Coming along nicely Tim :thumbup:

Just a reminder that the cutouts on the side of the top plate are not optional, as you need clearance for the steam chests. The cutouts in the front and back are optional.

Thanks for that Kvom, I hadn't realised that. :thumbup: That will be next on the list to do then.

On mine the flange of the steam chest packing gland is a little bit wider than the width of the steam chest, so I had to cut the sides a tad deaper than the edge of the block.

spuddevans:
Got a bit more done today, I started by milling out a recess on the mounting plate for the steam chests.

Then I drilled and tapped the cylinder block using a newly aquired tapping stand, I totally reccomend everyone either make or buy one, makes tapping so much easier :thumbup:

I only drilled and tapped the bottom of the block as I've decided to remake the top-caps as I messed up the holes on them.

I then did a little assembly. After a little polishing on one piston, ( on the rod not the actual piston, as the rod was slightly oversize ( about 0.04mm ) and would not go through the packing gland ) I was able to assemble the pistons and packing glands into the cylinder, and then attach the mounting plate.

Then I assembled the crossheads and rods, and after a little fiddling and messing around, widening one set of crosshead-rod-holes a little, and ...... It slides in and out !!! (ok a little stiff, but it still works)

So next I'll be working on making 2 new top-caps, then it'll be on to the bearing blocks.
