Lots of nice fixturing lessons learned here. I keep watching mini cnc and mill videos in hopes of one day having a pallet arrive. Can't imagine having a tormach show up.
I bought my used and have been very happy with it. I wish you the best of luck. Machining your own parts is very rewarding.
@@LastBastionLabs A mini machine shop is a retirement hobby that I'm looking forward to
Love the safety checks, a great spoof on so many internet RSO'S.
Very nice entertaining and informative!
I live in Eaton Rapids MI. and just got my 440 4 weeks ago. I have been doing manual mill and lathe machining for about 2 decades in my home shop.
Biggest struggle right now is getting my cam models to cam...slow going but I am learning.
Looking forward to more of your videos.
Thank you Bob! Do a lot of simple parts and you will pick up cam faster. The first 100 parts are the hardest. LOL
This was a very interesting video since I own a Government issue Colt 1911-A1. The housing on mine is a very tight fit by the way. The checkering on mine is not worn but it is pretty flat top for checkering. I know there are after market parts that they have several different arch shapes to better fit some size hands. It would be interesting to see how it would change the balance if you used the aluminum part since it would not see hard military service. Looks like you could easily cut a new beavertail grip safety as well. Heck you could make the hole frame. if nobody checked you. Stainless would make some nice parts. If I only had a CNC mill! Years ago I had my 1911 reworked at the Rock Island Arsenal to improve the fit and action and add adjustable sites and modified to feed semi-wadcutter for competition shooting, but now way to old for that.
Thanks for commenting and subscribing! I think you need a cnc mill also! My next 1911 video will be making the mainspring housing out of steel with making the lanyard loop.
I was going to get a mini mill so I could do projects myself but after watching this video, I think I just need to make friends with someone who has a mill in their basement who works for scotch.
LOL that is one way to approach it. My goal with the channel is to help inspire others to join the hobby. Machining in the privacy of ones home has never been easier. I'm 99% UA-cam trained. Side note, my shop is in kit form in my garage. We moved and I am finishing my new shop in a pole barn.
Good video Tim, I can not wait to see the next video when you add a lanyard loop to the main spring housing. :-) Keep up the good work!
Thanks Chris! Yeah me too. Maybe I will get my neighbor to help me with that one.
Very cool!
I don't think a loose fit will affect accuracy. A precision fit is mainly aesthetic
i use i little tormach when my HAAS is down, (Rarely) and i think its better suited for smaller than 1/2" end mills on any metals. (I wouldnt even want to do steel on it) Ill use a 1/2" on proto foam, but ya, that thing is so rickety. Oh and you can get a drill through a side hole if you bore it with an end mill 1st. But always try to design a flat for holes. Not always possible though.
I have had great luck in steel and stainless with 1/4 cutters on my Tormach 440. I have another video where I make the same part in steel and I milled a pocket for that .280 hole. Worked much better. Thanks for the comment.
This looks like it'd be something I'd love to get into when I get around to retiring. Hopefully some 3D printing experience and CAD work transfers over haha
Congratulations, love your work
You are a great machinist.
Wow, thanks
My dad gave me some of his ATC stuff. Retired USCG after 34 years.
That's Cool!
Very classy calling it the Jesus hole as it acknowledges the fact that Jesus should be the point of reference in our lives as far as how we should be and how we should act
Man, I really enjoyed that. I'd have loved to see more of your CAM setup, since that would have filled the story in a bit for me, but that was very enjoyable as it was. Looking forward to the steel part, and hopefully some CAM there, as well as some direct comparisons of your feeds/speed in steel versus aluminum and what that meant in difference in machining time!
Thank you Bill, I will be sure to include some of that info in the steel video. This was my first talking video and I was not sure what people wanted. I only have 40 subscribers and I don't think any of them have cnc. LOL
@@LastBastionLabs Starting about 18 months ago, I converted a little harbor freight to CNC myself with my own design...3 times, then converted a PM-25 to CNC and by that point had moved from GRBL to LinuxCNC. Got a used Tormach PCNC1100 and get it put back together and working well. That gave me the confidence to buy a new 1100MX. Pathpilot felt immediately comfortable because I was already using LInuxCNC so it's been a fun process.
I do small production runs for my own companies and make things I enjoy making. I am subscribed to several youtube machining channels, and this video was great. Keep at it, you're hitting your stride!
@@billstrahan4791 Thanks Bill, just like you, it's been a long journey but a good one.

