your effort into the camera angles is awesome, makes ya really feel as if your right on the subject and not some distant tripod view.. keep at it brother, love watching your content.. Much love from an American machinist.
G'day Max. The 3 MT adapter worked out really well, but ... looking at the Coventry Die cutting the thread, then opening up to stop cutting at the exact marked point is very Impressive. Well Done, & a Very Professional Tool.
@@number2664 Hey , no worries thanks . There are a few bits missing for the capstan slide apron . I will look in my parts book when i get time . My email is theswanvalleymachineshop@gmail.com
That tailstock adapter is a good idea. I need to make one. I run my die heads in boring bar holders on the tool post like Keith Fenner demonstrated a while ago. Stopping against the carriage looks easier than my current process of running to a zero on the DRO.
I have a small die head I will have to put on the list of things to do and collect the smaller common threads Also Ended up with some larger thread chasers Thanks top video as aways.
Great video Max. Acquired one of those years ago in a box of bits that I bought. Never understood how they worked until you just explained it. I’ll go out and have another look now but as you say, without the dies it’s a bit like having a car without wheels…………
Hey mate you are on par with Matty's Workshop for making me piss my pants with your one liners. Great aussie slang, love it . Cheers from Mt Hawthorn, Perth .
Great video Max! I'd never known what these were called till now. They're similar to the dies I'd use on a pipe threading machine at a factory. Lol I can still smell the toluene we'd use to clean off the cutting oil.
Amazing how similar AUS. Is to where I live in South Africa. We also haven't had a winter yet, still swimming at 06h30! No rain in month either, not expecting any until Oct/ Nov.
I can send you some rain. We have had a lot over the last 2 weeks. Probably 5 to 6 inches. Everything is green and growing strong being we are in late spring here.
Hi Max I'm a hobbyist from the UK and your channel is very informative. I enjoy watching and learning from you. Thank you for all your effort. You mentioned in this video that you honed the ball mill before you used it but unfortunately you didn't show how? If possible could you show how you hone your tools. If I have missed a video that you have done so already could you point me in that direction. Many thanks and please keep up the great videos. Dazzer. 👍
That was very interesting. I've never used die heads, the guys on capstans were very jealous that they knew something 'we' didn't. I do have a set of 1/8" Whitworth chasers I bought for some reason but so long ago I forget what I needed them for (a 'Saturday morning special') I was more into British bikes back then, even though I had a Honda to get back and fore to work. Only Vincent's and Brough Superiors were collectible classics (probably others I can't remember) BSA, Triumph and Norton's were mainly just old leaky bikes rusting in back yards. Wish I had a few nowadays though seeing the crazy prices they go for.
@@swanvalleymachineshop Hi Max, I was working at a Honda, Yamaha, Triumph dealers when the Jubilee Bonneville was launched. We had one come back where they 'forgot' to put circlips in piston one side and gudgeon pin wore a slot between cylinders. Very difficult to get apart. Almost all of them came back for faulty chrome. Meridan wasn't doing a very good job. A friend was racing a Bonneville with Weslake 8 valve top end though, said being passed by Kawasaki Zed's' at over 130 was depressing after all the work he put into it. Did go around corners better than the Kawi's though. Until about 1998, I worked on various 'old' Triumphs every few years, when running right they are really good fun, the low speed torque was great, particularly in traffic (much better than Yamaha's XS650 in my opinion)
I wonder what the guts of that head looks like. I'll have to see if I can find some patent drawings and decide if it's something that can reasonably be shop made. Great job on the video, as usual!
I had this one apart but did not film it . I should video the strip down & clean of one of the other ones . It could be made , but would be more than a tad tricky ! Everything is hardened & ground so it will last . Cheers . 👍
To secure a contract from Coventry fasteners is a machinist dream job. Avoided nut & bolt section as apprentice & chose fitting. Did use a turret & robotic instincts can cause problems if finger are not careful. True thread eater all my experience was done at the Haros Boiler Company. They were a great start in a new state. Definate showing that a run of threaded parts is no problem for Max's shop.
