"The Heron Twin"
We are proud to announce the "Heron" Twin.
The
"Heron", is a double acting, slide valve, twin cylinder 3/8" bore, 3/8"
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"-40 and use 5/32" 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" 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" and the
stroke is 1/8". The water pump intake/outlet thread sizes are 1/4"-40
and use 5/32" 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. "Special Order" with short lead times.
