StraightUp_OG Posted February 24, 2013 Author Share Posted February 24, 2013 (edited) Also, it will be very hard to get your part on and off of those tall locating pins. They only need to stick up 1/2" from the tooling plate. Drill and ream your holes in the part .001 over the size of the pins. Then you will have repeatable location and it will be easy to work with. That's a very good great point. I've actually seen pin locations grow farther apart while machining. Granted they were about 100" apart, we were throwing chips about 20 feet, and we were cutting 1.250 7050T7451 plate down to .1875 floor thicknesses. But still when we went to flip the part it was hard to get off and would not go onto the vacuum fixture with identical pin locations. Ooops.... Went off to program new pin locations for the initial part and repost g-code. Toned it down just a tad too. LOL I will keep this in mind and make the adjustments but my little mill won't throw a chip 20 inches let alone 20 feet. Edit: Holy crowbar Batman! You guys weren't kidding those long pins would have been a nightmare! Thanks for all the insight! I made the adjustments and it is almost ready to go again!

StraightUp_OG Posted March 1, 2013 Author Share Posted March 1, 2013 (edited) You gotta threadmill that action thats what cnc is all about. True dat. I will do this but the tap was only $75 the threadmill in this size is a few hundo! So the wallet won this time.

StraightUp_OG Posted March 3, 2013 Author Share Posted March 3, 2013 ? @ Toolguy Et al - What diameter ball end mill do you use for ball cuts on the slide by the spring tunnel? Link to comment Share on other sites More sharing options...
Toolguy Posted March 3, 2013 Share Posted March 3, 2013 I don't know. I only shoot S&W revolvers. Get a set of radius gages. They don't cost much. Then you can check a slide or frame anywhere you want and know what size it is. Remember, a radius is half a diameter. If a 1/4" radius gage fit on the spring tunnel, then you would use a 1/2" diameter ball end mill. Link to comment Share on other sites More sharing options...

No thread drift intended but for those of us inspired by this thread here's a good youtube on threadmilling. thegeekgroup is a cool channel on youtube, 16+ videos on cnc training.

sarpau Posted March 3, 2013 Share Posted March 3, 2013 Cool vid. Loved the safety disclosure at the beginning. I picked up a manual mill last year and learning how to use it. The long term goals are to convert it to CNC. Hopefully in the next couple years. This thread is pretty inspiring and I'm picking up quite a bit of info. Thanks to everyone who shared their input. Will continue to follow this and learn along the way. Link to comment Share on other sites More sharing options...
jid2 Posted March 4, 2013 Share Posted March 4, 2013 You can thread mill with a 60 degree cutter. Like this. Link to comment Share on other sites More sharing options...

StraightUp_OG Posted March 5, 2013 Author Share Posted March 5, 2013 Your machine is so Bad A$$! It's what mine wants to be when it grows up! Good thing I don't have kids, if I did they would be shoeless and hungry! ;-P My new Weigand barrel fitting jig. Link to comment Share on other sites More sharing options...
Griz Posted March 5, 2013 Share Posted March 5, 2013 In my opinion, the main benefit of that jig that wouldn't be easy to setup without it is the ability to cut the radius on the feet.... How hard would that be to do with CNC vs buying a jig? Link to comment Share on other sites More sharing options...
jid2 Posted March 5, 2013 Share Posted March 5, 2013 Your machine is so Bad A$$! It's what mine wants to be when it grows up! Haha, my machine wants to be bigger, faster, and have a tool changer.

How hard would that be to do with CNC vs buying a jig? Not sure but even if I write some code the jig seems to be absolutly usable for the CNC process. And it it seems VERY easy to use manually.

donnyglock Posted March 11, 2013 Share Posted March 11, 2013 Nice!!! I just bought a mill and tooling to start my own build. Its exciting stuff. I can't wait to see your finished firearm. Link to comment Share on other sites More sharing options...

StraightUp_OG Posted March 11, 2013 Author Share Posted March 11, 2013 I will try to hook up the vid for the next build which will be a STI commander length 40. Bummer about your trials and tribulations this weekend hope the vise is not too hurt. At least you didn't smash your thumb with a dead blow hammer while fitting a slide...

jid2 Posted March 11, 2013 Share Posted March 11, 2013 Vise is fine, that carbide cutter made easy work of the steel jaws. I put the correct parallels in place, re-zeroed and got back to screwing other stuff up! Link to comment Share on other sites More sharing options...
StraightUp_OG Posted March 18, 2013 Author Share Posted March 18, 2013 Well this bad boy is almost shoot-able. Fit the barrel (Bar-sto) but the STI grip safety just was not in spec so I ordered a EGW Billet tail and what a FANTASTIC part. Plenty of meat and was a joy to fit. Blended the back of the slide (Caspian) and right side ambi (C&S Tacticool). Shaping up to be a fine .45 carry blaster. Going to ship it off to Springer for a 2 tone DLC tan lower and black top but there is a lot of work left to do before calling UPS. Link to comment Share on other sites More sharing options...
