My Long Trail

I began to realize how excited I was only a couple of days before I left. I could hardly sleep for thinking about my upcoming trip. Meal plans and other logistical details kept spinning through my brain; the last I checked the clock was 3:55 AM. This is actually good I think. I’d been casting […]

Zigzag wrapup

Phew – the polyurethane was drying on my last Zigzag chair while I wrote this post. It’s been a fascinating process, and I’ve learned a lot. Some questions got answered: the chair does not collapse under you when you sit on it, as numerous testers have confirmed, although it does bounce in a way that […]

ZigZag fanny test #1

It’s been a while since my last update; I’ve been traveling, and I hit some snags in the production line. It turned out that the clever joint I created just wasn’t going to work, and I decided I really did need to bolt the acutely-angled zigzag joints, as shown in the first fully assembled chair […]

All seated

Finished up the joints for the remaining seats this weekend. Ellen didn’t think I was giving an honest portrayal of the working conditions in my shop, so here’s a full view, showing all eight seats in situ. I’m relieved to have finished these joints, probably one of the more exacting tasks in this project. The […]

first few joints

I forgot to post these awesome photos of the zigzag bevels from a few weeks back. It was a joy cutting them with a new supersmooth sawblade with lots of teeth. The clamps hold the piece tight to a board that slides along the saw’s fence. Without this only a tiny edge would be riding […]

half-blind compound dovetail

Just a quick update on my progress; I bought myself a new 1/2″ dovetail router bit ($20), and got to work cutting the joints. Almost half the time spent planning, setting up, and cutting tests. The first picture below shows the setup: In the next picture you can see the results of a few hours […]

zigzag chairs

Some friends (well, one friend) expressed some interest in the chair project I crowed about on facebook recently. So I decided to document the project here. The idea of making a Rietveld Zig-Zag chair was my father’s: he conceived a desire for one, and bought some books and plans. I think he was attracted by […]


I recently registered with Why? It was cheap. Lesson learned (again) – there’s always a reason for cheap. I eventually decided to consolidate this domain with some others I have registered at (an excellent provider). When I tried to transfer, I found out you need an authorization code to effect the transfer. […]

Multithreaded testing with JUnit

This post demonstrates an easy way to test the effect of multiple concurrent threads running your software, using your existing unit tests. Have you ever wondered whether your software is really thread safe? Whether it will stand up to the punishment of thousands of concurrent users when your site (or app) goes ballistic? Multi-threaded programming […]
