Amen to no time to die.
I have been working on my Workshop fo three years and it is not done yet, besides all of the projects
I occasionally work on instead finishing my workshop. My 12x36 lathe sat outside in a crate for the past year.
Re: Coventry die head, I'll google it but sure would like to know more.

Hi Ralph
There will be plenty of info on the internet. A bit old school these were used a lot on capstan lathes high production. With the introduction of tip tooling and CNC they are seen less and less. CNC is the way forward but these still have a place in any manual operated workshop. If you shop around you can pick them up cheap due to this reason. The chasers are still available today again shop around and can be purchased cheaply. As I mentioned they are really a production tool but if you cut one size regular well worth the investment. The size of the Coventry die head shown in the video takes upto 6mm/ ¼” die range. Hence, they are known as ¼ Coventry die head as this is the maximum size it will cut or 6mm metric ¼ UNC, UNF, BSW, BSF, and up to 2BA and all sizes below the nominal size. Hope this helps

Not cheap at all, >$100.00 for the cheapest ones on ebay.
Ralph
cant believe it just looked here (UK) and the price has shot up. Sorry for the wrong information.
The Home Engineer
Well I need to learn single point turning anyway, but for the smaller diameters it really looked interesting.
Ralph
Really a great improvement ! Nice and cleanly done, I vote for it !

I have to share this with you Ralph.
It is my 50th birthday next month and my lovely partner has put a lot of money towards a Metric Ainjest for my Colchester 1800. It is quite sad, but I am so excited, as I collect it a week today (Friday). I feel like a kid at Christmas as I am counting the days down. Now these are not cheap but they enable you to screw cut at high speed. I have cut threads at 1200rpm at work with an Ainjest.
Take a look at the video I found on youtube.

That is one super lantern chuck idea. Thanks for sharing!

I like your nice build of the lantern chuck. I understand how it works and see the benefits of having one. It would come in so handy. I am puzzled about two things though. What is the small hole in the main body end for? (unscrewing maybe?) I also noted a hex cap screw. What is it's purpose? I have done without one for way too long and I want to build for myself.
