After 30min of the vacuum, the pump was switched off, the saddle removed, and the saddle was gently dried. I used a hooded gas BBQ on the lowest setting with a accurate thermometer. I was able to hold it to a constant 50 degrees C. Over 60 degrees C will change the composition of the leather and make it very hard and can make it brittle.(Cuir Bouilli) The leather was alternated between off the mold to maximise drying, and on the mold to minimise shrinkage. After two hours in the BBQ, it was allowed to dry naturally for a few days.
When dry, I drilled the holes with an electric drill (yes it is that thick) and installed it on the frame ready for cutting.
I used bolts for this stage. I will use modified countersunk bolts for the final attachment. This will suit the shiny bits on the rest of the bike and to differentiate it from a regular Brooks.

I will post more of the trimming (inspired by Skully), and the burnishing of the edges.
