Intro: Low-temp Resin/RTV Curing Oven
This will show you how to make a simple low-temp resin/RTV curing oven from a spare ice chest and lamp with a flexing arm so that you can cure your resins under ideal conditions no matter how bad the weather is.
You will need:
1 Large Ice Chest.
1 Lamp with a flexing arm.
Small amount of strong adhesive (I used some spare epoxy)
Magic Sculpt self-hardening epoxy clay or other filler material.
*A Dremel is HIGHLY recommended!*
Step 1: Remove the Drain Plug
The first step is to remove the drain plug. You won't need this when you're not storing liquids in here, and it makes a convenient place to run your power wire.
I've checked on a few different coolers and they all seem to just unscrew, doing this can be as easy as jamming an oversize flat head screw driver in and twisting.
Step 2: Route the Wires
The easiest way to do this is to simply use a Dremel with a sanding attachment to widen the drain just enough for the plug to fit through.
If you don't have a dremel, you'll either need to do this the slow way... or if you have a soldering iron you can try desoldering the wires from the lamp, running them through the drain, and reattaching.
Step 3: Prepare the Base
the Polyethylene used inside coolers doesn't exactly make for a good surface to adhere to, in fact few adhesives probably even can.
Determine where you want the base located inside the oven and make a mark around the base.
Take your Dremel or sand paper and scar the PE liner, and do the same on the bottom of the lamp base. Don't be afraid to get aggressive, the uglier it is the better the surface is for your epoxy.
Step 4: Mount Lamp Heater
Turn ice chest on its side/back/top/etc. so that the lamp freely sits on the spot you have chosen without falling.
Prepare your epoxy or other adhesive.
Apply adhesive to both surfaces.
Place lamp and let the adhesive set.
Step 5: Seal Drain Hole
Prepare your magic sculpt or other filler material and press fill the drain being sure that it does not simply exit the other side.
Let your filler material set.
