Re: lubricator oil

A question this raises in my mind. and one I've not seen asked or addressed (it may have been, I just haven't seen it) is this . . . does steam oil have any detrimental effects on O-rings? As for lubrication during testing I think steam oil is too viscous, especially if cool. I use an ISO/60 hydraul...

Re: Forming boiler sheets for three 3/4-in. scale Virginias

Andy, I don't know how I managed to miss this thread entirely, but I certainly echo all of the compliments expressed by most everyone so far. I've always employed extra measures to insure proper form, fit, and alignment, but you've taken the forming process it to a new level. I know what you mean ab...

Re: Copper boiler build on Youtube

Interesting as they are, I was a little disappointed the video contained only static photos and not video of active construction, although I'll admit it would take as long to shoot and view those scenes as it took to do that phase of the construction. The BR standard boilers always made me shudder a...

Re: Piston Ring Question

I've only built a few engines, two early-1950s MGs and a Crosley, . . anyone remember Crosleys? I had the manuals and other information specific to rebuilding those engines so I'm almost certain if there had been any indication there was a "right" way up I'd have seen it. But those were essentially ...

Re: Piston Ring Question

Something I've seen written about a number of times, and accounted for in TD Walshaw's ME articles on making rings, steam rings and IC rings are different animals. Steam rings exert much less pressure on the cylinder walls. I've never seen an article on modifying IC rings to better function as steam...

Re: USPS is a mess...

Hey Dick (Morris), Some years ago I heard an interesting story about mail service to Alaska. A general contractor had a project somewhere in Alaska which required several truckloads of common brick and the shipping costs to the site from lower 48 was astronomical and would cause him to have to defau...

Re: Could I get tips on dumpster diving for materials for your build?

One of the first lessons my first mentor taught me was to be very careful of "scrap" material of unknown alloy and origin. Although I never sustained a substantial loss of money, time, or tools on account of it, I did learn the hard way that "scrap" should be avoided unless what it is is known or OB...

Re: USPS is a mess...

Having worked there for a time in a professional capacity (not mail connected), and seeing 1st-hand why occasionally someone "goes Postal", yes in general the USPS has systemic problems. But considering ALL of the prevailing circumstances which currently affect delivery, of anything, anywhere, by an...

Re: Iowa Class Battleship Machine Shop

Very few. A ship's crew was made up of dozens of trained specialties, in pay grades between E-1 and E-6, E-1 being an inexperienced recruit and E-6 being Petty Officer 1st Class (PO6) with years (maybe decades) of experience. Machine shops would be manned by various grades of Machinist Mates (MM). M...

Re: Cast boiler components

FYI, my last couple of boilers were in 1/8" sheet and I annealed at least 3x for simple bends, more as-necessary for complex (reverse, compound, etc) curves. The guide-line should be to anneal, when the copper stops moving with normal hammer blows . At that point you might be able to get a little mo...

Re: 7 1/2" gauge NYC&HR American loco from Reeves

Matt, I've never heard of one on this side of the pond. That doesn't mean there isn't one, but they would be very rare, considering there are domestic American designs on the US market. You might try contacting Reeves2000 to refer you to anyone in the USA who might have ordered castings or has one u...

Re: Restoring a Little Engines American

Galvanized can be "oily", both literally and figuratively. The "old" way for installers to treat roof flashing and gutters was to (1) wash it with a warm detergent to remove any literal oils or dirt, and then (2) etch it with a mild acid solution, like vinegar, to give the surface a tooth that will ...
