Yes, it’s been a lazy week at the shop (not at work). I got my motor brushes yesterday, though. And the mill now runs better than ever. The first time I ran the motor (at the lowest speed), there was a periodic ringing sound, and I could tell it was some sheet metal hitting some other metal (cooling fan?). We (Pamir and I) opened the motor only, and this time I removed the can (naively, I had thought it was somehow mounted to the bottom, but it was the magnets), and I was right, the cooling fan was warped. I fixed the blades with my hands and a flat head screwdriver, and closed back the motor. I, of course, had to reinstall the motor brushes.
As I wrote in my previous posts, the brushes of the motor are gone, and I need to get a pair or more soon. So, I decided to remove the motor in the mean time. Here are some pictures of the motor and the mill during the disassembling process.
As I decided to replace the metal brackets for the motor mount, and didn’t have the proper parts, I worked on another project last week. I got some 1.5 mm stainless steel sheet today, though. I also got a new dial indicator, since Pamir knocked over and broke the one I got last night (It’s ok, it wasn’t no Mitutoyo anyway. I could have also turned the base magnet on to avoid it).
Last Friday, my Teflon grease has arrived, and I finally installed the motor and greased the shaft. It has good viscosity, sticks good and runs smooth.
This is an Instructable I wrote a while ago. It was featured there and brought me some months of free pro membership. I’m just putting a copy here, since I got my own blog now. Some schematics here (the PIC Mother Card) are very old and crappy. I didn’t know much about PCB design then. I’m a lazy ass when it comes to web stuff, so I put all the pictures in one gallery. Right click and view image on FF, for real size.
O Marvel! a garden amidst the flames.
My heart has become capable of every form:
it is a pasture for gazelles and a convent for Christian monks,
and a temple for idols and the pilgrim’s Kaa’ba,
and the tables of the Torah and the book of the Quran.
I follow the religion of Love: whatever way Love’s camels take,
that is my religion and my faith.

This site has been on and off for the past couple of months. It was because I had problems getting my host (actually a Linux VPS in NY I use for other purposes) and my domain (from another provider, who used to be my host, as well) work together. All my fault, I was lazy and careless, and I was looking for the problems in the wrong places. I think it’s all fixed now. Hopefully I’ll get more visitors soon.
