With TTTT coming up, there seems to be a fair amount of interest in wheel covers like the ones I made last year (in the photo below). They are very light and do add some speed on flats and downhills.
 

 
I've committed to making a couple of covers, and have the material for a couple more than that, but if there are many others wanting them, I won't have time and material to make them all, but I don't mind helping. There are lots of ways to make wheel covers. Here are instructions on recumbents.com for making them several different ways. These are made out of coroplast like mine, but mine are even lighter. If you want professional looking ones, and don't mind paying more, and a bit more weight, these are nice.
 
The coroplast covers mentioned above are made out of 2mm coroplast, which I wasn't able to find locally at all. If you order coroplast anywhere else, the shipping cost kills you. So, I used 4mm coroplast that I found locally, and split it with a letter opener. This worked well, and made some of the lightest wheel covers around. You can secure it to the wheel either with tape or tie wraps. Tape looks the best, but doesn't much like time spent in a 130 degree garage. I don't mind giving some instruction (a wheel cover making party, maybe?), but if many people want covers, we'll need more material. The only local place I found with a stock of 4mm coroplast at a reasonable price was Regal Plastics. I paid $18 (~$20 after tax) for each 4' x 8' sheet of coroplast, and they have a $50 minimum order. A 4' x 8' sheet would make either either 4 or 8 sets of covers, depending on whether or not you split the material. So, anyone who wants to buy a sheet will probably have a lifetime supply of cover building material for $20, and it would only take three of us buying one sheet each to make the minimum order.  
 
Regal Plastics' Fort Worth facility isn't that far from where I work, so if anyone would like to buy a sheet of coroplast, I don't mind paying and picking it up. So, I'll ask the question: If I make a trip to Regal Plastics, who wants to buy a sheet of 4mm black coroplast for $20 (I'll have to make sure that price is still good)?

I do! I do! I'll take one(Peggy doesn't think she would use hers. We could always share).

I'm in for a sheet.

A wheelcover making party...  I love it....    Count me in!

I'd be glad to swap someone for just enough to get the rear wheel done on my Corsa by getting all the heavier duty type coroplast you need for projects like tailboxes etc.   DJ

Are you saying you have a source for heavier coroplast? Alright, come clean!

Why Bud, how astute you are!  Yes, that's exactly what I'm saying.  I'd guess it's heavier than what you're talking about using on the wheels.  Maybe I should bring some out to the Goatneck for perusal/distribution?

Yes, bring a piece to Goatneck. Because I split it, thicker might work ok. I'd like to see what a piece looks like after I split it.
