The Home Machinist!

Just a thought, but if you travel, a loco of 7¼ gage with wide treads, could also be operated on 7½ gage track. Some of the tracks in Florida are set up for dual gage. The 6.75 inch back to back is a Pennsylvania Live Steamers thing. It provides a thicker flange, which was believed to be safer from...

Hi all, I'm building a 0-4-0 camelback. The drawing for the drivers shows 2 different dimension for the tire width, depending on gauge. For 7.25(which is what I am building) shows an overall width of .875". For 7.5 gauge it shows the IBLS recc width of .750". Anyone know why its like this? Only thi...

WW&F 020.jpg Charlie...you need to come here to Maine where you can not only see the Sandy River and Rangeley Lakes No.6, but you can ride behind her and probably get a cab ride as well. The WW&F Railway Museum in Alna, Maine is the home to the former Sandy River 5 and later SR&RL No.6 and she ...

Dick,
The slippery stuff under the jaws of the rest is a common dodge. An old time machinist told me about that trick and where to get the slippery stuff. I cut strips out of old TIDE detergent bottles that my wife supplies! It works great.

Langworthy only did a 3/4” scale version. I don’t know of anybody that put out a commercial set of castings and drawings for a NYC Hudson in 1” scale.
You can buy the 3/4” scale drawings from Friends/Yankee Shop in Massachusetts.

The Coventry P-7 irrespective of what that article states is 17/32” to the foot.
They called it 1/2” scale as that is what most people called it.

Everyone , thank you so much for your replies. Not very big, but plan on changing the scale 7.5 when finished with this one. You mention “scale 7.5” and I am assuming you are referring to a track gauge of 7.5 inches. I notice that you are in Saratoga, New York. You might wish to consider building t...

The oddball ratio is because the 2.5" track gauge doesn't exactly match half-inch scale.

2.5” gauge for 1/2” scale is more of a British thing. Here in the U.S. designers such as H.J. Coventry designed their locomotives to 17/32” = 1’ scale on 2.5” gauge track.

I don’t have any contact information on Mr. Rezetti...but I do know who built the Hudson. Prior to Mr. Renzetti’s ownership it was owned by the late Jay Duke on Montclair, NJ. He bought the Hudson from the estate of the builder, Mr. Francis Webster of the Pioneer Valley Live Steamers in Massachusett...

Just my personal opinion.....but I think Raritan looks better with the 3 - 1/2” boiler.

Doesn't the Raritan project have an alternate boiler design using larger diameter copper pipe? Why am I thinking that? If so, that might be recommended for functionality. Others here know more. Just a thought... RussN Actually...the original design called for 3 - 1/2” o.d. copper pipe. That is no l...

Chris....they have been out of business for a long time.
