Data & Pictures

A collection of charts which are useful in the workshop.

FORMATS. Most of the charts are in Excel format, or can be printed directly from the screen. I will add other formats if I find that there is a demand for them, AND I am told what is required.  If YOU want a different format, let me know.

Pictures.

Some pictures of a superb model of a GWR 0-6-0 in 7 1/4" gauge.
(By kind permission of Bob Zoell of California.)

Another beautifully detailed model by Bob Zoell, of California.
This time, a model of a Corliss engine, which is 1.1/4" bore by 2 1/2" stroke, and has an
8" diameter flywheel.

I wanted a picture of a boat, and Bob Zoell once again provided these, which show a steam
powered tug, a model of
the Anteo, an Italian harbour tug circa 1930's, (and which also
illustrate his versatility).

A typical model locomotive boiler in copper.
This one is for  L.B.S.C.'s  "Juliet".
