Hello 👋 basically with this clamp in the middle and the 4th axis you can do 5 faces operation from one clamp in the vice fixture you have made. Perfect, nearly capability of a 5 axis machine on a 3 axis machine with a clever setup. Keep up making your videos they are great 👍 all the best Danny
Thank you Adam! Just the video I needed! It's almost spooky, I just came in from the lathe, after another unsatisfactory go at turning copper(I'm no machinist), for a glass to metal seal known as Housekeeper. It requires turning copper tubing, to a tapered knifes edge, but it just kept peeling like a banana. Tomorrow I will try to bore the inside to even out the work hardening. Again thank you! Your videos are such a great resource for armatures(like me) that crave technical insight.
Thanks so much for posting your video. I just found your channel and really enjoyed it. I really like how you illustrated the material stress. Thanks so much for sharing the wiggle check that was a great technique for a problem part I got!!! Looking forward to the next one.👍
Fantastic video. Please keep this kind of content coming. I have been interested in making a small dovetail fixture for awhile and haven’t gotten around to it yet.
Well I'm glad I got to see you latest video while it was still up. Idk if its worth it to you to upload to other platforms, if you do anything like the 1911 video in the future, let us know where you have it uploaded and I will add it to my grayjay feed. Would suck to have all the work you put into the video lost to time. Hope it doesn't discourage you from uploading your work in the future. Good luck and happy new year.
Copper only machinist here, sometimes. Copper is so easy to machine , just annoying to drill and turn😂 super gummy, mills beautifully. I make anodes for semiconductor industry, even material removal is the key
Hi Adam, your videos are really informative, I learn something new in every single one. Especially on workholding. Are you running oil, or standard coolant in your Haas?
@@adamthemachinist - What's the actual downside (if any) to running neat cutting oil in a CNC? The old farts I've asked about it in the past all like to go on about it gumming up & requiring far more frequent cleaning. I'm not convinced their tales of doom & gloom reflect badly on the concept, or the state of cutting oils from back in the day.
@@somebodyelse6673 The main downsides are the decreased heat transfer away from the part, slightly less flushing ability from deep features, and the Mrs kicking your teeth out for traipsing neat oil through the house from the garage. None of your handtools will ever rust though!
@@somebodyelse6673 In fact I own an old East German WMW-Heckert toolroom milling machine and the manual states that coolant is undesirable because of corrosion and it calls for using only oil as a cutting fluid. The machine is from the early sixties I think, maybe late fifties.
Really great workflow you have going on there. 5-axis can make for some lazy solutions and before you know it you’re back to 3-4 axis because it costs too much to keep that up. You’d make the most out of one I’m sure.
Adam thank you for the content. I very much appreciate the focus you place on the viewers learning potential thank you for this. I am a self taught fully on youtube. I would appreciate your tips and tricks on checking, calibrating, and getting the highest precision out of your cnc machines. Say if you purchaed a new cnc mill for example, how would you start to tune it in and get tuned in with it? Test parts you would run, measurements you would take, and so on. Would you consider making a video on this ? Thank you again.
One of the best hardware machining videos I have seen in a long time. Wasn't familiar with erowa and was not entirely sure how the angled tabs help keep the jaws from lifting up and still allowing good clamping if the male portion is say a bit undersized? I built a dovetail for aluminum machining to get all around the parts, works but the tab angles up. I've seen the 5th axis and raptor guys using some kind of dowel pins or t-slot tracks to hold it in place but like the idea of the angle tabs better. Machining another couple vises in the near future and luckily I don't have to make it zero point indexable but it needs to be about 4-5" tall because its on a 4th axis trunnion.
You do need to be pretty consistent with the width of dovetails. as the clamp tightens it bears down on the angled slope in the fixture as well, removing any play in the system
Have you considered annealing the work hardened copper that you purchase? It only needs to be heated to 500C and then allowed to cool slowly. To prevent oxidation, you can wrap is stainless steel foil. From the size of the parts in the video, a knife forge will work quite well. Just need to get one with doors. Many handheld electric test meters are available that can use a type K thermocouple for temperature monitoring.
A lot of the copper I deal with does get annealed and sometimes even cryogenically treated, just depends on what the customer will pay for or has time for. It’s a vast improvement but doesn’t totally eliminate the problem.
Liking the use of Erowa on this, used the system a few times in the past and highly rate it for repeatability. Only drawback is the cost of the pallets 🤮 It's funny you show dovetails I was only this week preaching the benefits for turning to colleagues where stock material is limited
Something I've always wondered - how did you deal with the power situation in your shop? You work in your garage on your house property still correct? Do you just use rotary phase converters? Get the power company to augment? 220v VFDs? I'm struggling with small machines because of a residential situation and haven't come down on the best power solution. Thanks! Love how youve built your business. It's inspiring.
