Lathe Tool Grinding Fixture
HTML-код
- Опубликовано: 23 окт 2021
- I wanted a fixture for grinding lathe tool bits, and espcially single point threading tools, with some degree of precision on my surface grinder. These cast iron brackets from my pile of rusty junk seemed like a good base for it. Another scrap metal upcycle build. Maybe now I can make that lead screw I need?

I promise I'll still mostly make stuff out of rusty junk and not just buy shiny things with your money.

That whole preamble thing at the beginning, I have never felt such a connection with a total stranger, turns out I'm not alone in this.
Indeed, I know what is the yak shaving phenomenon. I think I live in it every day.
What is the term for a circular yak shaving? Like you need a perfectly flat surface to balance the wheel of your surface grinder, but for that you need a balanced wheel to have a perfectly flat surface…. Which opens another yack shaving tree.
Holy Cow, I've been in this business a long time. I can't remember how to do change gears. Thank you for the reminder.
Your project is great and useful, has great presentation and shows great machining skills.
I love it.
Without criticizing, because I'm not, I would only suggest grind or otherwise knock the rust and scale off anything before machining.
There is nothing more abrasive on tools than rust and other oxides.
Thank you for the vid.
I love your ability to repurpose old rusty stuff and showing people that we can reuse many things rather than throwing them away.
I can start out making a hydraulic Jack gland and end up putting a light switch on the work bench, lol, but it's all part of the process, great video, keep'um coming..
When I watch you make something useful with junk I remind my SO that the stuff accumulating in my garage really does have potential.
Very interesting project, Jeremy! And yes, I've shaved many a Yak in my shop (around here, it's called a "normal project"). 😂
Very clever. Nicely done. Some satisfaction out of accurate tool grinding
I’ll be coming back to this later on. .
Love seeing the old Machinary getting put to good use ! Fantastic. And I’m learning along the way.
BRB.
I love your use of rusty junk. That tap holder is taking to the extreme. Love it.
Nice to see someone else who uses my favorite kind of materials scraptonium, mystery metal and wore out old bolts which make good smaller bolts and pins. At the cost of materials i always root through my scraptonium and mystery metal piles first unless it's something critical that requires something special not much goes to waste here. I usually have a lot more buckets of chips vs unusable scrap lol. Good job at showing good use of scraps 🤔🤔👍👍👍👍
Machining is making the tools, that make the tools that make the tool.
Finally I know that I’m not alone in the world. 😂 comrade, friend cheers 🍻 to Yak Shears!
Amazing. Good, clear footage and fun to watch you make something cool! Looking forward to seeing more of your projects.
While the footage is clear, it could use some more description and maybe less video.
Turned out very well Jeremy, thanks for sharing,
Cheers
gday jeremy just found your channel and i like the way you make things from scrap i do the same because new material costs more than scrap and like a good artisan the new part is in there you just have to dig it out i'am now
another subscriber to your channel keep up the good work looking forward to more videos cheers from australia wayne
So that's where all this yak's hair comes from!! Nice work!!!👊😊
Great work. You're making that old iron happy.
Love it! Makes me want to get in the shop and make some parts!
I really enjoyed your project. That’s a great build!
good job thanks for taking you time to show us
You just explained my home hobby shop experience haha
Yak Shaving. I googled it and found it was a programming term? Ive been doing programming for 6 years and never heard that. Learn a new thing every day.
Good work as usual. We shared this video on our homemade tools forum this week :)
Great project and video. If I could make a suggestion, the starting material seems to be cast. Which is great material but the flex needed to lock fixture when finished is better suited to mild steel. The locking knurled end fixing may be better suited by milling a hex so a socket or spanner could be used to apply nessasary holding pressure. However I think the finished piece is very good and will definitely be following your design. Great video
You can use some Belleville washers under those knurled knobs to adjust the pressure to tighten the fixture. Work out the tolerances ahead of time and you can avoid having to flex the fixture to clamp it and still allow for smooth and free movement when knobs release.
Yak Shaving. Definitely gonna use that! As in I've plans to one day carve a Bible box. That entails grinding some hand made carving tools. That requires me to finish a belt sander that I started. To do that I bought a bigger metal lathe. Oh yeah definitely Yak Shaving!
Iv been ill for days and sharpen the yak sheers had me in tears
The longest Yak shaving i’ve ever done started at one end wanting to make a viking shield, and eventually involved making hand forged tools to make hand made nails. I really gotta get easier and cheeper hobbies.
Great project
Just found your channel and liked and subscribe. I like how you think and use what you have to make your projects.
I love these videos Jeremy. And congrats on 400 subs. I predict that will grow quickly!
I just got to you channel, watched s couple of videos, your work is awesome. Both the projects and the videomaking. You’re a kind of thisyoungtony. Wishing you the best of luck and success in your endeavors. I’m sure in no time you’ll be hitting those big subs figures!
Nice fixture you made there.
Enjoyed the content
Pretty neat.
I like what your making and how your making it so have subscribed and hit notifications.
