Flat-pack sawhorses

You’ll have to wait until Monday for the thrilling conclusion to my Wizards and Warriors series. Today on fun-for-Friday FAIC, some thoughts on sawhorses.

I made these light-duty sawhorses out of some scrap two-by-fours in 1997: (Click for a larger image.)

Defying gravity

No tech today, but some fun for Friday.

The 2015 Moisture Festival is over; if you’re not familiar with the festival, it’s a month-long celebration of old-timey and modern vaudeville, comedy, variety, burlesque and circus arts at multiple venues here in Seattle. Hundreds of artists come in from around the world, and often end up staying in my spare bedroom to cut down on their costs. This year I had the pleasure of spending a week with one of the world’s greatest jugglers, Niels Duinker, during the festival and I thought I’d post some links to his videos. When I was a college student I taught myself to juggle, but that was before all the great youtube tutorials that are now available.

Here is Niels on how to do three — start here if you’ve never juggled before.

Back in the day I got a few pretty solid four ball patterns going but I never managed to get more than eight throws with five, or six throws with three in one hand. Maybe I’ll give it another shot!

Melting aluminum

Today another in my ongoing, seldom-updated series of posts about building my own backyard foundry. Today I’ll describe how the final step works: actually melting and pouring the metal. First, see my previous post on how to make a green sand mold.

Start by assembling all the equipment you’ll need in one place, on a day with no chance of rain. (Click on any photo for a larger version.)

Casting: making a green sand mold

Today another episode in my seldom-updated series about building a home aluminum foundry.

The technique I use for casting aluminum is called “green sand” casting not because the sand is green (though the sand I use is in fact slightly olive coloured) but because the sand is moistened with water and clay rather than oil. I made the sand myself; it’s a mixture of about ten parts olivine sand to one part finely powdered bentonite clay, and then “tempered” with water¬†until it feels right. (Use a spray bottle set to a fine mist and stir the sand as you temper it.) It should feel like perfect sand castle building material: wet enough to hold its shape but not so wet that you can squeeze water out of it. If you can make a “snowball” of sand with a fist and break it cleanly in half, that’s probably good. Continue reading

London and Budapest

I recently spent a week visiting customers and giving talks in Europe and holy goodness, never have I been in so many countries in so little time. I flew from Seattle to London, changed planes, flew to Amsterdam, visited customers in the Netherlands and Belgium, then took the Eurostar from Lille back to London, and that was just the first two days!

Funniest Hungarian joke ever

No computer stuff today; since I am actually in Hungary today on business and it is the the anniversary of the happy event mentioned below, today’s FAIC is a rerun. Enjoy!


I’m back from my fabulous adventures in Austria, Romania and Canada and I had a fabulous time, as you might imagine. We were in Romania for a wedding of some close personal friends who live here in Seattle; much of the groom’s family escaped from Romania during the Communist period and settled in Austria, so we spent some time in Vienna and then headed to Bucharest, and then crossed the Carpathian mountains by bus into Transylvania for the wedding. Some of the highlights included:
