[Shop-talk] Removing a dove tail gun sight....

[Gerald Brazil]

 I am trying to remove a dove tail rear iron sight so that I can install a
mount for a scope. I have made a block of wood to hold the barrel in my vice
and it holds it quite nicely. I have been using a brass punch and a pretty
big ball peen hammer to hit the punch. I have tried going both directions
with no success. I have no idea if loctite was used when the blade sight was
installed. If there was a way to super cool the sight without cooling the
barrel it might loosen it up but since the sight is so small if I put dry
ice on it the barrel would probably cool down too.



So I thought I'd see what suggestions come from the collective wisdom of
Shop-talk...any ideas?



Thanks
