Another option is a water finish - Had a problem finishing a crankshaft - Low Carbon steel with finish issues at textbook speeds on a heavy lathe. Old timer showed me how to set up a broad nosed tool and use a slip stone to hone a flat on tool face parallel with surface. Run lathe at extremely...

When I did this at tech college (40 years ago at TAFE in Oz) they supplied hand made hook tools in 6 mm. rod to hook out the spirals and direct them away. We train never to use fingers for this task, but see it a lot. Again, the trainers with a lifetime in industry and training told us to stand...

I think it's called a 'rocking couple' in relation to the out of balance unbalanced forces. Vertical twin motorcycle engines avoid this by running both pistons up and down together - gains even firing pulse and avoids rocking couple. Some twins (Kelvin J2 and K2 diesels) kept the rocking couple...

Car club members today with older vehicles suffering from ignition woes often have to get their vehicles towed as young roadside assistance techos don't know about points ignition. Set gap to specs (often 0.015" or a business card.) Clean points after with folded strip of abrasive paper - never...

See https://www.old-engine.com/magign.htm plus follow links. My old Union Gas Engine in a boat dated from 1897 and had one of these coils (Cotton covered Copper around iron wire bundle in varnished wooden box filled with wax). These are only a series coil and ran on 4 x 1.5 volt phone batteries...

Assuming 110 volt AC? Could supply be Edison 110 volt DC system? Could supply also be 32 volt DC farm set supply? Also vintage knife switches for DC need 'flickers', which are spring operated rapid opening switch extensions designed to reduce harm of a 'sticky' spark following and burning the...

Around this time ignition could be flame or make+break. System in the plans looks like precursor to make+break but without the iron core induction coil that "makes the electricity behave like treacle". Likely there was enough inductance upstream of the supply to cause the spark to follow the...

I worked on steamships and sand bent steam and water pipes in steel and copper. ESSENTIAL that sand is ABSOLUTELY dry. Use river sand not beach sand. Cap one end and trickle in sand tapping and tamping - Then plug other end. Heat to red and bend focusing heat on inner part so that this thickens...

On most actual small steam engines (<5" bore?) the lower valve rod guide and gland does all the guiding, but over many years wear leads to slop. Larger engines often have a tail rod guide - these are mostly blind and therefore capped to stop leaks. You could thread the OD and fit a cap. Also...
