The Home Machinist!

I have a full set of un-machined castings produced by Richard Ulin (many bronze, lost-wax castings) for the 2.5" scale Narrow Gauge Mason Bogie 2-6-6T locomotive. For those unfamiliar with this unique engine: http://www.7plusrailroader.com/linda1.jpg http://www.pacificng.com/ref/mason/pdf/Dave-Fletc...

I recently moved a 4,000 pound Haas MiniMill and found it was lots cheaper to rent a forklift and trailer. I had contacted a rigger in the area to just lift it off my trailer and place it 30 feet away inside the garage door and they wanted $1,700 - seems riggers do not want to bother with moves invo...

Fusion 360 is free as long as you certify that you make less than $100,000

For permanent, you want "inches of water" gauge (maybe 0 to 3"). But this is also easily done with just a "U" of clear tubing with water in it for testing purposes.

No disagreement with what you say (been there done that with GE / WESTINGHOUSE, and yes even Zink), but flame on our boilers doesn't realistically hurt...cannot say that I have ever seen a steel (or copper) model boiler that failed as a result of this type of impingement...and cannot say the delam ...

Another benefit of having the tanks/fittings, etc. in water - if there are leaks you'll see bubbles ...

.... Propane forklifts for example circulate engine coolant through the regulator to keep it from icing up. Forklifts (and generators, etc.) heat a device called a 'vaporizer' not the tank. This is because they require large amounts of gas. Liquid is fed to the vaporizer, heated to convert it to a ...

I suspect that even two of those tanks operating simultaneously will have icing problems .... That might be avoided if heat is provided to keep the bottles from icing. If by this you mean 'heat' above ambient temp - It is never advisable to heat a propane tank! Inattention/malfunction can lead to c...

Re: Those valves I listed, when I’m installing the tanks onto the manifold, will gas flow out the other valve (assuming I don’t have shut offs)? I assume yes, because it does not mention a check valve and normally, a grill/whatever that uses these would not need it to have a check valve (i.e.: they...

Also ...

Be sure to use a regulator designed for fuel gas - not an air regulator. The reason is that an air regulator has a vent which is bad near open flame!

As John said, the two cylinders will equalize and equal amounts of gas will be drawn (assuming the tanks are at the same temperature). Note: a) I would add a shutoff on each bottle. That way you can swap bottles without killing the fire/pilot (assuming the other bottle has a bit of propane in it). T...

.... 4) turn off the blower valve - should be no steam shooting out the smoke stack through the blower as you start to move. (Blowers waste a lot of steam - particularity with the LE American’s small boiler capacity. .... Cheers, Glenn It is a bad idea to turn off the blower valve in a propane-fire...
