Very impressive and that rifle looks great. Bet you could make some money making those stock sets for sale.

The Jank Continues Part 1 I decided to try and eliminate as many variables as I could on this attempt. I started with the 1in round stock and faced the ends but didn’t turn the diameter. Then, I made a better v block with a deeper v to hold the part more securely and used a center finder. This is how I bored the hole originally but this time I decided to use end mills instead of drill bit where I could. They don’t seem to wander as much. I still needed to use a .468 drill for the threads though. So I stepped up the drills very slowly until I hit the final size. Then I threaded it again and… it was off. Again. Sus as they say. Anyway, I have to fix this part. I left the tap in the chuck and threaded the flash hider back onto it and snugged it up tight. I used the lathe tool to turn it down so that it was concentric with the threads. This was a little hairy, taps can snap so I didn’t want to put too much stress on it. I managed turn off just enough to get it back into a collet to finish turning. After that I ended up with a flash hider blank that’s threaded and concentric but… with an off center bore. So back into the v block and locate center again. Attached File Then bore it out with a 9mm end mill and open up the end with the 1/2in cutter again. Attached File Cut the grooves again. Attached File Shape it up with lathe tools followed by files. Attached File Voila. Attached File Except it was still off… The 1/2in bore is out of round by .006 and the 9mm bore is out by .010… this won’t do. Something is definitely wrong here. Time to take a closer look at the mill… |

Speaking from experience, the problem is you are using a mill instead of a lathe. I've done a lot of sketchy stuff like that with a drill press and mill. Oh, how much easier it was when I got my old lathe.
Try making a threaded mandrel to mount the part. Mount a piece in the collet and turn it down and thread it like the end of the barrel. Once you've drilled through and threaded the part, screw it onto the mandrel and mount the mandrel in the collet to finish bore and turn down the OD. Everything should then be concentric, or at least close enough for government work. ETA: Don't drill the initial hole all the way through the part in one direction. Go half way from each end. |

View Quote That’s what I did, I just used the 1/2-28 tap instead of a custom mandrel. I honestly really like getting advice that I’ve thought of already, it makes me feel like I’m not a complete idiot The Jank Continues Part 2: After careful inspection of the mill head, I figured out that it wobbles a bit when I raise or lower it. I spent some time monkeying around with the z axis gibs and got it tightened up. Usually it’s locked in place to make cuts and I’ve only been drilling soft things like wood and aluminum. The harder steel, the size of the cutters and my… unorthodox techniques made it stand out. Should have checked that earlier. So following this, I took some of the advice from @brass. I didn’t have any hss stock small enough to make a boring tool but I did have a small v cutter with a broken tip. The edges were still sharp as hell though. Perfect. So into the vise it goes to play single point cutting tool. Also broke out this mirror and a flashlight… this is going to be tricky stuff. Attached File Performing surgery. Attached File Let’s check the results. Attached File I managed to get the runout down to .0005 on the the through hole and .0000 on the 1/2 bore and most importantly, it’s all concentric to the threads and outer diameter. That’s definitely close enough for government work. The one I made a few days ago? That one is trash. This one is perfect. Many lessons were learned. Still looking cool out there on the front.

Beautiful, I love the walnut.

I see what you did.

Cool beans! I'd have thought he 6 mil was not so bad but half a mil is better yt. I guess the test target will tell how well you did overall. Only accuracy issue I see is the non free-float barrel but should be consistent and able to be accounted for if you don't stress the wood.
It looks rest! Need a game screencap and a photo of this one side by side to prove cosmetic faithfulness. Have you ever done the bearings on the mill to get it more stable? |

You can get a finish match by ordering colors from Laur: Colt Blue-Brown, Silver, and Blue Metal. Layer with airbrush mixing the colors together and airbrushing in the streaks and you can get it close. Otherwise you can put down a layer of blued metal, silver mixed 70/30 with blue, then very thin coat of mostly silver, then full layers of blue then black and after it is cured for a while, use steel wool through in various spots until you get down to the layer or silver or base blued metal and then when you have the right layers sanded down to visible, hit it with clear coat and you'll have a solid match. If you have an airbrush it's around $100 in color and clear. Could also use Cerakote with similar layering and sanding down. |

A little update, working on an x axis power feed for my mill.
Drilled and tapped the left hand side plate. Attached File Made up a motor mount plate from aluminum stock. I’ll probably remake this in the future, it’s actually pretty crude. Well… the whole thing is really. Attached File I’ve got a wiper motor to power it all and a 9/16 socket with 1/2 drive that I turned down and drilled for a cross pin. Attached File It slides in a slot in the lead screw to engage or disengage the feed… in theory. Attached File This is all temporary for now. I need shorter mounting bolt and other assorted junk. Simple sliding clutch needs to be figured out. All that stuff. Just trying to get the mechanics done so I can wire it up and test it out. I also picked up another walnut slab for future projects. I’ll have to remember to take a pic of it. |

Looks great, instead of using an edge finder to get center.
