Hi,

The work needed on the parallel motion will have to wait until after the crankshaft assembly is finished.  To this end the second plastic bag has been opened.  My ideas of doing as little engineering as possible are going down the pan; quite a lot was needed on the column and beam assembly but the crankshaft bearing brackets need to be almost completely machined.  They weren’t the same height, they wobble on their bases, the securing screws screw down on to a slope and where there are threads to secured the split bearings, they are either stripped or different sizes!  So, the bearing brackets have been machined both top and bottom and the split bearing screw holes plugged along with the holes in the split bearings.  I rather suspect that there will be more holes plugged and drilled again than original when this project is finished.  The bearing brackets have been drilled and tapped and fitted to the wooden base, nothing so far has been done to the crankshaft and flywheel, it is starting to look a bit like a beam engine.
