I was an apprentice Tool Maker. I could watch this all day

this is the kind of work i love, i miss being on a surface grinder and sweating half tenths

I was really glad to see your trick with the reverse rotation on the end mill. Makes me feel better 'cause I did the same thing last week! I actually stopped when it wasn't cutting and checked to see if the cutter was dull. Changed to another sharper one and ...... Sping! Still haven't found the rest of the cutter.

Tom it is amazing to me how the old ways are often times still some of the easiest and surest ways do do something. Thanks for showing us how it can be done old school.

I have to go out to the shop and fabricate one of those nifty Ox FTD's (Fastener Truncation Device) as pliers don't work for Scat and bare handing it leads to road rash on the knuckles as often as not if it don't get so hot first that it burns your fingers. Yeah Tom, the simple homemade tools can make your shop life so much easier, so simple that it is one of those "Why did I not think of that years ago?"

Been using one for more than 40 years. Great accuracy. Mine was made by Diamond Tool in Oakland. Guaranteed for .0002 accuracy.

Neat! I like your little screw shortening vise. All the best! Mike

My shin usually finds the chair edge pretty quick, especially if it's dark.

Great video. No music or time lapse. Thanks

Looks like a useful way to get quick centre finding in a production setting.

Very cool edge finder. They are both new to me. I especially like the vise like tool for grinding down the cap head screws. I am gonna steal that one and make a couple for myself. Thanks for sharing Tom!

Great video Tom. Simple projects (well they appear simple, I'll find out soon if they really are) give me hope (after browsing the MSD catalog) that you don't need to be rich, or by Chinese tools, to build up your tool collection. Thanks for making your videos. I live in the Bay Area and it's gotten so expensive to live here that less and less machine shops are opening and or staying here. Even those that are still here are having to hustle so fast to make a living that they barely have room for a single apprentice. Being 50 years old and only a hobby machinist, with hardly three machining books at my local library, it's only through the Internet and generous content produce like yourself that I even know how to sharpen a drill bit, much less build anything. Thanks.

I think the chips on the first rougher you were using were much better, maybe not as good a finish but you had it dialed in perfectly, great straw colour and nice formation. Nice project. Thanks for the video.

Thanks! I had a Moore-type edge finder among my precision tools and didn't know what it was.

Great video Tom! I have a bunch of the Moore style I made way back but I never saw the Pratt and Whitney style before. ATB, Robin

Hey that holder for grinding bolts is genius, boy have i misset such a thinghy at work!!!! Please make a video on a build!!!!! Ty for the video, allways a pleasure to watch!

1. Thanks for sharing. 2. Thanks for the bozo and your edited version of it. 3. Thanks for still being a super hero machinist/engineer/teacher!

I like the idea of making one with carbide knife edges with a tiny radius for doing very tight tiny areas

I have never broken an end mill yet....cant wait til I get a mill 😊 You sure do nice work Tom 👍🏼

Very cool project!!!

Excellent as always Tom. Thank you sir.

It would be nice to hear the advantages, disadvantages, and preferred applications for both of those types, and compare and contrast them with the typical edge finders we use that spin -- of course, that is one big difference already...

Hi Tom, what a great way to start a Saturday! Loved the Bozo moment, I have those, but I try to learn from my, & others mistakes. You have a knack for making your own tools, I like that. I do the same thing, just not as refined as yours...... yet! Working on it!!!

WHAT TAPPING VOODOO WAS THAT! Watching your other video now.... You don't know what you don't know for sure.

Thanks for sharing Tom! I understand that these are more precise than the cylindrical type. I hope you compare their precision and repeatability when these are finished.

It sure is good to know that even the best of us forget which way the spindle is running

If tom breaks end mills what hope is there for the rest of us

This project looks like a good one for Abom's "new" shaper. Adam's would, of course, end up weighing ten pounds and require a massive furnace for heat-treating.

Yes, folks, even superheroes stumble occasionally. Considering all the good he does, it's OK!! Thanks Tom.

