	Heron Marine Steam Engine Ref: MO10001 The Heron, is a double acting, slide valve, twin cylinder 3/8 in bore, 3/8 in stroke steam engine. We have chosen to use a Stephenson linkage for reversing due to the smooth ease of motion, which is great for servos. Not to mention they just look great. All steam intake and exhaust outlet thread sizes are 1/4 in-40 and use 5/32 in copper tubing for plumbing. The Heron features dual displacement lubricators for even oil distribution and longer run times. A built in throttle valve which can be operated by a servo, controls engine speed. The crankshaft is supported with precision grade, sealed ball bearings to ensure a smooth long lasting hassle free work life. The Heron's output shaft size is 5/32 in or 3.98mm. This gives you the flexibility to either use metric or inch type universal joint for shaft connections. The Heron is constructed from varying grades of Brass, Bronze and Stainless Steel. We do not use any materials that would rust in a marine environment. A great deal of research went in to choosing materials that would be compatible with one another as well as withstand premature wearing. Machining finishes were also a great concern while constructing the parts for the Heron. Not only for cosmetic reasons but more importantly wear mating and sealing issues. All of our parts are made either inhouse or from local machine shops in the United States so we have complete control over their quality from start to finish. Every measure has been taken to reduce weight as well. The Heron only weights 15 ounces including the water pump. The Heron was designed to run on varying pressures from 10 psi. to 100psi. Each engine is hand assembled per order. The picture of the Heron Twin shown above features the shaft driven water pump which was designed to compliment both the Heron's performance as well as it's appearance. Water pumps are for modelers who wish to extend their steam plant's operating times. The water pumps bore is 3/16 in and the stroke is 1/8 in. The water pump intake/oulet thread sizes are 1/4 in -40 and use 5/32 in copper tube for plumbing. Please note that the water pump is not included in the price shown but is available in the related products section. The Heron is also available as a right and left hand mirrored pair.
