I agree where are the posts and tutorials or links to them, lots of guys are looking for your repair section and there is someone selling whole recievers I just don't know who but i have seem them
The problem with a tutorial on my end is liability if someone messes up and hurts themselves I could be sued. My option is to only outline dimensions for all the cuts and then it is on the builder. The complete receivers you have seen are prototype only at this point I know the guy who built them personally. He and I have worked on various aspects of this platform together for over 3 years.
