That was an advanced course in machining. Beyond my abilities but I certainly learned something. Makes my “Joe Pie - taught me something” sticker on my mini lathe valid. Thank you!

[@phase1acoustics]

You bring back many memories of my Uncle Joe Marklewicz. He made the molds for many iconic Pyrex bowls. After WWII he began working as a gage maker and retired some 45 years later. I enjoyed his sharing about laying out an ellipse. He used the company library to find equations and set up the work. I vicariously relive the memory of listening to your math lessons! Thanks for sharing your knowledge!

[@JeffSearust]

You really need to write a book on fixturing and metrology...

[@pingwax.]

This is classic Joe Pie video. Too many excellent machining tips to list. Avoiding damage to a cutter by setting the cutter height and then testing the height by rolling a pin under versus setting the height against the pin, for example. Work holding guidance that makes it look easy. Explaining the math behind the work. Really fun video. It's easy to lose perspective of how tiny these parts are; the camera makes them seem much larger. It isn't until you're holding and assembling the finished work that it becomes apparent how delicate the machining operations were.

[@ToBeeOrNotToBeHoney]

Joe, watching your videos makes me think about all the kids who don't learn math because they say, "When am I ever going to use it in the real world". Your videos show exactly how you combine skill and knowledge to produce machined objects with precision. The math is not hard, but knowing where to apply it is critical. Your example in this where the table adjustment needed to be .0199 is a great example of knowing how to use it. Keep up these videos, I find them useful and entertaining!

[@AmateurRedneckWorkshop]

Thanks for the video keep on keeping on.

[@life.is.to.short1414]

Thank you for going into detail on that dovetail. Newbie will thanks you

[@TheEvertw]

"Help me, Joebi-One, you're my only hope" Love it.

[@stephenbaker7786]

Nice work as always. I must say that your photography is exceptional. One of the things that really bothers me about many videos. Thanks

[@MatthewRulla]

Bonus section of the video is well worth sticking around for. Thanks Joe!

[@raydebs]

Great video Joe! I have been watching your videos for years now and was just remembering that as a young engineer a long time ago I had a couple of chances to see tool and die makers work and wished I could learn. You have made it possible to learn in my own time. You have provided such an amazing gift in your videos and I sincerely appreciate all the time and careful explanations. Thank you very much!

[@devmeistersuperprecision4155]

Waking to find JoeBe-Won doing this. Loving it with my senior coffee. I have a kindt Collins spindle sander. My is basic. But an options list required a dovetailed slot to work. A few have this slot. It’s filled in generally with an oak insert. I actually have the blueprints for those options. Don’t Ask How! The table casting is the same on both machines. Just one has this dovetail feature on the left side. The drawing was done in the 1940s/1950s. In it ate precisely the pin setups for measuring the dovetails. But these are inside dovetails instead of outside dovetails. Same concepts apply. It blows me away how useful simple descriptive geometry is. It would be really cool to have a summer course for kids/makers covering this. We are getting older and the kids are not learning this.

[@jamespittsfordiii7632]

I can’t wait to see you scrape in the ways. The Bi-ax scraper is going to be hard to hold

[@Ideasite]

Thanks again, Joe! It's so enjoyable to watch your detailed work and it's so easy to understand what you are doing and thinking. I have learned a vast amount & really appreciate it. I find myself shouting the answers at the screen as you go.

[@quinntalley1681]

I've been waiting for a good unloosen!

[@icbtech01]

Huge thanks for sharing all your knowledge, Joe! Great video.

[@jobkneppers]

Joe, much appreciated as always. If you want to learn machining your channel is the best. Bottom up to sky high; all included. What I especially like is your enthusiasm and joy you have doing this for many, many years by now. I think therefore you're an example for making the right choices (professionally, I don't know about your wife ;-)) in life. I hope you inspire others to do the same. Thank you Joe! All the best! Job

[@rallymax2]

Stick around to the end folks. Seriously useful Shop Gem about sizing dovetails to save to your playlist for the day you need it. There will be a quiz 😂

[@Dave.Wilson]

What you want Joe for those really tiny parts is a really mini mill to machine them in, you aught to make one :)

[@joepie221]

Hmmmmm...Good idea. Maybe a KZbin video series on it too.

[@StuartsShed]

I really appreciate these detailed explanations of accurate working methods. I like to use all these techniques to make accurate parts “by the numbers” rather than by painting everything blue. Cheers and best wishes!

[@ashesman1]

Makes my day when I open youtube and there is a new Joe Pie video at the top.of my list...

[@SierraScout2]

You are an outstanding teacher! Thank you Joe for making these videos.

[@peteengard9966]

Thank you Joe. Been waiting for an unloosen and you also tossed in a millimeter and a half. Very well done.

[@jackpledger8118]

Another great video Joe. Wish I had a math teacher in high school, or college, that taught machinist math. Would have been so much more useful.

