Argh....
Now I know why the 1851 navy I picked up at a swapmeet was only $75..
one of the nipples is stuck HARD. (pietta 1851 .45)
First, I broke a standard cheap-o nipple wrench..
So I soaked it in pyroil for a few days.
I pulled out the bigger gun, a 4.5mm impact socket I had ground into a good fit..
I couldn't turn it by hand, was just starting to round it over, so I moved on to the drill press. I have a cylinder jig i built a while back for an 1860, and this luckily fits. It is just 3 hardwood dowels (for 3 chambers) in a 2" chunk of mdf, and some 5/8 tbolts to hold it onto the drill press table.. then a strap over the cylinder to hold it down.
So, mounted the cylinder, chucked up the socket..
and pullllllllled...
with a screech, chunks of the nipple flats came off.
Not one to give up, I chucked up a 1/16 cobalt bit, and drilled the nipple through. then chucked an 'easy out'... and broke it off in the hole.
so, now I have a mangled nipple, plugged with the broken off tip of a screw extractor.
My plan is to drill it out again, maybe bigger.. I think I can safely get a 1/8 bit through without nicking the threads, but will try with 3/32 first, then do the boiling in automatic transmission fluid trick I read somewhere here, and try an extractor again.. I have been drilling from the back, I would have to build a new jig to try and drill from the front...
so, anyone have more ideas? I know this problem is as old as nipples themselves, and has been hashed around here for about as long.. I've been haunting all those old threads for a few days.
At what point would you say 'heck with it, a new cylinder is only $60...'?
