What alloy? 6063 or 6061? The latter is harder and threads easier. If any of the pipe needs to be bent then it would have to be 6063 which is going to be softer and, in the case of machining or threading, gummier. To hand thread you generally need a good chamfer on the pipe to get the thread started.

Are the dies adjustable? And if so, are they adjusted properly? If they're too tight they can be a bitch to start. Try opening them up just a bit, get the thread started then adjust the dies down tighter. You're going to need a female thread of some sort to test the thread with anyway...

A bit old school for the pros but whatever floats your boat. A9 (in the green can) is the best lube for threading aluminum. Lube won't help with getting the thread started, though...

Relton is shitty snake oil, so catch up with the times.

I was recommending thing I know Jason has around the house.

Chlorinated paraffin would be the best option for him, but none
of the snake oil threading compounds use it anymore.

It's 6061. I'll try carefully grinding a chamfer. The dies are not adjustable. I have an old NYE threader.

How about some Irish Spring? Works great for keeping my abrasives from clogging up.

I hope to god some day I can thread some alum pipe and use sour cream. Of course I’ll swap the container to some non descript item. Two brushes, one for the pipe and the other for me to casually take a lick of when some one walks by.

Just finished a 4 month job running ally conduit from 3/4" up to 4", brand new sharp dies and kerosene or wd40 for lude, will work wonders.



Have never tried sour cream , but will on the next job.

I have threaded aluminum pipe as well, make sure your dies are sharp, or it will be a bad day. I have a die that will cut steel with no issues, but will just eat the first two or three threads off as soon as you cut them.

Be patient. Run them on and off, cleaning your cuttings more often than you think necessary.
I have had reasonable success using the kleen Flo version of WD40 and a paste lube that I believe is mostly paraffin.