[@mikepelelo5657]

And people say they'll never use trig. Well, they won't and when they need something done they'll pester someone who does. Thanks Joe for another excellent tutorial.

[@joepie221]

I'm still waiting for the day someone asks me what class, order and phylum a fruit fly falls into. :)

[@roberthiggins1142]

That is some great work done on those small parts, & i do like those shop gems they are priceless. Keep up the great work it is such a pleasure to watch you work.

[@IyamNadanumber]

Thanks for the math and geometry! I always learn something new watching your videos.

[@wolfparty4234]

Joe, when your good, your good without even saying anything…!!$

[@Preso58]

Looking great, Joe. It's strange seeing the mill table with just one tee slot. I guess it's convenient to have more, but it's probably not essential.

[@joepie221]

Hi Preso. It does, but its too narrow for 2. I'll make some small strap clamps and T nuts to distract from that.

[@angelramos-2005]

Very interesting,Joe.Thank you.

[@troglokev]

You had me going when that cutter got close to the movable jaw.

[@joepie221]

I've never hit the jaw doing this, but it would be an easy mistake to make.

[@michaelandersen7535]

I always learn a ton when watching your videos. Thanks for always taking the time to teach!

[@BarryLitherland]

genius!

[@bh.boilers]

Thankyou, a very clear explanation of the maths behind the pins, Ray.

[@devmeistersuperprecision4155]

That mill is really sizing up. The table looks really good.

[@TrPrecisionMachining]

very good job Mr Joe Pie,,thanks for your time

[@geneard639]

I'll say it, I think a high school out there needs you to teach 'Machinists Math' during Summer School. Young Boys, and some Young Girls, would show up and be future Machinists. But you're doing a good enough job here.

[@devmeistersuperprecision4155]

The problem with high schools is that they are like atomic bomb factories….. They all got rid of their traditional machine and wood/pattern shops. I know this cuz many of my machines came from these locations. Best one was my monarch 10EE. It’s got tube based speed control and came out of Las Almos. I tell folks that the blue glow in the tubes is residual radiation. I have had some humorous exchanges here with some believing this.

[@MrClickbang357]

You know, it's like every video of yours is fun AND a learning experience! Too bad you couldn't bottle that up (maybe load tanker trucks up?) and deliver that to our schools! Another great video, Joe!!!

[@maitajack]

Interesting set up. As a hobby machnist, I take notes from your teaching. Many thanks.

[@wrstew1272]

Joe-Be-Wan……classic nickname! Fitting for what you are doing Mr.Pie and only if you check out the second ending of the movie. Tricky move 😂

[@DustyFixes]

This is one of the videos where I wish I could hit the thumbs up button twice.

[@TomokosEnterprize]

I sure am glad I saved my Grade 10 math work from when I went back to school. Thanks Joe !

[@garychaplin9861]

Love your work Joe, beautifully clear and simple explanation. I wish that when I was struggling to understand basic geometry as a child there was someone who could have explained that there was a real use for the concepts they were trying to beat through my skull. Would have made such a difference.

[@joepie221]

Thanks, I agree. if you don't see the need or use for a lesson, it rarely sinks in.

[@Stefan_Boerjesson]

Lots of magic. The trigonometry lesson looks like the course in physics 50 years ago, and never used since then.... Some sine maybe.... The clamping examples.... outstanding.

[@russellmcclenning9607]

Thank you Joe another great video

[@allanrichards3752]

I am loving this build. I also learnt something today where we are separated by a common language. A gauge block is known as a slip gauge here in the UK. I am not sure why but it could be that the will ring together and stick or slip together.

[@davidtravis8789]

Thanks for an interesting series of videos. I have a couple of suggestions for possible future videos. If you ever decide to make another miniature cannon you might consider a screw cannon or mountain cannon of the sort Kipling mentions in his short story "Servants of the Queen". On a different note several people have posted videos on how to make a nested cube, but for you that would be too easy - unworthy of your genius. Could you make a nested dodecahedron? The math would be much more interesting - just think of all those lovely compound angles! Just suggestions. Dave

[@ChrisB257]

Great work Joe - love your work-holding methods here and some useful tips as you go along... particularly that refresher at the end using pins re dovetail calcs :)

[@joepie221]

Glad it was helpful!

[@ghl3488]

Amazing as always Joe. Thanks for the video. Regards from Wales

[@user-vs7tn5ej9w]

Thanks for the nuts and bolts at the end. You are the best. One question though, will you be scraping al the ways?

[@johneslaughter]

Great video, thanks for putting it together.

[@jaybailey3518]

Very nice !

[@glencrandall7051]

A nice piece of work.🙂🙂

[@edwardaloftis6705]

I'm working on a power feed for my mico mill. That's cool stuff you due.

[@joepie221]

Thanks. I enjoy it.