Now that is the way you can bang out some threads! Always knew that something like that existed, but it’s the first time I’ve seen one in operation. Single pointing films great, but if you have to do five or fifteen of the same size and pitch…….😮. I’m guessing that retail is stiff for setting up initially, but what a tool! Thanks Max
Great job Max! I love those Coventry style geometric die heads. My late brother was a precision thread grinder, apprenticed at the firm of LAL ( Lehman, Archer and Lane) literally a mile and a half down the road from me, I think they made thread chasing dies but I'm not exactly sure. Sadly the firm went under in the early 90's like so many British engineering companies did around that time. I love your work and Aussie humour and as someone else commented it's on a par with Matty's from Matty's workshop from beautiful Eden. Keep the vids coming Max, they're really good to watch and are extremely informative. Cheers from England, Sam
Micro 100 was founded and based in my hometown Meridian Idaho USA. It’s great that products from a small town being used on the other side of the world. My dad repaired the machine that soldered that carbide to that shank.
@@swanvalleymachineshopI have a couple of their carbide end mills and a small carbide boring bar that have held up rather well. I love your content keep it coming.
G'day Max, just up on Sunday morning, fresh coffee and a video from you, happy days! Thanks for sharing buddy and best wishes to you and yours Edit: Having watched this, I have to say what a job well done mate, lovely stuff
We have had 2 days consecutive with no rain here on the mid north coast of NSW, I have several of those die heads and a box of dies, one day I will get around to working out how to use them. You have explained it better than a lot of other videos I have watched, I feel I could now attempt using them, a lot are just thrown in a box, I do have some boxed sets
for the benefit of those that haven't or cannot visit Max's Machine Shop - the fast forward segments are actually His real speed ! 💥, Max only slows down while speaking and thinking
If you want some rain Max, you can have some of ours. Its done nothing but piss down here in Yorkshire, UK, for about the last 18 months. Though the last week we have seen 21C and some sun, almost forgotten what the sun was. Another lovely little job done again. Really must try and find some decent 2nd hand tapping and die heads.
Thanks Max I have a 1/2” CH head I am restoring, I hope yours don’t use oddball threads like my Herbert eg the front plate is retained by under nominal dia. 3BA. I need to make an arbor like yours so this was very useful.
Nice job on the adapter...a bit of relief from funky lever curve's, angles and internal slots 😁 Yeah no kidding those die heads are not cheap, had to pass on a couple..just too pricy
Hi Max, we are screaming out for the wet season to start here in Philippines, currently in drought conditions. The die head produces an excellent finish and cuts to an accurate length, easy as.
Lol . I did not forget , just left it out to save time as the video was more about the die head than cutting a Morse taper . I will show the next Morse taper set up ! 👍
Hi Max, Nice video as always. I was trying to find a decent Capstan lathe in the UK just recently, with absolutely no luck, as soon as one comes up for sale its snapped up. Great machines for turning multiple parts especially where you have a long threaded section. CNC's are great but have their limitations. Best wishes, Mal. PS: hope you get some rain soon.
Another fascinating video Max.👍👍👍 If you do ever have a DRO scale on your cross slide on the small lathe, and still wanted to use the Coventry style die head you could just drill and tap the side of the slide below the scale cover and screw a machined shoulder bolt stop in a fraction proud of the scale cover as your new stop - to protect the scale cover from potentially being crushed. Alternately you could fit the stop to the front of the base of the tailstock & position it so it hits the side of the cross slide below the scale height. Either / or should work. My AL 356V has it on the cross slide I recently noticed, so not my idea. I’m not that bright. 😜😂😂😉
> nice work there max; looks like a handy piece of kit those thread chasing sets. its been many years, the engineering dept i worked in - we got issued paper copies of the mcmaster carr catalogs (like 4"" thick). im sure most of it is online; always enjoyed the materials research, application and specification pages. ? do they have outlets in austrailia? my opinion reading book pages corresponding to whats being looked up in the pages might be a lot easier than how stuff gets cataloged online....maybe if requested they will send you the latest edition .
Thanks . The big catalogue books were great . But like everything else , it's on line . But at least that way , it should be reasonably up to date . McMaster do not ship to Australia so i use an American forwarding address . Cheers 👍
I think you mentioned that the shank on the die head is removable. Why did you make an adaptor rather than a new shank complete, are there some features on the business end that would be hard to reproduce?
