Pen blanks
tinkerer:
Ok, now I am confused :scratch: No way you would use a chaser on metal, :bugeye: we are talking about chasing on plastic and wood, right?
raynerd:
Sorry - yes acrylic pen blanks!
But - I have no idea if a chaser can be used on metal?
bogstandard:
Chasers can be used on metal, but a slightly different type.
Just searching for 'Thread chasers' should automatically bring up both types, hand and machine.

What you would tend to do for metal is just hold one of the dies in your toolpost and use that.

tinkerer:
I was able to get in the shop again today. After parting the blanks I center drilled with 7mm and superglued the sleeves in. I didn't take a picture of the drilling.
I then mounted one blank at a time and shaped them. My only problem was the taper from the nib. I have to hand turn the compound and couldn't get the same finish the auto feed affords. I guess that takes practice. If there is a better way to get the taper done, please let me know.
I still have to put the accent ring in. I did one in yellow acrylic, but decided to change that to red. That should not be a challenge.
For the taper, I set the compound at about 4 deg.
The gap between the barrels is where the acrylic ring will go.
When I am satisfied with it, I will disassemble and polish. I checked into powder coating today and the guy was in meetings all day. Hopefully he will call tomorrow and I will find out if it is cost prohibitive.

Smart job mate!
