Well the Roman legions didn’t fight with wooden swords and their armour wasn’t made out of clay. They were tremendous metal workers. The slaves might have been drinking out of wooden bowels but the wealthy had all manner of fine metal utensils and table settings. Archeologists know their stuff...

So what is alloyed with the tin these days to make pewter? Or is pewter effectively extinct? There is a theory that lead had an effect on the crews of the Franklin expedition in the Arctic. The tin can had just been invented and many were taken as stores on the ships. There was apparently high...

Have you got a picture of the saw parting blade? I have often thought about something like that.

The problem is the wildlife markets in SE Asia. Covid is just one of many coronaviruses that circulate in wildlife populations. The genetics point straight back to bats and possibly cats, maybe pangolins. No epidemiologist believes it is anything else. As a person who loves wildlife and the...

The Hemingway site doesn’t seem to exist, my browser can’t find it.

I’m getting junk mail from homefoundary.org. I suspect they have been hacked.

Sounds like your mixture is too lean. Cylinder and piston cooling has a lot to do with fuel intake and atomization.

That video is by Joe Pieczynski (Joe Pie). There are excellent videos on steam engine building by Keith Appleton, This Old Tony, and Blondihacks. All of those are just excellent series, both on the steam engines and general machining. I watch them a lot.

Great cartoon. I have to weigh in on the side of carbide. Having started in the hobby late in life without the benefit of 40 years experience, trying to free hand grind a complicated lathe tool is beyond me. I took some courses at the local community college and the instructor gave up on my...

Lanolin from wolf hair? I think the typo was meant to say “wool”. Although maybe the wolf was in sheep’s clothing?

QUOTE="Richard Hed, post: 344773, member: 39773"] Maybe someone, not familiar with steam engines, hookt the steam inlets wrongly. Does you have more photos? The museum staff are very expert at running steam engines so I doubt they are hooked up wrong. This engine runs regularly over the...

Interesting. Thanks for the info. If they are separate engines they seem to be sharing steam from the steam chest of the bigger engine to the smaller one. The big cylinder has a steam supply entering the bottom front and the smaller cylinder has a steam exit pipe at the bottom rear. You would...

There are doll clothes online for various sizes of figurines. A bit of research should turn up a period coat with tails and ruffles.

Hmmmm, I might lean towards the airplane myself. I was terrified of CNC until I bought a 3D printer. That has been a lot of fun and is kind of like a CNC machine. A motor moves each of the 3 axes. It is a good workout in CAD but the slicer software does all the CAM work. Just push “start”. I...

Looks like Lego has what you need.

The Ag museum in Austin MB has this amazing mill engine that they run during their annual Thresherman’s Reunion. Didn’t happen this year due to Covid so we went and camped there on our own. I got to spend a few days in their huge collections without the usual crowds. This mill engine was taken...

Here is another one. A three cylinder wobbler. Except the cylinders seem to be fixed and the plate bearing the pressure lines does the wobbling. Very weird. Who dreams these things up?

Yikes that would be scary. Was this a piece of pipe or did you gnaw the centre out of a solid piece?

Interesting. The Wikipedia article shows the engine using poppet valves at each end of the cylinder. The engine in the photo looks like a normal steam chest for a sliding valve. I suppose a slide valve engine could be arranged to exhaust pressure from the centre of the cylinder like a uniflow...

In surveying all kinds of steam engines on the net for my own information I came across this one. It has me flumoxed. Looks like a normal slide valve engine but the exhaust seems to come directly out of the cylinder, not the steam chest. Can't figure out how this one works. Anybody know this...