Originally the shop was built around single phase equivalent, the haas and kaeser compressor are factory single phase and the manual grinder uses a vfd . The later equipment is three phase and I use phase perfect digital phase conversion for that
That’s what does the actual locating. the rectangle slot are a bit under sized, when clamped the plate flexes away from the blades on the receiver/chuck . So you end up with zero looseness on the locators . Something like a dowel pin and bore needs a few tenths difference in size to come apart easily . So you have a balance between accuracy and ease of removal . The stamped plates are the best of both worlds
Hi Adam! I noticed that you haven't posted anything in six months. Hopefully the realities of life hasn't been treating you badly. I, for one, have been missing you. Assuming you still find joy in it, I hope you'll get back to making educational and stimulating content soon again. All the best! //Joel
@@adamthemachinist I'm happy to hear you're doing well! When the wife, dog, workshop, and bottom line are all cared for, don't forget to think of yourself before thinking of us. If and when you do release something, I will be watching it. Take care! :)
Is the piece held only on the dovetail or is it held on the dovetail and on the uppersurface of the clamp? If so the position of the dovetail will have to be verry accurate. I am not using a dovetail clamping yet. But i would try it. What to look for to do this?
The dovetail and the upper flat part of the fixture are what make contact , the center flat section has a small amount of gap to ensure the widest part of the fixture is touching the stock. The dovetail size can vary a bit since the clamps can accommodate the size difference. I would look at commercial options like raptor workholding or 5th axis to get a deeper understanding
Hi Adam, such a great video. Its so great to be able to see your setups and your approaches to making parts and its not lost on me how much extra work goes into this for you. The subtleties I can pick up from these I just gold. I was left with a question after this video. I understand not biting onto the actual stock with the lang vise, but couldn't you use the dovetail feature of the lang gripper jaws on a similarly thick dovetail cut into the bottom of the copper? They have a 45° built into them right? I get this might be more bulky than the dovetail fixture you made, but I was curious. I've done this in the past and it 'seems' to work well, but can't really back it up with any data. I usually grip on dovetails that are 2mm tall, but don't see why 1.5mm couldn't work?
That thought crossed my mind . Ultimately another part not shown is what pushed me to a dedicated fixture . It’s much smaller and the compact dovetail fixture is much easier to work around than the somewhat bulky Lang
I worked in an aerospace machine shop for a while and we were constantly fighting internal stresses. We would do 5 5axis set ups to rough, relocate, then finish machine. I'm curious if you have ever had to drill very small holes in copper before? I have a project coming up where I need to drill some .005-.007" holes in copper alloy. I'm wondering if you have any words of wisdom?
I used to do quiet a bit of small hole work in copper , but it was .02 4xD. I had a lot of things going my on that project with running cutting oil and have lots of Rpms at my disposal. The drills came from Mikron , crazy drill line . The feed was quiet impressive for such a small tool , .0024 per rev. Unfortunately .005 diameter is a very different story, good luck
Hey adam, I usually machine parts out of duplex and super duplex, but every time I face them, these parts want to bow the other way around. They don't bow up as you have shown in the example with rubber bands, instead they "bend" up (or bow down). Can internal stresses want to stretch the material, instead of compress it? Have you encountered this problem? Cheers
I’ve had the opposite reaction like you speak of, and many other hard to predict bow and warping problems . Sometimes the the material can get a little bit of work hardening that contributes to odd things happening. Or maybe there’s a hit to much clamp pressure that overwhelms the part as it gets thinned out from machining .We apply best practices like stress relieving and sound machining strategies, but at the end of the day work that wants to warp is still a challenge.
Hi Adam, I was curious what you are using for coolant? You once mentioned it years ago when nycnc did a shop tour but I couldn’t quite make out what you said in the video.
@@andrewh2341 well the haas is a grease machine , but it seldom cause issue even in way oil machines . Over time you carry out small amounts of oil on chips and tools. So the addition of new oil is generally faster than the way lube is coming in. For certain cases were you need a very specific lube and it can’t gradually change, you can find cutting oil manufacturers that offer compatible way lubes that don’t pollute the cutting oil
I don't do much copper. So you are saying the residual stress in copper is only on the skin and that the core is free of it? It would be worth pointing out that other materials like heat treated aluminum have stresses all the way to the core so that "skinning" it won't get rid of the stresses in those cases ex: 6061 T6. The stronger the material is, like 7075, the more residual stress it can sustain.
It’s has some stress to the core, but the bulk is in the first 1/8 inch or less. Of course it can also work harden and do some odd things with stress that way to . If lead time allows I still like to stress relief . But roughing five sides then finishing is a nice alternative
I’m not doubting your fixturing skills here, but why not just buy a blank Erowa pallet and then drill, tap, and pin it for one of those Raptor clamps? They are expensive but really nicely machined and (best of all) premade.
That is a fair point to make. Most cases it makes sense for me to buy if its available. Not just from a cost perspective but time. But sometimes I like hanging out in my shop making things that I've designed. Work isn't scheduled for Saturdays, that's for personal projects. So if a fixture that might cost almost 1k to buy can be made on a Saturday , and I enjoy myself while doing it , why not just make it and save the money? Plus it makes easy video content since there aren't any NDAs
Yes, I have to ride my volume slider. Opening shot is too low, then it normalizes for the rest of the video. I figure he'll get it sooner or later. The content is good enough to warrant dealing with the minor issues like this, like the Dan Gelbart videos.
