It’s that time of year when Lulu, Midlana’s printer, starts its annual discount season, and right now, it’s 25% off at checkout. Discounts vary day to day so it’s smart to keep an eye on them (they don’t inform authors). The sale typically extends into the first couple of weeks into December, so now’s the time to hint what you want for Christmas.

On the lathe front, I received the interface board and everything is up and running. The first attempt at threading lead to some head scratching before figuring out that the software was unaware of my 4:1 gear reduction, plus, I had the servo driver box configured wrong, go figure. Got that sorted out and, dang, it works. Only thing left is to come up with a cover over the controller assembly to keep chips out of it.

On my drive home, I go through this stop sign everyday, and everyday I puzzled over this and finally decided to share. Typically, a car doing a burn out goes straight or slews left or right, but not back and forth. Once moving, some cars with independent rear suspension will slew back and forth (“fishtailing”), but not at the start. Given where the burnout starts, maybe it’s a FWD car and the driver’s just turning the steering wheel back and forth… Shows what I know, having never owned a FWD car, hah.
