Re: Best Book to get Started in 1 1/2 gauge

I agree with willy, start talking to (or listening to) people who have built locomotives. Also start grabbing up magazines (Live Steam, Modeltec, ME, EIM) and read read read. In my experience no one book will cover everything. Joe Neslon's book while a good overview and resource shouldn't be taken t...

Re: British Steam

There are several reasons, a principle one being to allow locomotives to pass within the relatively small (compared to the US) loading gauge. Most stations in the UK had platforms; typically passengers stepped directly onto the platform from the coaches, rather than down steps and then onto a stepst...

Oxy-Propane

I have just now skipped over from the Livesteam board so this question may have been covered. I want to look into changing over from oxy-acetyl to oxy-propane as primary heat source for large (up to 6" diam x 18") copper solver soldering work. I presently have a Victor "Super-Range" torch and regula...

Re: Lubricators in 3/4 scale

Some 30 years ago my live steam mentor, who was a superb machinist, built an 0-6-0 in 7-1/2" ga and elected to install a hydrostatic drip feed lubrication to an LBSC design (I don't recall which one), using a separate lubricator for each cylinder. Although beautifully built, and exactly to the "word...

Re: Steam Hammer

About fifteen years ago on a road trip to Chattanooga TN, I had half a day to kill so I wandered (on purpose) into the abandoned remains of the Ross-Meehan Foundry (ie Meehanite) and the only thing in the way of equipment left in the entire plant (other than the pattern sheds which were FULL) was gi...

Re: Lubricators in 3/4 scale

The beginning of this thread was "lubricator or no lubricator?" and my opinion is that a hydrostatic would be better than none at all, however I agree with Phill that in the scenario described the oil delivery would be essentially constant, and also that for a "working" engine a mechanical lubricato...

Re: Lubricators in 3/4 scale

I see several problems with this scheme, first you propose a continuous state steam supply (ie from the turret) which (a) will amost certainly allow oil to be drawn back into the boiler, and (b) not shut down when the throttle is shut off. Next, a hydro-lubricator works by displacement (also called ...

>>Too simple

John, I went through exactly the same exercise when I started, but I elected not to build Raritan not because it was too simple (although it kind was) but because 7+ ga was the only local track available and our club discouraged anything but 7+ ga.

Re: Craftsman Lathe Motor Size????

I have had two Atlas lates, a 10" and a 12", which had 1/2 and 3/4 hp motors respectively and I never wanted for power for the work that I did - large scale (7+ga) steam engines. I agree with the comments on the ability of the Zamak gears to endure much more than 3/4hp but one thing hasn't been ment...

Re: Lubricators in 3/4 scale

Yes, it's very often about being clever. Keep in kind that hydrostatic lubrication is a function of condensation and change of system pressure induced by steam flow to the cylinders. When there is no flow, such as when the throttle is closed, the flow will stop because the system will reach equilibr...

Re: Lubricators in 3/4 scale

Yes, Chris is right, in fact anywhere that oil can be introduced equally into the steam supply to the cylinders is OK. BUT documented experience (by many others) has shown that when ONE lubricator attempts to supply two cylinders in that way, that is feeding oil directly to the steam chests through ...

Re: Lubricators in 3/4 scale

You'd have to address any given locomotive individually, but essentially the lubricator could be located anywhere you could gain nearby access to a live steam line that provided equal flow to both cylinders, that is before any split. I've seen locomotives with the lubricator located under the pilot ...
