When you first started this video I was completely lost, and by the end I thought that is very well explained and a awesome trick I’d never seen and think I could use as well. Thanks again for bringing the knowledge
Great video Joe. Can’t tell you how many journeymen I have worked with that struggle with finding zero with an indicator, even a hole! Please make a video that shows how to check “squareness” of an angle plate with an indicator.
As always, thank you Joe for sharing another fine technique. And more importantly, continue to challenge us to think and use available tools to solve various problems.
Thumbs up to the Lincoln County High School and their teacher for using your videos in their class, That is as good of a compliment as it gets to your videos.
Joe, I enjoy watching your videos man. You have the heart of a teacher. Your video on turning thin parts aswell as the o-ring expansion tool for holding small parts helped me a lot. This comes from a millennial who absolutely hates asking the old guys at the shop for help. Most guys out there who know their stuff regarding machining principles tend to be entitled a**holes who act like they were always machining prodigy's and never made a mistake. Most of the younger generation of machinist really appreciate the old guys like yourself who offer detailed explanations on principles and why things work. And not just "here do it this way and dont ask why it works because i dont have the patience to help you think for yourself." Anyways a video on reamers would really help out. I had a situation where no matter what I did I couldn't indicate my turnout below .003". Turns out collet was bad. I was stuck for a good hour until I narrowed down the problem.
Good stuff Joe. Years ago, the machinist that mentored me was insistent on me buying a chair type edgefinder. Of course, I bought it, and blew about 100 bux on it, and there it sits in my box, pretty much un-used. I prefer using the method you describe here along with an out of spec gage block.
Love this! The point made about being able to double check location with the dial after the initial pick up (as opposed to using an edge finder), is well made. I certainly see were this method may lend itself to more accuracy. If I could get my guys to watch your channel on a regular basis, it would save me alot of work! Keep up the good work and thank you!
Another great video as usual. I'm a little old and a little slow. You left me in the dust a mile back. I'll have to watch it a few more times. Thanks for sharing with us. Dan
This was absolutely the best(most accurate) way to find an edge that I have seen on youtube to date, and I watch a lot of channels. Thank you very much. I look forward to seeing the rest of your up coming indicator videos.
Joe, Thank you for all the training and advice. I recently retired from a techncal career that never got me close to machining parts , always had to watch how parts was made for me to use. Bought a nice lathe and milling machine . Building Steward casting kit steam engines .. enjoying it!
Joe you have to be one of the best tradesmen I have seen. I’ve also had the advantage of working with a few. Your skill and abilities in the shop are truly amazing.
That's funny. He didn't Even explain that the "shim" must be flat and parallel on both sides. It's a must. Doing this method with a unparallel unflat shim will yield worse results than an edge finder. Basically you must use a gage block. Anything else will not be accurate.
Great video joe very good that your dedicated to supporting every level of knowledge and skill even though it may be just a refresher for some. I applaud your efforts Thank you
Its sometimes hard to judge what is too basic, but then its not basic if you don't know it. There will be some overlap of material, but someone will appreciate it. Thanks for all your comments.
Interesting video and technique, Joe! I always say (mentally) "positive" and "negative" when using the dial indicator with positive being clockwise on the dial. Also, it seems that clockwise, or "positive" always means more pressure against the ball regardless of which side of the ball is being "pressed". Not sure if that is the case on every brand of lever type indicator, however.
I have never had to do this but something similar quite often, finding the centre of a large shaft by touching up top and bottom and splitting the difference in readings in table travel so the dial test indicator reads the same top and bottom. It would be nice to have the luxury of an electronic edge finder that does not have to turn! A cheat lazy-man way on the dial test indicator system is to create a step equal to the radius of the edge finder with two gauge blocks which means the spindle is parked over the edge!
Tom L has a video about what he called "chair" type edge finders, which is a little block that registers against the edge of your work, and has a slot that you can center the axis on using a DTI. Then if you know where the slot is in relation to the edge, typically you would want it centered but there's no reason it has to be, you have your spindle located with respect to the work. It's a similar principle as what's shown in the video, but probably a bit more convenient if you do a lot of edge finding, also if the tool is accurately centered you don't need to worry about getting an accurate offset with the dials
Now with that known zero on the dial indicator, you can measure any edge location on your machined part with using the digital readout. keep watching Joe's videos and he will show you many more. It is possible even on a milling machine to accurately pick up an edge as close as the digital readout will repeat to ' the resolution of the readout'. good video Joe.
@@joepie221 yes. With the rotary encoders on the Moore jig gender that we had,the most accurate was still just dialing in one direction. Playing with 'tenth' dimensions.
