3.1/2" LBSC Juliet locomotive
« on: July 26, 2019, 05:55:01 pm »
Hello,

Thought I'd share with you all a project that I picked up, (one of many but I'll get to them in good time).
[ Guests cannot view attachments ]

It's a 3.1/2" Juliet locomotive built to a write up and design by LBSC or Curly Lawrence to give him his other name.

The loco is in a poor state, either a badly assembled, unfinished project, or disassembled because of a problem then the rest of the bits lost. It missing a lubricator, smokebox, grate and ashpan, cab, hand pump, and a buffer. As well as quite a few nuts and bolts.

As the paintwork was, well....on metal, it was decided to strip it down for paint and tart up before finishing the remaining components. The boiler needed stripping down for an initial hydraulic anyway. So the cladding and fittings removed it seems like it's not too bad, but the hydraulic will be the test once blanking plugs are made.

The chassis is pretty bad, the eccentrics straps are loose, the lifting arms have the most play and on one side the lifting arm can be taken off without any disassembly. The piston rod guides were loose and subsequently there is also play in those, worse so on the right side.

Once they were stripped down the the chassis, I checked the top side on a flat surface, there was excessive rock in the frames, (2-3mm) on a flat surface, so unfortunately this meant further dismantling, to make sure there was a solid register surface to work to, which would enable the squaring up of the frames once ready. While I was at stripping it, I also filed the raised rivet heads around the hornblocks on the chassis, this means they can't interfere with the wheels and run, so these were filed flat. Also the derailing forks leading and training the wheels had the raised heads of the rivets filed off so they could be accurately drilled and removed to check the lower edge for a register

Worringly considering frames should be made as a parralel set the holes for the smokebox don't seem to have been drilled at the same time, and are out of alignment. Hopefully this is the only one that is out of alignment.

Wow! A lot of work required there, but it'll be worth it.

I was lucky. I acquired a similar loco (Martin Evans' Rob Roy) from an estate.

 It had been sitting on a shelf for about 25 years, but was virtually unused and required only freeing of the regulator, a thorough cleaning and lubrication, and a boiler test (successful!) before I was able to run it.

Keep working at yours!

Looking forward to the next update.

Good luck!