Tom: I don't care what the other comments say, you did not break the endmill...you made a short endmill with great skill!

Nice job Tom. I have a can full of mills and taps like shorty 😃

looks like the teeth of your band saw are the most effective tools in removing metal in your shop! 😛great video very interesting to watch, thank you

Love that band saw, thanks for the video.

Thanks for the video Tom, I have a set of those and I never knew what they were so now I can try it

Gee Mr. Wizard... love to see you work and grunt when Mr. Bozo visits your shop... thanks for sharing and like Fred Miller said... nice screw shortening jig... consider it stolen. ;) Interesting video... nice to see the workflow stock -> rough -> etc. very educational and I'm amazed how many little gadgets/tools you collected/made over the years... awesome. Please stay healthy and take care! ;)

Oh yes the old reverse spindle yep done that alot. Deal with tool steels alot so I'm always in low so when I need to go to high I forget to flip the switch the other way.

Love stuff like this. Many thanks, Tom.

Don't know how Mr. Bozo has time to visit you, he's working overtime on my projects.

I would like to see your method of centering the test edge between the gauge surfaces.

Nice project. Thanks.

Video of every day life for me.

Never break an endmill again by wrong direction: ducttape on the drill (above cutting surface) stick 'em around the drill, sticky sides together on the other end, leave a tab of about 1 cm, dykem blue on one side of the tab. Depending on which direction the mill goes, it will show a different color. Bonuspoints if it blows chips away from the work. Be advised, this trick might not work well at speeds where the weight + velocity of the tapetab exceeds the air-resistance (ea; if its spinning so hard that the tab is straight out from center of mill)

That mill power tapping though... wow. Impressive, unless I missed something that would make that easier.

That dye now comes it an aerosol can. Its great.

I sure love what you do Tom Keep it up

First YT video I have watched where I have NO idea what is doing on. But nice machining.

Amazing work.

Nice video -- will have to make one

Man I wish I could freehand draw like that. I used to be able actually, I'm just lacking practice since I finished school.

Oh it is a joy to look at how you clamp things down so easy!! when I do it :( maybe that is why I never make a video :) Machines do a lot of difference too and how one set them up. If i cut something it looks like a blind man has made a hair cut :)

Heh, i had a Moore type edge finder and i never even knew what it was. Always figured it was some kind of unfinished project from grandpa. :))

If I remember correctly Moore are no longer making these chair type edge finders. But when they were I seem to recall just before they quit making them they were $5k each.

Thanks for the video, I really needed my fix..

That's why you need a nice shaper machine.

enjoyed Tom!!

The one I have is used in X and Y. Has a hole on center to two edges that form on inside corner. plus its magnetic. And no, I didn't make it. SPI I think. Did almost allof my other tooling though.

Why wasnt the edge in the same place with the 2 edge finders ? I didnt see you move the vice fixed jaw and yet you got a different reading when you swapped

Oxtoolco It seems like the Pratt& Whitney type seems to be a nice little "government job", if you have access to a Wire EDM. 😆 Especially as you can heat treat it before you cut it, minimizing warpege issues. I look forward to the grinding and lapping video, especially if you show how your going to measure it. BTW, whats that green goo you use for tapping - something homebrew or is it a commercial product?

Did you ever grind these? What is the calibration process to make sure they are ground perfectly? I'd imagine the only reason to use this over an edge finder is if you need better than .001" locating. Thus, the grinding must be in the .0001" range per half.

Tom, Nice work, my favorite part is your bolt shortening jig, do you have any details on it, I want to make my own :)

Wait wait... one edge finder was used and the edge was found then the other was used and should have shown you were on the edge but didn't! Is that because they haven't been ground yet?

I have always wondered how they fid that before the modern type came around

another great video..... many thanks :)

Hi Tom, loved the vid. Who do you like to listen to for classical tunes in the shop?

new OxCAD1.0 get it at your local office supply ;)

I dont know how or where you would use these. They look neat.

