DIY Knurling Tool

- Here I make an alternative knurling tool for the taig lathe. Normally a tool like this generates an enormous amount of side pressure so I went with a little different method to build this tool.

A very clean knurl, and plenty deep. It's great to see people come at things from a different direction, and even better when it works so well. BTW I have a heavy blue marker that came with one of those knife sharpening kits, and it is what I now use for most of my bluing for marking. No mess, and does the job.
It always amazes me that work like that can be done on such a small lathe.
All the best.
Awesome Fabrication - fabulous presentation.
Excellent! Glad to see young people so interested in the machining arts. A good machinist, is also: a designer, an engineer, a metallurgist, a blacksmith, and a metrologist. You have a good future ahead of you.
Thanks for the kind words my friend!
I absolutely love these videos! Keep them coming!
Nice project. Gave me an idea on how to remake the junk knurling tool i purchased. Subscribed
I'm going to work my way slowly through your back catalog!
Nice design and execution--thanks for posting.
Just got myself a Taig last weekend, and have already been thinking about a knurling tool. That looks really nice. I may have to get the guy I bought it from to make me one (already have quick change toolpost, er25 collet chuck, variable speed, and variable speed reversing lead screw)
Excellent! Thank you for sharing!
Nice build. I like it better than mine, which is just a push in after mounting it on the tool post. Thanks for sharing. Best Wishes n Blessings. Keith
Great idea, may try this on my Myford 7.
Great design and execution, thanks for the video.
Thank-you for the comment!
Really nice work. And the video quality and explanation is excellent. Keep it up!
That is a coool idea ....Once again another great project to make
Great work, I can't believe it took me this long to come across this vid and your channel!
Thanks for the kind words.
Awesome vid thanks for the info!!
Clever idea for a small lathe or for small parts that can't take the pressure of a single knurl pushing on the side
Awesome work! I'm just starting to get a grip on learning my Taig lathe. I like your design more than the bump style knurlers! I'd love to see more taig videos, like the tool post height adjustment you mentioned. Also some info on your indexing plate. Thanks!
+Casey Ryan Thanks! I'll work on getting the taig update video posted sooner then later, also thanks for the sub!
Brilliant!
LOL! "You can only watch people drill holes for so long before it becomes boring." Didn't see that one coming. :-)
Nice result.
awesome work
Coool set up man!
Very nice!
Great idea
Eye balling accounts for most of the scrapped parts in my experience, you were damn lucky there. Denatured alcohol is the best lubricant for aluminum. WD40 is good too, and more practical.
wrong.
good job
nice one👍👍
nice work, but unfortunately it is not really clear how you bolt down the blocks to the table, how the bolt work with the key?
that is amazing.
+Martin Thanks!
There's an alternative to the standard layout fluid if you aren't using coolant or oils when you cut: Pilot markers. They make a large size blue marker that works like Dykem, but it's faster and cleaner to apply. Dries in seconds. Only problem is that coolants and WD40 will wash it off, making a bit of a mess. If you don't use those, it's a good alternative. I found the makers on Amazon. They come in other colors of course, like red and green, but blue works best for me on aluminum.
Nice work on the knurler!

