You must forgive me for rushing this blog. I do feel rather pleased to have made a start on the Trevithick Dredger Engine.
The first part for the TDE was waterjet cut from 6mm mild steel. I emailed the DXF drawing Tues, it was cut out Wed and picked up today. Impressive service from Colin and Sandy at Waterjet Geelong. 340mm diameter. The finish of the cut is so good that some light filing and rounding the sharp edges is all that will be required. I will machine the bore hole after the shaft is made. The magazine article is my workshop copy. It will not remain this pristine for long.
The thinness of the flywheel is a Trevithick characteristic.
