Tiny Steam Engine

This small steam engine was built from the plans for Elmer Verburg’s “Tiny” engine, which can be found on the Internet. This version has a unique boiler and burner so it actually runs on steam instead of compressed air, which most model steam engines use for safety reasons.  It was built by Jeroen Jonkman who designed the beautiful “Stirling 60″ engine which you can build using his free plans.

How to indicate the vise on a milling machine

“Figbash3″ has a quick and unusual method for indicating a vise in one pass.  He starts with its left side slightly angled towards him.  Then while moving the table he taps the right side of the vise until the pointer on his indicator stops moving.  You’ll understand if you watch the video.  It’s only 3:12 long.

Sharpening Twist Drills by Hand - Part 1 of 2

This is the first of two videos that will teach you how to hand sharpen a drill bit using a bench or pedestal grinder.  Part one introduces Barry Young, a machining instructor at Bates Technical College in Tacooma, WA.  He demonstrates how a drill gage is used and shows examples of some poorly sharpened drills.  Barry also shows some drill bits that were properly hand sharpened and he compares them to some that that were sharpened using Darex and Drill Doctor sharpeners.

In the second video Barry Young moves to a grinder and demonstrates the actually sharpening process.

There aren’t many videos that will show you how to hand sharpen a drill bit and these two are by far the best.  It will take you about fifteen minute to watch them both but it will be worth it if you really want to learn how to do it right.

Sharpening Twist Drills by Hand - Part 2 of 2

This is the second of two well-made videos that will teach you how to hand sharpen a drill bit on a grinder.  The first one talked about it and in this one instructor Barry Young demonstrates how it’s done.

How to polish a stainless firearm to a high shine

The World's Smallest V-12 Engine

This incredibly small V-12 engine is powered by compressed air.  All the parts are hand-made except for the bolts.  For those who don’t know Spanish:

“A tiny V-12 engine with compressed air injection, hand made using traditional methods.  It is 12cc in displacement, the diameter of the cylinder is 11.3 mm, the stroke of the pistons 10mm and it works with only 0.1kg/cm2 pressure.  It is constructed of stainless steel, aluminum and bronze.  Patelo dedicates this engine to his grandchildren: Sara, Carmen, Jose and Pablo.”
