As we are all locked indoors and it does create a strange world.
An NSWGR modeller approached me with a request if it would be possible to add smoke and maybe cylinder cocks to NSWGR small locomotives. Now, this had all been looked at by myself, but there were always a number of reservations on my part, with the main one being the use of oil. A mussed-up fill could result in a real mess as would a serious derailment. The other issue was the reported build-up of oil from a lot of use in a layout environment.
After noting my objections I was directed to a Facebook page of a UK engine using water so the question was how with the most obvious answer a small ultrasonic generator, my curiosity was pricked.
So after a few days of research, I obtained a sample to destroy and then decided to see if it could be possible to have stack and cylinder cocks. with the hardware that is required to be installed.
The renders below show the current results.
The smokebox is a Model O - 50 Class and it would all seem to fit, so all the parts were sourced and the next step will be undertaken once I have enough parts and a new printer. The parts will have to be a combination of FDM and resin depending on size. The larger parts at this time will be FDM ABS to allow them to be glued into a solid assembly.
This will be feed from a tank in the tender this is where one of the issues arises but in principle, it looks like a 50/50 chance but the use of water is appealing.
