How to Set a Flycutter to Machine a Specific Diameter

[@Ultimateflying1]

Learning something new everyday to help better my machining skills. I would have loved to do it for a living. But didn’t know the math. Now that I’m older the math is making more sense, and your videos are helping a lot with that stuff. So now I get to enjoy machining as a hobby instead!! 221

[@MaxWattage]

Another excellent video. Thanks Joe. The first rule of 221 Club is: You do not talk about 221 Club. :-)

[@duckslayer11000]

Who doesn't love these videos?

[@brianjohnson217]

Hi Joe , I've always struggled setting a flycutter accurately. After watching you video on setting a flycutter , shan't struggle anymore. Incidentally all your video lessons are great . RESPECT !!

[@ShadonHKW]

Would love to see that tool grind you used, shredded with that downfeed, was that the 221 grind?

[@kendog4570]

I used your second method years ago when setting up a boring head to make several different heads for a rifle receiver wrench. Thunk it up all by myself. Made 221 of them. One of them was for a Remington 700 in 221 Fireball.Thanks Joe

221B Baker Street was Sherlock Homes address

[@prairiemountaineer]

I love your videos that have a simple and elegant way of using common tools to find a solution to a machining problem. Thinking outside the box should be taught in school. Apparently I stay up 83 minutes later than Bob Jones as it is now 2:21 here.

[@raffiaroyan1118]

The knowledge I pick up from your videos in a few weeks would have taken a lifetime to amaze as a machinist 20 years ago... 221

[@thomasjake3920]

Feeling slightly dyslexic, so here's a hearty 122 at the best 221 channel on KZbin.

[@robo11735]

I'm new to machining, and really enjoy your content. Straight to the point, no BS, no rambling, all meat, no filler. I only have a 7x14 mini lathe at this point, but I can apply all of the concepts you show here to my humble hobby projects, and I'm very appreciative of your time & patience. I think I have a lot of videos to catch-up on, 221 at last count, but be assured I will watch every one of them. Thanks for doing what you do.

[@joshuagolden6025]

From a farmer of over 221 acres, appreciate everything you do. Learned so many things, to make my parts better, chips faster, and less scrap. 👍🏻

[@itsaposcj5]

One more example of why Joe is the best. I searched for setting up a boring head and no one had anything on measuring the cut. Searched boring on Joe's channel and the perfect explanation came up. Thanks Joe !!!

[@stxrynn]

After seeing the Texas Country Reporter piece, I get how you think. I really like the visual way you teach. It really works for me. I didn't understand how you hit me between the eyes almost everytime you have a vid. Now I do. Thanks man! You are a great professor.

[@joepie221]

Much appreciated.

[@SasquaPlatypus]

Thanks Joe!! I use your setups all the time now. Just got all the tooling to do the inverted threading tool to cut away from the chuck on the lathe and it's saved me a couple times now. Just wanted you to know your vids are appreciated, keep em coming!

[@PrettyHateMachining]

There are 221 reasons why I love this video.

[@lupuszzz]

I like all the machinist channels on KZbin, but I love your explainations and tricks. You are bridging the gap between theory and practical problem solving like no other. Excellent work, great explanations, clear messages - it can not be done better. Thank you for sharing things with us, which we did not learn and we would have never discovered without you!

[@tomboxyz5564]

I once needed to make a 20mm hole in some part at work, had no 20mm drill, the only 20mm endmill we had didn't fit in the collet (very old crappy Polish collets and the shank was over 20mm) so I grabbed some steel rod, turned half of it to 20mm to hold it and the other half smaller than the next smaller drill I had. Cut a slot in the end of it with an angle grinder and files (no way to mount a saw on the mill we have) and drilled and tapped a m3 or m4 hole perpendicular to it I cut of a short bit of and old 5mm HSS turning tool and ground a new cutting edge, put that in the slot, hold it down with a setscrew, plunge on the mill into a predrilled hole, adjusted the cutter and did all the other holes Guys at work were surprised my scrap metal tool worked

[@joepie221]

Necessity is the mother of invention.

[@ljones464]

You never fail to amaze me with your logical 221 approach!

[@davidgarrison4468]

Keep them coming!!! The more the merrier, and the easier it becomes for me to get a machining setup done with out having to spend an entire day thinking about it. Watching and listening to other folks that have already solved problems is the best way to learn! Two Hundred Twenty One.............

