PowerHouse - Page 5 Correction

It has come to my attention that there appears to be a dimensional error on page 5 of the Powerhouse plans. On "Frame Side View" (upper left), the dimension of .281 for the distance from the edge of the frame to the location of the push rod bracket holes, should be ~ .210 to .213 instead.  If .281 is used, then the leftmost pushrod bracket located 2.156" away will be too close to the cam gear.

Many thanks to Jay Bolyard and his son Erik who caught this.  

I'm very surprised that this has not been brought to my (or Dad's) attention until now as the plans have been around since 2001!

Regards,

Allen

Allen,

Thanks again for helping me to solve my hall sensor problem. Even though it wasn't anything more than a bonehead move on my part, it was you who insisted it was the hall sensor leading to me finding the issue.
The below video is my engine finally taking its first breaths of life. Thanks to your father for a great set of plans which allows folks like me to accomplish these builds. I look forward to the next engine build.

Thanks again,
Matt Parker

Dana Hall's Powerhouse

Got this e-mail from Dana Hall on May 23, 2012:

Hi Allan...

Dana Hall here from Florida...

I have finished working on your father's "Powerhouse" engine and thought you

would like to see how it came out...

Took 2 months to make... I got side tracked onto another project from

another plans maker... They looked really good, but were filled with inaccurate

measurements and some of the plan drawings made no sense at all... A real

pleasure to get back to working with your fathers plans again...

Enclosed are 2 images of the "Powerhouse"... Thought you might like to see

them...

Talk with you later,

Dana

Absolutely beautiful.  Love the color combinations he used on the engine, and the woodwork is just splendid.  

No doubt Dad would have been very impressed.

Jerry's Original "Powerhouse"

"The 'PowerHouse' engine is a long stroke design for medium to low speed operation. By having a long stroke, it is capable driving a load such as a generator or pump at a leisurely pace. It is made from bar stock and was designed to be as easy to build as possible while retaining good looks. The frame and base plate is from aluminum alloy plate. The cylinder, piston and head are of cast iron bar stock; and the flywheel is of mild steel. The engine is air cooled by fan (belt driven or electric), although it will also operate without one. Spark advance/retard is adjustable while the engine is running. The carburetor is an easy to build type with adjustable speed control and an air cleaner. The engine will run an hour or so on 2 ounces of fuel." - Jerry Howell
