With the saddle attached, squeezing the insertion area of the post with one hand, and rotating the post by the tip of the saddle with the other hand. Took less than 30 minutes. The seatpost collar bolts were replaced with stainless steel carriage bolts from the hardware. A cheap set of vernier calipers helped with this.

This reminded me that I have a metal lathe I could finally put to good use!
