A start on a Windsor stool

Something completely new for me but I need a shop stool and the challenge is maybe why  I am doing this - apart from learning some new skills in a totally different (for me) kind of wood turning.

Here's what I have done so far. The blank was glued up out of 3 pieces of reclaimed Teak which is different to what would normally be used but I had the wood. The turning has been done and the holes for the legs drilled. This required to make a jig to help keeping the seat at a specific angle at the drill press.

A very basic jig knocked up to allow me to drill the holes in the seat. While the holes are pre-drilled a characteristic of the Windsor is that the holes are tapered to log the legs in place.
This led me to making the next jig.....

Here's my tapered reamer in process - I don't know how well this will work but I should be able report back next week. Final fitting and sharpening of the blade is required.
