Sorry about the last video getting removed. I was unaware that TH-cam had policies it was in violation of. Before it was removed I received a lot of feedback about the shaping operations and people were curious to know more. Hope this gives some context to my way of thinking. Obviously micro shaping is limited in the part/feature geometry it can handle, view it as one more tool in the box for tackling tough parts. -Adam
So I saw the post Spencer webb made about the video getting taken down and your comment with the google docs link. I took a screenshot to try it later but by the time I did it wasn’t working and his post was gone. Any chance of still being able to watch it somehow cause I wasn’t able to watch it
It sucks, it was such a fantastic video as well. I love firearms and machining, and would love to get into the latter as a hobby. I think the algorithm recommended that video to me because I was watching Forgotten Weapons on here. I then proceeded to watch everything on this channel. Usually the machinist channels I watch are trying to get parts within a thousands, your channel showed me that you can move a digit over consistently. It's such good content too, and the way you communicate and present ideas is top notch. I'm glad that video getting removed didn't discourage you from making content!
I've got no real interest in gunsmithing, and if I did, I'd never collect the skills and machinery to reproduce what you'd made. The workholding/ fixturing display was awe-inspiring though.
I love how I always learn something useful (or many things for that matter) from your videos. It never would have occurred to me to use the SG like that. Also pretty interesting to hear all of the factors that make micro-milling disadvantageous since that applies to tight tolerances on larger scales as well. Thanks, Adam!
From your appearance in a NYC CNC shop tour years ago, through your own shop videos, I've been consistently floored by your know-how. The recent videos where you go into detailed explanations are a real treat to watch. I'm glad to have seen the 1911 video before the takedown. That was a tour de force. Thanks so much for sharing the knowledge!
Whoa, what the heck? That 1911 video had so much content - it was like an hour long. What a loss. Did it get flagged or something? Edit: oh, I see Adam's comment about the takedown now.
The results speak for themselves! This is certainly a niche but clearly a relevant one, and I put it to you that vintage shapers with modern controls can still be relevant.
I picked up a small shaper a few years ago, mostly because I thought it would be a neat machine, and a lot of fun to use (which it definitely is). Adding a DRO and a quick-change toolpost has made it a seriously useful tool in my shop.
I used the cnc mill as a shaper. Was adding tooling to the underside of the head that was not finish machined. Mounted a cutter in the vise, and ran gcode to shape that area flat. Plus the added benefit that cleared area was square to the table travel. Worked well.
Fantastic example of precise and creative machining. Thank you! Years ago, my Dad taught me how to shape keyways on shafts in a lathe, because that's all he had, basically same thing as your process. Your approach is impressive ,fast, and much better for small precise features.
This is super cool, Adam! It's incredibly fascinating to me how machining methods can become outdated, but are never obsolete. Sometimes, there's just no better way. I hope you make a clapper for the manual method. I would love to see what you come up with.
Thanks so much for sharing creative solutions and setups. I’ll probably never even use a surface grinder but it’s great to be primed for clever uses of what you have
I love these videos! The past few years I've been having the urge to open my own little job shop. The work itself doesn't frighten me, I actually love the learning process of a new challenge. Learning how to budget myself and keeping things not only as efficient as possible but also cheaper is a skill set entirely in its self. You're showing techniques that successfully do that WHILE making parts and features that otherwise would be a nightmare for a lot of us. Shapers are said to not make any money, are slow and only good at one thing. You just proved that wrong as long as it's applied correctly. These lessons are invaluable! Thank you!
Shame your last video got taken down, I only wanted it to be longer! Also love the micro shots in this vid, would love to see some more of that on future projects
Hi Adam. Happy new year from Amsterdam 🇳🇱. Would love to see more videos. Not only do I enjoy them but it’s usually something I haven’t seen before also. Thank you for making them, they’re much appreciated.
