How-To:  Rifle Shell Pen Body

How-To: Rifle Shell Pen Body

I have before identified Instructables user Mrballeng as a craftsman’s craftsman, and this latest offering only serves to reinforce that opinion. His work is not flashy or complex, but it’s always thought out with exacting detail and does amazing things with everyday materials. Here, he uses a mini-lathe to bore, swage, and align two .30-06 cartridge cases before soldering them together, at the joint, and fitting the guts of a refillable plastic click-pen inside. Cool stuff.

3D-Printed Lathe

If you’d like to try your hand at turning on a lathe, but don’t want to shell out for a machine, how about printing your own EZLathe? Paul writes:

So I’ve built a complete mini lathe system I’m calling the EZLathe… Fully 3D Printable except a small motor, and a couple pieces of cheap electronics. And able to do small wood turning jobs, or small pieces of pretty much anything.

Add a few stepper motors and a controller, and before you know it you’ve got a nifty little cnc lathe.

The Turner’s Cube: Classic machinist’s exercise

The Turner’s Cube: Classic machinist’s exercise

This lovely object is more than just an interesting gewgaw: It’s called a “turner’s cube”–so named, I think, because it is a challenge for one who turns on a lathe rather than eponymously–and according to Bob Warfield, “[i]n the old days, novice machinist’s [sic] were handed one and told to work out how to make one of their own.” Bob’s got a cool page describing his efforts to make one manually and then using a CNC mill, with some bonus commentary on this thread by CNC Zone member widgitmaster, who made the cube pictured above, using the jig pictured above, on a big engine lathe. Beautiful!
