Introduction: Go-llerblades: Motorized Skates - Part 2
This instructable is an addendum to the previous one, and documents a lot of improvements I made to the original project.
Step 1: Add a Switch in Line
I sliced one of the power cables and put a switch in the middle.
Now I can turn the gollerblades on and off.
Step 2: Replace the Wire Brush With a Urethane Wheel
I got this wheel from my local hardware store (they have *everything*).
First, I drilled out the center of the wheel to make it fit over the threads of the angle grinder.
I also bought an angle grinder nut to hold it on - they're a little pricy. I could alternatively have salvaged the nut from the wire brush.
The wheel had a curvature that prevented any threads from being exposed above it, so I flattened it a bit with a hammer.
Also, I noticed that if the wheel wasn't pressing against ground, it tended to stretch and fly off the wheel quite a bit.
As you can see, the urethane deforms a lot.
Fortunately, this wasn't a problem.
Step 3: Use Bicycle Innertube for Lashing
Last time I used duct tape. Not a flexible or reusable material. If you want this project to be permanent, use something sturdy and reusable, like these handy strips of rubber (available free at every bike store)
Step 4: Film Yourself [video]
An have a rocking good time, whizzing around a parking lot with your friends.
The switch was definitely wonderful to have, the bike tubes quite convenient.
On the other hand, I learned that urethane grips less-well than a wire brush,. Also, with the actual wheel, I did not go as fast as I did with the wire brush. Possibly a bigger, heftier wheel would do the trick - or I'll just stick to the wire brush.
