Thanks Paul. It was my old mate “machining tips and tricks with Peter Pilbeam” (an expat fellow English man) who explained to me how to do it. I was going to make a Morse tapered arbor 🤦♂️
G’day Matty. Nearly as good as something you would make buddy. Someday soon I’ll be as good as you and Max mate 😉. Jokes aside, the sleeve fits like a finger in a backside, bloody hard to line up at times and it gets stuck. Cheers Matty 🍻
Hi Craig, hope you’re doing well buddy. Thanks for watching. This was an excellent idea, but I can’t take the credit for it as that belongs to my old buddy Peter Pilbeam. I look forward to using the die heads. Cheers 🍻
Nice project! I have never considered making a sleeve attachment for the tailstock. My tap follower has a reversible spring loaded pin with one side having a point and the other having a cone cut in the end for taps that have a pyramidal point on the back end.
Definitely a worthy project to make. I’m excited to use these Coventry die heads. Your tap follower sounds better than mine. Mine only has the point, but is spring-loaded 👍🍻
Fantastic job Aaron. The outside tailstock attachment idea was totally new to me opens up lots of possibilities. Thank you for the ammunition for thought
Thanks Chris. Yes the positive pressure pump sprayer is the only way to go. I was sick and tired of the pump type blocking up and or stop working all the time. Cheers 🍻
Nice one Aaron. I've contemplated using the outside of the tailstock barrel to mount accessories on. Glad to see it done, great job it works well. Tony
Thanks Tony. My old mate Peter Pilbeam gave me inspiration for doing it this way. It’s was a excellent idea, as I was going to make a MT3 arbor to hold it. Thanks for watching 👍🍻
@@AaronEngineering That's a much better way using the full rigidity of the tailstock barrel compared to the reduced Morse taper arbor diameter to support all that extra weight and overhang. Tony
Nice! I might have to copy that. I've got a turret to go on my Colchester Triumph but it's a pita to fit & it would be good to be able to use a Coventry die head on the tailstock instead.
Absolutely, I strongly recommend it. Wish I could claim credit for the idea, but it was my old buddy Peter Pilbeam who provided a solution. Cheers 🍻 Aaron
G’day Peter hope you’re well. Thanks for popping by to check out my video. No fancy machining here on this product, but I can’t wait to start using these things. That’s an excellent idea and I will cover that in an upcoming video. Thanks for the idea mate. Cheers 👍🍻
Funny. I just made those adapters for my lathe. But what I did was to remove the tailstock quill and make another one that I drilled out all the way. It’s 2” longer than the real quill. The reason I did that was to not have the tailstock pulling for the thread. This way the quill pulls straight out from the tailstock. It has much less mass so that I don’t have to push the tailstock when threading. I have mostly Geometric heads which also have the push off lever. I prefer those so the spring doesn’t have to pull the head at the end. For large screws it doesn’t really matter, but when doing small screws with the small heads I don’t like the tension produced. It can’t be good for the thread. For the pull off models such as the Rubometric 1”, I made a finger on the bottom of the adapter, that goes over the quill I made. This contacts the carriage, the way the tailstock would. I have three adapters that go on that quill for different diameter shafts for the different size heads. As you know, it was a bit of work, having to make a 1.0625” hole all the way through an 11” shaft made of 1144. But that lets me make a long thread.
Hi Mel. Thanks for watching and commenting. Your idea sounds really cool. I was too lazy and just made a simple adapter. This way I could put the coventry die heads to work immediately to make those BSW bolts for my friends vintage engine. Your ones sound like an excellent idea. Thanks again. Regards, Aaron.
Thanks Max. I imagine you would have used many of these before. You probably got some coventry die heads too. Hopefully I’ll get some cutting threads soon. Cheers mate 👍🍻
I've got one of these along with a load of metric die sets but haven't got round to making up an adaptor yet. I'd planned to make an MT3 adaptor but your idea is much better, attaching to the tailstock barrel. I will need to check my key is strong enough to withstand the torque. You may have given me the impetus to finish it off but on the other hand I could do without the distraction....
