One of the UK guys ( the turning circle ) recently introduced me to Rose Engine Turning. While doing some reading up on the subject I came across Straight Line Engine Turning and I thought this method was easiest to adapt to pen making.
Here is a prototype lathe attachment that I came up with. It's pretty basic but works ok. I did have to make a special indexing dial around the big chuck which has 5deg increments ( 72 points ) This was the most difficult part to make and I even popped a resistor in my VS controller while doing a parting cut to split it in half.
I read that the cutters need to be razor sharp and polished to work properly. I need to work on that.
The 'sparkly' bits in the cuts on the brass practice piece is actually where the brass has ripped instead of cut. But brass can be like that and it cuts clean on stainless. I just need to get the sharpening correct.
The aluminium zig-zag guide created the wavy 'moire' effect in the brass.
I'm looking forward to perfecting it as I think it would look cool on a pen.:biggrin:
