Live Steam
Single Cylinder "Mill" Model Steam Engine
Fully Machined Kit in Brass, Bronze and Steel
The horizontal single cylinder mill engine is a simple design, yet retains the basic mechanics of engines which powered many mills, factories and mine pits in the nineteenth century.
NOTE: Pictures are of the finished, assembled and painted model, this listing is for the kit of parts - as per per final picture and Assembly Drawing (see Documentation tab above). The optional second flywheel includes a slightly longer crankshaft.
The classic mill engine layout has a double acting cylinder, eccentric driven slide valve and the large brass flywheel offers smooth running and is capable of powering a range of accessories, in a variety of roles. The engine also includes twin split bronze pedestal bearings for the crank shaft and a substantial cast base.
The kit consists of precision produced parts each carefully made and checked to ensure reliability in service.
The cylinder assembly, slider and piston is manufactured from brass and the piston shaft, conn rod and valve from stainless steel so are not susceptible to the corrosion. The piston shaft passes through an adjustable gland and the steam inlet can be on the top or bottom of the chest.
