Nice video. I agree with Rich, speak louder or towards the mic. In the write up can you include a list, vendor and price of parts? Where did you get the aluminum?
Yea, I know, I'll talk louder in my next video, still a little green at making video's

If you have read my last write up about the LED lights for beginners, you'll understand that I try to label or list everything and where to get it and I'll make sure I do it with this write up as well..!
The material... I talked to some local metal works guys and they gave me a couple of the scraps that they weren't going to use, they also lead me to
McMaster-Carr yet again, if the pieces somehow didn't work, I would have ordered it from them (suggest hitting up places for scrap though, gives ya an excuse to ride around anyways). Here is the link
McMaster-Carr, try to go with some 6061, unpolished if you can, won't be more than 15$ for the 1/4" & 15$ for the 1/8" (you can definitely find some 1/8" somewhere, don't even need 6061 for those)... There are other places too on the web, I'll make sure to list them all in the write up.
