Hunslet Quarry Tank- Work starts

Hi, I thought it was time to report what is happening in the Wrightscale workshop.  After designing a tool for the laser cutter to work from and taking the prototype to bits to measure all the component to be etched I have finally reached the start of the first batch to be built. The metal is in stock, the castings likewise, and the first batch of laser cut parts and the etch arrived last week.
The first sheet of laser cutting, the loco sides frames, are in the workshop for assembly.  The water tank has been assembled to test the design. Soon there should be an assembled chassis.
I think I am going to overlay the steel frames with etched overlays with the axlebox, rivet and bolt detail etched, rather than assemble the frames using actual scale bolts etc.  It is hard to believe but a single 3/64" brass rivet is now 6p, so I think soldering in 32 per loco pair of frames is a bit over the top.  I have made provision for riveted  running plates and also the water tank can be riveted too.
So now it is test assemble the frames, machine a batch of axleboxes, slip eccentric components, wheels, cranks, crankpins, cylinder covers, valve chests, valves, pistons......... and the chassis can be completed and air tested.
Soon be will be writing to the first few on the interest list to offer them an engine.  Hopefully this batch will be completed later this year. So watch the blog and follow the progress.
Sarah's book- Colonel Péchot: Tracks to the Trenches is getting near the end; she is doing the final proof reading.  So if you want a copy of the authorative book on the innovation of narrow gauge military transport with loads of good photos, lots of drawings, maps and 22 years of research watch out for her postings over the next couple of months.

  1. Nice to see the photo of the work in progress. I have long yearned for a 16mm Quarry Hunslet and finding the opportunity to have one at a sensible price was one of the highlights of the year!
