Completed! the colors are all general finishes premixed milkpaint – Klien Blue, Emerald, Holiday Red, and SunGlow. I wanted the brightest colors I could find. Chalkboards were used front and back, because we have carpeting in the playroom where the toy box will sit, and we’re pretty sure that the markers would find there way to the fiber.
If you want to participate in the build this year and have your build count towards the generous donations from the Spaguonolo’s – you can find out more about it, and the plans, at the WoodWhisperer site.

As I continue to work on a small cabinet to hold baskets for my daughter, I’m doing some focus exercises on my dovetails. I teach a hand cut dovetails class at Woodcraft, but I’m no master like Mr. Cosman. Because I don’t do this professionally (outside of teaching), I take every new project with dovetails as a chance to improve my technique. The critical points for the tails is that 1) they are perpendicular to the face of the board, and 2) they stop exactly on the scribe line. By taking the time to practice, I’m trying to continue developing muscle memory, which is a hard thing to do if you don’t do them all the time. And anyways, I don’t know if I’ll ever get to the point that speed becomes an focus, because I do this for fun not for profit.
The next set of tweaks is done on the drawing, we’re going to try to get the new carriage assembly set up and cut out in the next couple weeks, and this time around – we’re planning to mount a Dremmel with a grinding burr as part of the test. (Prior to that I have to make up some blanks with paper taped on, and create a marker holder that can be mounted to test some of the pattern logic out. I’ve uploaded this plan to the 3D Warehouse for those that are interested.
Just updated the drawings to make some of the physical changes we wanted to do. Read more…
I modified the original carriage to accept the timing belt approach. To do this I had to rotate the drive motor 90 degrees and mount a timing pulley on the shaft. The belt needs to thread through the carriage sides, and since it forms a loop, there are two holes on each side. The belt needs to be attached to the drill platform and loops over the timing pulley on the drive motor. The other end needs to wrap around a free turning idler bearing (or a very smooth/no-friction surface). Read more…
The next stage of development is in progress – I got most of the code running on the test jig this week, and once I got it to a point that most functions seemed to work – it was time to put it into a practice jig. But before that happened, I got two micro switches to use to detect when the drill platform hit the far right and left points. Originally, I was just going to mount these so that I could tell when the drill platform hit the ends Continue reading
For those that are interested, I’m going to keep a compiled list of parts, prices and sources for the project here. I already have a couple more parts on order, and if they work out, I’ll update the list to include them as well.
To be able to work on part of a project, while on the road is a bit of a challenge. I cobbled together a jig to hold the controller and motors to allow me to start working on the controller code while I was on a business trip. The gory details are in the update to the pen decorator project.
Ok, I admit it. I don’t just do woodwork. I also like playing with photography, and have a ham radio license (KC8MNS). It’s the latter that got me in trouble – because coupled with my professional background as a software systems architect (computer programmer) and the love of building stuff, even with electronics, I was ripe for the picking… read about it here
