3/4" scale, 3-1/2" gauge TOM THUMB
The 1940s are back! Here is a classic from the earliest days of Yankee Shop. Coal fired, vertical boiler. A 2-cylinder marine-style style engine powers a crankshaft, and drive to both axles is via gear reduction and a chain drive. Strong enough to pull one adult on a level track. Ideal first-time steamer on which to learn your machining skills. Perfect for that small backyard loop, or "up and down" line in your side yard.
The following is from Friends Models catalogs dating back to the 1950s....
This is a fine engine for a beginner. It does not take too long to build and is not expensive, has been built by several sons and wives. The newer re-designed loco will haul a man and a boy well on a reasonably level track. Minimum tools required, yet a good skill sharpener.
An updated version of TOM THUMB is currently running in LIVE STEAM & OUTDOOR RAILROADING magazine. It remains true to the original in most respects, but has some modern improvements to make it a better steamer, a stronger hauler, and with improved coal and water-carrying capacity. It uses somecastings from the original design, the first of which Friends produced were the wheels. They are available below; please scroll down. Thank you for your interest!
The construction series for "The New Tom Thumb" is currently (2013/2014) running in LIVE STEAM & OUTDOOR RAILROADING magazine. If you'd like to see Lester Friend's original (1941) TOM THUMB drawings for reference and comparison purposes, or so that you might "follow your own mind" (one of Lester's favorite sayings) when building your "New Tom Thumb", they are available below. There are 3 sheets total.

The TOM THUMB wheel castings are identical to the 1940s-era "Yankee Shop" castings formerly available and they are compatible with the newer design. They elimate the need to fabricate your wheels from stock, thus saving time; and will provide excellent practice with machining iron castings. Another benefit is that they'll allow your NEW TOM THUMB to more resemble the 1940s original than it otherwise would. Here is what one builder has said about the wheels:
