Re: Hydro Testing

Pump away with whatever you have = water pressure is water pressure, you don't need (want) a lot of flow. I would put 50 psi in it and look around inside the firebox for leaks - which is where those castings habitually caused problems. If you are good at 50, then work your way up slowly to working p...

Re: Hand Pump Drawings and Castings

Folks are missing the point about boiler diameter... you only have to pump IN what you take OUT, irrespective of the size of the boiler. So if you are just sitting there and need make up, then a larger diameter boiler (theoretically because you must also consider length) is going to go down slowly.....

Re: Allen Mogul axle boxes?

most needle bearings get a light press fit and can, over time, especially in low frequency / rpm applications, work their way in / out. I pressed mine in very lightly against a shoulder , then put a cover over the end to keep them from coming out. The cover was actually the face of the axlebox with ...

Re: Hydro Testing

HYDROTEST IT at 150% of the safety valve settings

then fire it lightly and give it a run on blocks

some of those older LE engines had cast sections in the boiler that tended to be porous and while it may run on air, may also be leaking in the process.

It isn't soldered with SIL-PHOS solder is it?

Re: Hand Pump Drawings and Castings

Dave: I fail to see what the diameter of the boiler has to do with respect to a pumps effectiveness. If you need water you need water and you use a pump. I was not aware that you size an injector by the diameter of a boiler -> I thought that you sized an injector (and pump) based on steam consumption

Re: Hand Pump Drawings and Castings

AH...well....if you have no place to put it then you have no place to put it is different than people being adamant that they are a waste of time / energy.

Re: Hand Pump Drawings and Castings

I an always amazed at the arguments against a little bit of extra safety.

Guess the same could be applied to seat belts...never been in an accident so do not need to wear them.

Re: Hand Pump Drawings and Castings

If you want a double acting pump to put in the tender, I have drawings at www.mehrs.com that you can build from bar stock

help yourself

I have never felt that having an 'extra pump' (or two) on board is a problem.

If you build it, they will come...

Not all of us, all of the time

Re: Sticky Throttle

Looking at the linkage, I see some areas for possible 'stiffness' improvement When the first rod PULLS through the angle of its connecting link on the right, it is going to tend to want to 'straighten' because the rod is not infinitely stiff. This will create some of the 'slip / stick' you are descr...