Hey Joe, GM required this technique to pick up edges for mill work. Edge finders were forbidden due to inaccuracies. The method seems clumsy until you have done it a couple of times. Im glad you used the "shim" when you were on you last pickup. I actually keep a hardened block inside my interapid indicator case, thanks Joe Mike - Plus8Precision
@@Plus8Precision I am assuming you mean General Motors in an engineering development shop enviroment here. If you are being relied upon to make high tolerance parts for prototypes then I can assume you (you is a general term here) have the skill level required to produce a chair accurate to .0001. Did they allow shop made angle plates? Parallels? Vices? Sine Bars? Vee Blocks? A chair isn't that difficult. Especially if it is made in two pieces
@@mpetersen6 Yes, General Motors, first I didn’t say i agreed with the technique I said that’s what they required. And this was at a tool and die shop where the tightest tolerance held would be .001". This die shop produced large class “A” surface dies. It was definitely over kill for this type of die work. And it faded fast as a process for picking up edges or “J” corners. Processes come and go, somebody maybe an engineer says that this accuracy is needed so it’s done for a while or until that engineer moves on to another job. Then everybody goes back to business as usual. Doing what is needed to get and accurate pick-up on a detail. Back in the day Jig bores and Jig grinders were the most accurate machine tools in the shops. And what was used to pick up the details on those machines chairs. The machine intensive strategies used in today’s tool and die shops is dominated by CNC. Mike - Plus8Precision
Great video Joe. You should mention (if it isn't already obvious) that the side edge needs to be a finished surface and vertical. The closer the ball of the indicator is to the top plane when indicating either the true or projected surface, the less critical a true vertical surface becomes.
10:01 I've got an idea for perfect alignment. 1) Draw a line in the middle of the tape first (on the tape-roll itself, can be done by hand or by bending a ruler), 2) Cut off a piece of tape to cover both pieces to mark, 3 Cut the tape between the pieces with a razerblade/stanleyknife. Thanks for sharing and teaching your skills!
Have you ever heard of a “machinist’s chair”? Hard to describe it but it can be held against the ‘inside back’ against a machined edge with the ‘legs’ sticking up. The ‘legs’ are two solid surfaces that are precisely ground to be both parallel to the ‘inside back’ and equidistant from it. You can tram the two inside surfaces of the ‘legs’ to precisely pick up the edge.
Chris Stephens I think it was something SPI sold at one point (80’s - 90’s). It was kinda pricey due the size of it so I only knew one tool maker who had one though a couple of guys made their own. Do you have a link for the item you mentioned? I hadn’t heard of it.
Not so much when indicating but when milling it is important to be mindful of backlash so that the forces of machining are in the opposite direction you moved the table last. In other words always feeding the table towards your tool not away.
Joe,Just found your excellent channel. Great information. Can I ask you what brand is your magnetic dial test indicator holder (the one with the L shaped round rod and magnetic base). So much better than anything I can find. Keep up the good work
Great content Joe and thats great that a school uses examples of techniques that you use. You sure you didn't have an earthquake when stuff was falling lol that's how my day was
You have helped me inprove my technick a 150 %. Thanks for sharing your knowledge. I now have a question about my chushman 3 jaw Chuck, the scroll part of the Jaws are flush with the hard Jaws,is this acceptable or should they be recsecd, The Jaws are Bell mouted and I am getting ready to grind the.
@@phillipfilkins5627 Thank you for the compliment. If I had any advice to offer, I would say not to stay with a job that doesn't offer diversity or challenge you personally. Time flies by and to waste 20 years in the same place doing the same thing, will only make you good at that one thing. Mix it up, keep an open mind and learn something new every day, and don't settle for a plain job if you don't have to. I've focused on prototypes, customs, repairs and tooling for my entire career and it has afforded me many opportunities to develop my skill set. Good luck and make it happen.
In my day the best and only edge finder was a Starrett. the only indicator was the Starrett Last Word then changed to Interapid. Accuracy first speed second. The process explained used to be called Dead Zero.
Am i the only one who desires an oversize test indicator wall clock now? I love quality measuring equipment,i collect older MIJ mitutoyo stuff and have amassed a pretty decent selection to date! A dozen or so calipers mostly dial, full boxed set of mics with standards,depth gauge,bore gauge and a few dial indicators to name just a few.I just grab stuff if it comes up at right price or i need it,being in a metric country makes the imperial stuff dirt cheap,suits me well as i can work with either but have switched to preferring imperial in my older years. I only have one test indicator and its probably my favourite little tool! It was given to me by a retired toolmaker, its a Swiss made Tesa 1/2 thou job.
