Re: Spark arrester design

A screen will not stop 100% of the sparks. But it will catch the bigger ones that are most likely to reach the ground and start a fire. A centrifugal arrestor such a Radley & Hunter stack or a Baldwin Rushton stack is designed to swirl the sparks around internally, until they disintegrate into small...

Re: Spark arrester design

I think I used 6 X 6 mesh size stainless wire cloth from McMaster. It has openings that are about 1/8” wide. Seems pretty effective. But then, I live in the Southeast!

Re: 1" U in 1/4" copper tube

Re: How do you guys feel about the "Just get it done" attitude?

I interpret the “get it done” statement differently. Sometimes the most efficient way to get something done is with a file or a grinder than with a milling machine. It depends on the accuracy required. I’ve “turned” decorative parts in a cordless drill against a sanding belt! Who can tell? Another e...

Re: Alco drawings

The late Bill Bursey of Clifton Forge VA built a 7.5” gauge model of one of these from C&O blueprints. You might contact the C&O historical society to see if they have the prints he worked from. The engine he built is on display in their museum in Clifton Forge.

Re: Blower

One thing not really discussed in this thread is the difference between propane and coal firing. With propane, not much draft is needed, just enough to clear the combustion gases from the firebox.

Re: Eccentric Engineer Announcement - Small Scale Injectors in stock!

Very interesting horizontal installation. Does it matter in what orientation the injector is installed?

here is another way of doing it that works well too but more bulky. This design doesn't heat up or soot up the fan.
Fred,
With this type blower, how far does the smaller pipe, coming in from the side, extend up inside the larger pipe?

Re: 3d printed parts

what is the shrinkage allowance given for making a pattern to cast in bronze do you need to allow percentage bigger in your master. The shrinkage allowance for patterns is generally about 1 - 2% depending on the metal being poured. This is in addition to any machining allowance where the casting re...

Re: Formed cab roof angle 16 ga. steel

DaveD really does fine work. The bronze color on the SS ashpan is from heating it in a heat-treating oven until a light brown is achieved, as I recall.
