"Trying is the first step toward failure." I had three failed projects tonight, all involving my ergo.
First, I planned to solder the fan blades to the spokes to eliminate any twisting. It turns out that solder is pretty flexible, and has crappy tensile strength.

My next project was to remedy an issue I was having with the rubber pads sliding off the feet of the ergo because the manufacturer used some really crappy adhesive to hold them on. I bought a metal drill bit and some metal screws, and was planning to screw the pads to the feet (can't tell if that sounds dirty or not. I kinda don't think so).

Well, the feet pivot around on a ball structure (ok, now
that sounds dirty), so I was only able to drill in about 1/16 of an inch before I hit said ball, and no screws exist that are short enough.
My fater-in-law does auto upholstery, and had some industrial-strength contact adhesive, and this seems to have done the trick. Time will tell.
My final task was to add some weights to the wheel of the ergo to add some standing start resistance. The ergo's builder told me to use adhesive wheel weights (like they use for cars), but I couldn't find any at the auto parts store (apparently they only sell the adhesive ones at tire stores). I purchased some regular clip-on wheel weights, hoping they would work. They don't.

That didn't stop me from hammering on 36 of them and taping them to the rim to see the affect of the added weight.

I can definitely feel a difference, but this particular technique of adding weights will not work. I only had to add one pound, so I may just try putting a heavy tire and tube on the wheel.
Are you starting to pick up on the fact that I have a touch of OCD?
