- Yes, I know he did. Yup. Two of them. All we can do is move forward.
Gears are becoming more and more important in some of the things I'm working on, so I decided to get a little more comfortable with making them. I got a cheap 8 piece gear cutter set, but I couldn't find a straight shank arbour in the duration of my spontaneity, so I had to make that first!

This Old Tony's Gear Video: • Gears! - But Were Afra...
nice work! pro tip: with the right music that washer wobble could've been made to look intentional. ;)
Thanks! Its always the editing that gets me!
☝️🙄This guy Tony.🙄 ☝️
@@TabletopMachineShop Very nice work. What was the project?
I don't know why, but your videos are oddly relaxing and very satisfying to watch. I'm loving it!! Keep em coming!
Thanks! I'm glad to hear it!
turning on a lathe is verry relaxing. (as long as there is no boss breathing down your neck)
I've grown to hate those countersinks too, i think those are for soft material, wood and plastic. Who would know!The best countersinks i find are the ones with the hole drilled at an angle, with the edges of the hole as the cutting faces
I love those ones for deburring!

The one flute countersink is the only thing that works.
This Old Tony waz here 🤣
I have bunch of the 17PH too that I got at auction. Great stuff. I use Cool Tool II. I've had good luck with Ford 6 flute countersinks.
Interesting, do you have to run the 6 flute CS really slow? I just can't seem to get them to work.
better *lathe than never?
Nice looking arbour. My stint at a lathe fast approaches.
Oh i like that!
Never had any luck with multi flute countersinks either. I use a large single flute or the one with a hole drilled at an angle to the center line, can't remember what those are called at the moment but you get the picture. Nice work!
Thanks! Ya I know those "cross drilled" countersinks well.. I like using them for deburring though I don't think I've ever used one for a big countersink
The best gear cutting video I have ever seen⚙⚙⚙
Look at fellows gear shaping and hobbing lots of stuff
Just remember to brush your teeth. ThisOldTony has old man breath. Like my dear ol' Grandpa; Tobacco and cutting oil.
You would want to know the heat treat on the 17-4 stainless before trying to heat treat it. If you are going for a H900 HT and it has already been heat treated to say H1075 or H1150 you can't go to H900 (Its hardest) without a solution anneal first. If you are starting with annealed material you can then go to any heat treat. The solution annealing would probably be out of the scope for a person without special heat treating equipment.
Thanks for the comment! I was going for H1150 from the annealed state ... according to some random website of course :P It seemed to go okay, but like I mentioned it didn't get particularly hard. Heat treating is black magic.
@@TabletopMachineShop I've have good results with making tool holders from 17-4 PH, I know it doesn't stand for "Pre-Hardened" but it does help me remember.
We used 17-4PH a lot on building medical tools for spinal operations.. Nice video
I'd like to get some of those cheap gear cutters .. can think of a lot of uses ... but then Id want several modules and things would get expensive...
I officially ordered another set. I'm promising myself that M0.5, M1 and maybe M2 will handle everything I need.... In hindsight I promise myself things like that all the time and it rarely works out. Oh wellll
yeah those are exactly the sizes I'd go for .. though I had a look recently and they were out of stock on the 0.5 and 1M... and the same sets are more expensive when stocked here in the UK, anyway one day!
what do you mean with conventional cutting??
i only know conventional as "not cnc"
that's what we called our hand operated lathes and mills.
are you using it to indicate the cutting direction here?
You got lucky not finding an arbor, I bought a chinese mt4 22mm stub arbor and it has like 0,05mm runout. Could regrind the morse taper to get it good but that's always extra work
Also, the "south bend" chuck appears to be of really good quality and obviously never crashed into anything
That's funny, I've heard a few people getting these from china and them being the wrong size, out of round or out of concentricity. Buyer beware I guess! Yeah the chuck is beautiful. It's a shared machine, so it's a miracle it hasn't been crashed lol
Nice video Mr. Shop. (Tongue firmly in cheek) Looking forward to seeing the final application of this adventure.
Please, call me Table. Mr. Shop is my father!