I do a lot of micro milling in PEEK used for biological research and have played with shaping in the mill for fluid paths with very specific floor geometry. Unfortunately I don’t have a lot of time to play so it goes in fits and starts. I got kinda jammed up with the M code for spindle orientation and my CAM package. I just had a part come in with a 0.030" slot in it that I would have to mill from both sides because it’s so deep and I’m sure I’d break a few of those endmills. The cost really does add up. I’m inspired to try it your way in my Prototrak mill. I just need a way to indicate in the cutter. First tho I’m going to talk to the just out of college ME and find out why the slot is so small or if it’s something I can just cut by hand with a jewelers saw
Just started watching your videos and have a tip for shaping on the lathe. When pushing your tool use the tail stock to help push the carriage it really helped eliminate deflection.
Man I just saw this in my feed and remembered that I wanted to finish watching your last video and was confused I couldn’t find it 😢 What I saw though was absolutely fantastic. Looking forward to this one!
Groovy! :-) Beautiful results from a very interesting process. I especially liked the remnants of the sharpie marks on the peaks between the grooves -- at first I wasn't sure what I was seeing, and then you mentioned what it was. Just very nice; thanks for sharing this!
That's clever. I've never had to machine features quite that small so it would never have occurred to me to use a grinder as a micro shaper. Though I think I've seen a video of a guy who had a tool that was used to create a patterned surface that was essentially a freely turning off-center single point tool that was used in a CNC mill to do something similar to what your doing here by dragging it along a curved path.
Good video thank you I did see your last video also. People all seem to try to go high-tech all the time sometimes there’s a low tech solution to the same problem We did something like that for spacecraft antenna. It was copper plated onto fiberglass sheets, and had to be cutting the notches. And we used a hand block plane there’s a full-blown machine shop.
This exact thing has been floating around my head for ages, with no way of testing it. And all the people I talked to about it were at best "myehh I suppose it could work.." THANK YOU for allowing my brain stop pulling on that thread. I was a bald hair's breath from making a shaper out of a pick & place machine. 😅
This could be useful for putting vents in injection moulds, especially the really shallow ones that liquid silicone rubber moulds require. Thanks for sharing!
Adam, You are inspiring. I do enjoy the ways that you go about your work, and are able to explain everything involved. It is a shame that today’s educational system, only wants athletes and college graduates. I believe it was Henry Ford that stated, continuing to do what you always did, will get you what you always got. You do not seem to be bound by the safety of repetitions. Today’s technology has driven an ever tightening of tolerances and delivery times. I thank you again for the tool room school room.
This is something i haven't thought about.. I could make a Cutter holder on my CNC Mill, and just write a parametric program to do some shaping.. Cool!
Something I think that the hobby shop could benefit from a lot is actually remembering what a shaper is and that you can actually get a lot done with one😊
Hi Adam, nice video again. Just want to mention that the audio when you are talking on camera is a bit quiet, it sounds like the camera mic isn't picking you up super well. Not sure what could be done other than a different mic. Would love to chip in a few bucks to help make that happen, help folks hear those segments a bit better.
It’s not crazy if it works. Using the machine control to emulate the function of a clapper is kind of hilarious. That’s a lot of computing and control to emulate what used to be achieved with a hinge and a rigid stop! It makes perfect sense it’s just funny.😂 Thanks for sharing.
that comment about a lot of technology replacing a very basic mechanism is a discussion I have a lot. Was chatting with a guy that does jig grinding in a linear motor cnc mill and a manual moore. The cnc is amazingly capable, but the number of very expense components needed to do what a few bearings and solenoid do is interesting.
If one has a decent spindle on a CNC mill, then one could even do fancy spirals and such. Just need very little backlash on that spindle, or direct drive or something similar. Effectively CNC carving of metal at that point... But yes, shaping does have a place in the industry for some applications.
Watching your full videos as they come out now I completely missed the micro shaping action Kinda reminds me of the grooving machines watch makers use could the cnc wiggle in a wave as it feeds across ~ish.
