Re: Station, Road, Steam Stafford locomotive

You might have a look at this account, which looks to be generally complimentary of the locomotive, and I've never heard a negative whisper about Station Road. http://www.gentoosjournals.co.uk/

Re: welding boiler

To answer the second part of your question . . . ideally stays should be perpendicular to flat surfaces and co-radial to curved surfaces, and also symmetrical. That is, identical on both sides of the firebox. That's the ideal, but things don't always work out that way. You can see in the illustratio...

Re: Understanding types of copper?

I think you've mis-applied Harris's flue formula which should be D² = L/55 to L/75. The object is to solve the equation (find "D") for a range of constants between 55 and 75 which has been proven to produce the optimum balance between gas flow and heat absorption in a fire tube. For L/55, D = .330"....

Re: Understanding types of copper?

I would agree with Soot on all counts . . . see your local pipe supply/plbg house and order seamless rigid Type K tube, or McMaster-Carr should have it. I always use Type K for it's thicker wall and, assuming good initial workmanship and proper care later, a longer life expectancy.

In Trade for #0-80 Nuts

I need a few dozen #0-80 nuts and have a quantity of Unbrako #2-56 x 1/2" Allen head alloy screws to trade. The nuts need to be either stainless or brass and scale or near scale hex.
Anyone have any #0-80 nuts lounging uneeded in a drawer?

Re: New Year.....New project

I sometimes refer to it as a Domino effect, . . one job has to be toppled, in order to start the next job, which in turn will cause another to topple, etc. I'm in the middle of a row of Dominoes right now and life keeps adding Dominoes to the far end.

Just thought people would like to see what can be done on conventional/manual machines. Jack Bodenmann does it all the time.
I like to. Well done Don.

Re: Un Lucky 7 Stack

This is not a knock on elm53, but are we now to the point where we assume that such a challenging and well-done piece must have been (or was probably) done CNC, and a disclaimer added to the description, rather than to assume first that someone using the skills and experience they've acquired has do...

Re: 3-1/2" OS Porter Live steam need help

FWIW . . . the ISO60 hydraulic oil works just fine on Gauge 1 (3/8"/10mm scale) locomotives, although it's probably in the upper half of the viscosity range for that gauge.

Re: 3-1/2" OS Porter Live steam need help

Correction . . . the oil I've used isn't a Chevron product but Mobil "600W Super Cylinder Oil" which is ISO 460. It was the only steam oil available off-the-shelf from the local petroleum distributor, aside from Shell Valvata, which was only stocked in 55-gal drums!
