Yes I build them, i'm building a couple now for some members here. I haven't been updating the thread I started, but have been taking pics through the whole process, its just a matter of taking the time to download everything and post it up.
The guage faces are easy to make, my friend made mine from a picture of the actual face, then he cleaned everything up on his pc, then send the file out to be printed.
Yeah the one I posted a pic of is a P.O.S, totally unusable (especially if you're trying to do a quality build). There have been alot of them sold, but most people dont end up using them.
