Just purchased a headspinner from Jantz, can anyone tell me what speed they are best used at, if lubricant is needed and what materials they can and can’t be used on?
Many thanks.
 
I haven’t used the jantz. I’ve used a single flute cup burr which is likely similar

I just use it in a cordless hand drill and low speed and works well on brass, nickel silver pins etc.

I wouldn’t overthink it. You will be using it on soft pin material presumably

grab a couple pins and try it
 
Well I hope you have better luck with it than I did. I just bought one to finish NS pins on a deer handle scales. It didn't do anything but slightly round off the corners of the pins. I made a clamp to hold the knife and used my floor drill press. Let us know if it works for you.

Thats all it’s doing for me, hence the reason me asking, thought I was doing something wrong!
 
If your doing something wrong we are both doing it wrong. Most disappointing thing I've bought from Jantz. I had high hopes. My only thought one is suppose to peen the head and use it to clean it up but after using it on a square cut NS pin I can't imagine how well it would clean up a already peened pin. But I never tried that.
 
I can't tell exactly which Jantz product you got.
I bought a set of 12 carbide cup burrs from Rio Grande for $30. They cover a range of sizes and what you are describing sounds like what happens when I use too big of a size.
In the end I also drilled various sized holes in a steel block and use it to peen one end before doing the other side once on the work piece.
 
As Bill said, it takes a good bit of down pressure to "form" the NS or brass head. They won't work on steel. They are burnishers more than cutters. I think they are designed more to smooth the edges than to make a perfect dome.
That said, I now use a cup burr for this task.
 
I've seen a couple of makers using "dome spinners" on brass pin by relying on friction to hot form the dome. No lube, just heat from the friction and pressure from the drill press. The potential problem with this is that you can burn the surrounding material if you're not careful.

If you're trying to dome pins with the Jantz spinner, I'd probably get it 90% there with a ball peen or a nail set and then finish it up with the spinner for uniformity. Like Stacy said, they're really more for burnishing or polishing.

FWIW, Nick Wheeler had a pretty good vid on doming pins for his bowies a while back.
 
i guess me thinking a Peened pin is more like a Rivet with a bigger rounded head was Wrong !!
i used to do them by placing a pin into a true hole (Fixture) and peen the head until it was close to correct head size
then remove from (Fixture) round head and install allowing enough pin to protrude to make a equal head..
then spin to round with a cup burr.. the fresh head /and clean up the other side in case it deformed at all...
 
I use concave punches for many of my pins. They are polished smooth in various sizes.
Most of my raised pin heads are simply buffed smooth after peening.
In rare instances, I use cup burrs.
Spinners are not generally necessary, unless you are trying to replicate factory-spun pins.
