I need to cobble together small "hot box" for transfer paper
Itsa Little CrOoked:
I've searched and searched. I am only doing 12x12 at this point so it doesn't need to be huge.
I tried a heating pad but it doesn't have enough heat (wattage) and I'm really struggling with paper stability.
The 2nd pass might be off 15 or 20 thousandths or more....but that's just a guess. I haven't really measured. I'm trying to do my 1st trip down the tunnel at the same temp and dwell as the first gelling pass.
Anybody have a good one they care to share the design details for?
Thanks!
Stan

Woah! Are we making cocaine here!? ;D
Itsa Little CrOoked:
Nope, Alex. No cocaine use in my eclectic collection of hobbies!
My mind....although similarly twisted....went directly to Barbequeing in the Dark! I have a Weber Smokey Mountain at my shop. The back opens up to the alley and I often can be found with a couple of Chuckies, some Ribeyes, or a pair of Butts in pone of the various stages of YUM! I smoke Ribeyes first in Apple chips for about an a quarter @ 200, then sear them at the end in butter on the hottest skillet I can muster. "Reverse sear" is the term.
See, I even hijack my own threads. ???
Moosey, I was more thinking a styrofoam insulated plastic bin from Office Depot with a silicone pad heater in the bottom. But Thanks!
I can NOT find the perfect heating element. I don't want a huge thing. My workspace is starting to look like one of those Hoarders on A&E.
140 Watts of heating pad from Walgreen's is just not enough. I really googled hard, but no joy.
http://www.speedwaymotors.com/Moroso-23996-External-Self-Adhesive-Heating-Pad-5-x-7-Inch-400-Watt,32140.html This shows a 400 watter for under the oilpan Minnesotan in January kind of thinking. That's too many shekels for an experiment, plus it's pretty tiny. Mike's idea would provide more even heating, by far.
I wondered also, if a dimmer switch and Nichrome wire might work. Or maybe just some Nichrome wire and a lot of math. The math is a bit of problem for me. I used to build heated motorcycle jackets and gloves, but I didn't do much of the math myself. I shamessly stole most of it from the interwebs, and modified it for my needs. (They did work, very well indeed! The gloves were bullet proof. The jackets were fragile. I tried some pants too, but they were too hot and you could see red skin on my legs after a long ride in the low single digits.)
Somebody, somewhere.... has done this already.
Itsa Little CrOoked:
Nope. A dimmer switch and Nichrome wire is not safe. http://jacobs-online.biz/power_supply_design.htm
But I don't really want to do that much work anyhow, unless there isn't another way.