It is only just nipped . Some of the dies are a few thou too wide & the head will bind up , depends on the manufacturer . I need to grind a fraction off some of them . Cheers 👍
G'day Max, I see you parting "upside down" to how I do. Could you please talk about the why's and advantages or limitations. Thanks, Butch. ps, That stock is quality reusium grade 0.0 Also what make of file do you use? good ones seem hard to find these days. thanks
I use single cut files for the lathe & general work . I run the parting blade upside down as it gives next to no issues compared to the other way like chatter & dig in issues . You can safely feed in in a lot harder also , as you have to do when parting induction hardened chrome bar . 👍
Max, I was just thinking about the die heads. I have a Geometric copy 5/16” DSA and a 9/16” Geometric DSA made for Hardinge. Man, useful chasers are so hard to get, while the useless ones are all over. The reason for my post is that I always have used these as a push off. Watching you use the Coventry as a pull off made me think about that, as it’s simpler. But I just tried that in my hand and those springs are so strong I don’t see how they can be used with anything under maybe 5/16” without damaging the threads. Are the Coventry springs that strong? Also I’ve never trusted the idea of using the tailstock as a slide as the mass is high for small threads, so I made a sleeve that allows the die to slide forwards without rotating.
Check to make sure your springs are not over adjusted . 8mm is the smallest with this size head otherwise the thread can not handle the spring release pressure . They make another variation with a different release mechanism for small threads .👍
@@swanvalleymachineshop I hadn’t looked at the manual for a pretty long time. I remember that I only use them as a push off because of the spring. So I just looked at it and there’s no way to adjust the spring tension in the manual. Now that I just read it, I see why I never tried. The 9/16th head is so tensioned that holding it in my hands, I can’t push it off. It moves, but it’s too much to release it. The 5/16th isn’t nearly as tight, but seems too tight for small screws.
@@melgross The 2 small screws behind the front plate . They can be backed out as long as their is still enough threads to retain the spring pressure . Wound too far in & the die will not release .
Hey MAX. I wanted to send you some of those spiral wound sanding rolls that I mentioned in your last video. I found them on McMaster-Carr, and I know that they do not service the Australian continent, so I figured I would send you some to try, but I am unaware of how to find your postal address. If you could let me know where to send them, I'll send them to you, a long with the small arbor shank required to use them. I feel quite sure you will love them. If you want me to email you I can do that, but I currently do not have your email address, but I think I've heard you say what it is before, not sure though. Let me know, and I'll be in touch, Eric Patterson from Phoenix, Arizona USA
Inches and Deg F ! The tapers for the arbor are a no brainer with Tangent Engineering's compound slide sine bar . Saves all the dicking around adjusting . Cheers 👍
@@swanvalleymachineshop hmm. I’ll have to look into that. Well, if a degree F is a banana, then a degree C is about 1 5/8 bananas. That’s a clumsy measurement system.
Great Video, Used geometic heads alot back in the 1970's and 80's. You are lucky to have all the cutting dies for those heads. I love the camera shots, and the closeups were for real. But the Slow-Mo shots. WOW. I need to work on that technique. Your videos are always special, But this one Really Stood Out. Thanks for shareing.
Max, you're too modest. I ALWAYS get something out of your videos! Trouble is, I'm an old fart who wishes he'd done this stuff years ago. Regards from Townsville, Col.
😮😮Morning Max, I wish I could send you some rain - we have too much of it here in Scotland ! A quick question, Can those Coventry Die Heads roll threads as well as cut them, just curious ?? Cheers, Bob.
No , thread rolling is done a different tool /machine . We could do with some of your rain though . I know that when it does finally come , i will be whinging because it's always raining ! Cheers 👍
You are very good at what you do! Please do not show speeded up video's, just edit out if needed. If you want to watch a fast Jack Ass, poke a hot soldering up his yahoo and whistle Dixie.
Hey Max, another great video. I need to do the same for my 3/4" Die Head. I need to get the Capstan up and running as well in amongst everything else. Cheers.
i detest those brazed pos things. every time i try to use one it goes right into the bin within minutes. I tossed a whole pile of new carbaloys because they would run a few inches and then spit chips. HSS or inserts.

Well, over here some parts of the country are flooded. Talking about rain...
And it looks like it's not the first time you make a tapered adaptor :)

I use single cut files for the lathe & general work . I run the parting blade upside down as it gives next to no issues compared to the other way like chatter & dig in issues . You can safely feed in in a lot harder also , as you have to do when parting induction hardened chrome bar . 👍
Max, I was just thinking about the die heads. I have a Geometric copy 5/16” DSA and a 9/16” Geometric DSA made for Hardinge. Man, useful chasers are so hard to get, while the useless ones are all over. The reason for my post is that I always have used these as a push off. Watching you use the Coventry as a pull off made me think about that, as it’s simpler. But I just tried that in my hand and those springs are so strong I don’t see how they can be used with anything under maybe 5/16” without damaging the threads. Are the Coventry springs that strong? Also I’ve never trusted the idea of using the tailstock as a slide as the mass is high for small threads, so I made a sleeve that allows the die to slide forwards without rotating.
