Re: Safety valve location

Mike, Iam no expert, but I’ve always heard the safety should be located at the highest point in the system- which allows it to gauge highest pressure. Hence the steam dome is the ideal location. Maybe someone expert in boiler design can join in and clarify...

Biofuel coal test at Burke Valley RR, UK

Normally I would post in the Grand Scales threads, bit this seems more widely applicable. Very interesting test of biofuels as a replacement for coal, in UK Heritage Steam Railways... https://www.railadvent.co.uk/2021/06/norfolks-bure-valley-railway-tests-new-bio-coal-for-steam-locomotives.html?fbcl...

Re: Anybody experienced with P3 .035 wire?

BDD, Iam traveling at the moment, won’t be able to double check until next week. But Iam sure that’s what the Airgas guy told me to do when I picked up the machine. I did see a welding forum comment that said smaller welders with 1/2” nozzle diameter used 15 cfm, and larger ones with 3/4” required u...

Re: Anybody experienced with P3 .035 wire?

Yep, I misspoke. It is indeed CFM, not psi. So set up at 50cfm. What Miller recommends for this particular machine...

But I don’t remember them differentiating between horizontal and vertical. See to check that...

Re: Anybody experienced with P3 .035 wire?

Thanks Andrew, High voltage, low wire speed sounds right, but worrisome as I was welding fine for an hour or so before this started to happen. I was doing vertical down on a new spot on the frame. And didn’t get a chance to even start the puddle before watching the magic blue flash. Several times in...

Re: Anybody experienced with P3 .035 wire?

BDD, yes correct tip and wheel size. The machine is so new I don’t know what is normal or not. It does seem like the spool of wire was not turning at a uniform rate... although I read miller’s have a slow speed start up wire feed. Still it seemed jerky at times. Also all my problems were with the gu...

Anybody experienced with P3 .035 wire?

Hello All, Just bought a new Millermatic 255 mig welder. I set it up with an 11 # spool of P3 .035” wire from Airgass. Have had nothing but trouble with the wire... or machine, not sure which at this point... after about an hour of doing a bunch a short welds on 3” steel channel, experienced numerou...

Re: 2 ft. gauge train project

I am restoring a 2 ft gauge railroad track I built in the 90's. I want to use something different than 4x4 wood cross ties. One other option might be to consider using cement ties. We have an interesting thread going on the railroad fora at the moment about cement ties. Making and using etc. looks ...

Re: Building a pilot for 2 ft. gauge Forney locomotive

Cool project. it possible to post a pic of the front end? What ever exists now? Probably would give the membership context to respond to your question about the pilot. So much of the hobby can be freelance design, so you have a lot of freedom to do what e we suits your needs. I e see. Is catchers ma...
