Thread: Rob roy first build
31/05/2014 20:18:37

I would not recommend the RobRoy as a first engine. It is not a simple engine to build. I chose it in the early 90's for my first engine (Probably my last) and did "complete it" a couple years ago, sans painting. It runs well on air, however, I have had some difficulty steaming it on coal. There are some problems with the drawings, but not insurmountable. If I were to do it again, I would certainly look at the piping between the cylinders. There is very little room. Some builders have modified the piping by bringing it out in front of the cylinder chests as opposed to in between. I am now working on gas firing as per "Doubletops" recent posts. Just my thoughts. As for the boiler, I did not have any serious problems except that Martin Evans does allow soft solder for caulking the stays which I did do. I wish I hadn't. Since I am in "the states" and my club does not have such stringent testing requirements as you apparently do in Europe. I did test my boiler up to 250 psi and held it over night, so I am not too concerned about it's strength, but must be concerned about keeping the water level up in the boiler when running so as to not compromise the stays.
