This tutorial is not about turning pens, but how to make your own thorn kit.
These pictures show the final assembly and together with a penline button (Streamline Pen). There are many types and styles of kits available on eBay and elsewhere.
I could have bought a basic kit including a clamping sleeve with a morning tapered No. 2 shaft (woodworking lathe) for about Aus $ 30. I would need a tapered tapered # 3 for my black handle and I already have 3 and 4 jaw chucks for my lathe that will be used to secure and spin the mandrel. You can also buy different sizes of bushings to suit the type of pen made. I have chosen to make FREE bushings of old bolts etc.
The mandrel also needs a lock nut to tighten the assembled kit to face the headstock chuck (to keep pen blanks secure while turning them down to size). [1
The components needed are:
1x 6mm round bar – it must be perfectly straight. I used a bar from an old discarded Canon inkjet printer.
1x 12mm x 80mm or longer steel bolt – I saved mine from something thrown out a year or two ago
1x 25mm round steel bar – Fetched a 300mm at a local metal industry as scrap – they gave me some sizes.