Thank you, I have some exciting stuff coming next year.
Make a flat back version and your serations will be aesthetically correct.
I want to get a tormack installed into an underground bunker ❤
That's beautiful.
Thank you! I was pleased with it also.
Super coo! Oh beautiful machine
Thank you!
I’m building some repro m1911a1s right now. 5 in total for all the guys in the fam. I’d love to buy five of these in carbon steel when you already to make them. I’ve bought two actual ones from eBay but the prices are massive. Also they are worn out and the checkering on the back is pretty bad. They don’t fit the look of the new builds and won’t even after new bluing. Contact me.
Nate, Happy to help. Please email me at Lastbastionlabs@gmail.com I have some questions and then I can get you a quote. The link below is to my video on cutting steel mainspring housings. ua-cam.com/video/l6ksecCPGr8/v-deo.html
I see you you're using a Tormach, but what tolerances are actually needed for firearm parts, or really just firearm frames? Can .005-.010 inches off still create a functioning part / frame?
The Tormach is capable of holding better than a thou most of the time. I have found that setup is one of the most critical components for accuracy. If you have dreams of machining 1000's of frames, I would get a bigger machine. If you are looking to machine one frame for your self, you can get there with this machine and good set up.
@@LastBastionLabs hmm I heard that mostly what should be concerned about is clearance. And for a frame that would include pins / rails if its a pistol. And supposedly looser tolerances for rail is good. And for pins. Well people drill out pin holes with a hand drill so. Right?
@@GoldenTV3 I have never done a frame or completed an 80/20. When you say "clearance" I'm assuming you mean Z height clearance. The 440 should be sufficient. For hole placement, set up and process are critical. Hole placement is easy, its your ability to drill perpendicular to the work. If your drill tip wanders then the hole placement on the other side will be off and would required increasing the hole size to allow for fit.
can anyone on this video help me find a mill machine which is small enough to fit in my garage
Would you be willing to make a rear sight assembly for a Smith and Wesson Model 29-2 for me? I've been desperately trying to find it!
I have moved and my shop is in kit form right now. I will not be making anything for a while.
@@LastBastionLabs thanks for the reply anyhow!
Make that part only in a magwell
I have a plan for that when I do my 1911 build.
Checked both my 1911s, in 9mm and .45ACP, no mainspring movemwnt at all.
Good to know, thank you for the feedback.
Do you sell the checkered mainspring housing? I want one!
I have recently moved and my shop is in Kit form until I can finish my new shop.
I want tocnc mill a 1911 slide or upper receiver,what is the most affordable cnc mill machine I can purchase,can you suggest one?
I only have experience with Tormach. I would get the most machine you can afford.
The link to Mr.Bensons drawings is not working, any idea where I may find them? Thanks

It worked on my computer.
Damn. Do you sell ? I want a few crosspattern checkered (WWII authentic in appearance) 1911 mainspring housings exactly like your finished part.... I’d like aluminum ones as well......
Yes, I am planning on selling them. I have not be able to get to the range and verify they work. I will let you know when they are ready. Thanks for stopping by the channel.
Timothy Austin yes, I will place orders. I “need” two right now..... just respond here. I’m going to save this video to favorites and liked.
@@LastBastionLabs Notify me when you go public.
@@MaturePatriot roger that!
Could you make a 1911 frame with your setup?
In theory, Yes. But I could buy an 80/20 frame and finish it faster.
I just watched the whole video without understanding any of it....
Can a tormach 700 machine a 1911 frame?
What about the slides?
In theory yes. The 700 machine has a work envelop large enough to do a frame and the slide. Not sure about the Z axis. If you are machining a slide from scratch you may not have enough Z axis to drill the hole for the firing pin. You would have to model the slide and take some measurements.
Which of the tormachs would have enough z axis to do the job completely
@@LastBastionLabs do you think there is a benchtop cnc machine that is capacble of doing the job of completing an entire frame and slide from scratch?
when you say you will have to model the slide and take some measurements,can you elaborate?
@@lance5295 The total z height you need to know would the length of the slid, plus the length of the drill to bore the hole plus the length of the drill chuck. I do not think the 440 will have enough. I'm in the process of moving so my tools and machines are all packed up. You could contact Tormach and ask them.
Good work but takes way to much time
You are right. I will make the next on on my 4 axis.
Careful, a guy went to prison for gunsmithing.
😂😂😂😂😂😂