Another good vid, thanks Tom. Honest question: The two tools in the beginning are off from each other? After finding the edge of the vise with the first, you had to bump the table 3ish thou to have the second tool indicate the fixed edge of the vise is centered under mill spindle again? Regardless, nice little tool to make!

Tom, I don't think the end mill was running backwards. It sucked the paper in just like it was supposed to. If it was running backwards, it would have pushed the paper towards your hand.

I would like to see their use in different applications I get the idea clamped in a vise but how else can they be used?

Are the holes(where the screw is clamped) in your screw holder threaded?

Informative and entertaining as are all Oxtoolco videos. Is their some benefit to these over the wiggler type? Or is this just an example of how they did it before?

Nice a lot of little machining tip's but I have to admit that Bozo move made me smile for some reason great way to start a day thank you did you make that little screw holder to sand the threads off never seen one before.

Do you prefer the run in saws to the horizontals? What are these edge finders for? Please don't say finding edges.... What's the advantage to a vertical belt sander? I'm used to flat or disc, but I've used both and feel safer on the flat sander. How do you grind the inside faces? Love the videos! 👍👍

Another really nice video and some great camera shots. Why this method for finding the edges of a vise jaw rather than an edge finder, especially an electronic one?

When that first tap let you down and you switched it out; you didn't seem to try and match up the threads when you continued the tapping. Did the mill just do it or were the first few threads "chowdered" as you would say? I grew up in Hawai'i so "mo bettah" is quite familiar to me!

Tom, really love the old lay out stuff !! I have been using a number of those marvel saws for over 40 years, along with others. Now that you have had yours for awhile, how do you like it? Thanks for some more great entertainment. Your friend here in southwest Michigan, Cliff

Nice video Tom. Are there any of this style edge finder that incorporate a hole rather than a slot?

i see you have rubber bands holding your parallels in. ever though about a parallel seperator?

Adam mentions this on SNS and poof in to my recommended...

👍.

Interesting little pieces. How do you use them on round stock though? :-)

Any particular reason for nibbling back and forth taking 0.01" passes instead of one 0.25" pass?

I have seen many of your flea-market finds used. Interrogatory,do you ever lap the flats on those with right angles before using them.

Hidden surface removal is hard :-)

Tom, What's the angled face on the Prait Whitney type used for? The one piece design looks good for a wire EDM. Heat treat a bar than wire cut them out. I may make some.

Hey keep those cubes for a machinist dice project... :-)

Hi Tom, I see you made the edge finders out of A2. Are you aware of DC-53? It cost the same as A2 but has wear better than D2 and the strength of 01 at the right draw back. Many of my homemade tools are of A2 and I love the steel but now I use a lot more DC-53. I look at DC-53 as D2 on steroids. On some of our videos I still use A2 because I have a lot of it laying around. Steve

Does guacamole make good thread tap cutting lube?

10:25 i caught myself blowing on my screen to try and get rid of that little pile of chips...har har har

5:58 Was wondering if the ocd was going to get the better of you or not. ;0) I personally was dying.

Tom is there a design for a corner chair edge finder to eliminate locating zero on two axis?

A GOOD TOOLMAKER KNOWS TO MILL TOWARDS THE FIXED BACK JAW ON THE VISE NOT TOWARDS THE "FLOATING" VISE JAW,,,

can i use some of you ideas to use in my final project

Cant figure out how it works.

Was that Mozart trying to get through at 6:33 or an internet artifact?

Hi Tom

Oh boy.. Tom using actual liquid Sharpie?!

I have to say I cringe every time you run a tap in the mill. As always great lessons.

how long until youtube demonetizes this video because of the classical music in the background... :(

What????.....another way to find an edge....I've used the round type with a 4mm diam tip for yonks.....who really needs another edge finder when you can quickly get as close as .01mm.....sometimes I think some people are just too pedantic for words.
