Tiny Power

Tiny Power was founded by Charles "Pop" Arnold of Junction City, Oregon, in the mid 1940s. He was a perfectionist in anything he did and one of his models was even exhibited in the Smithsonian Museum for several years.

Mr. Arnold died in 1975 and Gene Goebel of Branson, Missouri, purchased the Tiny Power business from Mr. Arnold's son in 1977. Mr. Goebel expanded the product offerings over the years, including the addition of several of the popular small engine models offered today. He also experimented with modifying the "M" engine to drive a generator to produce electricity, and built one in 1978 that he still uses in his shop, primarily to run electric heaters in the winter.

In early October 2004, Tiny Power again changed hands. The new owners are Ronnie and Deanna Baird of Bealeton, Virginia.


Tiny Power makes an excellant Single Cylinder Twin Flyweel steam engine kit that must be machined

Bore:    1.25"
Stroke:    1.5"
Shaft Size:    .375"
Flywheel Diameter:    5.25"
Overall Height:    5.5"
Length Base:    11.25"
Width Base:    7.5"

The Ajax according to the Tiny Power web site is the most beautiful of all of the Tiny Power engines. A single-cylinder horizontal slide valve steam engine, the Ajax was modeled by Pop Arnold after a famous turn-of-the-century engine of the same name. The engine is quite robust and capable of useful work. With the exception of pipe fittings, the kit is complete and contains everything needed to build the engine, including cast-iron piston rings.   I purchased this engine on eBay and other than adding a few fittings have not done anythng to it.

Little Kathy

Bore:    5/8"
Stroke:    3/4"
Flywheel Diameter:    2.5"
Overall Height:    5.25"

Little Kathy is an excellent project for the beginner according to Tiny Power. The engine was introduced originally in 1926 by Mr. H.J. Coventry and was featured on the front cover of the October 1926 Modelmaker Magazine.

Included in their kit is a copy of the original 1926 blueprint, along with an updated blueprint by Ed Warren of Modeltec Magazine. Mr. Coventry wrote an article on how to build this model step-by-step with very basic tools; files, drill and small lathe. A reprint of this is also included when you purchase the kit from Tiny Power.

I acquired this model on eBay. It needed a few parts and cleaning to get it to run. It now runs very nicely on about 4 lbs of air or steam.

1 V10

Bore:    .75"
Stroke:    .875"
Flywheel Diameter:    2"
Overall Height:    6.5"

The 1V-10 is a vertical version of the H-10, and is quite capable for use in working models such as radio-controlled boats, or generators. It has a smaller disc flywheel, lending the engine to high speeds, Note the extensive use of castings rather than machined barstock, enabling a more accurate appearance of a stationary vertical steam engine. All castings are in bronze and scale nuts and bolts are included along with all necessary parts and well-detailed, full-size blueprints to complete the model in short order.

I purchased this on ebay and have only added piping and it is a smooth running engine.
