Scrap Tank Test Build 8 – Casting Masters

The update on the Scrap Tank test build shows it looking like this:

Tank 1

The eagle eyed, and indeed the slightly less than eagle eyed, amongst you will notice that this is not a whole lot different to the last update, just a few fittings have been installed – basically the ones I could glean off other things; the safety valves/bonnet and smoke box from Lochgorm Models and the clack valves from Alan Gibson (but much cut down as they are really much too big).  I have not been able to fit any other castings because they don’t exist, so I have had to do some more work on these.

So it is back to the CAD machine to draw up a series of 3D masters; in the top view some piston rods/part of the cross head, rear sand boxes, clack valves (now the right size which is much much smaller) and some lubricator valves.  The bottom view has some tank filler lids, front sandboxes and piston ends.

These have been printed for me by Alan Butler of Modulu who is a new entrant in the field of 3D printing and has a system/machine that can do really small parts very well indeed; definitely better than Shapeways.  Alan is a railway modeller here and blogs here – well worth a look I suggest and if you are thinking of having some things printed then I would get in touch with him.

I did not get Alan to print the dome and the chimney, partly because I had my doubts that the print would do the fine lip of the metal where it meets the boiler but mostly because I just could not work out how to draw the damn thing!  Instead, therefore I commission Jeremy Suter to make these for me:

Chimney 2

……..and very fine the look too!

So, these are the masters all sorted and they will shortly be sent of for casting.  I will be using lost wax again, as I much prefer this to white metal; although I do accept that the better white metal casters do do a grand job.