@@joecnc3341 just measure the clock you will use grab a test indicator to measure once you figure the ratio just upscale the measurements from the indicator. or make a pantograph out of flat bar
@@joecnc3341Joe, did you ever get around to making a set of drawings for the Dial Indicator wall clock? If so where can I get them? Enjoying your videos.
Another Great Video, Joe Pie. What would be interesting to compare - is the accuracy of an edge finder versus the indicator? How close does an indicator really get you? My "gut feel" is probably 0.001"-0.003" - but we might be surprised. That would be interesting to compare
Think about it. Edge finder.....does it kick out at exactly the moment it should? ----does your table move exactly the distance you dial in? Then maybe you're over the edge. Indicator......Sweep until each surface reads the same value or zero. Done. Nothing has to move to the edge because you are already over it. I say the indicator is far more precise than an edge finder.
@@joepie221 - I totally agree with you - the indicator would be the most precise way of finding the edge (and I really appreciate you putting such great videos together showing the proper way to do these things). I guess my point was - How accurate is an edge finder in comparison? Is it typically out 0.001-0.005? or? with a skilled machinist, of course. It would be interesting to know how close an you get on average with an edge finder...
I'm trying to think of a situation where this is better than indicating a chair type edge finder. I guess with the chair you are still transferring your edge and are coupled to the accuracy of the chair.
Mount your dti to a spindle tool and then you can just sweep one side, then the other. Turn the spindle to sweep and reverse sides. No mucking about with any projected planes. This would be for finding dead center. To find a hole do the same but to the inside instead of outside Er collets work well, interapids have a grab bar on the back.
Hi Joe, I never thought of doing this with an indictor, one question when you do the final move at 12:00 minutes in for the 970 should you not go beyond and then return to the measurement to allow for backlash? otherwise your final movement is left to right where every other movement is right to left. Could this explain the 2 thou' discrepancy on your final indication? Good to see your subs steadily climb.
I did with the crank, but it just barely picked up on the indicator. All my moves were in the same direction. The DRO read .9715 and my dial was just over .971. I did say 970 ish. I like to leave the dials loaded up in the direction I expect to move the table. Red Arrow for sure.

Another Great Video, Joe Pie. What would be interesting to compare - is the accuracy of an edge finder versus the indicator? How close does an indicator really get you? My "gut feel" is probably 0.001"-0.003" - but we might be surprised. That would be interesting to compare
Think about it. Edge finder.....does it kick out at exactly the moment it should? ----does your table move exactly the distance you dial in? Then maybe you're over the edge. Indicator......Sweep until each surface reads the same value or zero. Done. Nothing has to move to the edge because you are already over it. I say the indicator is far more precise than an edge finder.
@@joepie221 - I totally agree with you - the indicator would be the most precise way of finding the edge (and I really appreciate you putting such great videos together showing the proper way to do these things). I guess my point was - How accurate is an edge finder in comparison? Is it typically out 0.001-0.005? or? with a skilled machinist, of course. It would be interesting to know how close an you get on average with an edge finder...
Hi Joe, I liked your indicator clock so much I decided to make one of my own. I would have sent a picture of it, but I am not sure how to send it.
Its a fun clock to have on the wall.
great lesson give example edge finder accuracy for comparison please
Great content, Joe! Hook 'em Horns! :D
I'm trying to think of a situation where this is better than indicating a chair type edge finder. I guess with the chair you are still transferring your edge and are coupled to the accuracy of the chair.
Mount your dti to a spindle tool and then you can just sweep one side, then the other. Turn the spindle to sweep and reverse sides.
No mucking about with any projected planes.
This would be for finding dead center. To find a hole do the same but to the inside instead of outside
Er collets work well, interapids have a grab bar on the back.
Respectfully, your suggestion won't work when trying to pick up an edge as the video title suggests.
Hi Joe, I never thought of doing this with an indictor, one question when you do the final move at 12:00 minutes in for the 970 should you not go beyond and then return to the measurement to allow for backlash? otherwise your final movement is left to right where every other movement is right to left. Could this explain the 2 thou' discrepancy on your final indication?
Good to see your subs steadily climb.
I did with the crank, but it just barely picked up on the indicator. All my moves were in the same direction. The DRO read .9715 and my dial was just over .971. I did say 970 ish. I like to leave the dials loaded up in the direction I expect to move the table. Red Arrow for sure.
This is exactly the way I split tenths on a jig grinder.
Pie r square? No, Pie r not square, Pie r cool! Thanks Joe Pie! Learning a lot of cool stuff here.
