Advise on building a CNC table

[Robin Hewitt]

If someone asks for advice on their new idea and everyone says, "Don't do it" you might think that would count for something. After years on forums I can assure you it does not.
Confidence is that feeling you get just before you understand the problem. Brimming with confidence the beginner assumes the forum has got stuck in it's ways, isn't prepared to accept brilliant new ideas and needs to be led from the darkness into the light of a new age.
After rejecting all advice he tries to build something. People will still try and help because they know that after a couple of spectacular failures he will become a useful member and willing to shoulder the burden of answering beginner questions.
I think the best introduction to CNC would be...
1: Buy someone else's failure cheap.
2: Identify where they went wrong and fix it.
3: Use your new found skills and the fixed machine to make something better.
I don't think anyone will ever take this advice but there is something delicious about saying, "Told you so" (You would think that somewhere we would have a tongue poking smiley but I cannot find it, please use your imaginations)
