Well some lessons that have been learned on this build:

1) It always takes twice as long as you think it will to get it done and done right.
2) Design the Machine at least three times and expect to do more.
3) Ask for critical reviews of what you are doing and keep notes.
4) Write down what you plan on doing with the machine and over build by 20- 50% (trust me on that one)
5) Account for wiring pathways when designing (IF you don't, it will bite you).
6) Account for lubrication points (See above, only worse)
7) Account for maintenance work on the machine (being able to take it a part and put it accurately back together is important)
8) Plan for upgrades and what they will be and why (few of us can afford high end equipment from the very start).
9) Be willing to learn (that means knowing when you don't really know something and finding some one who does).
10) Remember these machines are wonderful tools that will seriously mess you up if not careful.

That is what I have learned so far from the First machine (a bought unit) and this build with JAZZ. I am currently seriously busy with clients work and business projects so might not be on much but will do as able and will try to keep folks up to date with how this build is performing.