Yo, buddy, i`ve seen you post a video but some few hours ago... Did you have to delete it due to weapons content or wha`? I didn`t see it yet, had it opened in a new tab, but i fell asleep before i got to that tab, now i see the tab just reload from your vid to youtube homepage with no trace of the video on your channel... Dafuq? Sorry for posting here on an unrelated video, but i can`t seem to find any of your contacts, and it`s easy enough to delete this comment at a later date...
@@adamthemachinist fucking hell mate... It`s a bitch ain`t it... Are you gonna edit the video down, cut the ``offending`` parts out and publish it again or are you unwilling to risk the bother and potential shit from the reptilian overlords? I guess you probably showed too much details, rendering it a ``how to make`` video, which likely wasn`t all that fine with the regulations... I know that Stefan has his own 1911 baby replica series, i never watched it really, but i know it`s there, now is that a weapon? Not sure, i don`t know does it have the ability to fire a round if fed one, but that`s my guess... Tho, i think there is more than enough videos with very similar operations depicted, from rifling to all the other things, so i can`t say, i usually don`t watch weapons stuff, but i do love me the sight of a nice 1911... They really are beautiful in their own way... Feel bad for ya mate, having the latest video torn down after 8 months of silence... What a damn bitch of a situation... All the best my dude, and warmest regards! Steuss
I used to use 3R chucks a lot. I had a mini KURT vise on a pallet, and you could have it on the machine and indicated in seconds. I love the mini pallet you make, those are works of art.

It’s has some stress to the core, but the bulk is in the first 1/8 inch or less. Of course it can also work harden and do some odd things with stress that way to . If lead time allows I still like to stress relief . But roughing five sides then finishing is a nice alternative
By starting the video my first impression was that you were in a hospital bed...thank God, it's just my imagination 😊
I’m not doubting your fixturing skills here, but why not just buy a blank Erowa pallet and then drill, tap, and pin it for one of those Raptor clamps? They are expensive but really nicely machined and (best of all) premade.
That is a fair point to make. Most cases it makes sense for me to buy if its available. Not just from a cost perspective but time. But sometimes I like hanging out in my shop making things that I've designed. Work isn't scheduled for Saturdays, that's for personal projects. So if a fixture that might cost almost 1k to buy can be made on a Saturday , and I enjoy myself while doing it , why not just make it and save the money? Plus it makes easy video content since there aren't any NDAs
at the minute 3:10 which program you are using ? Solidworks ?
Fusion 360
I can't believe the RUclips snowflakes took down your 1911 video, glad I got to watch it.
Well...... It was good while it lasted 😂
👍👍
Did you ever say what programing software you were using for your CNC machines? Charles
Fusion 360

What's up, how is business doing?
Pretty pleased with sales still. Not sure if there will be any big purchases in 2023. Just saving money till the next big fork in the road
@@adamthemachinist glad to hear that. Keep it up.
your voice levels are to low
its hard to hear you on max volume
Sounds fine to me.
Yes, I have to ride my volume slider. Opening shot is too low, then it normalizes for the rest of the video. I figure he'll get it sooner or later. The content is good enough to warrant dealing with the minor issues like this, like the Dan Gelbart videos.
Yo, buddy, i`ve seen you post a video but some few hours ago... Did you have to delete it due to weapons content or wha`? I didn`t see it yet, had it opened in a new tab, but i fell asleep before i got to that tab, now i see the tab just reload from your vid to youtube homepage with no trace of the video on your channel... Dafuq? Sorry for posting here on an unrelated video, but i can`t seem to find any of your contacts, and it`s easy enough to delete this comment at a later date...
It was taken down by you tube for not meeting policies regarding firearms
@@adamthemachinist fucking hell mate... It`s a bitch ain`t it... Are you gonna edit the video down, cut the ``offending`` parts out and publish it again or are you unwilling to risk the bother and potential shit from the reptilian overlords? I guess you probably showed too much details, rendering it a ``how to make`` video, which likely wasn`t all that fine with the regulations... I know that Stefan has his own 1911 baby replica series, i never watched it really, but i know it`s there, now is that a weapon? Not sure, i don`t know does it have the ability to fire a round if fed one, but that`s my guess... Tho, i think there is more than enough videos with very similar operations depicted, from rifling to all the other things, so i can`t say, i usually don`t watch weapons stuff, but i do love me the sight of a nice 1911... They really are beautiful in their own way...
Feel bad for ya mate, having the latest video torn down after 8 months of silence... What a damn bitch of a situation...
All the best my dude, and warmest regards!
Steuss
@@adamthemachinist Any chance you could post it elsewhere? Camillo is not the only one that missed out on watching it!
I used to use 3R chucks a lot. I had a mini KURT vise on a pallet, and you could have it on the machine and indicated in seconds. I love the mini pallet you make, those are works of art.
the sound of z axis of your milling machine is terrible.
