In that case, I assume that the pump just runs until the steam times steam piston area equals the air pressure times the air piston area and it stalls. I guess then you want the reservoir to be large enough for a couple of applications to allow the steam pump to recover the reservoir. Hard to say, d...

Are you charging them with an electric compressor with pressure switch? If so, the only thing the tank size determines is how often and how long the compressor comes on. Small tank: compressor cycles often, runs for short time. Large tank: compressor comes on less often but runs longer. If you have ...

If you are by chance measuring propane burner pressure: Since low pressure gauges tend to be expensive I place a needle valve between the gauge (25 psi) and the burner and close the needle valve until I have a usable reading (11-12 psi) when the burner is at full usable fire. I really don't care wha...

Tapping: The video isn't clear enough for me to see the shape of the tap. I regularly tap with a hand drill if not tapping very deep (which he didn't) and the hole is through or at least overly deep to catch chips. I use "spiral point" ("gun tap") taps whenever possible - they are great! ... even 6-...

St. Croix Railroad (Hudson, WI) has a high line for gauges 1" and under I think. Not exactly sure of the assortment. They also have a large 1" ground track and a 7.5" ground track (both w/bridges/tunnels).

etsy wanted me to register with the site to contact him but I didn't want yet another login to remember. Not looking for built units (we will cast them from resin), just looking for 3D model or one to use for rubber mold. If he is interested, can you/he PM me?

Has anyone done a 3D model of a 1/8th scale signal cabinet/hut that they would be willing to share?

I'm looking for a ground standing unit to cover up some non-scale signal conduits.

The only 'For Sale' section I see is very general For Sale (lathes, etc.). Is there one here for Live Steam related items? I know about Discover Live Steam.

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.

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.
