Rick, that is very interesting. I've never heard of a gunsmith using a shaper before.
I'd love to see more details, and photos of your 1911 setups.

I used the slide to frame fit as an example that first came to mind. I mostly work on old guns that don't always
have parts you can just order. I am not a parts changer gunsmith for hire. I buy guns that have been all screwed
up from people and gunshops. The ones that have been worked on by someone that has a file and a stone and
are the new trigger job expert. They round the sears. The one stroke ability on my shaper is able to cut a perfict
new sear. You insert a pin thru the hammer pivot and rest it on the top of your vise jaws and then clamp the trigger.
Now you use your 1 stroke jog button and with a magnifing glass, true the sear notch (1 stroke at a time). Then
do the same with the mateing sear. I have yet to not get a perfict new mate of the 2 parts.
A shaper will cut weld built up areas back to the original surface of badly worn parts, the last 2 or 3 cuts (1 stroke
at a time) so you don't overshoot your size you want. End mills don't like to cut welds, a shaper don't care.
A lot of older gun parts were made with shapers, why not use one to do major repairs? When Remington closed the
New Haven Marlin plant there was a picture in a magazine of the old machinery that was going to be replaced
with CNC. There were wbout 20 machines in the picture, 1/2 were shapers with fixtures on them.
