Build the Snow -- A Tandem, Double-Acting Engine

By Doug Kelley

Doug Kelley's very popular Snow natural gas pumping engine, as an internal combustion engine construction series, first appeared in The Home Shop Machinist magazine. An ample supply of back issues in which the project appeared soon sold out -- encouraging reprint in a booklet format. The resulting 44-page plus cover saddle stitch volume includes 13 pages of photos that showcase full-size Snow engines housed in museum settings around the U.S. -- some that run and some that are being restored with the intent to run.

Crobalt Solid Round Bit 3/16"x1-1/2" L

These Crobalt tips are 3/16" x 1-1/2" with round ends to be ground to the correct angle by the customer, using the Diamond Tool Holder grinding jig that comes with each tool holder kit. This size is appropriate for the users of the new ML8mm Diamond Toolholders, designed for the small bench top lathes, such as the Unimat, Atlas 6", Sherline, and other new Asian lathes.
Crobalt cast alloy is an alternative tool bit to the HSS tips usually used in the Diamond Tool Holders, its ideal for turning tough materials such as stainless, cast iron, and high carbon steels. Tougher and less brittle than carbide it can be ground using a normal aluminum oxide wheel, Crobalt contains 50% cobalt with the remainder being tungsten and chromium, there is no iron or steel in the alloy.
Watch the Diamond Toolholder in action doing a comparison test between M42 HSS (CoHSS) and Crobalt cast alloy -- both toolbits are 1/4" square.
They are being used in a Right Hand 12mm model Diamond Tool Holder, to turn 304 and 316 stainless bar and an interrupted cut on a piece of cast iron.

Figure It Out - Common Sense and a Calculator DVD

By Rudy Kouhoupt

Did you ever wonder how high the valves should lift; what happens when you scale it up or down; how big the inlet passage should be; why small engines run so fast; how heavy it will be; how the flywheel effect changes with size; how to set your lathe for greater accuracy; or how to check tapers and angles? Rudy describes and illustrates his real world approach to problem solving on these and other subjects in the shop and at the drawing board. He includes an outline and drawings of examples used in the DVD presentation.
Watch a brief clip from the DVD.