Great work. I mess around a little but nothing close to this. I made a small tool post holder and an attachment to fix a center line problem with the compound slide for a Sherline lathe. I uploaded those videos but of course its very amateur compared to this.
Working on making my own dial gauge right now but of course the accuracy would probably be suspect. I will upload that too regardless of how it comes out.
Thanks! I'll check out your video. Have you seen Clickspring? He absolutely slays it on a Sherline lathe, so I wouldn't doubt yourself just because of that!
@@TabletopMachineShop I do not miss a Clickspring. He is an absolute perfectionist. Brilliant work. The antikythera mechanism is really good. I do hope he donates it to a museum after so many more can see the real replica in action.
The 6-flute countersinks require a fairly rigid setup to not chatter. Too light of a feed or too long of a dwell on a rigid setup will chatter as well. I've always had luck with KEO and MA Ford. Neither are too expensive.
It's funny, this is probably the most rigid setup I've ever used and it still chattered. Granted, the tailstock was extended pretty far, but it's a big lathe. I did feed pretty slowly, so maybe that contributed. I do have a 1 flute MA Ford countersink that I love! They make good stuff.
Use helical reamer. If it still chatters, apply Crisco. Old trick.
Not That, is trying his hand at gears. $80 for some cutters is steep. My cheap old Irish self thinks, " thats a few bottles of whiskey and a thirty pack.
I like the keyway idea.
I thought I was the the only one that had no luck with those 6 flute countersink bits
I wonder if there are support groups out there :P
My experiece is not to use is as a countersink, but rather as a chamfer tool for edges, like on a milling machine.
If you want to countersink a hole nicely it is posible if you take the rpm to the absolute lowest setting and feed with dedication :)
I use to have this problem. I found slow and steady is better. If you dive too fast then let off is what causes the hex.
canadian lubricates with maple syrup, russian would use a lard or castor oil
Beautiful video -- I really enjoyed it. What kind of camera are using for the lathe shots and how are you mounting it? It looks like it's mounted to your tool post?
Thanks! So I actually use my iPhone 6 for shop footage, and I mount it on a mag base on the toolpost or tailstock depending what I'm doing. Modern cellphone cameras take beautiful video, you just have to make sure you keep them safe and dry!
Why is this channel called the Tabletop Machine Shop but that lathe looks like a floor model and is huge?
Haha well played. The machines used so far in my videos are at my work, which graciously allows employees to use them for personal projects. I've been designing some much smaller machines that I can run at home, and, when the designs are finished, I'm going to make them!
I haven't found a Chinese 8x16 lathe I am willing to suffer through so I have never gotten one but I check videos, like yours, constantly in hopes a gem emerges. I want a mini mill as well with at least 4 inches of Z travel and 5, or 6, would be optimal.
The Best Stooge maybe he upgraded
@Ya Boi No, as you can see by his reply to me and if he had upgraded then he would need to change the channel's name.
well done!!!
is there a way to calculate the diameter of a gear with a given number of teeth, knowing it's module 1?
Thanks!
The module system makes it easy. You just take your module and multiply it by the number of teeth plus two. So for a 20 tooth module 1 gear, the diameter of the stock is (20+2)*1, which is 22mm
You had to go and make that gear cutting look easy didn't you.
Read somewhere that countersinks with odd number of flutes work best ..
That may be true... I have decent luck with high quality 3 flute countersinks
nice one with the low pass!
Science!
@@TabletopMachineShop apparently it's a well kept secret amongst other youtubers
very nice job!
Thanks!
AWESOME! Is this a mini injection molding auger? Collet closer?
Those sound a lot cooler :(. It's an electromechanical squisher for a silly idea i'm prototyping :P. Details to follow!
Woohoo. Also, speed it up with that Jewelers lathe! Lol
Video soon! Itll probably be done in 2-3 more videos. Its a high priority!
What does "not as hard as an alloy" mean? 17-4 is an alloy with nickel copper and chromium.
Youre totally right, technically every metal I work with is some kind of alloy. When I say alloy, I usually mean a mid to high carbon steel or a high strength low carbon steel alloy like 4140 or 4340 or a tool steel.
Great Job!
Thanks Juan!
Really Wonderful Idea, I'm Happy to Join with your channel, I HOPE TOD MO CAREER
always lick the excess Maple Syrup and wipe with a slice of bread !!
I seem to recall that in lathe safety training one of the first things they said is "don't lick the workpiece" :P
I like this video
Can't help but to feel like you're running quite high RPM... It's probably fine... just feels like way too much :D
In the turning? Probably. Carbide is pretty forgiving though, and I find on this lathe in particular I tend to get a nicer surface finish at high-ish speeds in stainless.
Hi Tony... I mean... Greg. Nice video.
Thanks!
Why do so many TH-cam machinists use cutting oil instead of coolant when drilling etc? Is it so we can see what's happening? Because surely for heat removal etc it's less efficient and chip evacuation is basically non existent.
Also, I understand that in this case brass/bronze is usually machined dry to make swarf more manageable.
I usually use oil on manual machines because coolant can be so messy. It's definitely much worse for heat dissipation and chip evacuation, but it is good for lubricity in drilling. It also tends to stick to the cutting tool to prevent building up material on the surface. The other thing I kind of like about it is that it gives me an idea of temperature of the part based on how it smokes. That's a bit off-label, but I still find it useful. It also looks cool :P
@@TabletopMachineShop cool as, yea coolant can get quite messy.
It certainly works so keep on doing it!
nice work , im watching you here in " la negreta "
Thanks for watching! Is that in Spain?
Hi. Great video. Going to get some 17-4 PH steel soon to try it. Could you please tell me what Make and part numer of square inserts youv'e uset for chamfering. I struggle to get ones with sharp cutting edge for steel. Thanks.
Thanks Jerzy!
The inserts are high polish SCGX inserts. They're for aluminum, but they leave an amazing surface finish on just about anything. The trick is that they have a high-positive rake angle so they're very delicate. Here's an example: www.shars.com/products/indexable-cutting/indexable-inserts/scgx-32-51-lh-yd101-1-carbide-insert
it really irritates me when someone is using a micrometer and then just keeps rotating the free bit (the clicky bit)
yes i get it you need to get it propperly angled.
but you are also messing with your measurement if it was already perfectly flat.
(most often i see this with calipers though but hey)
14:25 noooo, poor teeth. so sad :(
If only use Canadian syrup also only coolant from Texas cows milk
And European Absinthe for tapping aluminum!
9:07 the hell was that a solidification void?
Somebody forgot part of their drill it in :P
Aaahh 😆
Piece of a broken center drill looks like.
This seems familiar
Deja view?

nice video welldone......
thanks Steven!
I'm so confused. Your words say imperial but your accent says metric. What aboot that?
I'm bilingual! I officially converted to designing things in metric a few years ago but I occasionally flip flop haha
Tabletop Machine Shop what ever language is spoken this great work!
Nice work. I subscribed to your channel willingly.
Thanks Eihab!
Nice video, but you should have called it making an arbor, as most of it was nothing to do with cutting gears, sorry , but thumbs down on this. Colin.
Sorry to hear that! The video was definitely on the arbor heavy side, but it was my first experience cutting gears, I just had to get ready first
