NOTE: this boiler is referred to as "B-307" in some of the plan sheets

A larger version of the 4 - 7 HP Ofeldt, and with a greatly increased pressure range.

This unit is capable of powering the 15 - 40 HP V-4 Single Acting Engine.

The design is to A.S.M.E. (American Society of Mechanical Engineers) boiler power code.
All boilers should be properly pressure tested hydrostatically prior to actual use with steam, and the pressure that steam causes.

* All plans are "shipped" electronically, as PDF files. If you do not have a PDF reader (software to let you look at, even print, a PDF) you can go to adobe.com (never use a PDF reader that wasn't made by adobe, the inventors of PDF), or click here: the One True Adobe PDF Reader - Download.

(Personally, we would turn off their "free offers" prior to clicking the download button [those are for non-Adobe products], but that's your call.)

BTW: "PDF" stands for Portable Document Format. It's just a secure way (the secure way, actually) to move documents around electronically.

HP (in this context) means Horse Power. (Of course you know that; just being thorough.) It's a unit of power equal to 550 foot-pounds per second or 735.5 (or 746 -- believe it not, opinions vary) watts, and is the usual measure of the amount of work an engine can do.

Oddly enough, not that closely related to the amount of work a Horse can do! (Go figure.)
See Does one horsepower really equal the power of one horse? (at www.carkeys.co.uk) for more information on that subject.
