No turning on these except for polishing the brass. The two on the right are fixing to be delivered shortly. They are being traded for a used Wen dust collector.

The two pens on the right was traded off & delivered yesterday. Here is my dust collector that I traded for. It is a small dust collector that will be setting up behind my lathe.

@Sataro I think I could figure it out, but any chance of a short write-up on your process for these? I think people here in Utah would go nuts for these.

Ray-CA has posted a very good link with visuals of the steps to make the bullet pens. One step that I do different is the drill bit size. I think the 7mm drill bit size is slightly too tight since the brass casing allows no room for expansion when inserting the transmission. So I use a 9/32 drill bit. I do not solder my tubes in but use CA thick instead. I think soldering would be better. I may have to try that myself.

I just finished up another one. The 7mm hole was really tight and I had to re-drill to 9/32. Thanks Sataro for that tip!

Here is the conversion 9/32 inch to mm. I am going to start using the 9/32-inch bit now.

9/32 inch to mm - Converter Maniacs

Here is the answer with the math that shows you how to convert 9/32 inch to mm: 9 / 32 = 0.28125 0.28125 x 25.4 = 7.14375 9/32 inch = 7.14375 mm inch to mm Converter Here you can convert another fractional inch to mm. 9/33 inch to mm Here is the next fractional inch on our list that we have converted to mm.
