And Now for the Twin

A special section just for steam engines and boilers, as without these you may as well fit a sail.

Little by little!

It's easier to list what's been done than try to show everything,

With all the holes for covers plotted and drilled, they have been tapped.

The covers have had their holes opened out to clearance size.

Gland holes plotted, drilled and tapped along with the exhaust flange holes.

Studs for the glands have been made, and a load of nuts, screws, washers, and bolts have been ordered on-line.

Meanwhile I have also found up some nice material for the cross-heads and semi-finalised the design/shape. (Oh yes, and a couple of brews drunk. :lol: )

Another spell in the w'shop today, sees 300 hours broken.

Having started to the cross-head material amongst the many bits the other day, I cut the groove to full depth for the guide and brass slipper.

I then attempted to cut the piece in two with a slitting saw and gave up, far too slow. Finished it in the power hacksaw. Cleaned one end, the other end will do for a tomorrow job, getting kinda stuck 'til I get a delivery.

I love the look of freshly machined grey cast iron. It'll be a wonderful engine.

Ha ha! Yes it's one material I find it difficult NOT to get a finish on.

A little done today, not really worth the reporting, all the bolts (x12) for the Cross-head caps have been cut and fitted, and material preped for the brass slippers. Not sure I will follow through with the method yet, I have an alternative which might be easier.
