Regards,
Tony
