sorry I had to go back and read your questions I have the chilertern quad mill engine . It’s actually two twins connected together with a common flywheel . I was going to chang this but I got the flywheel to run true with the lineup rod through all the bearings so the assembly is ok for now I’ll eventually mount them on a tooling plate then the display floor. I want to be able to run various generators snd motors so the particle board is ok for now. I’m making an outer support bearing as one end of the crankshafts s longer so it overhangs some one is offered but it’s for the verticals mount quad system I have a self aligning bearing ready for mounting . This will just give added support to belt or gear drives and take load off the outer main bearing . Each main cap has a hole for an oiler so I’ll make cups for them as none that size are available. Other size I have both steam oil and machine oil in syringes I’ll add the steam displacement oiler when I’m ready for steaming . So fr it’s going together ok it’s just loaded with really small parts m2 rod cap screws m3 for most every thing else . I have two tap and drill sets for these as well as the 1/4 40 TPI ME tap . Die and drill setBore is 14 mm stroke 18 mm double acting I’m picking 1000 rpm or 2000 rpm . I’ll have an air compressor thurs evening 2 gall tank 135 psi available 2.1 cut per min at 90 psi rated.
My proposed super heater is to take boiler steam out of a dome , more stack like in appearance at this point . I can see some condensation being removed as the steam vapor is being heated the super heater will have blow off capability so the moisture can be removed . My thinking. As long as pressure and temp remain high enough there should be only dry steam as long as taken ou high enough . The super heater will be pretty heavy duty . 3/16 wall 4130 is very strong from hydraulic stand point. Most likely I’ll try to maintain about 150 deg F if that is enough the unit will be independent of he main boiler using a check valve to admit boiler steam when pressure drops. At least this is my thought. I can be all wrong here as I’m not steam educated yet. I don’t really like this external idea as it introduces new mechanics and electronics obviously complexities the limitation of electric only is hampering me I believe but. Have no choice. Actually my though is to take relatively dry air from the compressor and heat it adding energy by using the inductance heater . As the heated air is used by the engines the energy gets converted into expanded volume this air would be oiled or treated as real steam since I think it will be essentially dried by the heating process. The kill condensate can be evacuated by blow off with by preset check valve or manually in other words at a certain higher pressure the checknvalv would open and clear any condensate. This would be very hot just as RR BOILERS ARE it would go into a condensate container . The steam world call these economist or condenser I think . That’s my though . Again I may be wet steam here so help me If ossible. Guess the way I see it the fire box is an external superheater. What I’m proposing is just a different way to achieve the heated dry steam . I’m right in the middle of assembling these two engines I just stepped on the #51 drill bit I dropped on the carpet last night so I now have red condensate coming out of my foot I’m installing a special check valve called a bandaide with some owdered sealant.
Dang that hurt .
I want to try and get nearly complete assembly today