I've done CNC shaping on very fine heatsinks or similarly deep slotting. I can get a lot more carbide in with a flat blade than a 1/16" 15-18x reach endmill. Just on two parts I was able to save about 3 days of spindle time. Redline on an air cooled 12k Haas spindle for that amount of time didn't sound appealing to me. Couldn't fit a slitting saw down in a pocket or up against other features. Sorry about that last video, that was very impressive work.
Really interesting video, and you clearly laid out the use case for what is by-and-large a forgotten machining technique. I have some notes about the audio in this video: The voiceover was totally acceptable and easy to listen to. The audio that you recorded with the built-in microphone of your camera during the piece-to-camera portions of the video was extremely quiet, and the piece-to-camera at the end of the video contains a fair number of clicking noises that were made by you putting stuff onto the table where your camera was resting. Both of those things can be very easily fixed with free software like Audacity, and if you don't like cutting popping noises out of the audio by hand, just set a rag on the table under the items you want to showcase.
Great info, thanks for sharing Adam! Is the table drive on your grinder gear rack or cable driven? My Harig is a cable drive, and just wondering if the cutting forces would cause slippage on a cable drive?
You mentioned sometimes you need the flat bottoms shaping offers for sealing applications, apart from those, with is this type of grooving used for? seems like a neat cosmetic surface finish :)
Hi, great video as allways! I'm wandering if you tested the upper limit of the material hardness you can shape with micrograin carbide before you chip the tool starting the cut. Cheers!
I got up to 44rc and the tool was holding up , but chip breaking and a very fine burr are a bit of an issue now. I’ll dabble with tool geometry some and see if I can shake out an improvement.
We still use these in India for making large straight cut gears or cogs. Hss is a lot cheaper than carbide inserts to the point that we still lathe with hss.
Ahh, thank you for this video. I definitely fell into the trap of pushing out old methodologies from my head in favor of newer ones. eg. Ultrasonic Elliptical vibration cutting watch?v=CG6O11JPHnA. Could have a use for this sooner than I thought. Deep and narrow grooves, almost 60:1 in non-conductive material. Lapped slitting saws have been... so so.
Any chance you could post the 1911 video to another platform? I got to watch it, but really wanted to share it with other machinist friends. It really is a tragic loss and would hate it to be gone forever.
just a way to mount the cutting tool to the spindle area of the grinder. The erowa systems is me a being a bit fancy, but any method of securing the cutter to the machine is fine. The cutter that did that was lapped micro grain carbide
Very interesting process. Can the cutter stop in the material or does it have to exit the part? There are very niche refrigerant evaporators that use expansion channels that are etched with lithography process, this seems like it could produce similar channels much easier.
I'm really glad I got the chance to watch it first. Sorry they pulled it on you. Maybe repost to a more friendly platform so the world doesn't lose out.
Hey Adam, thanks for showing another interesting technique. That slotting tool is just insane... Is there any reason why you chose the grinder over your Mori mill as a shaper? I imagine that would mean less setup effort and benefit from flood cooling, but I am sure you had good reasons not going that route.
The Mori has a hsk32E spindle . That spindle doesn’t use drive dogs so the tool would have the same rotational clocking between tool changes. Not a huge a deal to clock it in each time , but it’s much simpler tossing a bar of carbide into a erowa holder and it’s already lined up. I also thought the hydro dynamic ways of the grinder would yield a smoother finish
@@adamthemachinist Ah, yes thats quite understandable. Thanks for the explanation! I didn't think much about the spindle interface, although you talked about that before and how expensive and hard to get the tool holders were. Regarding the setup time I was mostly refering to the pulling of the grinder spindle and mounting the Erowa chuck in the first place. Once that's done, I am all with you of course.
Could you please give some more insights into what Erowa chuck I should purchase for a vertical machining center? I want to get a "ITS 100" sized base that accepts both sizes. Is the pneumatic release feature worth it? or should I use the lever actuated. I like the idea of the pneumatic operated because it can air purge the seating surfaces of contaminants. I am planning to buy an budget model "Erowa Compatible" chuck. What should I look for in my first Erowa chuck purchase?
