Need info on pipe threading, machine, head, etc.

I would be thinking 535 or even the 1224 Ridgid pipe theaders, both much beefier than the 300 series- and more expensive. But CNC would be a lot better, and why the thirty five dollar price range is appropriate. I always single point stainless on the lathe, and even then, 304 is not very easy to get good threads with.

I would be scared to do this, but I worked in a repair shop in the 90s and they threaded some 1" flush out pipes for a farm using this method.

One pass???

One pass???

That might work for him, it didn't for me

Actually when used with normal (aka sensible) threading infeeds chasers work very well, and even better for tapered threads! (no need to pre m/c the taper.

I remember them running those in black pipe 1"???? It seems like they had a weird looking ground & relieved center they used with it.
I'm gonna say 2 or 3 passes.

That will depend on the machine rigidity and set up.

Update:
I took them to the shop that used to do them for everyone.
Said he would do them and have them Monday.
He is going to charge me $20 an end.
His machine is a copy of a Ridgid type threader.
Real heavy duty.

Buy an old Landis rotary ,bigger the better ..........youll get it for scrap price ,and for sure the Landis HSS dies will thread 304.........if I could have got $20 an end ,Id be a millionaire ...........the boat guy next to me had a severe health problem when any kind of money was mentioned.
