Isn't somebody building one up in Maine, or is that a tender engine?

I think the one you're thinking of is WW&F #9. They're putting a new boiler on it. Not sure if they have plans or not.

I did get a request for patternmaking sources for cylinders recently - perhaps that's why Kelly is asking?

I'd not be afraid to take the cylinder stuff from a 3 footer and simply reduce the saddle to cylinder sections accordingly.

Glovers used the same cylinder patterns for multiple gage orders and changed the saddle sideways width to suit - but unfortunately, to the best of my knowledge no complete set of patterns and core boxes from there got preserved during the emegency shop artifact triage done while demolition proceeded in an ice storm.

I don't know what they're using for blueprints but the WW&F is planing to build a 2-4-4 replica of #7 to be numbered 11. Some offsite work has been done on a pilot wheel pattern and a bell yoke pattern. No real serious work is planned until # 9 is finished, and then only when funding is available.
If there's not a complete set of Glover cylinder patterns and cores, are there patterns and cores from different cylinders that could be used to figure out how to make a set of cores and patterns. The person making the patterns for #11 would find pictures of cylinder patterns and cores very useful.
Go to the WW&F forum for more info.

Mike - any good foundryman and patternmaker worth the name can work up suitable patterns and core boxes from a good set of drawings. Saves a step or two compared to having to measure and draw stuff first, and then make patterns.

I'm not sure that the forney arrangement VS standard framing has any bearing on the design of the saddle and cylinders in any case - and there are some good sets of drawings to start from for more common designs.

If you've got some decent erection drawings for what you wish to replicate, and some fairly close bore and stroke cylinders, you can fudge up some very good drawings for the patternmaker. Do you intend to fabricate the saddle? If so, all you need is the between-cylinder width, fastenings, and location of steam passages to match saddle and cylinders.

I don't have much to do with it but I did send them a little info I had on steam cylinder patterns. It's my understanding that they want to build it as close to the original as possable, including cast saddles/ cylinders.

Kelly,

The Portland Company built Kennebec Central No. 2 (0-4-2 Forney)

I know the Maine Historical Society in Portland Maine has a large collection of Portland Company documents, photos and drawings. Wether or not that little Forney is included or not I don't know but its worth the call, or visit.

Terry

Dont mean to be nitpicky, but if people are looking for information, its usefull to have the correct information! ;)

Kennebec Central No. 2 was a 0-4-4 forney, not 0-4-2.
and the Portland company built quite a few Maine 2-foot Forneys.
Eight to be exact.

7 of the 8 were 0-4-4T forneys, one was 2-4-4T

Mike is correct, the effort to build a reproduction WW&F Ry No 7 is an official museum project, planned to be done as much using original methods as possible.

The engineering "staff" started with a few original Baldwin drawings including an erecting card and have been developing the rest from those -- approximately 2/3's of the drawings are completed.

Please feel free to PM.

The idea of casting is great but it is a good bit more economical to do a weldment for a cylinder of this size..larger ones, lets say for a sp2-8-2, are another story.

OK, in this case the cylinders were cast integrally to the saddle halves. Nothing from Glovers would have been suitable in any case, all their smaller locomotives and much of their larger were made with bolted on cylinders. This is a much more difficult pattern to construct, but certainly can be done if the goal is to replicate the original technology rather than to get a working replica as cost and time effectively as possible.

OSHA probably will limit the extent to which you can accurately recreate a century old foundry, however. Is Knight's back in operation? Bama doesn't have the furnace capacity to melt a heat of iron adequate for this job, and they don't use coke so it wouldn't be authentic anyhow.

Fascinating project - best wishes.

Since you're not looking for a specific engine, I'm not sure what you're planning to use the plans for.

If a live steam set of prints would work for your purposes, Live Steam magazine did a series they called "Lucky 7" back in the early 1980's and it provided drawings of a Forney, I think it was a 2-4-4, but possibly it was an 0-4-4. The drawings were designed so you could build one in 7-1/2" gauge.

Obviously some of the stuff was modified to suit live steam model purposes, but depending on your needs it may be useful.

Sorry I tried to help. The important bit of information I was passing on was concerning the Portland Company Archives as held by the Maine Historical Society. But a simple typo seems to have tainted that information for some folks.

Terry,
no need to get defensive..
if incorrect information is given, it is the duty of all of us to correct it.
no sense in having someone go searching for info on a Kennebec Central 0-4-2!
when one never existed..

im sorry a simply typo tainted the information for you! ;)
