Hi All more progress pix of the tender build getting there slowly , still cant see the light at the end of the tunnel
Re: Victorian R-CLASS 4-6-4
Thanks Gary for the info. I had it pointed out from an other member of this forum that solid wheels were used on the SG conversion R. The tender is coming along nicely. Keep up the great work.VK2DJ wrote:Hi Luke the R as far as I know they never used solid wheels at all they were all 10 spoke

G'day All finally received the scale brake blocks for the tender, the 3D modelling was done by Philip Monsbourgh in the Netherlands ,the casting was done by Michael Jack in New Zealand, very pleased with the results they add realism to bogies

Re: Victorian R-CLASS 4-6-4
Hello Garry,
when I scrolled all your impressive photos, there was the information regarding working preasure of your vessel (90 psi).
My type of oil burner should get a nozel of 0.6 mm to 0.7 mm diameter (steam).
A nozel of 1.6 mm diameter should be used for the fuel then. (The drawing is showing these dimensions, too).
These dimensions will atomize about 4 liters of diesel per h @ 90 psi with an adequate amount of steam.
The steam nozel should be tapered slightly (Laval). The adjustable outer nozel must get a precise fit not to suck air instead of fuel.
The adjust may be done either by a lever (as shown) or a gear (for more precision). The angle to be turned from 'shut' to 'full' will be less than 90° @ thread of 1 mm / turn.

Progress on the build has been interrupted by a 5 week holiday to the UK to visit the Harrogate Model Engineering Exhibition then some home renovations,
The tender under frame is finished started the detail on the tank then realised I still have approx.6 months to finish so I decided to have a change & finish the boiler
