Re: 12" working railroad

I wasn't happy with the tie stain as it was too "redwood" so I added some more black to it. It's not marine enamel it's Rustoleum flat black enamel. It seems to mix with the boiled linseed oil and stain really well. It only took about a pint to get the entire batch this dark. The sample piece has be...

Re: 12VCompressor for a Brake Car

I have a question for you all, is there a lower pressure 12 volt pressure switch available? My brakes are going to be air pressure applied to release them and I'm using 1-1/4" cylinders so I don't think I will need more than 60-75 PSI. All the switches seem to be 95-110 or similar. So that unloader...

Re: 12" working railroad

Oh, the other thing I got done was modifying the coupler for the locomotive with a top pull cut bar pin/eye. The Tom Bee coupler has a little dimple in the casting, making it really easy to drill through with a clearance hole and then just peck a drill mark on the top of the sliding bar inside the c...

Re: 12" working railroad

Thanks SPSTEAM, this has been a fun build using and re-purposing the parts and scrap I can get my hands on for the most part. We had plenty of scrap sheet metal strip laying around, but there was just no way to form it into the hat channels for the ribs anywhere close to the right size. The square b...

Re: 12" working railroad

I like the way it allows the trucks to articulate yet not allow leaning, so that the trucks will align themselves to the track independent of the spring movement. I'm waiting for some parts to arrive for the muffler/air tanks, so I hopped over to the riding car and started fitting up the sides of th...

Re: 12VCompressor for a Brake Car

There was a man that was critically injured and did not survive when some plastic air plumbing exploded. Even the polycarbonate bowls on moisture traps and oilers have warnings that they may shatter and should be replaced periodically. For compressors, I have the larger HF 12 volt compressor, and h...

Re: Stainless steel boiler/exchanger?

I've found that moving fast and stuffing rod is the key to TIG welding SS, as it keeps heat down. If your bead starts turning brown its too hot, I shoot for a silver/gold color with a little blue being the "warning". For something like this I would probably tack the tube sheets in, then cap the tube...
