Once conrods were resized the rough edges on the shafts were filed to smooth them out and reduce possible weakness in the future. They were then sanded to smooth the filing marks, bead blasted and then vapour blasted for a brand new look.
The top brass bushes then needed to be pressed in which was done with heating the con rod end with a flame and clamping down the bush to press it in. Once they were pressed in the bushes were reamed so there was a good fit with the gudgeon pins.
In the engine casing the cam shaft bushes neede to be removed , this was done by threading a large tap into them, heating the casing with a flame and drifting the bushes out.
My nephew Michael working on metal bead blasting the head which is cast iron, but someone liked the idea of it being alluminium so drenched it in some kind of silver paint. Over the years all the paint has gathered in the fins and has proved quite difficult to get out. In the end we resorted to scraping it out with a marking pick.
The engine gears were vapour blasted to get them back to new and then sprayed with some lubricant so as not to attract rust.
We also started working on getting the casings true and even on the mounting edges so as to ensure a good seal between casings. We used 80 or 100 grit sand paper roll glued to a marble base, and then sanded.
