- Getting in some more heavy shaping, testing different tool grades and tool grinds to compare results between cuts. The material I used is a 10" block of mild steel. I'm also testing the use of the Noga Mini cool on the shaper.

Back in the day (wails of anticipated horror!) we used a tool very much like the second negative/positive grind you had on the 1" Mo-Max. It was very effective on brass, soft and cast bronze, aluminum, and lower strength steels like MIL-S-871B (Navy) steel plate. Hot rolled steel plate, rounds, and shapes (A36) commonly found in steel yard racks are a stronger. The acute edge angle might be a bit fragile in your application. I suggest you break your tool's keen edge to a 0.005" champher to strengthen it against crumbling.
If I recall correctly, the shaper tool grind we used back before dinosaurs rode skateboards (that was the actual extinction event: Chixilube is a myth of convenience) was 7 degrees side clearance, 10 end clearance, -15 degrees edge rake, 40 degrees top rake, and 0.40 nose radius, edge honed to a bright line champher..
Upvote this guy! Adam needs to see!
Adam,
There is something almost meditative watching the first 4- 5 minutes. This behemoth of a machine ,taking these delicate
cuts off a chunk of steel like it was modeling clay . The same satisfaction a fine furniture maker gets from that last shave with a plane that makes the joint vanish . Stay healthy brother ,
already waiting on your next post .
"let's see how big we can go on this shaper" = Best Quarantine-Era activity/video I've seen thus far. The acoustics on that slow-mo drop is like bells ringing
That is impressive, I am a former truck driver, and found your channel while recovering from a leg amputation. I really like listening to all your explanations and most of all how easy you are at moving and setting things down. If I could ever afford to send you a post to my prosthetic I would love to have you turn a design into what is exposed. It's a titanium piece. I might suggest a set of screens to set up around the shape. It will offer you the ability to move around the machine without that big box to work around and lift up. Yeah you still have to sweep the floor but unrestricted movement and lightweight frames with screen material of some sort seems to be the answer. Good show for tig welding 45's at the corners
There is something oddly satisfying about watching a shaper run. Thank you for taking us along! 👊😉📸
The groan of metal being sheared, and the “tock” of the clapper box...ASMR! 💆♂️⚙️🧠❤️
Especially in SLO-MO. They sound like manly wind chimes at the end.
*(Does Tim Allen grunts)*
The sound of the tool holder clapping back down before the next cut is so soothing
That's very nice video for me. I am from China and I have many old machines for crankshaft produce. Now I am selling CNC machines and sometime I feel the old machine is garbage，but now I feel that I got some golds! Thank you.
Robot toe nail clippings all over the floor
Heavy shaper cuts are really a controlled tool crash. I love it! I could watch a shaper or planer cut for hours. First machinist job I ever had was running a 30’ planer marching press brake and shear tool platens. That was 45 years ago and I’ve missed it ever since.
High school metal shop, I learned skills on machines like these, Logan shaper, Atlas lathes,milling machines stick welding... they sold off all the equipment put computer stations in . Skilled tradesman, machinists ,fabricators,welders are in demand now. Those that can work with their hands will never lack for a job. Thanks for educating .
This is the Abom79 version of whittling. Can't go anywhere, can't do anything, I know, let's whittle. It's hypnotic, somewhat cathartic and fits perfectly with our current situation. Thanks Dr. Booth. :)
every time it takes a pass, it sounds like unrolling some packaging tape. lol
Interesting how the chip gets compressed. It's not as long as the stroke of the cut.
Yup. That's how chip formation works. When a cutting edge is forced through ductile metals a chip of deformed metal is produced curling off the tool as it follow the feed path.
Imagine a coin stack toppled into an overlapping row representing the undisturbed metal to be cut by the passing tool before its deformed into a chip. As the tool passes, the metal shears along descrete planes that slip and realign our metaphorical row of overlapping coins into a stack. Apply a strip of tape up one side of the stack to represent the shiny side of the chip where weakly fused metal holds the slip planes together. The overlapping row of coins is rearranged into a shorter thicker stack and our metaphor is complete.
Watching a shaper work is like watching a fire or bug zapper. You can't hardly take your eyes off it. I have a small 7 " shaper and always think I'm going to get it cutting on a job while I run the mill or lathe but always end up watching the shaper cutting chips. I love them.
