The GTR 719 is progressing little by little. Recent work includes modifying the cylinders, sculpting and detailing the turret and adding cab roof hatches.
GTR 719 was built as a compound locomotive. I was required to remove the steam pipes out of the cylinder and replace them by square boxes made out of laminated styrene filed to size. Small steps with rounded corners were added on top of the boxes just like the prototype. Before gluing the boxes, I filed the cylinder tops flat. This way, I didn't have to adapt the boxe profile to the cylinder radius, which could have been tricky and not easy to glue. Archer anti-skid thread pattern decals will be added later on top of the steps and lubricator pipes too.
The steam turret is made of a Roundhouse sand dome from a 0-6-0T shell. I extended it with Magic Sculpt putty filed to size then glued with putty onto the boiler. When everything was dried, I drilled a small pilot hole on top and carefully using a larger drill bit by hand, I hollowed the interior.
A flat floor for the turret inside was made out of 0.5 mm styrene. Safety valves taken from a Bachmann 4-4-0 shell and one salvaged from the 2-8-0 shell where glued following the prototype.
The new cab roof got a putty job to smooth rough parts. New roof hatches are being build from styrene sheet. The hatches aren't yet glued, what you see are the side extensions that will be later filed down a little bit to the correct height.
Completing the running boards and drilling mounting holes in the boiler are among my next challenges. A tedious sand job to smooth out the surfaces before painting will be also required.
I'm really pleased to see the Bachmann stock model morphing into something completely different.
