  1. Hello Sir, Don't know about that Phil, She's coming together slowly. We were worried about sandblasting the gearbox, steering box and transfercase incase the sand damaged the oilseals or sand got inside any of the casings, so thats why we used the wire wheel which seems to take forever ! Hopefully all the primered parts will be olive drab by Sunday.

  2. I have just had a few days in Devon where I have seen what Father has been up to and been able to pick up the lorry once again. You may remember the piston castings we had poured. Father machined the ends and the bore and then took them to a pal who machined the gudgeon pin holes for us. He then turned up a dummy gudgeon pin and bored a block to fit it. After mounting a piece of steel on the face plate and turning a spigot to fit the piston bores, he set up a piston with the dummy gudgeon pin and used a draw-bar to pull it back onto the plate. This left it firm enough for me to turn it. Father had previously rescued the rings from the original pistons and we deem these good enough to re-use so I cut the grooves to suit. The diameter was turned in steps ranging from 4.507 at the crown to 4.515 dia at the skirt. Hopefully this time, we won't have the seizing problems that we had with the Thornycroft! A quick try in the bore just to prove a point! Almost complete and require only some radial oil holes just below the bottom rings. Time to start thinking about the rest of the engine! Steve 🙂