Thank you for showing how to grind single bit tools. I set up a fly cutter for the first time last month. After several trips back to the grinder, I was able to get a beautiful glassy smooth cut. I would never have thought a single hand ground bit would preform so well. I like that you show us what dosen't work and how to adjust the geometry to improve the performance.
Yup, no need for introduction, straight to the good stuff!!
Thanks for sharing, Adam.
What a beast! Maybe you could make a wind chime from the chips
I'm not the only one that thinks this is beautyful right?
When abom goes to the store to buy chips, he walks past the lays giggling, he then grabs a bag of whole russet potatoes and says “now these are chips!”
Your close up shots of working machinery are so good I have to wear safety glasses while watching! 🤓
March 29th, 2020 - Florida man injured from rolling his ankle on what he calls "some chips"
Is it just me or are the shots with the camera moving with the shaper the most soothing thing ever?
It's interesting to see how much the chips are compressed. I.e. 10" block, but the chip looks to be about 3-4" long.
Yah i was wondering why does this happen?
@@stevieray667 I think it’s because the metal gets compressed as it’s being cut away.
The Shaper is back. I missed my little buddy. 😂👍👍
With that machine, you need a hardhat with your safety glasses!
Man I like watching that shaper run! Not sure why.....just do! Thx Adam!!!
I started out in machine in the early 60 s,while in hs we went to voc machine shop half days where we would shave v-8 flateheads, to not only to flatten but to up compression,on a shaper, then after a stint in their Navy came home to a tool and die apprenticship,where we used 2 shapers to rough out steels,later we used a planer for bigger jobs, later we acquired a planer mill with 3 heads. What a change in type of work and chip removal. Now retired after 43 years in thei shops,working for 4 different employers, great career, you do great practical videos keep up,goodwork
When the included angle of the clearance and rake
angles become too small
it creates two problems.
It weakens the cutting edge and is more prone
to chip. Second,it doesn't
disperse heat away from
cutting edge as well and
is more prone to burn.
Keep the shear it cuts
smoother with less chatter. A wide or long
cut can bang when it
enters the work .
I am a tool & cutter grinder by trade .
Oh good, new episodes of The Shaper Channel, er, I mean Abom79! Fun to see machines used to their capacity.
That shaper is AWESOME.
I'm just a Maintenance Tech who has a great appreciation for these older machines. The forces exerted, how these machines have held up. Just really cool to see um still being used.
THANKS 👍👍🇺🇸
In the “50” & “60” “s” my dad planed lathes he machined a hydraulic cylinder in the clapper box that lifted the tool on the back stroke, and was able to get a mirror finish on the ways. My brother runs the shop now he put a Bridgeport head on it and cuts keyways in heavy shafts.
HI Adam, regarding the damage to the tool, please take a look at the video starting at approx 18:27.
My (extraordinarily uninformed/uneducated) supposition is that the tool is being damaged on the backstroke as it rubs against the workpiece.
When the tool returns on the backstroke it is rubbing on the workpiece. When the next forward stroke happens you can see that the tool is leaving a wavy/imperfect cut (a horizontal line) in the same section of the tool where the tool was rubbing against the workpiece on the backstroke.
Wow.. them are some serious chips
Crazy to hear that thing grunt like that. Ton of pressure on the work piece! Very cool! Thanks for the video. The difference in the chip coolant running vs no coolant was awesome!
I would like to let you know I really like what you do; I am not a machinist but I do work with tools. You have the art to this science and the science to this art down, and everytime I watch your videos I learn something. Keep it up and thank you.
I love how it sounds like church bells when you drop the chips in slow motion
Thats a big boy chip right there
I am happy seeing at least a few people know how to set up the clapper box correctly. I started off in the machining trade running shapers. We always pointed the chips toward a wall. A 16 inch long cut, 1/2 inch deep at .020 feed in 6150 steel would fill up a catch box very quickly. Had to put a sheet of plywood against the wall as the chips were chipping out a hole in the cement blocks.
Great machine for running contours on stamping die sections. Love your videos. Keep up the good work. PS, I still own three. @ bench top Atlas models and a 16 inch Varnamo made in Sweden.
