Hardtail Vise Build Ep.18: Swivel Base Counterbore
Вставка
- Опубліковано 12 лют 2024
- The final machined surface for the swivel base I wanted to pull off on the cnc mill. With Fusion 360 I used a 2D Bore cycle to quickly and easily milled the angular wall of the counterbore and cleaned up the bottom face to the spec needed. With the bottom face machined the base now has the proper clearance to pivot on the swivel bolt.

There is this old German proverb: only those who do not work make no mistakes. Keep it up Adam, great journey.
Only, if you were a youngster starting out as a CNC operator, cutting out mistakes and machine crashes is very high on the agenda, cos getting replaced by the next youngster waiting in line to take your place is only an easy decision away.
@@james-ew7kl Depends on the employer. I have a friend that forgot to turn on the cooling for a $1M computer and it melted down. He went in to his boss's office to tender his resignation. The boss said - you can't quit now, I just paid $1M to train you! I'm sure you'll never make that mistake again. Now get back to work!
I didn't know it was an old proverb, but I've always said if you never mess up, you ain't going much.
Doing much
I hear that preverb after a crash, luckily tiny crashes - some mills/drills/chamfers because of not setting Work Z height
I know plenty of people only like when use old iron, but when you explain your process and why your using CNC, it's just as enjoyable.
Practice pieces are important. Often the difference between good and better is the practice piece that never got out of the shed.
I haven't been a CNC machinist for a couple of years now, but I have over 10 years of experience doing it. One thing I learned was to always, always set a chamfer tool high and readjust a few times to get the perfect dimension.
Yep. Especially on a one-off. 13 years of CNC machining here.
That may have resulted in a .5 chamfer instead of a .005 chamfer in this case.
"May all your 'learning experiences' be covered by later assemblies" - I heard that one when I first started engineering
My wife is laughing in the background. She doesn't watch the videos but hears it while I am watching. She figures that little error is going to keep you awake, Adam. She's married to a woodturner with the same mindset, so she knows. I love that part of how you do things - the insistence on excellence and attention to the aesthetics, even if the part cannot be seen.
I think it’s so cool that you’re learning all this new stuff. We should always be learning and pushing ourselves in our professions and keep striving to do better. There’s a bad stigma or stereotype in the trades where the more “old school” types would scoff at CNC or designing using the computer. I’m just glad that you seem to be forever a student of your trade.
If you aren’t making mistakes, you aren’t learning.
Still was a really nice finish overall.
The precise and almost inhuman helical cutting down to an exact size, all done by programming learnt by yourself; is proof indeed that you are on the road to mastering yet another skill.
theres no "almost" about it, its done entirely by machine and is literally inhuman
These videos of yours has taught me so much about how to be a machinist you cant go wrong with a shop lesson from Adam Booth!
Nobody will ever see that chamfer, but you know it's there. That kind of stuff drives me crazy too.
I wonder in 100 years when someone takes this apart if they’ll realize how unique having these areas machined is.
Hey, Adam, no worries. Practicing new processes on a casting with no redo possible takes guts. You're doing great.
Adam, you're attention to detail and the little personal touches like this project is why I love your videos. Keep it up man
Exactly, the details on the bottom of the base that no one will ever see!
In this country we say he who never makes a mistake, never fucking does anything. we build our success on top of our failures. keep on truckin Adam you’re on a good path.
Hey Abom. Brit here, learning Fusion 360 myself for making 3D prints from great UA-camrs just like you, making random things for friends, Eventually I hope to get into engineering with that skillset. Thanks for another upload! No projects too small.
One step at a time Adam. Your progress is amazing.
Adam, there is no better teacher than failure. Glad the part looks beautiful and will function 100% fine even with a chamfer 10x deeper than intended.
