22 September - one of the pair has sold, I
have one left (it's the one with boiler "A"). There is an oil gallery
drilled up from the bottom of the cylinder block to behind the piston valve
cavity - this has just broken through into the top face of the block (you can
just see it in photograph "n", behind the main steam inlet boss).
Another pair of part-built engines from the estate of a professional model builder, the man responsible, amongst other things, for the pair of 7 1/4 inch gauge 15xx locomotives I sold recently.
This is a pair of fine scale 5 inch gauge GWR 51xx "large Prairies" to Trevor Shortlands highly detailed design derived from works drawings, built at 1 1/6" to the foot. As with the 15xxs, these engines were being built as a pair and are both at the same stage.
There is a large amount of work done, still a considerable amount to do. Work to date (with two sets of everything listed below) comprises:
Frames erected with stretchers and horns machined and fitted
Split gunmetal axleboxes machined
Driving wheels machined and fitted to axles, complete with eccentric sheaves
Quantity of valve gear including eccentric straps, rods, expansion links
Coupling and connecting rods machined and bushed
Cylinders part-machined, liners machined
A beautifully made copper chimney (which, if it wasn't needed for the engine, would go on my desk just so I could look at it)
Set part-machined window frames
Silver soldered copper boiler
There is a large quantity of unmachined castings which appear to be much of the remainder required to complete the engine, along with two sets of drawings.
A large, powerful engine when finished - I've recently sold a complete one, there are some pictures and a video of it running in the archive here. Castings are available from Reeves.