[@joepie221]

I agree. Why struggle if you don't have to.

[@glenj.taylor2938]

I would imagine there are at least 221 operations of yours that I have yet to see. I've watched quite a few but I'll keep watching and rewatching until I've seen them all. Then, I'll watch them all again... a few more times. Thank you Joe.

[@davidwillard7334]

YOU'RE !! A !! FOOL !! FOR !! CLICKBAIT !!!

[@Etol1963]

I don't own a lathe or mill, but I love working with metal and welding and there are 221 reasons why I like your channel. It clearly shows that You love what You do and Your teaching ability is outstanding. Keep it up Joe. A very big 'Thank You' from The Netherlands.

[@benno25132475]

221 just like to say thanks for all you do for the machining community thank you stay safe.

[@joepie221]

Glad to do it.

[@MrPallingo]

You are a straight-forward, straight-shooting kind of instructor. I enjoy learning from you 221 ways.

[@mdshunk]

Wow. Thanks. Can you talk about the grind on your flycutter tool some day? Nobody's really gone over that in any detail. Two twenty-one!

[@joshua43214]

I second this. It looked like the tool had a lot of negative lead and a lot of positive rake - not what common wisdom says gets a finish that nice in aluminum.

[@petedawkins7899]

I was born into a Machine Shop family in NC and started when I was 9, Iam 62 now and I have learned some Facts & short-cut tricks from Joe. I have so enjoyed watching and would like to meet you and just have a long Southern talk with ya Joe . Thanks for sharing your knowledge! Pete Dawkins...221

[@joepie221]

Thanks Pete.

[@henrikskott]

A big selling point is which one you want to build. The enthusiasm you had for the lathe was very infectious so the one you want to build is the one I want to watch being built! I do dream of owning a Shaper one day, but when I get to that day it will also mean I have already acquired all the other, arguably more useful, tools, like milling machine, band saw and possibly even a wood lathe too. But as This Old Tony put it: It's like watching a camp fire.

[@richcharlijohnson1112]

I am a new hobbyist and had a mini mill for one year and already have a product that I sell in small numbers. Thank you for taking the time to explain everything you really are a master in your field, only draw back is you make everything seem so easy. Keep up the good work.

[@billbarnes1043]

Work nights, up all night on the weekends, spend them learning. As an electrician by trade, 220, 221 it is all good! Keep them coming, look for them every week.

[@esosoteric362]

Thanks Joe. Useful ideas.

[@3006SharpShooter]

221 I am a gunsmith who is trying to expand my knowledge in machining beyond what my job requires. You are my go to buy for stretching my boundaries. Thank you.

[@joepie221]

Thank you. Glad to help.

[@johnothanmichaels1067]

Joe Pie. Just wanna extend some due gratitude's, been watching your channel for a few months now and I have learned not only some great tricks and techniques, but your ability to see things from whatever angle and paint a clear picture of each process supportively towards all skill levels.. well I have really gained huge in my overall perception of the sport.221 Great Job! Thanks Joe!

[@joepie221]

Glad to help. I hate to see guys struggle. If you ever have a particular issue, feel free to ask a question. I'll get back to you.

[@martyscncgarage5275]

Thanks Joe. There are over two hundred twenty one reasons why I watch your channel. As a creator myself, I know how much effort that goes into creating the videos.

[@Robonthemoor]

You should be teaching the young top grade engineers of today your knowledge, at least rite a book with it all in, yes it would be as thick as Machinery hand book & more, but well worth it, your instructions glide into practice backed up with mathematical instructions too. Your dedication to detail (gun action you produced) without clatt noting bigheaded or belittling comes from you, one serious straight forward man, Texas would be lost without you. What ever you do don’t get fed up making videos, on screen perfection. P in your name, passionate,practical,perfection. Tom L seems to have taken a well deserved back seat these days & hay that man is fantastic too, keep em coming brother fantastic channel.

[@joepie221]

Thank you for the compliment sir. Tom L and the other You Tube hosts were my inspiration for sharing my knowledge. If we all knew what the other guys knew, it would be scary how smart we would be. I will never profess to know everything, but I do consider myself a high level problem solver. Take care.

