However, from discussions, he does not appear to believe that distributed quality control and distributed fabrication is feasible, from my email communication. - MJ		Master prototyper down to 1 micron.

	#Part 8 - Enclosures. You can plug up defect holes with a spot welder. You can do knockouts with a waterjet. 2 Us for an enclosure. Captive hardware so fasteners don't fall out. Paint - 275C for 20 min. Powder coating hooks are not reusable as they get painted. Excsss powder cleans up with vaccuum. Tap on a drill retap nuts. Keyholes + slots - extends your life 1 year.		#Part 8 - Enclosures. You can plug up defect holes with a spot welder. You can do knockouts with a waterjet. 2 Us for an enclosure.

	#Part 9 - materials. Mild - gauge 10 + gauge 18. Gauge 12 + 18 in stainless. Series 300 stainless for springs, full hard or 3/4 hard. Stainless cut ends - http://www.sidecuts.com/.		#Part 9 - materials. Mild - gauge 10 + gauge 18. Gauge 12 + 18 in stainless. Series 300 stainless for springs, full hard or 3/4 hard.

	#Smooth surfaces - [https://makezine.com/2015/03/20/18-lessons-smart-prototyping-self-made-billionaire/]. Scraping and lapping. Hydrodynamic = zero friction, zero wear. Reversal method - with a dial indicator - to get straightness or flatness or runout of an object. Can separate roundness from runout. Reversal method is critical to precision and metrology.		#Smooth surfaces - [https://makezine.com/2015/03/20/18-lessons-smart-prototyping-self-made-billionaire/]. Scraping and lapping.

	#Strength vs stiffness - 2 bars held with rubber bands are stiffer then a single one as long as the 2 bars don't separate. [https://www.youtube.com/watch?v=MtxA20Q-Uss]. Clamping vs set screw - we use this on the heavy tractors:). Design 101 - think of wire first. CNC wire bender. Second - sheet metal. Multi-disc clutch. Then go to solid. Design of machine vs instrument. Design for disassembly. Hydraulics/water below electrical. Does not apply to air. If is 100% functional, it is always beautiful.		#Strength vs stiffness - 2 bars held with rubber bands are stiffer then a single one as long as the 2 bars don't separate.
