Making the Turbine Wheel for the Kamps Jet Engine

This is how I made the turbine wheel for my model jet engine based on the method in Thomas Kamps' book.
Some of the video was taken when I made the original wheel, and some was taken afterwards, using a scrapped turbine wheel blank to demonstrate the techniques I used. Both the turbine used in the engine and the scrapped blank are made from 'Hastelloy X'; a high temperature nickel alloy.

There are a lot more photos and information about the rest of the build on my website: https://misterg.org.uk/turbine-html/

Apologies for the slightly ropey audio in a couple of places.
