Index wheel for Rose Engine

I recently purchased an index wheel for my lathe and my Rose Engine from Simon Hope. I bought just the index wheel rather than the complete kit.

I mounted it on the rose engine and then had to design and make an adjustable arm and locking pin for the index wheel. I made the arm out of plastic on my 3D printer just to prove the concept before milling it out of aluminium. The locking pin I turned on my metal lathe and again used a 3D printed knurled knob to retain it, this will be replaced by a brass one in due course.

I also made a small fly cutter to mount in my drilling frame turned from an off cut of steel with one fixed location for a CNC milling cutter which is retained by a grub screw. (The angle of the photo makes it look like the cutter is not parallel to the centre shaft).

This is the result of my first attempt on a piece of scrap Olive wood (one circle is off due to an error in initial setup of the drilling frame).