Adam, longtime viewer and sub. I have no metal working tools. I am a, cut twice measure with my eyes closed kinda woodworker.. My boxes usually have 3 sides... But I love to watch craftsmen ( and Women...) using their craft and skill! The exponential steps in Video quality and the refined content you and Abby ( both in shop and in the wilds...) have produced over the years is simply amazing! I love watching your craftsmanship... But for this post, I wanted to applaud your learning and application of technologies both in the tool room and in video production! I truly have enjoyed being on this journey with you guys!!
Adam, I almost jumper out of my chair when the chamfer tool took that big bite! I remembered you saying the chamfer would be .010.
haha. What a spoiler...I read your comment before it happened.
Me too, i was like " looking good, looking good, here comes the chamfer.... Woah..." Hehe
I thought at first it was intentional and i was thinking that is a mighty wide chamfer but then realised it was a mistake. At least it wasn't like twice that width where it was wider than the bolt.
Other than being esthetically too large, it has no impact on the functioning so it's not that big a deal. We all learn from mistakes.
Messed up a chamfer on a part I spent many hours on, or to be specific two parts because I machined a hole for the cable in the split. The gromet almost covers it but that one will haunt me😅 I feel and recognize the disbelief when you hear it.
Always a learning curve to anything. So many things that can be missed. All part of the learning process. Thanks for sharing.
Trouble with those CNCs is they do exactly what you tell them to do! 😜
Almost everyone who works around machine tools has heard this one. Only people who frequently work with programming tool paths and run the machines themselves really get just how much anxiety those words hold. When you know how bad you can ball up any machine... you respect the process a lot more.
Not always, sonetimes there are pesky coding that prevents ypu doing what you want, like running the machine trough a wall 😂
Keep up the fine work. Working with new equipment and software is an inspiration to us.
Thank you for taking the time to post.
Adam, If you set the window in the base over the bolt hole in the vise, you could have set the locking lug right down on the bolt, then once the bolt was started turn the base till the window was over the other bolt hole and start the second bolt into the second lug.
"There are no mistakes, only lessons."
-Dad
Still, a beautiful job!
Excellent! And a little human... which is excellent.
I don't know how many mistakes like that I've made learning "while doing stuff for myself." If it's functional, who cares. You both learned something and came away with a usable part. That's still a success even if you prefer perfection. You are way more confident now Adam. When you started you were just straight up intimidated by the whole process (which everyone should be at the beginning). Now you are just about to the point where you know what you need to look up. Which is a good feeling because crossing into the self-sufficient learning zone means you are really on your way.
Looking good! Thanks for keeping in the mistakes it's inspiring. I make tons of mistakes in my garage and seeing you make them too reminds me that we're all human.
as always, appreciate you showing the mistakes, explaining how and why they're mistakes, and going through how to avoid them in the future. I don't know much about the CNC things, but I appreciate you taking us on this journey with you. You're doing great!
You could make a beveled washer to fill the void. I’d enjoy that video.
Please keep sharing how you’re using Fusion 360. Thank you!
You can just rotate the base to place the access window with the hole for the screw one side at a time!
Yeah, I was laughing along with him. He was definitely experiencing a brain fart after a long day.
I was wondering myself how many people were squirming in their chair watching him struggle with putting in the lock bolts from the top, when done from the bottom by just rotating the window to the bolt hole and inserting the lock (nut) and bolt, then rotate to the other side....
I was one of those screaming at the screen to turn it over and engage the bolts uner the hole. Adam didn't hear me but the neighbours did!@@HoppersLab
Adam, you need a light up on the back side of the tool head on the CNC mill. The back of the machine/table is a huge shadow. I think that will make the milling footage look 100% better. Love your channel. Shout out to Abby. It’s cool to see her more on the channel lately.
Good video,Adam.Learning something new every day.Thank you.
I have a cnc router for woodworking, I also use fusion 360. Outside of an auto cad course I took, I pretty much taught myself how to make things in a 3D cad program and transfer that to a cnc machine. It’s good you seek guidance when trying new operations but I’ve found experimenting with the program and utilizing the simulation function really teaches you a lot. Also, using safe work pieces like foam insulation allows you to test your program while eliminating waste of a workpiece and eliminating damage to your machine. Obviously if you have the means to hire professional help, all the power to you, absolutely nothing wrong with that. But also don’t be afraid to dabble safely. There’s a lot of benefits to gain from discovering something on your own. I love your channel and this build series, keep it up!