[@knlazar08]

Once again, awesome, innovative, ideas, 221. I've been avoiding setting up fly cutters off of the machine for years, because of the difficulty in getting an accurate setting just by trail and error. It would take me a long time to get it right, so I would just do it in the machine, and avoid getting the tool set up off machine before hand. I never even thought about using a V block and the dial indicator set up vertically. DUH! (slap forehead). So obvious once you know it... Thanks again. Ken

[@AlecSteele]

Thank you for fantastic tip number 221! Another great video.

[@joandar1]

Been awake for about an hr, the sun is up enough to go out to the shed now. There has to be at least 221 applications for a precisely set dia or radius for shop projects or jobs. I use a similar tech to the second one but I like the simplicity of the first as it can do different dia's without taking the tool out of the machine. Thanks for that Joe. Cheers from John, Australia.

[@joepie221]

Thanks John.

[@Denny98059]

I am a newbie to Machine working. And at my age 65+ I feel sometime it is a little to late but the way you do things is really teaching me a lot. Thanks 221 I will always watch your videos...

[@bryancrotwell4125]

Listen Joe I got some things to say!!! The videos you post are the best machining instructional videos on the internet, that I have come across!!! You are knowledgeable, you know the trade better than 99% of people out there, and more importantly, you can effectively explain concepts. You explain the math behind things, you draw it out, and give physical demonstrations, everything that in my opinion is enough for 99% of people to properly understand. As a fellow (although young) machinist, I am always enthusiastic when you post a new video, due to I walk away feeling as though I am now more skilled. You are passing on the knowledge you have gained through years of experience, selflessly, which in my opinion is one of the most honorable things someone can do for another person, let alone a bunch of strangers on the internet. All that being said, keep the videos coming, 221!!! From one of your many students Bryan.

[@crtv5]

Thanks for passing along your wisdom Joe. Speaking of passing, my dad used to own a '62 Ford Fairlane that would pass a lot of cars due to the 221 V8 under the hood.

[@gyromike1966]

Joe, your tips make even amateur self-taught wannabes like me look good. I have a specific job in mind for this one. 221 thanks!

[@kevingrumbles2306]

Wish I'd seen this a week ago. I just did the guess-and-check like chump. Thanks for the video!221

[@russelldold4827]

Always worth watching 221. I'm of a similar age to you and am getting back to the fun of machining after some 30 years away from the workshop, and I learn something new or am reminded of something I'd forgotten in every video you post. Thank you.

[@pgs8597]

Excellent demo Joe. Thanks Peter

[@timbufordbriggs]

221 Another great tip. I get up around 3:30 each morning, get my coffee, get my pad and see if there is a new video from Joe Pie. Thanks!

[@johnpilagonia5238]

That might have been 221 times more useful than I expected. Always interesting. Thanks

[@davejohnson5293]

Thanks Joe, I'm a beginner home hobby machinist with a Smithy 1324 machine. I learn something every night while watching KZbin before I go to sleep. Please keep up the good work teaching! 221 Dave

[@joepie221]

I've always enjoyed learning a new technique and adding something to it to take it to the next level. Thanks for watching.

[@cecilbroom5652]

I have a friend who is a retired shop teacher. He told me about your channel a couple of weeks ago and I'm really enjoying it. 221 Thanks for all the good stuff.

[@markpetersen912]

Thanks Joe. I used a variation of your method years ago on a job. My college instructor told me this job (one off, odd job over the summer for my old highschool chemistry teacher) couldn't be done without a CNC. That only made me more determined. With a fly cutter and a .250 carb endmill I made the whole job happen. I measured the diameter of the quill of the machine and then with an indicator got the diameter true to within .001" of the nominal, but also had to have a dead flat bottom so I used a left hand, carb inserted lathe tool to true the edges and then blended in the remainder of the bored with the endmill and stoned it smooth. Thanks for sharing this with everybody! 221

[@mattholden5]

@Joe Pie Thank you for another exquisite lesson. I've been struggling to find root cause of shallow cut, muddy finish for the last four hours and I think this vid pointed me to a preload problem (spindle bearings bouncing). I'm going to 221 sleep now, as instructed, and recheck planar finish after I tighten up the central axis.

[@therealmdavey]

Joe, you have 221% of my attention with your content!

