Precision Toolmaking Making an Edgefinder Part 4

[@stephenreeves9025]

I like the project-based video series, there are several things Stefan has made that teach excellent machine shop practices and you get a useful tool to boot. Thank you for your time teaching us.

[@StefanGotteswinter]

Tom, great build, I prefer that over opening boxes a lot!

[@pietzeekoe]

This kind of stuff must be right up your alley.

[@renee46]

Appreciate all of your videos keep up the good work

[@LarryDoolittle]

Now I know how an edge finder works. I could not found any info anywhere until you came to the rescue again. Thank you.

[@KnolltopFarms]

I wish I had a bank of computers to send your subscriptions through the roof because I don't just like watching your projects...I LOVE IT!!! Thank you so much for everything you do for this community Tom, you are my Idol! Aloha...Chuck.

[@raincoast2396]

Always interesting to watch a master tool maker, making close tolerance measuring tools, so he can make better tools!

[@TrevorDennis100]

With the greatest respect to Stefan, Adam, Lyle TOT etc. this is fast becoming my favourite engineering channel. The content is excellent, and the relaxed delivery makes it a pleasure to watch. Being so upfront about the inevitable 'bozo' moments is also very reassuring. I'm retired now after working 38 years as a toolmaker, design engineer, and finished running the external instrument calibration and repair at Ford UK Product Development in Essex. But thankfully, I now belong to the local Menz Shed which while it does not have an outstanding engineering section, it is not bad, and I am constantly working to improve it. Isn't it strange that after doing this stuff for a living for so long, we still want to keep on doing it unpaid after we retire? I have an edge finder that I made > 40 years ago, that uses ball barrings, but I recently bought a similar edge finder to what you produced in this series of videos. It came from Amazon, but I am fairly sure it is of Chinese origin, and it does not really work. It does not slide along the work piece when it gets to the offset radius. It keeps on spinning and becoming more eccentric. I took it to bits today and lapped the faces on a 1200 grit diamond stone, and lubed with WD40, but I can't test it till I get to the shop. I am hoping that's all that was wrong with it, but your spring looked lighter than mine, so I might try stretching the spring on mine if it still does not want to play nicely.

[@BuildSomthingCool]

This was a great video series. Thanks for taking the time to make it.

[@SuperSecretSquirell]

From the get-go, I didn't really understand the "how" of how one worked. Now that I see the finished product and it's use, makes sense to me. Beautiful work as always.

[@markr6017]

Totally awesome Tom. Definitely titled this series correctly, "Precision", gotta love it And .... Abomb is chuckling cause you make cute little things

[@williamhardin5254]

Great little project. Really enjoy these little projects as much as the large ones and you ended up with a useful tool. Thanks for sharing.

[@MattsMotorz]

Wow great work Tom. You're one hell of a Machinist!

[@iancraig1951]

Making tools etc will always get a thumbs up from me Tom---they are always interesting and enjoyable..

[@marlorup]

A great set of videos Tom. I certainly enjoy this type of video. Not too long, but still worth watching every minute. Thanks for sharing,

[@mortezarahimi6784]

Thank you Mr Lipton for sharing your knowledge, as you mentioned at the end of the series i just came here to say i really liked this series. actually i want to see tools and its uses in a real projects.

[@Ujeb08]

great work on the edge finder Tom! It should come in very handy on those larger diameters. The videography was fantastic too! Yes, keep em coming.

[@DenHvideHund]

Well done Tom. Always very satisfying to see you work. Really like your attention to detail.

[@Marthis218]

I very much enjoyed watching the series Tom. Thanks!

[@billlee5307]

It is so very interesting to watch you work. Being mostly self trained I find that techniques I had to puzzle out myself track how you do them about 40% of the time. I sure wish I had been able to watch these videos to learn the other 60%!

[@AddictedtoProjects]

This thing is GREAT! Awesome job Tom. But then again, I wouldn't expect anything less from you! :)

[@BrickTactical]

Love the video Tom! Please do a video on those little toe clamps you use on your mini pallet. That would be an awesome project!

[@MarindeVree]

Awesome to see the time and craftsmanship that goes into something you take for granted. Thanks Tom!

[@alexanderhowa9707]

Thanks Tom. I really enjoy anything u build. Waiting for more of the baby Wilton. Mine is just a car behind yours. Really appreciate all the cool shit u do.

[@paulbuckberry7683]

Really enjoyed that series Tom. You're a true craftsman.

