Details about the bench top??

Oh nice! I never would have thought of grinding a die down. I do have a surface grinder.

Yea using a die in the tailstock would be easier. There are some bolts I need to replace which are custom cut. They have threads that are machined up to a shoulder. Maybe .050" short of the shoulder. My first attempt with a die to fab new ones, resulted in the threads not going far enough...

That's a great tip. I like it. Now that I think about it, there are two mandrel type parts at the shop that are very similar to what you described. They have a large o.d. though. Something like 2" and 3 or 4 inch.

1/2"-13 thread

So here is another practice run on 1/2" cold roll. I am super pleased. I am confident now to make a mandrel for some small belt rollers so they can be turned back to level.

Right on. I will give that a try tomorrow morning. I am still kind of in shock I didn't realize I was setting the compound at 60-deg. instead of 30. LoL.

Ok quick attempt and quick pictures after I was finished. One heckuva better looking thread. I didn't have a chance to mic them with the wires yet but they sure are much better. Thanx guys for helping me see the error.

I was planning to take that picture today when I get over to the lathe. Good call on that one.

Ohhhhh ****. I bet you guys are right. I'm setting the compound by the 30-deg. mark which is relating to the longitude of the machine. That makes perfect sense. Gonna go try that as soon as I get a chance. I will post my results. Daaaaaannnng it. I feel humbled and dumb now. LoL

In this picture I had just attempted feeding left to right with the insert upside down and lathe running reverse. I have attempted leaving the half nut engaged with similar poor results. The lathe is a Jet GH1660-ZX and all other operations seem to be precise and consistent. I'll look for...

I consistently get results like the attached picture. Seems I am only cutting one side of the thread. I have tried threading towards the head stock and away from it. I am using a fishtail gauge. I have tried feeding the compound at 29½ deg. and 30 deg. and tried Zero degree infeed with the cross...

So I've been using a modified Harbor Freight cabinet the past year. Added a foot pedal setup and flood lights as well. It has been perfect. But now I'm getting into parts that are up to 48" long and 18" wide. I can fabricate a new cabinet but not sure about dimensions for the lower hopper...

I am looking for the tapered nozzle and nut from the picture attached. I already own the exact gun in the picture but it came with pink, ceramic, square, nozzles. Is this a proprietary nozzle from the Tacoma Company? I always seem to come up with searches that shows the nozzle being sold with...

The widest part near the base mic's at .295 which is very near 9/32". So it's a bit smaller than 7/16". 1949 caddyman I suppose i could thread in a threaded stem and call it good so long as they don't back out. I totally forgot about McMaster Carr. I'm gonna check there right now.