[@klistada1]

I'm a dummy but every time I watch one of your videos I get just a little bit smarter. Thank You. If you keep making videos and I keep watching maybe one day I'll have an IQ of 221

[@StripeyType]

The amount of stuff I learn from you and other machinists while my code is compiling is really great. I picked up a used Enco 14x40 lathe - let's call it a "Model 221" - for a song a few months ago and the wife let me put the three quarter ton monstrosity in the basement. Between you and some other great instructors on KZbin, I'm able to get home and make something out of steel rather than just software. Thanks for all of that.

[@MikeSessler]

I'm not a machinist, nor do I have any really cool milling or turning tools. But I sure enjoy watching skilled people make cool stuff on channel 221 of the KZbin. Thanks, Joe!

[@gregorland1697]

I have been watching dozens of your KZbin videos on my smart TV. I am not logged in on the smart TV so you get no credit for me watching them. I am not a garage machinist but I got the urge to buy a Chinese mill machine and Chinese lathe. I use to deliver bars to machine shops in WI, IL, IN, OH, and MI. Some shops were small and some shops were very large with the latest in CNC. I marveled at all the stuff they could make out of the material I delivered. I bought a fly cutter and wanted to make a hole of radius .8125 out of two pieces of aluminum 1 inch wide and 1/2 inch thick. Each part would have a 180 degree arch and then be bolted together to fit on the yoke tube of my 1961 Piper Comanche. Attached to the aluminum is a ball mount that attaches to a Ram mount that holds my Android running navigation software. I do not have a digital read out. As I struggled with the project I finally got the hole carved away. I probably did everything wrong but I think it will work. I have not had the time to check the fit on my Comanche. I need to get a stone cutting tool to dress the stones on my craftsman grinder. The hardest part was cutting a HS steel tool on the grinder. I painted the two parts to be machined with the blue stuff and gradually worked the fly cutter to the proper circumference. Took me hours. I remember you saying not to wear a watch so I took my watch off and lost track of time. Thanks for all the info you give. I easily get overwhelmed. Regards, Fred Z, Orland Park, IL

[@joepie221]

Thanks for the feedback Fred, I am glad my material is helpful. Feel free to ask a question if you ever get jammed up.

[@niek1954]

Really like your videos. I'm a 63 year old newby at this stuff and you're really enlightening me. Niek from The Netherlands

[@MartsGarage]

2 methods shown. 2 excellent pieces of advice, 1 of which wasn't obvious to me before I saw it. Thanks Joe.

[@DavidKutzler]

I'm a long-time subscriber, but, by an odd coincidence, this popped up in my KZbin feed. Earlier today I used the first technique to set a cutter to cut a one-inch radius into a part. I'm building a boiler for a model steam engine, and I needed a part to mount flush on a two-inch diameter boiler. After cutting a one-inch radius into the mating surface of the part, it sat perfectly on the boiler like a saddle. I was quite proud of myself for thinking up this technique, but you just can't get one up on Joe Pie.

[@joepie221]

Thanks. Take pride though because you thought it up too. I did the same with a scaffold hitch knot about a year ago.

[@kentbelew5741]

I'm certainly glad to have found your channel. I've been machining for the better part of 50yrs and gunsmithing as well and I have learned many useful techniques from your videos. Thank you, KB

[@joepie221]

Thanks for watching. You may enjoy the AR series if you are into gunsmithing. Take a look.

[@gregheideman36]

As always, great stuff!. You've inspired me to re-wire my lathe motor to run on 220, 221, whatever it takes!

[@Hirudin]

Good stuff Joe! Now I'm going to watch two 21 Jump Street movies...

[@billdlv]

Will have to try with fly cutter next time, never thought of that for boring work. I use that method for setting up the boring head with the borite bar, it uses TT-221 inserts BTW nice system.

[@5tr41ghtGuy]

Single point cutting for the win again! I've never considered a fly cutter for this purpose, so I really appreciate that Joe shared this :-)

[@thetrevor861]

2:21 am and it isn't a school day and I haven't finished with the Internet yet. Interesting as always. Dead simple technique, AFTER you have shown and explained it. Thank you Joe.

[@merlinmagnus873]

I really needed that first technique a few months ago cutting some large approximately 221mm motor risers for a machine. Spent an hour slowly trying to sneak up on the right fit. Thanks as always for the invaluable advice.

[@CyclesInc]

I have to say that I think you truly teach people practical things they need to know to become better machinists. The techniques, setups and tricks to do work in a proper manner. I have used this technique to cut valve pockets and skirts on pistons of different diameters for years. I know your RPM is around 1500 but the sync on your camera makes it look like 221.