[@oxtoolco]

Hi Paul, Thanks for the nice comment. Cheers, Tom

[@Keith_Ward]

Great series Tom and without too many parts. Good to mix it up with both complicated and simple series.

[@AmateurRedneckWorkshop]

Great project and the tool turned out perfect. Thanks for the video.

[@billmoran3812]

Really good project, Tom. Love seeing new things like the cylindrical grinding and lapping of small parts. The precision parts are very interesting.

[@oxtoolco]

Hi Bill, It was a fun little project. Thanks for the comment. Cheers, Tom

[@BigBarn101]

Excellent work Tom! I enjoy your videos and appreciate you sharing your knowledge.

[@billrees4638]

Thanks Tom, I have always wondered how edgefinders worked. As always enjoy your video content. Bill

[@denzillong9878]

I really enjoy these series.As a hobby machinist I learn a LOT from watching your build series. I find it particularly useful seeing how you setup the work and explain the why and how of it all.Extremely beneficial!

[@steelguitarfan]

I very much enjoyed watching the series Tom

[@bradapprentice1397]

Slicker-n-slobber Tom; as usual. Purdy little narwhal ya got thar, and it works good too! Hmmm… OXTOOL!… precision, performance, permanence, perfection, every time! Brad

[@shawnlund]

This was my favourite series of videos so far Tom. Lapping the outside diameter of the edge finder was one for the brain bank for sure. Thanks for taking the time and effort to share your knowledge.

[@KenToonz]

Loved the build and learned a lot. Thanks Tom!

[@oxtoolco]

+KenToonz Hey Ken, Thanks for the comment. Cheers, Tom

[@FinboySlick]

Toolmaking is definitely among my favorite kinds of machining videos. Especially precision pieces like this!

[@martybernier9313]

Better than watching How its Made on the Science Channel. Outstanding series.

[@CafeenMan]

Your personal knowledge base amazes me. Really.

[@josephmagedanz4070]

Fun and useful project, Tom. Thanks for sharing.

[@k5at]

I really like this kind of content. Much better than watching viewer appreciation gifts. Thanks for sharing, Tom!

[@brianlrayburn2576]

Tom, super nice. Enjoyed watching the surface grinder in action. Never been around a surface grinder so, as always, good education for me. Thanks for your dedication to making new videos for us to enjoy and learn from. They're always inspiring.

[@vistastang]

Congratulations on the making of what appears to be a very fine and accurate tool. Love watching your videos Tom.

[@jcs6347]

Thanks Tom, I enjoy small projects like this and appreciate how you demonstrated the application at the end.

[@63256325N]

A job well done, and nice tool build that will last a good long time. Thanks for all the great videos Tom.

[@malcolmtill]

Lovely job. I am impressed by how repeatable it is ! Thanks for taking the time to show your work, it is Very much appreciated.

[@KimbrellBrad]

Yes Tom! Excellent content. Love the toolmakers type projects. I spend as much time making jigs, fixtures and tools as I do actual projects. Makes for more fun in the shop! Keep it up!

[@meichler23]

What a great video series! So many different operations. Done and narrated well! You have definitely earned a subscription!

[@oxtoolco]

+Mitch Eichler Hey Mitch, Thanks for the comment and sub. Glad you liked the videos. Cheers, Tom

[@claymantoo]

Very Cool!! Please do more of this fine tool making. I've always wondered what was inside an edge finder. I figured it was a spring, but couldn't visualize how it was attached. I like seeing the lapping process. And it was amazing to see the DRO as you repeatedly got it to hit zero. Very satisfying:)

[@oxtoolco]

Hi Clay, We sure will do some more like this one. Thanks for the comment. Cheers, Tom

[@pauljones3866]

Tom, great series on making a precision tool and I especially liked the part on lapping. Thanks, Paul

[@TreeTop1947]

Tom, I really enjoyed watching this edge finder series! BTW, I'm a retired tool and die maker/machinist and I really miss it. Back in the early 70s, I apprenticed under an old German tool & die maker. One of the many things he taught me was to always run your edge finder between 1200-1300 rpm, so it was nice to see you running yours @ 1200 rpm. Tree Top

[@noeltillery8950]

Thanks Tom. I love this this type of series.Your channel is a invaluable resource to the youtube community.Between your channel and books have both helped me dozens of times in the last few months.There is somthing about learning a new skill for first time that immensely rewarding.Thanks for the guiding hand.