The pneumatic system are a tiny bit more accurate , and very nice when changing a lot of pallets per day. The air purge isn't something I use. Having the door open, it tends to blow cutting oil mist all over the shop. Makes sense for a closed off pallet robot but its not fun having your face above the purge vents. Instead I just wipe the reference spots off with my finger. Which ever way you start out, you'll probably see the benefit and have additional chucks at some point. The lever style is very handy for indexers and small setups and I doubt you kick yourself for having on around
Hey Adam, I would be 'very' glad to be able to purchase the 1911 build video. You're method( with the surface grinder) and artful angle-shots, graphics sold me on purchasing a surface grinder ( a subject I'd love to discuss) later. If possible of purchase let know here. Thanks, great channel.

I’m so used to seeing A. Booth making giant chips at .100” depth of cut it really tickled me to see how precise you can be.

That is a very smart way to true up that surface
Shame the previous vid has gone, glad I watched it.
Shaping on the surface grinder is something I hadn't thought of but I can see it works well.
Absolutely love seeing the optical effects @8:00 - nice work!
This is a fantastic use of the tools available in your shop. Very nice results.

Love listening to people with fine knowledge and the ability to convey it.
Fascinating study of a neat process! So sad Your last video got removed, it was a masterpiece..
I love the content You're making!
That was interesting to see. Thank you for sharing. I can certainly see how this can be useful from time to time.
What a wonderful, creative approach to what could be a very problematic project!
I love it!
Thanks for this 😊
Wow, I had never even thought to use my CNC for shaping! Fantastic. And the close up footage is so good and helpful.
the removed video was excellent from at tool makers perspective. Its unfortunate the content is not acceptable. Would like a way to watch it again.

We did something like that for spacecraft antenna. It was copper plated onto fiberglass sheets, and had to be cutting the notches. And we used a hand block plane there’s a full-blown machine shop.
Epic. Thankyou for expanding my mind
Great info Adam thanks you
Nice application....! Thanks for sharing!!!
This exact thing has been floating around my head for ages, with no way of testing it. And all the people I talked to about it were at best "myehh I suppose it could work.."
THANK YOU for allowing my brain stop pulling on that thread. I was a bald hair's breath from making a shaper out of a pick & place machine. 😅
I spent 20 years machining normal/large parts and never really paid much mind to these micro-scale processes. Fascinating stuff.
I think you have convinced me to get a surface grinder ;).
You should reach out to forgotten weapons and see if Ian could put it on his channel, that video was awesome!
This could be useful for putting vents in injection moulds, especially the really shallow ones that liquid silicone rubber moulds require. Thanks for sharing!

Every time I watch a shaper video I wonder if it can be adapted to CNC and shrunken to fit on a bench, but I didn't know who to ask. Now I know!
Great info, thanks for sharing Adam! Is the table drive on your grinder gear rack or cable driven? My Harig is a cable drive, and just wondering if the cutting forces would cause slippage on a cable drive?
using small depth of cut i don't imagine the forces would be higher than when you are taking a 15 tenths depth of cut with the grinding wheel
The Parker’s use a steel tape band to drive the table. It’s secured to the hand wheel so slippage isn’t a issue
Shame that your last video got the zapped, it was great. This is a super interesting process, thanks again for sharing.
You mentioned sometimes you need the flat bottoms shaping offers for sealing applications, apart from those, with is this type of grooving used for? seems like a neat cosmetic surface finish :)
One customer aligns some very small strands with the grooves I produce for them. Another does some small fluid work.
Hi, great video as allways! I'm wandering if you tested the upper limit of the material hardness you can shape with micrograin carbide before you chip the tool starting the cut. Cheers!
I got up to 44rc and the tool was holding up , but chip breaking and a very fine burr are a bit of an issue now. I’ll dabble with tool geometry some and see if I can shake out an improvement.
Looks like ornamental lathe work to me. Guilloche as some crazy fine detail.
Great modern application of an old method!
I'm curious what are these types of products used for?
absolutely genius
Very cool!