The slow-mo sounds just WOW!
"Keep em CONTAMINATED right here" I think you meant contained but everyone has the virus on their mind lol
This brings back memories of a "production" shaper I ran at Caterpillar back in the 80's. That machine had two tool heads, a left and right, and a 15' table would move back and forth under the tool heads. The table was magnetic and would hold two bars at a time, one for each head. It typically shaped the width of long bars. Those chips would easily burn into the bottom of your work shoes!
Thank you so much. All these years of watching your videos and I've always wanted to see you pick up some of those shaving so I can see how big they really were. My dreams have came true. Thanks Adam.
Much love from NorCal
Why the hell is it so mesmerizing to watch machining equipment run ! And with that,
I’ll get back to watching this video 😁
I love the sound in the slo-mo.. Back in the 70's the Rex AAA was my go to lathe tool.
I found this relaxing and satisfying 😊 Thanks!
Adam, You should really invite The Slow Mo Guys to your shop. You could probably get some fantastic slow motion action of your machines. I'd watch.
34m05s ... the bells of St. Abom...:)
Other content: Let’s dial in ten thou and see what happens.....
Abom: Lets just take a 1inch skim cut......
There, done and fixed:)
I would love to see this with a FLIR/TIC
ToT just posted a video titled ASMR for machinists. This video could also be called that. Very relaxing.! Surprising how the tools discolored at the cutting edges. Tremendous forces at play. Love the “church bells”.
If you want to get a gauge on how "hard" you're pushing machine - hook up an ammeter/amp-clamp to one of the motor leads. Watch the current as it enters the cut. How close it is to the motor's rated current should give you an idea of the "load".
American Locomotive You are certainly correct! Look at the current when the ram cycles but not cutting vs. taking a heavy cut. That difference gives you an idea of the power (voltage x current = power in watts) required for the cut. Knowing the time to make the cut, one can approximate the energy (watt-seconds or joules) required. Finally, since we know the length of cut, one might be able obtain a reasonable estimate of the cutting tool force. Just a thought. Be well! Gottfried
I just love the sound of those giant chips bouncing off the vice and floor. Sounds like someone dropping a short sections of angle iron.
I could fall asleep to the beautiful sounds of that machine at work.
I don't know why but watching that beast cut is mesmerizing
I need to clean off my shaper and do something with it. Your inspiring me Adam
the sound of the chips in slow motion is like crowbars hitting the floor
oooh, lets take a hunk of steel and make huge chips. I am down with that
Dig that smirky little grin when ya put the cam on the arm :)....A sure sign Adam loves his work! Reminds me the first time I got to use a pipeline welder...that sound literally made me drool. The world needs more people who actually enjoy their work.
That's so calming I could sit and watch that all day. I can't believe how it can cut that deep without snapping of the tool bit. Love it.
This is the new go-to-sleep soundtrack for me...
I still think you should make something out of that block on the shaper, such as a regulation size gaming die (as dice). That would requires lots of 'heavy shaping action'!
11:26 Caught you, you smiled! :)
Thanks so much for what you do for us Adam. Stay safe, stay strong. Peace and love brother.
It's no wonder why you like the shaper. The operation is really neat to watch. The amount of power that has to be transferred into the tool to make that heavy of a cut, and so smoothly, and without breaking anything. It's just neat.
Hey Abom79, when will you show us the flexarm working. Let's tap some holes.
Abom, I really enjoy all of your videos. In watching this one I noticed the tool dragging on every return stroke. I think that if you tilted the clapper box over to left of center rather than having it right of center you'll find that the tool swings out and away from the work on the return stroke. Then the spm cold be increased a little and it would really fly out on the return stroke. Of course your tool alignment would be same as your using now, it just wouldn't drag at all on the backstroke.
Thanks for the feedback it kind of hurt me to see his tool dragging on every backstroke. Yours was the only feedback. Also many people are surprised to learn that the backstroke is faster that the forward stroke. I pointed that out to an old hand who was running a 48 inch shaper. He asked me what I'd been smoking. I had him count the forward strokes and backstrokes during one minute. He couldn't believe it.@@mjm7187
The .500x.030" chips sounded like the shaper was launching big ol' bottle caps, or washers!! That's so awesome!
