should allow the pressure to rise much higher, there would be power and not so moist steam.

It's incredible that steam engines had this variable valve timing long before cars got it!

Walsch must have been a genius, can anyone explain ,.percentage cut off,.?
@CipiRipi-in7df8 ай бұрын
Very basic, it is the percentage of the piston stroke in which the piston is powered under the steam from the boiler. It can be controlled by the time on which the valve close the admission. For example, a 30% cut off mean that piston move about 30% of its stroke under the steam coming from the boiler (at boiler's pressure). After that, the valve close the admission, and the steam trapped in the cylinder expand adiabatic, under its own pressure. As the steam expand, it cool and its pressure drop, until piston reach the end of the stroke, the valve open the exhaust port, and the steam is pushed out by the return stroke of the piston. Percentage cut off help saving steam (thus saving water and coal), by delivering only the power needed to compensate for air and rail friction.

This valve gear for a steam engine is much more complicated than the gear on a four stroke internal combustion engine.

I've enjoyed watching this video several times. The brass collar to control the self-eject on the tailstock is an excellent idea and I highly recommend it. I've similarly replaced the trip bar locking screw with a small clamp handle, it's slightly different as I've also fitted a swarf guard, bolted to the apron just above the trip bar; this was made from 25mm angle cut and filed to fit, tucking under the overhang of the bed and working well.
