Photo of The Day

Currently almost all wells, test holes or blast holes are drilled using a rotary type drill. But in the early days they drilled using an up and down motion. I guess this might be called impact drilling. Anyway, the first powered drills of this type used a "walking beam", which converts the rotary power from the engine (originally steam engines) into vertical motion.

The first and possibly best known example was the Keystone Driller. You can see a video of a restored Keystone Driller in action here:

I also have some photos of two Keystone Drillers on my website. One was abandoned in place while drilling at a mine and is slowly rotting away. It's engine is missing. The second is complete with vertical boiler and steam engine, and is displayed at a museum in Ely, NV:

I just found a bit more information about this type of drilling. Apparently they were also called "cable tool rigs":

Found this little tractor at the Brooks Steamup in Brooks Oregon this weekend.  Looks like it would be fun to model.

If you are in the area and are interested, the second weekend of the steam up is next weekend (first weekend of August).  $12 bucks admission and probably plan on two days to see it all.  I was using a walker but found it difficult to navigate the gravel paths. I should have used a cane although sitting places are at a minimum. This show is well worth the admission. At about 1:30 they have a parade of all of the various tractors, antique and new.  Bring sun screen and a large brim hat. Temps about 90F.

Cool little tractor!

Here's a site I just came across that has some interesting photos of stationary diesel engines, mostly from the 1930s:

Here's a prototype that epitomizes all the guidelines for modelers to 'model the typical and commonplace' or it's an example of some of my attempts at subtle weathering This shed "stands" attached to the back of a brick factory in Troy, NY. Until recently it was mostly hidden behind weeds and shrubs.

As any real estate agent would say "move in ready".

It's all location, location, location. Don't laugh. There are burned-out, condemned houses here in the Bay Area selling for over a million dollars.

When you read the articles, what is for sale is actually a lot in need of clearing before a new house is built.  Given the demand for housing in the area, housing prices are rising at a rate close to a week's pay every week.

[Greg Hile]

Lawton, you're absolutely correct, it is usually the lot they are after -- even ones where there's nothing wrong with the structure. Palo Alto, in particular, seems to have a bunch of small, older homes that were in fine shape and were sold and torn down. Had a friend that did that, and that was 20 years ago ...

Here's a vintage B&W photo that has been beautifully colorized. It would make an interesting model, though it would be tricky:

I've seen her work before, and it is quite wonderful.