Not bad. Someday you'll be ripping those 2" 0.030 chips off like Cincinnati had in that one photo. Just need some A12 steel like they had lol.
To prove your table movement theory causing chatter, could you put a toe jack under table whilst taking a heavy cut to see a before and after?
Easier than stripping a machine down.
Also, could you try your LNMX in shaper head as a video clip?
My Cincinnati Heavy duty 24 shaper book shows it cutting a chip .030 feed x 2 inch cut.
Thinking you have lots more capacity in your machine.
I used to use a planer.Same principal but the tool is stationary and the bed moves. You put a small leather strap behind the tool so on the back stroke it flicks under the cutting tool avoiding scrape marks!
One other comment, We always had the vice running parallel to the stroke. Basically 90 degrees from your set up. That would protect the vise in case something went wrong. We also used hold downs to keep the block of steel pushed down against the base of the vise.
I purposely hold large workpieces like this when I can against the jaw to prevent the shaper from pushing it out. I know because if done myself a couple of times. Otherwise, positioningof the vise depends on length of part.
-"Whats the chipload on that tool?"
-"Yes"
I think you'll need heavy equipment to pick up those chips!
Cutting new stairs for the shop!
Nice
Finally some Abom sized chips - looks like I see a little collab project on the bench. Keith Rucker’s stoker engine? Doing some spray weld buildup?
I haven't seen an operational shaper since my apprenticship from mid to late 70's. Is it just me or can anyone else smell the heat in the chips ?
I see "Heavy Shaping Action" and I click on it faster than "Free Toilet Paper Giveaway."
Yeah, i especially miss the old shop videos of the big lathe and mill jobs. So damn entertaining. It's like ASMR for your eyes!
Super fun. I think this is my favorite shaper video so far. Especially liked the dropping of the chips in slow mo
Hey Adam really enjoyed that, I started my apprenticeship in N Ireland in 1965 (James Mackie and sons) and one of the machines I was taught to operate was the shaper as well as lathe milling m/c welding etc.
I am delighted to see you teaching these skills as they are slowly disappearing, you so remind me of me in my early days. RETIRED now but still keep my hand in with a small m/c shop in my garage.
Keep up the great work.
Cheers
where does one even get a cube of steel like that?
Ping Pong
From the shop his brother works at! Adam explains that right at the beginning.
We've all seen them ...now they have a name......the "ABOM CHIP"
Wow, that brought back an old memory, in the 7th grade I had metal shop class as one of my classes and our first project was using a shaping machine to make a hole punch for paper. We formed the body of the punch from a single block of steel, worked pretty well but I have no idea where it went.
Shapers are so satisfying to watch
I love how it sounds like tape peeling
Making piles of robot eyebrows
Just what we need right now! Thanks
Great video Adam. Brings back very old memories. Nothing beats the "Old School" machining ... !! Thanks for sharing.
That ol' girl defines 'cool" ! How many factors come into play when the Shaper is just repeating the cut and yet not one chip lands in the same place?
Some REALLY complicated physics? 🤷🏻♂️
A chip off the old block ;)
I love it!!!! :-)
Another great video Adam! Thanks for sharing. The shaper was the first machine I ever learned to run as an apprentice. I always love seeing these machines work to this day!!
Hey, nice to see "Abom Classic" content on the channel! More of this please! Machining esp. big chip machining!
Pot those chips in resin and make keychains, I'd buy one
Man I almost feel sorry for the workpiece, that looks brutal LOL
Never thought I'd get so much satisfaction from watching a hunk of metal being 'shaved'. Love the slo-mo shots.
The power of that shaper is awesome !! Just imagine how much work and effort and cursing would be involved to take a cold chisel, a 2lb hammer, and then carve off just 1 of those .020 x 7/8 chips ... and it does it like spreading butter on toast.
You have ALL the BEST toys!
ps. listening to the tones from the slow mo drop, those chips are amazingly consistent in how they all deformed during the cuts as well!
can you imagine one of those chips down the front of your shirt?
Lol
You'll be finding chips for years to come. In boxes, under tables.
Don't forget about the soles of your boots
Really nice stuff.
Now those are some abom sized chips!