[@fredsmachinewerks4811]

That is really nice Tom . Good reach on it. Thanks for sharing. Cheers

[@BrianFyhnPetersen]

Great work Tom, the repeatability is just spot on!

[@oxtoolco]

+Brian Petersen Hi Brian, Thanks for the comment. Cheers, Tom

[@kevindonald1780]

Nice job Tom, you didn't have too much trouble with the spring. I like the way you attached it. On the edge finder i had you had to screw the end into the spring. With two ends to do it wasn't much fun.

[@tomharp5211]

keep making this type of projects as many folks learn from them.

[@woodandstuff]

wow I'm very impressed. Didn't know it was even possible to make something like that...

[@horneygeorgeforge7079]

yes tom, I like learning how to make my own shop tools, for me I had no idea how the edge finders worked internally. thank you for sharing

[@PhilGoldblum]

Awesome product Tom. Well Done.

[@chucktipton9596]

Great stuff Tom. Thanks for all you do.

[@lesliebird5621]

Nice little interesting project Tom keep em coming

[@ActuallySettle]

What I find most interesting about precision machining is metrology, and specifically how you can create precise measuring equipment without having references beforehand. I'm sure you're familiar with the technique used to create a reference surface by grinding together 3 plates together in a specific order. In the same spirit, it would be cool to see videos where you build a collection of tooling from nothing you haven't made yourself - so you end up making an edge finder without using an edge finder.

[@oxtoolco]

Hi Nicholas, I agree. Primary standards are pretty cool. Or any other self proving devices like levels and squares. Thanks for the comment. Cheers, Tom

[@thomasvmanning]

This is the second or third time I've watched this series. Great stuff. Looking forward to another precision project!

[@robgerrits4097]

[@krazziee2000]

very nice work and a very useful new tool for the shop. thanks for the video and lessons .

[@jessefoulk]

awe. That small vise is so cute. Like a kitten.

[@bcbloc02]

Looks like it turned out very well. I would like to ask to do a test with a gage block on each end to see how close to true edge it is. I have a set of B&S edgefinders that say when you get everything running together you are at the edge, but I also see people do the kick method. I think using a gage block and the DRO to see if there is any difference in locating would be really cool. If I had any gage blocks I would do it myself just to learn.

[@chrisstephens6673]

+bcbloc02 And some say bring into touch till it kicks and then back it off till it centralises again. Take you pick as to which is correct. We are talking about milling, so tenths don't really matter much, if they do you just have to keep measuring.

[@jeffren70]

+bcbloc02 I was wondering about accuracy too. I know when I use one on our cnc, its about .0002 off on the true edge.

[@chrisstephens6673]

Surely what is important is repeatability, as any consistent errors can be added to offset due to tip diameter.

[@tomclark6271]

@@chrisstephens6673 ...What's the point of repeating the errors just to compensate later? And stop calling me Shirley!

Great series Tom, thanks for posting it.

[@jimmilne19]

Hey Tom, I really like this type of content because I learn more about making things in the shop and being able to take on jobs that come in because I have seen certain operations done on YT. Of course I pick up something from watching new tools come in your shop, but it is frustrating for me to see all the stuff I can't get my hands on, nor have in the shop. This was a great series, but know that everything you put out is of interest to me and enjoyed. Best regards. Very nice work btw. I wish I was better so my compliments meant more, but I offer my best anyway.

[@wupme]

Nice craftsmanship. And that spring sound made me almost jump out of my chair lol

Tom, That little vice is a real beauty, perfect for that project, wouldn't mind one like that myself, and the edge finder turned out real well, regards John MD

[@AtelierDBurgoyne]

I agree. I made a couple vices myself and wonder how Tom's vice parts go together like is there a thrust bearing inside the movable jaw to take pressure from the screw? Daniel

[@kzinty]

That little vice is a Suburban Master Grind. awesome tool and extremely acurate. Personally I think it is the best but new is worth well over a grand. www.subtool.com/st/mg5cvs1_master-grind_spin_index_fixture.html

[@AtelierDBurgoyne]

+kzinty I looked up the link you provided and the spin master vice does not look like the vice Tom is using. Are you referring to a vice that is no longer available?

[@oxtoolco]

+kzinty The small vise in the Kurt is made by a company called George Fakes. Its a nice little insert vise. I used that one because it has a little vee groove in the jaw for round stuff. Thanks for the comment. Cheers, Tom
