rhlowe Posted December 1, 2005 Report Share Posted December 1, 2005 Does anybody have a close up of a 21 safety that they can post. I am converting a Savage paddle to look like a 21. PK was quite helpful and advised that the hole that goes through the paddle in .209 but advised that the hole is chamfered with a concave recess. I would like to see a close up of this.

PK. Posted December 1, 2005 Report Share Posted December 1, 2005 That radius is convex. Link to comment Share on other sites More sharing options...
rhlowe Posted December 1, 2005 Author Report Share Posted December 1, 2005 PK: You are always a gentleman and very helpful. I think that we are trying to say the same thing. I looked up convex on dictionary.com and they said "Having a surface or boundary that curves or bulges outward, as the exterior of a sphere." Concave they said "Curved like the inner surface of a sphere." Now one of us is using the wrong word or I am confused about how the safety looks. Well, I know I'm confused or I wouldn't be asking this question. If you drill the hole and then run an oversized ball end mill into it, that is the way to form this feature? Maybe Arthur has a photo of this part from one of his Colt's that he would post. He was most helpful on my last post. Link to comment Share on other sites More sharing options...
TD. Posted December 1, 2005 Report Share Posted December 1, 2005 Richard, This is the best picture I have of the Safety and Fire Control Lever from a Colt Thompson. Hope it helps. http://img.photobucket.com/albums/v669/Auto-Ordnance/165_6553crop.jpg Link to comment Share on other sites More sharing options...
PK. Posted December 1, 2005 Report Share Posted December 1, 2005 A ball mill will produce a concave radius; the opposite of what you want. To properly form that radius like a Colt part using a machine you will need to get a custom cutter ground. Link to comment Share on other sites More sharing options...
rhlowe Posted December 2, 2005 Author Report Share Posted December 2, 2005 Pk: Dang, It is convex, just in the other direction than I was thinking. I can do it in the lathe. Is there a flat in the middle of the hole or do the two convex surfaces meet in the center? U like this or like this \_/ But rounded Thanks, Richard Link to comment Share on other sites More sharing options...
rhlowe Posted December 2, 2005 Author Report Share Posted December 2, 2005 TD: Thanks for the photo. That is a great help. Man pretty gun, yours? That photo helps with the surface finish a little coarser than I would have thought. Probably somewhere around 320 grit? Thanks, Richard Link to comment Share on other sites More sharing options...
PK. Posted December 2, 2005 Report Share Posted December 2, 2005 They weren’t all exactly the same; a short cylindrical section can be found on some, others not. Whatever you do will be fine I’m sure. Link to comment Share on other sites More sharing options...
