DRILL POINT GAUGE PROJECT #1 laying out the holes, prick & center punching, drilling small holes

First video of a four part video describing the fabrication of a drill point gauge. This project introduces the novice machinist to several basic machine shop (bench work) operations as well as introducing basic notions on organizing and preparing a project. More specifically this video presents the basic layout of holes, positional punching (prick and center) as well as the drilling of small holes.
As for all THATLAZYMACHINIST videos, this video is produced for novice , garage or beginner machinists. You can find all my videos as well as project drawings and course notes on my website THATLAZYMACHINIST.COM . Thanks for understanding that I am a professional toolmaker and teacher but I am not a professional video producer (and it shows). I produce these videos for fun as a little retirement project that lets me give back a little of what was passed on to me by so many amazing trades people most of whom, sadly, are no longer with us.

Déjà Vu...

[@THATLAZYMACHINIST]

Hi Bob! This project dates from the very beginning of my KZbin adventure. I decided to revisit the video (as I have done with other early videos) in order to resolve or try to resolve some issues with the quality of the videos and upgrade to the new 16:9 format. Younger people watch the videos on their phones and the pill box format (4:3) isn't very good for that. I will also be re editing the part 2 and part 3 of this project video in the days to come. Thanks for watching, Marc

[@duobob]

@@THATLAZYMACHINIST I assumed that was what you were doing. It might be less confusing for some of your audience to just announce it for what it is...

[@THATLAZYMACHINIST]

@@duobob Hi Bob, I have added an opening sentence to the video's description and pined your comment to the start of the list to alert viewers of the remake. Thanks for the input, Marc

[@JosephLorentzen]

The first project I made in shop 50 years ago. Thanks for the memories.

[@OldtimeIronman]

Yay Marc!! One of the clearest teachers out there! (And I love doing bench work, not much choice on my budget)

[@bobvines00]

Marc, thank you for this video. I haven't made any of the projects yet, even though I downloaded the drawings a long time ago. I'll go ahead and print and mark the corrections to the drill point gauge drawing. Then I'll start collecting the materials I need to make the projects. But, I'll need to get my 108-year-old lathe running properly first! I can make this drill point gauge as soon as I get the material, but will have to hold off on the lathe work for a while.

[@glennvandenberg3912]

Thanks Marc. I'm going to make one of these for my tool bag to check my twist drill sharpening efforts. They are generally done free hand on a 125mm grinder on the floor of the job.

[@alasdairhamilton1574]

Many thanks once again 👍👍🏴󠁧󠁢󠁳󠁣󠁴󠁿

[@bassome3000ify]

thank you very much, i learned a lot from your plastic injection molding videos ^^

[@stringmanipulator]

I may sound like a complete idiot by asking this question, but I am a novice ... why the threaded holes? are they only for "practise" or do they have a function? thank you so very much for sharing these awesome videos

[@andreyvolf6217]

Отлично!!! Очень хорошо!!! Нужна вторая часть ?)))

[@johnstark6535]

At 12:19 in the video it seems you have just finished the new reference point b. You took -3/8 from where the 7/8 surface was. If I were to do that for point C would I take 7/8-4/8 to get my new point at -3/4, 3/8? I saw in the blueprint to minus 1/2 at C. Just want to make sure I’m understanding what you’re saying thank you.

[@THATLAZYMACHINIST]

Hi John! I think that you have it but just for maximum clarity (not everyone will understand your question) I will run through it quickly. The holes are positioned in a Cartesian (x,y) grid that has as original Y reference the horizontal line that points H and F are on and the original X reference is the end of the part. Since I decided that the end of the part is going to be even with the end of the blank, all the X dimensions that appear in the hole position chart are use as such, no change required. The problem is with Y, most designers think only of the finished part and the designer knew that the bottom angular line wouldn't be a good reference. That is why the designer decided to put the reference on the H,F line that appears on the print . The machinist cannot use that line as reference since it does not exist at the beginning of the project and we must follow this golden rule of layout and measurement "ALWAYS MEASURE FROM AN EXISTING REFERENCE SURFACE". For the Y dimensions we must adjust the dimensions so that we can measure from a real reference and in this case we have chosen the accurate bottom of the blank part. If I were to measure from the new reference to the original one, It would be 7/8". So the new hole positions in Y will be: Hole A: 7/8"- 1/4" = 5/8" Hole B: 7/8- 3/8" = 1/2" Hole C: 7/8"- 1/2"= 3/8" Hole D: same as hole B Hole E: 7/8 + 1/8: 1" (it is a + because E is above the original reference) holes F and point H are on the original reference so they are 7/8" and finally point G is equal to the large radius so it is 1 1/8". I know from your question that you understood this but I now that many people get confused with reference relocation so this could help them to understand. Thanks for watching and for a great question, Marc. P.S. to everyone out there, you can download all the prints for my school projects from my web page THATLAZYMACHINIST.COM (Teachers can use them and the accompanying videos in class as long as they are not modified) it's all free and always will be.

[@johnstark6535]

Marc, I am going back to take a 300 hour CNC machining course and I have been viewing your videos for tutorials and everything have been very helpful. I understood that you kept the x coordinate the same. If you’re making a new reference point for other shapes would you go about it the same way if you were machining the part manually or through a CNC machine too? I did graduate with a degree in Civil Engineering Technology so I understand blueprint reading a little bit working in the third dimension is gonna take some getting used too any advice on how to improve that faster as well? Thank you very much and I also did catch on to what you did for holes d and e too

[@THATLAZYMACHINIST]

@@johnstark6535 Hi John, for the third dimension, get a box, cut a hole big enough for you hand to fit in, get someone to put a bloc of some sort in the box (keep it very simple at the start, kids play blocs or something). Using one hand to touch the bloc in the box and the other to draw, try to produce a three view projection drawing of the shape. When satisfied, pull bloc from the box and compare with sketch. This forces you to see the part in your mind and gets you use to thinking in 3D. Your eyes can deceive you but your hands will not. I hope this helps, with time you will get quite good.

[@johnstark6535]

Marc, That’s an excellent idea thank you. I also found the bowl exercise very well too

[@TerryVinet]

Could you share a pdf of that drawing? Thanks

[@Video-le9tk]

Sir, you can explain the angle setting

[@dhavibes8280]

Can we have the copy of instruction sheet sir?

[@THATLAZYMACHINIST]

Sure! Send me an E-Mail at [e-mail] and I will return a copy of the instruction sheet. Thanks for watching and for taking the time to write, Marc.

[@ElizabethGreene]

Could you add a link to the print in the description?

[@bobvines00]

Go to www.thatlazymachinist.com/ and click on the "Project Drawings" link. My browser automatically downloaded the complete drawing package for the course. I had to add a ".pdf" extension to the file though, in order to open it.

[@janslos]

Again a good vid, thanks, but ... why are the plans not in metric??? I thought Canada used metric like the UK and almost the rest of the "civilized" world.

[@aceroadholder2185]

Janslos, in the rest of the civilized world machinists secretly covert millimeters to inches so they can make stuff.

[@bobvines00]

Doesn't Marc make a metric version in French? I _think_ that his Thatlazymachinist.com website has the drawings in metric too.

[@janslos]

@@bobvines00 I will check the french version now, thanks, why didn't I think about that

[@janslos]

When you convert inches to metric you get some odd numbers, 5/8" times 2.54 equals 1.5875mm.

[@janslos]

no, also in inches

[@jayayh9650]

Great video as always sir but the sound could use some work. There is a weird sweeping noise when ever you are speaking.