Check to make sure your springs are not over adjusted . 8mm is the smallest with this size head otherwise the thread can not handle the spring release pressure . They make another variation with a different release mechanism for small threads .👍
@@swanvalleymachineshop I hadn’t looked at the manual for a pretty long time. I remember that I only use them as a push off because of the spring. So I just looked at it and there’s no way to adjust the spring tension in the manual. Now that I just read it, I see why I never tried. The 9/16th head is so tensioned that holding it in my hands, I can’t push it off. It moves, but it’s too much to release it. The 5/16th isn’t nearly as tight, but seems too tight for small screws.
@@melgross The 2 small screws behind the front plate . They can be backed out as long as their is still enough threads to retain the spring pressure . Wound too far in & the die will not release .
@@swanvalleymachineshop thanks. I’ll check that. Still don’t know why the manual doesn’t mention that.
where did you buy the anchor lube from
Had it for years , someone bought it back with them from USA . 👍
Hey MAX. I wanted to send you some of those spiral wound sanding rolls that I mentioned in your last video. I found them on McMaster-Carr, and I know that they do not service the Australian continent, so I figured I would send you some to try, but I am unaware of how to find your postal address. If you could let me know where to send them, I'll send them to you, a long with the small arbor shank required to use them. I feel quite sure you will love them. If you want me to email you I can do that, but I currently do not have your email address, but I think I've heard you say what it is before, not sure though. Let me know, and I'll be in touch, Eric Patterson from Phoenix, Arizona USA
Hey thanks . theswanvalleymachineshop@gmail.com is my email . Cheers 👍
Hello,how did you cut the taper?right on fistgo
With the compound slide . 👍
👍
Cheers 👍
How do you de-burr the inside of a round part like that ?
I use a fine curved needle file . 👍
You sure that's not Rustonium?
It could be ! 👍
First rate...
Thanks Dave . 👍
Max what’s going to stop the morse taper pulling out when the Coventry comes, to the stop?
It takes way more force to pull out a correctly fitting Morse taper than what the die head requires to release . 👍
Definitely not MS 😂😂
Scraptonium !
Hey, I thought bananas were inches, not degrees. What gives? By the way, that arbor was way too easy.
Inches and Deg F ! The tapers for the arbor are a no brainer with Tangent Engineering's compound slide sine bar . Saves all the dicking around adjusting . Cheers 👍
@@swanvalleymachineshop hmm. I’ll have to look into that. Well, if a degree F is a banana, then a degree C is about 1 5/8 bananas. That’s a clumsy measurement system.
Thanks Max, great learning session.
No worries 👍
Great Video, Used geometic heads alot back in the 1970's and 80's. You are lucky to have all the cutting dies for those heads. I love the camera shots, and the closeups were for real. But the Slow-Mo shots. WOW. I need to work on that technique. Your videos are always special, But this one Really Stood Out. Thanks for shareing.
Thanks 👍
Max, you're too modest. I ALWAYS get something out of your videos! Trouble is, I'm an old fart who wishes he'd done this stuff years ago. Regards from Townsville, Col.
Thanks 👍
😮😮Morning Max, I wish I could send you some rain - we have too much of it here in Scotland !
A quick question, Can those Coventry Die Heads roll threads as well as cut them, just curious ?? Cheers, Bob.
No , thread rolling is done a different tool /machine . We could do with some of your rain though . I know that when it does finally come , i will be whinging because it's always raining ! Cheers 👍
You are very good at what you do!
Please do not show speeded up video's, just edit out if needed.
If you want to watch a fast Jack Ass, poke a hot soldering up his yahoo and whistle Dixie.
Thanks . It is done to save time & so you still see roughly what is going on , other than l load of disjointed clips . 👍
Hey Max, another great video. I need to do the same for my 3/4" Die Head. I need to get the Capstan up and running as well in amongst everything else. Cheers.
Lol , i have that issue as well . Need to get the Capstan sorted ! 👍
i detest those brazed pos things. every time i try to use one it goes right into the bin within minutes. I tossed a whole pile of new carbaloys because they would run a few inches and then spit chips. HSS or inserts.
Try the Micro 100's . I only ever use brazed carbides for finish work & form tools . 👍
thats a nice way for threading max.
cheers
ben
No worries 👍
