Our couch backs onto a floor to ceiling window and its back extends past its rear feet. To prevent a silly but expensive accident, I made a couple of wood stops.

Random idea of the day: a phone app that, when in a car, registers potholes using the phone's accelerometer and Emails the local works department with their exact location.

I put the mill engine back together. I replaced the cord packing on the cylinder and valve chest with O-ring. The packing was leaky which was the main reason the engine didn't run.
The piston used an oil seal (great for running on steam with plenty of oil but not so good for running on compressed air), which required a lot oil to work properly; that same oil leaked out through the packing and came out the exhaust, making a mess all over the machine. Over time, this oil attacked the paint, so when I cleaned it, there was no paint left!
I turned a groove in the piston to receive an O-ring, so there won't be a need for so much oil, which should keep the machine clean.
The result is a nice run at about 6 PSI. Previously, a much higher pressure was need to run, even without a load. This new setup should reduce air consumption.
I didn't run it for very long as I put an absolute minimum of oil for this initial test. Next I will take it apart, to get it ready for paint.

Here is the steam engine fully disassembled and mostly cleaned (nuts and bolts not shown). There are two pictures in this album: one in 4:3 aspect ration, suitable for printing and one in 16:9 ready to use as a background image.
Plus two bonus shots, behind the scenes...

Here's the latest patient in the steam engine hospital...
It's been used to power a miniature sawmill, outdoors, for over a decade.
It has a case of severe blow by. Once I have it fully apart and cleaned, I'll find out what it'll take to get it running again.

And it consumes no oil. Why must you all consume oil turbo Volvos, why?

I just replaced the hub on my bicycle's front wheel. It now has a front brake! It has a generator!
It was my first time lacing a wheel: it went better than I expected.
To be clear: my expectation was that it would end up at a bike shop...

+Michael Sliczniak​ the proper technique on that is you put all the nipples on the spokes at the same level. Then go around and get all the side woble out of the wheel first, then go around and make the wheel round by releasing all of the low spots first. start evenly pulling the high spots down. The trick is to pull everything together all the same time so you don't have any tight or loose spokes. You want all the spokes to be the same tension

I made a replacement gasket out of cotton paper to replace the one that was damaged when I took the valve chest apart.
Next up, I'm thinking of replacing the packing cord used on the slide Rods (both piston and valve) by o-rings.

Hm, I may change a couple aspects of a current design.  Thanks!

Progress so far: almost completely dismantled and, so far, no big surprises. One of the two valve chest gaskets survived intact, so I can use it as a pattern to make the other one.
There is some water inside, so I will check with my friend if has a water trap on his air compressor.

It's a classic ice cream shop: what's not to like?

Not as good as it used to be. Maybe it feels that way because other shopping options are now available, especially online.

Great produces. Love the Deli and cold / hot buffet. Some employees have a bit of an attitude, hence the lack of a fifth star.
