Iron,
I'll try my best!
"Was the weapon being worked on in the photos having feeding problems before the work was performed?"
Unknown. I was routinely adressing a shallow feed ramp.
"What is the tolerance on the feed ramp depth and angle?"
From my experience, 31.5 is ideal with an 'in-spec' frame. Some frames require closer to 30.5 but this is less than ideal.
"Did you indicate the slope after getting it close with the angle gauge?"
I believe my use of the protractor gets me within 10 minutes or so. 1/6th of a degree.
"Is the .360" vertical ramp height a minimum?"
In my experience, yes.
"How was the angle height measured?"
Eyeballing a depth micrometer.
"Is the angle and the depth more important than the location of the ramp relative to the hole (.790" dimension)?"
Some frames require a steeper angle and a shallower depth. The limiting factor is the length of the bridge, on the barrel bed, between the vertical impact surface and the top corner of the feed ramp. Too short of a bridge will require excessive barrel throat set-back with subsequent loss of cartridge case support. I consider .248" length a minimum.
"Am I being to picky?"
No
".360" min +1/16 and 31.5 degrees +- 1 degree close enough?"
.360" - .420" depth x 31.5 - 30.5 degrees.
"Is there a spec for flat land between the radius cut of the endmill?"
?
"Is that a standard size endmill?"
No. It is ground to .480" diameter.
"By the way some beautiful work done over at rogers precision."
Thanks!
"One more question if any have the time to reply.
How much would a job such as this cost if done by a competent gunsmith?"
How hungry is the smiff?