You can teach an old dog new tricks, but it takes longer...except you. You soaked this stuff up quick, but you know how to learn and you are really interested. Thanks for the lessons.
Very nice Adam, you are truly rocking this Vise. It's going to be a beaut when its done! Thank you for sharing.
that natural gray w/ black jaws and meatballs looks good
It's little mistakes like the chamfer.... That means that you are learning and you can always say that it's there for a grease reservoir! 🤔😁👍
I use fusion 360 for my projects. I learn something from your videos nearly every time. When I do the simulations I turn the model off to get a better picture of the finish product.
Man, you are getting great at this! I can't wait to see the episode where you crash it. There are two types of CNC experts. Those that have crashed their CNC and those that lie about crashing there CNC. In this case, you have moved forward. I love watching your discoveries.
Ah, the pitfalls of digital machining. Awesome vise, turning out great. Thanks, Adam.
This has been a really interesting and informative series. Nice work and thanks for taking the time to film and post it.
I know your struggling with that CNC programming but your getting better. Every time I watch a video I see improvement. And just want say these videos have been an absolute inspiration to me. This weekend I started making my 1st real tool for my shop. It’s a spider to hold rifle actions. Taking those deep cuts with beautiful straw and blue color chips no squealing no chatter the 1st thing I thought of was you. I’ll finish it off this weekend. Keep er going man you’re doing great.👍
I love seeing this journey. Thank you for sharing.
Well done, sir, what a monster of a vice!
G'day Adam. The CNC did a great job, even though the swivel base champher was .090" to deep, all I would have done is cut the flat bolt surface down .090" giving you the required. 010" champher. Then just re machine the Swivel Lock Bolt to correct dimensions in length, & all would be perfect
Really nice job so far 👏 👍🏻 👌
I find that in life, I remember my errors far longer than my successes........Chalk it up to learning a new skill. I think you're doing a great job!
the helical bore path reminds me of dropping a quarter into one of those make-a-wish coin things at the mall
Live and learn like everybody else! Great video! Great tool!
You did ok Adam you are human.
The slot where the clamps are is called a race.
To line up the bottom to the top you could have screwed in some studs in the bottom and slipped the studs thru the holes of the vise.
Screen is fine fun watching you get through this had to learn myself the curve is steep but worth it.
Great job Adam!
What a machine!! Don't fret, Adam, only you and us will know of the goof. :-)
Good job...I say it passes 100% this far. Also, yes I would hit those swivel pads with the mill to remove the "marbles" roughness to aid in clamping, good idea.
No worries on the decimal point ! It happens to us all.
Simulation software is great, but your ability to structure machining processes is even better. good 👍👍👍👍👍
Great work Adam! No-one will know about the whoopsie except you and us! 😊
Room for extra grease for the shoulder bolt. Thanks for sharing.
