Definately good post by Tiki. I learned all these things from experience and seeing others mess up.

Thanks and cheers.

Tomorrow I will ask my LBS to use their space to take some pics… Definitely I’m going to make a tutorial teaching how to assemblie and keep the uni in shape!
Now I know what’s the first Tech Article of my website!!!