[@bernhard5741]

Thank you again for another excellent video. I am just a wekend warrior/homeshop machinist but you just gave me another 221 reasons to watch every single one of your videos. Thx, Bernhard

[@Drymarr]

Thanks for the great videos Joe. If you're ever up this way drop in, I'm at 221 Clover Lane.

[@carlquib]

Thanks Joe, tip number 221. I use a very similar method but my feel isn't as good as yours so I use another block against the face you edge found and then set an indicator to that face. I can then use the indicator to dial in my fly cutter diameter. As you said when setting the cutter on the plate, a bigger indicator tip is better and it still takes some fussing to get it right.

[@stevejones307]

I'm not usually one to comment but after watching 221 of your videos I thought I had best make an effort . Keep up the great work Joe

[@houseofbrokendobbsthings5537]

Thanks Joe. Took a few minutes to grasp how simply you completed this process. I had to rewind and walk it through. Finally it sunk in that the edge finder was centered on the part edge and you walked the flycutter out to establish the radius. Very fast and accurate. _Dan_

[@joepie221]

You got it.

[@russellhodges7906]

That's an ingenious that use for that 221 fly cutter! Thanks, Joe.

[@samrodian919]

[@stanwooddave9758]

You know Joe when I walk my dog @ 221, it's very dark out. So, now I'm going to take your advice, and go to bed. Great video, and thanks for sharing.

[@ddcd53]

Thank you for one more of the 221 really useful tips from your bag of tricks. I would probably have never thought of this one. I'm really thankful for you and Tom, Abom, Keith, Mr Pete and all the other machinist posters on here that are so gracious with your time and knowledge and sharing with us. I work in a CNC shop , but I do some fabrication and machining at home and have learned a ton of tips from all of you. Thank you. Dan

[@jamesbrown8766]

Awesome tip and very timely-Thanks! I need to make some parts with an accurate radius, and this technique seems ideal. I’m just glad I don’t need to make 221 of them!

[@samrodian919]

Joe what a brilliantly simple solution to the conundrum of how to accurately set the fly cutter diameter the first method being the most practical one. Too much maths involved for my old brain for the second lol

[@Shagula420]

Exactly the video I was looking for. Thanks so much!

[@MichaelLloyd]

Thanks for sharing a life's worth of experience with us Joe. That ROT t-shirt reminded me of when I dislocated my shoulder :D It wasn't ROT related. A friend and I were riding back from Johnny Cheese Performance during the ROT weekend. To make a long story short, bad road, sharp curve, new rear shocks, tree :) bail... The ROT had most of the hospitals and almost all of the ambulances tied up. It took forever to get transported and even longer to get looked at. Ahhh the memories :o) 221

[@robertoswalt319]

Hey Joe, your videos are the high point of my education on how to properly operate metal working machines. Take care From 221 Lubbock Texas

[@federicomoulins3027]

Thanks, Joe! Always teaching masterfully. In my case, sometimes the planes are indicated by the length of the circumference, or perimeter, and it is a little complicated to locate the center, and from there we start with a boring head. It is not easy for me, but there is a nice result. I will use your method with and we will see what happens. Again, thank you very much! 221

[@nickprescottskymap3dltd348]

Hi Joe, thanks very much for sharing your knowledge and experience. I know it takes a long time to set up, film and edit videos but if people like you were not prepared to take the time and effort to show others their knowledge people like me, who are trying to learn to machine for a hobby and have had no formal training, would rarely succeed. Thanks to your help I have more confidence to try things, and your solutions (together with the fact that you take the time and effort to show multiple ways to solve a problem) are a godsend - especially when you don’t have all the latest gear and can’t afford to break things trying stuff out. I’m sure I’m not alone when I say how much I appreciate the videos that you put up, and the fact that you invest your time in helping other people without expecting recompense. We could do with a few more like you out there - at least 221 more would be good! Please keep it up, and continue to share what you do with us. Thanks very much, Nick (Nottinghamshire, UK)

[@planeflyer21]

Great stuff! One of my instructors was infatuated with fly cutters but he never showed us this trick. This is a great boon to the person with a small shop and a limited budget. You are doing a great service to the machinist community here, Joe! "A good name is rather to be chosen than great riches, and loving favour rather than silver and gold." Proverbs 22:1