Adam. Nice work of the Fusion modelling, its a bummer to see the mistake, but great trouble shooting to find it. The simple model you drew is a common approach to designing and working with key features. If you wanted to add more of the features you had previously left out without the need to draw the entire item manually. Consider using the Canvas feature. In that you take a photo of the item (make sure you use a tripod with the lens parallel to the surface you are capturing, I'd also have transfer punches upside down in the holes so you have clear visual centre points). You need to manually measure between two points (hence the centre points) to get a exact distance, then in fusion after importing the canvas you calibrate the image by setting the correct distance between those same two known points you have the manual measurement for. Once the image has been calibrated you can use the outline when sketching to quickly draw your base lines before setting dimensions to get your sketch in the ball park size and shape. A second fusion feature to get training on or read about is "Parameters", these are static dimensions you can set in a single place, and apply custom names to. For example, if you only use 3 chamfer depths 10thou, 20thouh and 30thou, then you'd create a Parameter for each option with a custom name like Cham10, Cham20 Cham30. then in your tool path setting instead of using an actual number value you instead put in the Parameter name in this example Cham10. Its a great way to have at your disposal dimensions you use all the time for specific uses (Builders do the same for things like standard door openings etc). by using Parameters for your regularly used dimensions, you'll get in the habit of going to the parameters page and checking a single list before committing a drawing. Also if you need to make a change for what ever reason, then applying the change to the Parameters section of a dimension applies that everywhere that the Parameters name is used, so on a large job you'll adjust all Chamfers (in this example) from one place. I hope that gives you some food for thought, Take care D
My suggestion for installing the base clamps
With the body upside down place the base on the body & fit the bolt
Rotate the base until the cutout in the base lines up with one of the clamp holes
Put the clamp in the in the cutout & screw the clamp bolt into the clamp
Rotate the base 180 degree & repeat
I was telling the screen the same thing. It's amazing how something so obvious to some of us is overlooked by someone else.
Beautiful vice, and good job on the machining! The end is nigh!
Nice work! When you need to edit a tool path instead or right clicking and hitting "edit" you can just double click on the tool path itself and the edit screen pops up. On chamfering operations like that I like the chamfer mill to be offset down in Z as much as possible (chamfer tip offset value). That means you are actually cutting with the larger diameter of the chamfer mill. This gets the SFM of the tool up and helps make a cleaner chamfer especially in aluminum.
enjoying your build. it's a machinist's hotrod. i dig it. 👍
Hey, I have really enjoyed watching you machine this vice. I am always trying to improve my skills and sometimes I mess up a little. The trick is to make your mistakes only noticeable to you, except you put your mistakes on UA-cam.
Really cool you taking on Fusion and sharing what you're learning. I don't know how to use it at all, all the tips you can share are fantastic!
Big beefy vise needs a big beefy chamfer! Honestly if you didn't explain the issue, it would look perfectly reasonable to me. I'm glad you did explain though, the process for double checking the simulation was interesting.
I'm setting in my drs office watching your video and you are wearing the same shirt that I have on.
Sounds like it might be a bit crowded in there. 🙂
Thanks, Adam. Really impressive to see you get you kick CNC's ass!
I modified my swivel base vise. I had problems with the swivel clamps binding unless I loosened them right off. I installed springs on the clamping bolts that pushed the T=nuts away when loosened. Worked a treat.
Looks great. More learning bud.
one hell of a Vice
Those darn decimal places. I made a batch of bronze gears once where I had the depth of an internal shoulder off by a zero after the decimal point. Fortunately for me the gears functioned fine in the application. I feel your pain. While I can't say I will never make a similar mistake again... I haven't yet made another similar mistake. As a machinist my best hope is that I will remember all the mistakes I have made and make fewer of them in the future. It's all about attention to detail. Sometimes the mistake is way back in a calculation (or data entry point in your case.) Fine video Adam and fine work. Thanks for sharing.
If the radius is reducing then it's a spiral path, not a helical path.
Oh hey, that vise was made here! Didn't know we did that.
Good job. Thank you 😊
Nice job Adam. Sorry for your slip up :).
My thought for assembling the swivel base would be to do it upside down as you started off. Place the swivel base on top, then install the swivel bolt. You can then simply swivel the base until the access opening is above one of the toggle bolt holes. Drop the slot nut into the slot through the access hole directly over the bolt hole in the main body. Install the toggle bolt loosely. Then just swivel the base 180° to line up with the second hole & rinse & repeat…
Oh, that was so fun to watch. Good job! Your chamfer width problem is a common one in all computer programming. Especially when your CNC program hasn't been used very often, it would be useful to put in some tests to see if the numbers being punched in by the operator are reasonable. For example, here, you have a subprogram to chamfer the end of a bore hole. I can't imagine you wanting to make a chamfer width of less that .002" or greater than .02" in most circumstances. You can likely come up with better bounds than I can. But, as you said, a chamfer width of 0.1" just looks weird. So, add some code in the first part of your chamfer program to test whether the chamfer width punched in by the operator is within reasonable bounds. If not, pause the program and give the operator an error code that means "unusual chamfer width". If the operator knows that his boss really wants such an odd chamfer width then the operator can tell the program to continue.
