Datsun Roadster

I’ve always been a car guy, but unfortunately haven’t always thought to take photos of my cars. I don’t have any pictures of the little Honda Trail 70 motorcycle that I rode all over Glenrose Texas when I was 8, or of the bigger Suzuki 90 that I graduated to when I was 12. And I really wish I’d taken a few pictures of my first car, a Datsun Bluebird sedan, which I bought for $25 when I was 15. I had to rebuild the transmission which was a great lesson for a kid to learn.

While I was in college and working part-time in a machine shop I bought a beat-up, non-running car, this Datsun Roadster. I built it an engine with the help of my brother and dropped it in, painted and finished it myself, and drove it for several years. Wish I had some photos of the process, and a better picture of the end result!

Mini Baja 1982 Team

miniBaja-2The University of Texas at Arlington fielded two teams for the national Mini Baja design-build engineering competition in 1982. That’s me third from the right, on the 3-person team.

Our team captured first place in the national competition that year, which was held at Texas Tech in Lubbock. The girl on our team at the far right is Lisa, my future, current, and forever wife, so you can see that joining the team had far-reaching consequences!

SAE Race Team 1984

Our SAE TeamAfter being part of the Mini Baja Engineering Team competition in 1982 I jumped at the chance to join the Society of Automotive Engineers Competition Team at the University of Texas at Arlington for the 1984 competition, which was held at our school that year.

tomSAE-4Like the Mini Baja, this was a design, build, and race competition, and, need I say it, our team won first!

I even got the wheels off the ground in a few of the turns! Here are a couple of race pictures and a few close-ups of the car:

Ball Turner Manufacture

Starting Work in the Shop

03-squaring_blockThe first stop in the machine shop for all projects is cutting the stock. Here I’m squaring up a piece of hot-rolled mild-steel round stock in the band saw to make the ball turner body. The cant being removed in this photo will be further sawn to make the rotation stops.

Ball Turner Design

This entry is part 1 of 2 in the series Ball Turner

There are times in the machine shop when you need to make a spherical ball out of metal. You can form grind a tool and plunge the sphere on the lathe, or like Reed Streifthau of the Quorn Owners Yahoo Group, you could use an inexpensive import boring head to make a ball turner. Starting from Reed’s design, this page attempts to document what I came up with.

Inspiration and Design

This entry is part 1 of 4 in the series External Hone

hone53As I was working on my Hodgson Radial, I needed to accurately size the crank journals, but I didn’t want to risk tapering the ends as usually happens when polishing with sandpaper. So I made myself a set of external hones (photo of my set on the left), based on a set that I remembered seeing on Ron’s Model Engineering and Model IC Engines website interestingly named the Nikapena Hone.

Timberframe Advanced Week

This entry is part 2 of 2 in the series Timberframing

timberframe55_lgThe beginning of the second week, the Advanced course.  This course really tested my trig skills.  Truth be told, only two people in the class had a really good understanding of the trig needed for this week, myself and one high school kid attending the class!  All I can say is what a lucky kid to be able to partake in something like this.