[@karroome]

There will be a quizz😂😂😂😂😂😂👍🏻👍🏻👍🏻👍🏻

[@jacknelson8397]

can't learn enough machinist tips and tricks

[@rodneykiemele4721]

Loved the math, thank you very much.

Good morning!

[@outsidescrewball]

SO MANY SHOP GEMS!!!! Thank you for your mentoring ❤

[@patrickmazzone9066]

Good wishes to you and your family great job

[@joepie221]

Thanks. Same to you.

[@metalbones]

Great, I also remove the handle or put a towel over it to not loosen the wrong vise

[@paulpipitone8357]

Joe I have two very important questions 1. Are you going to build a mini doll house work shop and lay out all your mini machines lol 2. Will you name your new mini shop Joes Wally World machine shop lol

[@MikelNaUsaCom]

perfect... thanks!

[@MPenzlin]

Another video, with some clever tricks for my "toolbox". thx

[@vandalsgarage]

Proper job! I always learn something, thank you.

[@BusstterNutt]

Thanks M8

[@mce1919A4]

Thank you.

[@raymondhorvatin1050]

It gets more amazing as it goes way above my pay grade

[@joepie221]

Thank you. I love watching it evolve as well.

[@nelsoncollar1814]

It would be nice to see all parts in chronologically assembled.

[@joepie221]

The final video in this series will be a complete build.

[@jdsstegman]

Who else loves math!! Something so simple is alot more than it appears.

[@devmeistersuperprecision4155]

Math rocks!!! My grandfather taught college math to engineers. But his thing was theoretical descriptive geometry. I still have his drawing instruments. What blew me away was that the books he wrote have been scanned into PDF form and he is now listed in Wikipedia as a mathematician. He looked like Mr Crispin with a goatie and a zoot suit.

[@RROOBBWWAANN]

The measuring rollers should be of such a diameter as to subtract an integer. For example, a shaft diameter of 2.928 mm, then we subtract 16 mm and we get X.

[@joepie221]

Please explain this in greater detail.

[@RROOBBWWAANN]

@@joepie221 YT deleting comments? I wrote a reply and it is not visible. There were no links in it.

[@joepie221]

Try again.

[@RROOBBWWAANN]

@@joepie221 It keeps getting deleted. I will divide it into two parts, I wonder what bothers him?

[@RROOBBWWAANN]

@@joepie221 I PART :) For example, if X in your drawing is 10 mm, then if you insert measuring rollers on both sides (each with a diameter of 2.928), the caliper will show 26 mm. If X is 20 mm, the caliper will read 36 mm. Always by a total value of 16.

[@williamsquires3070]

Hi Joe. Instead of trying to use trig to calculate the amount you take off the angled surface, why not just take the .023” off the opposite, flat surface?

[@joepie221]

There is a little matter of the holes in the plate already being on location from that surface.

[@motorcoach123]

The 3ed hole an oil hole or lock down ?

[@joepie221]

A vertical stop pin will be installed at assembly.

[@dennyskerb4992]

👍👍

[@yohannwilkerson6058]

If you are UN-loosening, aren't you tightening?

[@Bobs-Wrigles5555]

See what the Oxford English Dictionary says...😁

[@Radiotexas]

Words just fail me pal.

[@ramonching7772]

But isn't it once you put in a gib, the requirement for precision is thrown out the window? All that is required is to ensure the ways are perpendicular and or parallel to the some other axis.

[@joepie221]

I suppose a different type of precision is then required, but you are correct. Parallel and mating angles are the only requirement at that point.

[@johnfriend240]

I'm thinking the table would have looked better (no porosity) if you just started with an aluminum bar instead of the casting. Not many more steps would have been required, in fact, maybe less as you'd start with more bankable surfaces.

[@wrstew1272]

When you get tired of showing the world your skills…..possibly a side job as a college math teacher? Engineering students would definitely benefit from your real life experiences! I concur with the two thumbs up post 😊

[@colt4667]

If the knee bone is connected to the hip bone you're in a helluva mess!

I am bad husband. No till the garden. Watch Joe instead. Wife=mad

[@wrstew1272]

I know 😂😂😂

[@aquilaaudax6033]

✋🏼🇦🇺👍🏼

[@PaulSteMarie]

Yep, theoretical sharp edges are just that: theoretical. The techniques you've been showing with a pin are really important. Banking a sharp edge against the bottom of the vise will not give you a reliable location. Chamfers are also an issue unless you know they were precision ground and you've verified that on a surface plate.

[@devmeistersuperprecision4155]

Precision dovetails in machines has always been a challenge. Time to think thru it. Scraping them is a bit easier when the machine work is done as long as you have a good reference.

[@10-4CodyWade]

The geometry lesson was great. For those who struggle with the math, just draw everything in a CAD program and use it to calculate the measurement for you. Not quite as satisfying as a hand calculation but it gets the job done.
