Congratulation on your good showing. Is this the start of a dynasty for Robinson Racing.

Last week I chopped up V1 (version 1) in order to start fresh on V2 for the new year. I thought I would...

The first week of December when I started my frame build was a wake up call. I had gotten pretty good welding flat stock on a bench. Even the short stubs of tubing I was using for practice were...

Finally started the frame build... and promptly threw out 80% of what we talked about. It didn’t seem like I had a good enough feel for what I was doing to convert my paper plan into tubing. I am do...

Nice,

The current frame design looks like it has gone through several generations of refinement:)

I hope the battery experiments yield something useful. As you mentioned earlier, if I run Li-ion batteries, I will probably be in my own class. Rather than keep secrets for a competitive advantage I...

It is great to hear the this project is a place where gearheads and nerds come together to solve problems. I have a foot in each group :)

I spent most of the last two weeks on batteries. The two...

Agreed,

I am trying to be flexible with the batteries so that if they don't work I can fallback to standand SLA batteries.

On the other hand from my limited research it seems that most of the...

Excellent inspiration!

Initially I was looking at the Etek motor. They seem to be the most well understood motor in the sport. However, the market for used Eteks is pretty tight. I take to be a...

Excellent advice on the overlapping welds.

I spend a few hours practicing this weekend. I found that putting eight tacks around a joint and then running a bead from one tack to the next really...

Another update for the week....

Spent the early part of the week assembling and disassembling wheels until I was satisfied with 3 fronts and a rear.

For welding practice I tried to run clean...

Sorry for the steering bearing tangent. I was looking back over my notes and saw that it was thebat that references steering bearing in post #49. I didn't notice that the post was not written by you...

What I found works pretty well for these stiff spokes is to grab the parallel set of spokes and squeeze really hard. An example is at "How to True a Bicycle Wheel - YouTube by Donswoodshop" starting...

I finally started building last week! Got two front wheels put together. The first took seven hours and the second took about an hour. Wheel building with short 12 gauge spokes take a bit of planning...

I was thinking about bearings in general. Something like the booklet my steel vendor gave me. ( http://www.centralsteel.com/images/stories/PDFs/prodguidepub.pdf ) I spend more hours than I care to...

I am reverse engineering your design from this thread. I like your functional approach. Nothing is more complicated than it needs to be. You provided enough information that I am not totally lost on...

Just a quick update.

Most of this week was spent on the basics. I tried to start each day in the shop by spending 10-15 minutes per day practicing welding beads on 20 Gauge sheet metal. I figure...

Thanks Jim,

Sorry it looks like the moderator ate my reply from yesterday. Maybe because I am new and I used a link to an external site :(

In summary... I am from Western Wisconsin, along the...

Just ordered 5 rims, 3 front hubs, 2 rear hubs, and enough spokes for 6 wheels.

I think I will tackle rotor disks and brakes next. There seems to be a lot of good information floating around.

Not only is a least one person accessing this thread.... Your build was enough of an incentive to get me started in the sport!

I am a little overwhelmed getting my mind wrapped around all the...
