Spent last weeks on domestick duties and finishing of a few other jobs.

Made the pistons finished the heads off on the rods griped in a collet to keep everything concentric.

Nice slide fit in the bore.

Got all the studs the same lenght by putting a couple of washers under the nut and filing the studs off flush with the nut, remove a washer and you've got them all the same amount of stud sticking out above the nut.

Made a start on the bearing housing drop a bit of a clanger when I drew it up for some reason I thought the flat bar I had put aside for this was 10mm * 55
no its 10mm * 50, never mind I see this as an oportunity to make the diference up with a bit of bling.

First job cut the three housings off the bar, blue one of them up mark it out, then stick all three in the vice and drill them all through to take two 3mm dowels to keep them lined up whilst the rest of the machining is done.

Rough drill for the bearing and the corner.

Clean the faces up to get them nice and square.

Stick a 10mm drill in the bearing hole and use this with an edge finder to get the mill on the bearing centre line.

having first marked out the holes for the bearing caps

Then drill M4 tapping

Cut the bearing caps out with a slitting saw

Tidy up the step

This is how far I've got I've stamped the caps so they will go back where they came from.
