Z8 Posted December 4, 2003 Share Posted December 4, 2003 The issue I have heard of with the IR lamps is uneven heating. If you can imagine a large part, say like a hood, (the thoughts crossed my mind-no rock chips!?) you end up with an area cured, then you have to move the lamp a few inches and cure again. This results in "lines" where along the edge of the heat lamps range it cured but wasn't quite hot enough and then you moved the lamp again. Thats why I want a large oven, my idea of a stripped out chest freezer would work, but a tank of some kind would be great too. even if it's thin metal you can insulate around the outside with rigid insulation to retain the heat. You can buy a thermo that takes a surface temp to check for proper temps. Quote Link to comment Share on other sites More sharing options...
Metallicar Posted December 5, 2003 Share Posted December 5, 2003 Building a large oven is not much of a big deal, really. Take a look at the one in your kitchen and scale it up. 18 gauge sheetmetal, fiberglass batt insulation and some elements. The door hardware is very basic. You can figure the number of elements needed based on scale. Control could be as easy as a trip to your local appliance parts dealer. I figure I could build a 4' x 4' x 8' oven for less than $400. Sheet metal interior 2x4 metal studs from Home De-blow 3 -1/2" fiberglass insulation Foil faced! Sheet metal skin ( Maybe corragated for strength) Fire Rated Metal Door from Home De-blow or make a bigger door out of metal and wheel big racks of stuff in there. Do not put a locking door knob on this equipment. (damn kids) Hi Temp Silicone caulk for interior seams On the inside of the box, mount 4 broiler elements and control them all with a oven thermostat and a contactor. (Johnstone Supply) Connecting the power to the elements will require some care so the power connections are concealed and safe. Don't forget a light! I guess the problem for most would be getting the power from the panel to the box, or even having a panel large enough to feed it.

Z8 Posted December 5, 2003 Share Posted December 5, 2003 Building an oven was my first thought, but after pricing things out and thinking about the time involved, I started looking at a pre-built "box" of some kind that would work. I have not used an IR lamp personally, the lines issue is what I heard was a probelm with them. Some IR lamps available are quite large and for the most part lines wouldn't be a problem, but they are very expensive. Quote Link to comment Share on other sites More sharing options...
Owen Posted December 6, 2003 Share Posted December 6, 2003 Read somewhere on the internet today, maybe it was at Caswell Plating, about parabolic heat reflecting IR lamps that are tall and can "shine" down on the hoods. Maybe lines come from getting the lamp too close? Owen Quote Link to comment Share on other sites More sharing options...
Guest nikko74z Posted December 6, 2003 Share Posted December 6, 2003 Guys, powdercoating is hard work. I wish it were easy. When properly done, paint stripper will not remove the coating. I have been coating automotive,marine,aviation,bike frames, and a list of other stuff for the last to years. I have messed up several pieces and nothe short of 300 psi blast with sugar sand has removed it. For those of you coating stuff with excellent results, my compliments to you. I wish I would have had someone kick me in the a$$ when I even considered doing my own. Now I own SureShot PowderCoating and I enjoy it, but the frustrations I have gone through I don't wish on anyone. The IR curing system basically is a great marketing ploy. It does work, but not as one would hope for on a stand. Typically the lamps are used in a much different set-up. I can point anyone here in the right direction if they want to follow through with it and develop a profitable business. Just so you will know, folks that own Z's automatically get 20% off Later.