+BigMjolnir Thanks for the tip!
+Curt Filipowski You're welcome. Just passing it along...I got it from Chuck at Outsidescrewball. There's a huge amount of good info on UA-cam because folks like you and Chuck and lots of others share what you know.
Whats the blue dye called?
I've been looking at this again as I have a project that will need a knurl. What I am finding is that a pair of knurl wheels cost about the same as complete, clamp type, knurling tool. In fact it would cost me more to make one by the time you factor in the other materials.
Yep, that about sums it up. At the time I couldn't find a knurling tool that would fit the taig well so I had to go the diy route...now there are plenty options in that size point.
which lathe are you using?
Good
Hello, what is the name of this tool 4:51 and is it on aliexpress?
A "left" and a "right" are required for a diamond knurl, correct? I see Grainger's has some Dorian wheels on clearance right now...
Indeed.
Try making a knurler with the wheels off lighters?
What are you using to apply oil when milling? Great video!
Thanks, I'm using a cheap plastic 3in1 oil bottle from years ago...leaks oil everywhere but keeps my table from rusting :).
i like..
mighta been nice if you'd shown the finished project working at the beginning for some of us to get the idea and then others could watch it all the way through to see how holes are drilled. Good project though, thanks
Good suggestion, I'll try and do that in future videos. Thanks for the comment.
You reinvented the wheel
So tell me, does knurling Push/Compress the metal out of the way or cut it out of the way?
...And if it pushes/compresses the metal, will it make the circumference slightly larger?
Yes, in this case it deforms the metal to size. There is also cut knurling that does exactly what it sound like. With this style you are also correct as the diameter increases. An old (kinda hacky) trick to make a shaft that's too small/worn fit tightly into a bore is to slightly knurl the end to bring it back up to size.
@@CurtVanFilipowski Thank You. That last part you say is why I came to your video. I have a crankshaft snout, 4340 steel, that is a tad bit too small. The timing gear and damper slip on instead of press fit. I'm exploring the possibility of Knurling as a cure.
Excellent Video, take an orange out of the bag for ingenuity,

Thanks for the kind words, I must have watched your tool post video 10 times while trying to come up with ideas.
Aren't there specific diameters that each knurl handles?
Yes and no...in theory a wheel size will knurl in stepped sizes (multiples of the tooth pitch over the circumference of the stock), however that goes out the window once you change the tool pressure (depth of knurl).
4:38 hmmm, that looks exactly like the scriber of clickspring...
You bet! One of my favorite youtubers!
Curt Filipowski nice! XDDDD
what brand and model lathe and mill are these?
He stated this in other comment:
"The mill is a clone of a G0704 (craftex CX601)."
Hope this helped ;)
Where did you get the wheelers?
theyre all over ebay
Ok, I'm excited. There's no way I can do this BUT it's one step closer to what I'm hoping to find: I need a hand powered machine that's portable, with which I can put a knurl on the edge of an Eisenhower dollar. I'm a magician and I gave my coins to a machinist to have the reeding (milling) recut and he misunderstood and knurled them instead...and they were 1000% better! They do get dull and I have to repeat the process which isn't cost effective or exciting for him. Does anyone have any ideas? The search has been like tracking Bigfoot!
Neat application! I would vote a clamp style knurling tool and then get the the front part of the tool made with an integrated steel shaft and flat "super glue" chuck to mount your coins to. Put a hand crank on the back and let the the knurls float on a single pivot so alignment isn't an issue...far easier to drawn then explain so if you are seriously looking to solve this problem shoot me an email, I'd be happy to lend a hand (www.confoundedmachine.com, there is a contact form on my site).
Why do you need a DRO? We developed nuclear weapons, and went to space without them. The cost of installing a DRO on my lathe would be a good down payment on a mill. I like your knurler, one of the better types I watched being built. This is similar to how an old B&S turret lathe knurling tool worked.
Need is a strong word...want is more appropriate. Thanks for the comment!
what mill is this
The mill is a clone of a G0704 (craftex CX601).
ouch! using calipers to scribe? good stuff tho we all have to make tools we don't want to buy haha
I know...its just so damn convenient (that and they are an inexpensive variant). Thanks for the comment :)!
what mill do you use?
Basically a clone of G0704
what mill and what lathe would you recommend to start with?
btw i live in new zealand
ワオ 手送りでできるんだ！

A large blue magic marker is simpler and available anywhere. You don’t need to buy special marking blue.
Great, I search for how to make a knurling cutter, and it needs a bought knurling cutter.
Facepalm.
You could very carefully cut the striations into a steel blank (rotary tool, file, etc) and then harden...wouldn't be as robust as a commercial purchased knurl cutter but there is always another way :).
