Hi all,
Got so involved in building the engine I did not do any updates in a while.
Finished the arbor, to be used later.
Elmer's horizontal mill engine.Mounted a piece of 6mm mild steel plate on the mill and machined the long sides parallel and to size. Then using a spot drill some grooves was “engraved” lengthwise.
Elmer's horizontal mill engine.The mill does not have enough cross travel to do the sides, so the work was rotated and the one end milled square. Half of it was then grooved.
Elmer's horizontal mill engine.Then rotated 180º and the last groove picked up to finish the grooving to the end. The end was then milled square and to length.

Elmer's horizontal mill engine.The plate was flipped over and all the hole drilled and counter sunk.
Elmer's horizontal mill engine.All done.
Elmer's horizontal mill engine.The base was mounted on its side.

Elmer's horizontal mill engine.The side and face cutter was used to finish the cutout for the crank and conrod. As the cutter has only a few teeth this was very slooow going.

Elmer's horizontal mill engine.With everything assembled the bearing posts was first drilled and taped for lubricators.
Elmer's horizontal mill engine.The assembly was then mounted on its side for boring the bearings.

Elmer's horizontal mill engine.Had to use one of my lathe boring bars to reach down both bearings.
Elmer's horizontal mill engine.With the bushes and a few bits added.
Elmer's horizontal mill engine.I did not like the fit of the bushes so they were remade.
Elmer's horizontal mill engine.With the help of a fixture the crank web was mounted on the mill.

Elmer's horizontal mill engine.The cutter was mounted other way around and the mill ran in reverse to get a better cut.
Elmer's horizontal mill engine.Hot off the mill.
Elmer's horizontal mill engine.After filling the end and a bit of a cleanup.
Elmer's horizontal mill engine.The end of the crankshaft was given a light knurl.
Elmer's horizontal mill engine.The crank was pressed on and tin soldered.
Elmer's horizontal mill engine.Cleaned up.