Very nice, series is great
Yay, more shaper videos to come!!!!
If that .1 chamfer bothers you too much ... make it a feature and make a new lock bolt with a corresponding cone shaped shoulder. THAT would be a challenging project on the CNC lathe!
13:16 .. The ida of heat shrinking a utte seems a bit I don't know, a bit different at least.
BUT when you think of it? There's no moving part nothing to wear out, it's super compact when finished, and had GOT to WAY cheaper than the compilated and exact machining needed to make accollet.
I was reading on lime the life span of a shrink fit holder can be thousands of heat and cool uses, if properly heated and cooled as Adam was showing as mandated by the manufacture.
Something I DIDN'T think of is tool life of the cutter is normally extended GREATLY, with Twice to EIGHT times the utting lifespan, due to lack of vibration, flex and "whipping" a tool gets when helded in a common collet. Especially with solid carbide cutting tools lie Adam is using.
I find this very interesting!! Amazing!
Great Video...Thank You...
Adam, I know you said that the(miss cut) is “no big deal “ but given that you pride yourself on your work accomplishments and it’ll be on your mind for ever, I have a suggestion. Spray weld it, and then recut it. (just a suggestive thought).
How mesmerizing was that ?
Next time you need to put the two pieces together, do it upside down, rotate the opening over the bolt hole and get one started. Then rotate it 180 degrees putting the opening over the other bolt hole and get the second one going. This way you can see what you are doing.
Thanks for sharing
This is the type of CNC content I've bene waiting for
You could make a cool, triangular cross-section filler washer for the overly chamfered bore. Something contrasting like brass would look good.
Nice job Adam...
Good learning experience!
Looking good
On the Mac a screen recording is very simple. Open QuickTime and choose File > New Screen Recording. You can choose to record the entire screen or use the “crop handles” to select the area to be recorded. Hit the record button on the bottom interface and when you’re done, click the stop icon on the top of the screen in the task bar. It might automatically save the video on the desktop as a .MOV file.
Phooey!
I was hoping you'd mount that bad boy up on a faceplate and run it on one of the big lathes. 😜
One trick for checking things: run the simulation and use the inspection tools to verify the appearance and dimensions of the final part. If Fusion doesn't support that, other simulator tools such as CutViewer will let you take cross sections and measure features.
Check your arsenal of old tools to find a spot facing tool. You've got such a collection that i bet you already own one. That will give you a nice circular machined flat centered on the hole
Just FWIW, based on how your static model showed through in the simulation, this looked about the same as I thought it would. Keep practicing!
It's Always Something©
Those holders are very cool! First ive seen of that system. We have some Haimer 3d probes and absolutely love those.
Thank goodness that mistake happened here instead of an expensive part.
The tapered bore visually looks like the shaper cut it. Very nice. And mistakes are where we learn. Even if you caught it at the beginning, you would have had a 100 thou divot and you wouldn't have been happy there either.
Hey Adam nice work. As a possible improvement you could make a quick change on the swivel bolt outer flange diameter and run a new part in the lathe which will give lots more surface contact between the swivel bolt face and swivel base. a perfect example of the beauty of CNC program saving and editing for reuse. The swivel bolt flange overlap could come into play with heavy loads when prying while using the hardtail vise. The contact patch looks to be minimal with the 100 thou chamfer. The beautiful contoured face and the now perfect concentricity between the base bore and the wall taper wall gives you lots of room to enlarge the swivel bolt diameter and get a much larger contact patch. You could also put a larger Abom 79 logo on the swivel bolt too with the larger face.
