+====== Painting - Powder Coating ======
+The work involved in powder coating is about 90% Prep. ((mct496 of the XLFORUM http://xlforum.net/forums/showthread.php?t=1617845&page=2)) \\
+It's good to bake parts before powder coating at a higher temp than you would powder coat at to bake the impurities out of it. \\
+Also you can flash heat the parts with a propane torch to clear any moisture that may have been attracted to the cleaned part. ((simeli of the XLFORUM http://xlforum.net/forums/showthread.php?t=1617845&page=2)) \\
+And preheat any tight areas and drop the powder on the gun as you coat to make sure that it gets coverage there as well. \\
 ====== Ovens Used ======
+You can use a gutted and steel lined upright freezer for an oven. ((flippindakgb of the XLFORUM http://xlforum.net/forums/showthread.php?t=1617845&page=2)) \\

 <blockquote>I allowed it to stay hot for 45 minutes before shutting it down 2 hours later it was still 180 degrees inside the box.</blockquote>
-  * 108 sq. ft. of insulation
+  * 220V, 108 sq. ft. of rock wool insulation, 33 cu.ft
   * 20 gauge steel for the heat box faced with cement board
   * 4 inches of space packed with 70 sq.ft. of insulation
   * The door face is 20 gauge steel (as is the surroundings) with 1-1/2" of space with 30 sq.ft. of insulation packed into it.
   * 1/4" gasket on the surroundings.
+  * Metal studs
 Door latches were not installed in the pics below but jack straps were used in their absence. \\
 Total cost: about $497 (not counting the door latches) \\
+The heat is supplied from the bottom and one side causing a natural air rotation inside the box. \\
+In testing, ther was around 10 degree difference in the temp of the rails (rack supports). \\
+(which is actually less than the temp rise and fall between heating cycles) \\
+The only "glue" that is used is 3M "77". \\
+(on the outside of the inner box (steel) and the inside of the outer box (plywood) which is cover with aluminum foil) \\
+The gasket is attached using RTV red and was cooked out during testing. \\
+The cement board is attached by pop rivets and bolts. It was also cooked out during testing. \\
+The oven is also used to gas out the parts during the cleaning process, so everything is gassed out before any coating is done. \\
+Flash heating with propane gets the metal hot enough so that any moisture is evaporated. \\
+Also any lint or dust that may be present is burned off. \\
+Powder is applied quickly after flashing or in the case of larger pieces flashing continues ahead of the powder. \\
+In use is a regular household style oven controller. \\
+But there are four of the internal oven thermometers that will be mounted inside. \\
+Plus an external probe thermometer that goes through the door (noticed in the pictures below). \\
+It should be about 30-35 minutes of actual time to watch the work and manually control.