G’day Murray. I highly recommend making one mate. My old mate Peter Pilbeam suggested that I do it this way. This is how he runs his die head on his big Japanese lathe. Cheers 🍻
Thanks Jim. I was doing voice over on the fly, and made a few mistakes. Thanks for the correction. I drum this in the students all the time 1” = 25.4mm 👍🍻
Good job, Aaron. Dont worry so much about the surface finish. A little emery cloth will fix that. In most cases its the steel itself that is crap, not our tools or cutting tecnique. i´ve had steel that made noises where i thought it will rip my carbide cutter in half. It came from an unknown planet and was sold as mild steel. On the other hand i bought a load of german made steel from Krupp that cut supersmooth like butter. It´s obviously more dependent on the manufacturer than on our machining/toolmaking art.
Thanks music man. Yeah, hard to tell when you don’t the type of steel. Especially since it was scrap metal lying out in the weather. I’d love some of that German steel you had. Cheers 🍻 Aaron
Hey Anthony. Yes mate it’s the way to do it. Me old mate Peter Pilbeam parted his wisdom on me. I was going to make an MT3 arbor. This way is much easier. Cheers 🍻
Hi Az…. Very educational mate ! I’ve got a (second hand) small die head lined up, so your vid is timely. Those things are like rocking horse shit mate, and die chasers for them are like Unicorn poo 🤣🤣🤣 Your fortunate to have a mate who has a couple 👍 Robert PS I’d love to get a turret or capstan adaption for the 960B 🙏
G’day Robert. Yes you’re not wrong mate, they are definitely hard to come by these days. Wayne has 3 sizes with a lot of chasers. Can’t wait to give them a try. I have to make some studs for him. Cheers 🍻
Nice job Aaron. You might consider leaving that die holder loose rather than locking it the tail stock spindle. That way you can feel when it grabs and let it go to spin freely rather than breaking something. Some dies work better than others but in my experience the large ones can be difficult to start and tend to grab when you least expect it.
Hi Steven. Great advice mate. I’ll keep that in mind when using it. My old Colchester sometimes stalls when loading her up too much, but it has got more torque in the lower RPM range, and that’s where you tap and screw cut. I’ll keep an eye on it. Cheers👍🍻
Ha ha ha, yeah I’m not sure if you guys use that turn over there. Paddock is a English (Pommy) term that means the same as field, or backyard. Cheers mate 👍🍻
Hi Aaron, nice machine work, & the adapter has nice tolerances both sides. With the bolts on the tailstock, won't they mark the groove slot you mentioned ??? Would it be better with a brass or bronze tip on the bolts ?.
Hi Ted. I used it on the weekend and it worked a treat. There is now marking or scoring at the moment, but your idea would be a much better one. Cheers, Aaron.
Nice little improvement for your lathe Mate. When you need to do multiple threads now you won't believe how quick Die Heads are. Are they Alfred Herbert branded heads?
Thanks Micheal. No idea on the brand, but next time I’m in the workshop I’ll have a good look over to see. I can’t wait to start using these things. I’ve got a heap of studs to make for Wayne, so I’ll put on the Bison 5C collet chuck to make them. Cheers mate, and talk on the phone soon. 👍🍻
These die heads, Coventry, Namco, Landmatic, Wagner are more commonly used on automatic lathes for repetition work owing to the time and attempts to set up. I don't think they would be suitable for a centre lathe.
Hi Andy. Yes you are correct. They were commonly used on manual turret and automatic lathes. However, they do work exceptionally well in the tail stock, but you must allow it to slide. Others have mounted smaller die heads to the tool post. I’ve made many BSW Whitworth bolts & studs via this configuration. Much faster than screw cutting… Thank you for watching and commenting. Cheers Aaron 🍻
Just saw Mr Crispin make one of these for his myford. You guys call this a Coventry Head. That is a new term to me. We call these Geometric Die Heads. Just to keep things clear….. This thing does not accept standard dies.
Aaron in answer to your question about taps that have a point on the rear instead of a centre hole, I saw this just the other day ua-cam.com/video/UnMnrf_bIO4/v-deo.html starting at 12:05 If you already have a tap follower, you may already have the tool you want.

Five inches is 127 mm exactly, and that is occasionally noteworthy because 125:127 is a useful integer ratio between the two systems.