I guess you don't realise how lucky you are to have a 'bunch of junk' laying around.
In my part of Florida, 'scrappers' have picked everything useful so we have to buy new materials and shipping pretty much doubles the price.
(I'm retired and pretty broke)
Got as far as the first 40 seconds of commentary…🤣😂🤣😂
Awesome!!!🤣😂🤣
good job jeremy
Классная работа!!!
wroughts both a joy and potential heartbreak. lil random clumps o hardstuff can drive me bonkers
oh brother i feel ya...make the thing to make the thing to do the project is basically the definition of blacksmithing lol
Very nice your elements how to use and making
Like your work Jeremy
Nice to see you here Zvonimir. He’s like you in many ways
One of these years you need to get that stuck tool out of your mill. Mr. Pete has a video on whats wrong there...... *Ducks Jeremy throwing things*
Good job
You have such odd tools and ways of doing things. I think I'll subscribe.
It is a huge skill, or maybe talent to be able to look at some rusty pieces of stuff and envisage the end product hidden inside without drawings to reference. Only working from drawings is very limiting, but not everybody can do that.
Muy buen dispositivo maestro 👍
One project means 16 other projects or repairs, by the time you get those done, you've lost track of what the original project was. Had something similar to that this past summer... I think the turn around point was in coming up with a fix for the tap switch in the old tombstone welder ... from re-purposed materials.
I've ground bits for my shaper on my surface grinder before, using a small mill vise and Inclinometer. Works for getting the angle right, but limited in that I had to grind in the relief by hand. A good way to mess up the work you did on the surface grinder. I like the simplicity of your grinding jig, I'll certainly put what I can of that idea to good use later on.
On your next bit holder, you might try to integrate a few reference surfaces on it, so you can use angle blocks for quicker/dirtier setups. Just an idea.
Nice ...💯
Excellent Job 👍🇵🇰♥️
Thanks sir
Very cool. I need to design and build a Work Head for a Tool and Cutter grinder. Maybe you can make one so I can see how to do it !
You need to look up Speeds and feeds for the Material and the tooling in Machinery's Handbook.
Get a used one for 10 or 15 bucks USD.
The first 30 seconds....TRUTH
Nice Job ! were do You find such cool cast iron castings
Thank you
Hi Jeremy, thanks for an entertaining video. One thing I would ask of you please, if possible, can you bring your audio level up. Both devices that I watch videos on are maxed out on yours and there are times when I can hardly hear you. Thanks.
How do you keep finding all that old cast iron stuff you use all the time. Where I live, any kind of old metal that could be used to make anything out of had been hauled off for scrap metal.
seasoned Yak shearer here too ...high five. looks like a useful bit of kit, do you think that kind of setup would work with a bench grinder?
Kind of like; It's hard to remember that all you wanted to do was drain the swamp when you're up to your arse in alligators. I often find myself up to my arse in alligators.
Nice, finding diamonds in the rough.
How do you "lock down" your lathe tool post at 5:15? I have the identical lathe (1945 Logan with a QCTP - and worn 4-jaw screw heads, just for good measure), and chatter is killing me for surface finish.
p.s. once you make your new leadscrew, it is the same ACME 3/4-8 as the jaw screws, just by the way.
I just didn’t have the handle on the tool post “closed.”
I’ve got to make a rotary broach so I can make new screws for the 4-jaw, and I probably need to do it sooner rather than later.
What was all the gear changing about?
I use things laying around also including bolts. Looks like you had the right combo of things needed for your build. Like how your mind works. Sorry but hard of hearing, what type of calculator did you use for the angle?
Here’s the link to the one I use, I’ll also add it to the description: www.calculator.net/right-triangle-calculator.html
@@JeremyMakesThings Thank you.
👍
Yes, I *can* use a lathe tool sharpening fixture.
This one looks likely, so far.
Gewindeschneiden auf der Drehbank , mit dem Gewindeschneider - Drehende Spitze gegen den Gewindeschneider und per Hand den Reitstock mit leichten Druck in den Gewindegang zwingen , während die Drehbank auf langsammste Stufe dreht . Man dreht nicht per Hand, sondern mit langsamer Geschwindigkeit und Öl - 4:50min im video
Make yourself a larger chuck key youll thank yourself :)
If I do that, I should probably make new screws for the chuck first, since the heads are stripped out. But to do that I probably need to make a rotary broach, and in order to do that……
Are you really set to pull out the surface grinder every time you need to put an edge on your cutting tools?
No, only special occasions. Threading tools and oddball grinds.
@@JeremyMakesThings ya I suppose if one ever get to the point I need a more accurate grind and already had a surface grinder set up, it would be indispensable... But honestly for threading you don't need to be any more precise than a thread gauge will give you, just need to feed at a precise angle.
Yak Shaving?? We call it Shipwrights disease.
I can't believe you didn't build your own boring head. (Out of an old shopping cart you fished out of the river, of course)
Lol, I guess I haven’t found the right shopping cart yet.
holding parts offset in a vice is not good practice. Always clamp with a part of equal width on the opposite side of the vice
ok
That was hard to watch, my yak kept pressing the pause button. Had to put him outside
all those tools, and no idea on how to use taps and dies. 1 turn forward, half a turn back!
Why does you tap handle look like it's been chewed by a dog?

Mystery metal again. You should know what metal you are woking with.
Excellent Job 👍🇵🇰♥️
