H&G die head help please

[sundown57]

I've studied this thing all day. i didn't do well buying it. I have tons of chasers all different pitch but no jaws to hold them in. and no one has chasers for the J&L head i bought

 

[benmychree]

What size/type J&L die head? they made tangent die heads and the J&L Hartness radial chaser die head, an older design. I have two J&L tangent die heads with all the chasers and sharpening and setting jigs, they are big ones with 2 1/2" shanks and 1 1/2 & 2" capacity, I bought them with a turret lathe, a #5 Warner & Swasey that I later sold at a profit without its pneumatic bar feeder that I kept to use on my #4 W&S..

By far, the most convenient die head to set up and use and plentiful sources of chasers is the Geometric Die Head, either the original or clones, due to their design and simplicity, and easy adjustability for fit of thread and relative ease to sharpen the chasers.

the J&L is a model 20S.

I’m waiting on a reply from them myself but I came across some old threads that said they have digital copies of an H&G manual

I believe the carriers have the rod size ranges engraved on them? They are strange fractions…
Different carriers for bigger/smaller stock

I came across that somewhere but am unable to find it now

I have the manual for my die heads, and I think that only one uses a second carrier set, I never really liked them because changing the carriers is a bit of a PITA, these came from the shop where I apprenticed
; these are too big for any machine that I now have, should sell them as a package deal, I use a smallish Geometric die and the Hartness die, I have a good selection of chasers for them but do more single point threading than die threading.

For production work, die heads can be real money-makers. For the hobbyist making one or two of something, it's hard to justify the cost. The price of a die head without the chasers will pay for a lot of round dies, threading tools and inserts.

i have a chance to thread 2000 1/4-20 rods. if i cant come up with a way to do it they will send them to CNC. id like to have the job

Just pulled a carrier out of my 102



Turns out mine is missing the entire trip carrier…
However, I do see two interesting allen setscrews that would otherwise be covered (red circles). Could they be adjustments maybe?

Circled in yellow is the trip mechanism to open the jaws.

they look the same as my 108. the 2 screws only move the head up and down not in and out.
