Threading with a Geometric Die Head

- I thought today was as good of a day as any to make a geometric die head video, I bought this when I restored the turret late and have been using it regularly ever since.

That attachment is so cool. Glad you get your hands on one. I’ll check out more videos.❤
Thank you for sharing, I recently started using die heads as well. I also found very little information about their use online. I have found that I have the best results when I allow the turret to feed at the pitch of the chasers, It’s nerve racking, but it just works. Also, I use flooding oil, they need tons of oil to work best, it’s also very good for your machine. There are remastered company videos from Geometric that have a wealth of information on here.
I have several of these and have been threading on the turret lathe for many years. If you leave the die head open advance the turret until your desired end of thread clearance is where you want it you should be able to engage the feed lock the turret slide and tighten down the stop until the feed trips out. Now it should be set to stop exactly where you put it. Try it with using a shim for clearance and you will be able to set up the same each time first time! I love how you are able to create and market this product. Well done!
Very cool machine
Very cool, thanks!
that is cool.
Just purchased a Jones & Lamson 16S threading die head on Ebay,
Hi there, nice video, I'm in the Uk, and I use something similar but smaller than you have, but it does look like your's is a Coventry Die Head, or Alfred Herbert Die Head.(like mine) On mine there are two settings, for a rough cut and a finishing cut, so you might look and see if yours has the same facility. When first engaging with the bar stock, make sure you compress the spings in the head to ensure a good start for your thread, hope you don't mind my imput, I've been using these things for years, take care, Dave
Thanks, it’s a geometric brand as far as I know. Did you watch the whole video? particularly the part about the roughing and finishing lever? Your comment suggest you didn’t make it all the way through
Yes, I did watch all the way through, sorry I missed that bit! That's great then, gives a better finish. sounds like my die box then.👍
That is a Geometric Die Head, it looks like a DDSA type, and about 1-1/2” size. Thats a nice heavy duty die head with all the features one could have.
I know them as Herbert die heads but that was probably because that's what the company had in stock. We had ones suitable for 2BA up to 2-3" BSP, maybe bigger it is getting a bit fuzzy after 30+ years. Most of the stuff was small so the Ward 7 was far to big.
im a threading specialist from detroit and i recommend that you increase your feeds and speeds to not have the tooling engaged for so long heat is not good for the chasers shoot and scoot.
There is no feed to adjust, the chasers screw them selves onto the bar and pull the turret / geometric along with them however perhaps a higher rpm wouldn’t hurt I just simply do not know what the right rpm should be and at $100 per chaser I don’t like to experiment
love the machine @@westislespecialprojects
Thank u for the information i have a turret lathe with 2 geo heads
You lathe Must have enought torque in order to keep that much of power.
테롓(헤드)선반 ? 구입가 얼마입니까 ~!??
Is there a way to install a compound rest on a heavy turret lathe like this?
Not on mine
Great explanation! I understand that the geometric die is easier and faster, but can you also single point thread on this machine, like you would on a regular manual lathe?
No it can’t, it has a variety of feed rates but none that will match the pitch of a thread.
@@westislespecialprojects thanks for the explanation!
Sir I want to training with u