We still use these in India for making large straight cut gears or cogs. Hss is a lot cheaper than carbide inserts to the point that we still lathe with hss.
Ahh, thank you for this video. I definitely fell into the trap of pushing out old methodologies from my head in favor of newer ones. eg. Ultrasonic Elliptical vibration cutting watch?v=CG6O11JPHnA. Could have a use for this sooner than I thought. Deep and narrow grooves, almost 60:1 in non-conductive material. Lapped slitting saws have been... so so.
Something people also forget is you can use your VMC as a vertical broach to avoid another set up or don't have an EDM.
Any chance you could post the 1911 video to another platform? I got to watch it, but really wanted to share it with other machinist friends. It really is a tragic loss and would hate it to be gone forever.
Wow that view of the surface catching the light... I'm convinced -- what does it take to do this setup?
just a way to mount the cutting tool to the spindle area of the grinder. The erowa systems is me a being a bit fancy, but any method of securing the cutter to the machine is fine. The cutter that did that was lapped micro grain carbide
Very interesting process. Can the cutter stop in the material or does it have to exit the part? There are very niche refrigerant evaporators that use expansion channels that are etched with lithography process, this seems like it could produce similar channels much easier.
you can exit and enter mid way but you need the CNC to do it and have it gradually ramp into the cut and ramp out
Adam, On a different subject, did TH-cam take down your recent 1911 video? I found it incredibly interesting.
Keep up the good work!
Scott
I failed to read TH-cam’s rules before posting that . Videos showing how to make firearms violate their policies and it was removed.
I'm really glad I got the chance to watch it first. Sorry they pulled it on you. Maybe repost to a more friendly platform so the world doesn't lose out.
TH-cam got woke, let them go broke!
Hey Adam, thanks for showing another interesting technique. That slotting tool is just insane...
Is there any reason why you chose the grinder over your Mori mill as a shaper? I imagine that would mean less setup effort and benefit from flood cooling, but I am sure you had good reasons not going that route.
The Mori has a hsk32E spindle . That spindle doesn’t use drive dogs so the tool would have the same rotational clocking between tool changes. Not a huge a deal to clock it in each time , but it’s much simpler tossing a bar of carbide into a erowa holder and it’s already lined up. I also thought the hydro dynamic ways of the grinder would yield a smoother finish
@@adamthemachinist Ah, yes thats quite understandable. Thanks for the explanation!
I didn't think much about the spindle interface, although you talked about that before and how expensive and hard to get the tool holders were. Regarding the setup time I was mostly refering to the pulling of the grinder spindle and mounting the Erowa chuck in the first place. Once that's done, I am all with you of course.
Some if that also sounds like a candidate for horizontal mill with a fly cutter.
Old machining techniques are not dead
Could you please give some more insights into what Erowa chuck I should purchase for a vertical machining center? I want to get a "ITS 100" sized base that accepts both sizes. Is the pneumatic release feature worth it? or should I use the lever actuated. I like the idea of the pneumatic operated because it can air purge the seating surfaces of contaminants. I am planning to buy an budget model "Erowa Compatible" chuck. What should I look for in my first Erowa chuck purchase?
The pneumatic system are a tiny bit more accurate , and very nice when changing a lot of pallets per day. The air purge isn't something I use. Having the door open, it tends to blow cutting oil mist all over the shop. Makes sense for a closed off pallet robot but its not fun having your face above the purge vents. Instead I just wipe the reference spots off with my finger.
Which ever way you start out, you'll probably see the benefit and have additional chucks at some point. The lever style is very handy for indexers and small setups and I doubt you kick yourself for having on around
Hey Adam, I would be 'very' glad to be able to purchase the 1911 build video. You're method( with the surface grinder) and artful angle-shots, graphics sold me on purchasing a surface grinder ( a subject I'd love to discuss) later. If possible of purchase let know here. Thanks, great channel.
It’s for free over on my patreon of the same channel name
@@adamthemachinist Thanks Adam.
