    Default Hot Boxing with Corpsie

    I've been developing a way to make a device which could safely heat a firearm to 100F minimum and hopefully get near 200F.

    Requirements
    1. Lots of air space
    2. Don't take up lots of room when not in use
    3. Safe
    4. Electric heat only

    Status so far: I'm using 1.5" x 1.5" x 8' studs for the frame. For the walls I'm using heating duct material 5' tube that is ~26" in circumference. I unrolled the duct material and stretched it out on the frame using decking screws (#6 x 1"). This will make up the 4 walls, which are all made separately to be non-permenantly attached later.

    A 2' x 2' piece of wood will rest on the top of the walls with an eye-bolt hanging to suspend the firearms and parts. The eye bolt is attached loosely using large washers and 2 nuts to lock each other in place. This allows the eye-bolt to swivel.

    Heating: The heat source will be a 500W halogen shop light. My friend uses them to heat candle gel to ~300+ degrees F, so this should radiate enough heat to meet the box's temperature requirements.

    Anywho, that's the status so far. Hopefully I'll be testing it within a month. My first experiment will be to sweat the nasty cosmo out of a Yugo SKS.

    Sounds good so far. How are you going to regulate the heat?

    To regulate the heat I can:
    1. Move the light into or out of the box
    2. Allow more heat to escape from the top.

    Most likely I'll let hot air escape so that fumes don't build up.

    Use a dimmer switch for the regulator like those halogen torch lamps use. You can pick up a dimmer wall switch at home depot for a few bucks. If you have a modern digital volt meter like I do they take temp reading as well. Find out what temp is at different settings and mark your switch.

    Now I have a good idea on building a cosmo sweating oven which it much better than my kerosene heater and 6 inch duct work.

    BTW: Duct work is a great way to build something like this and you can do double wall, so the outside doesn't get too hot.

    I'm no expert in metallurgy or thermo dynamics, but it seems to me steel dissipates much more heat than candle gel....may need a larger heat source.

    It would be plenty to bake cosmo out of a wood stock. 140-160 degrees has worked well for me. I stick them in a bag wrapped in plastic and paper towels inside of my extra car during the summer. I won't have that extra car much longer, so a small oven would be nice.

    The ducting could get wrapped in insulation as well.

    Here's a good garage made coating oven for the guns

    The problem with that is that the heat gun generates around 750 deg F and that's not too safe to leave unmonitored for any period of time.

    Sounds like a good way to cure those specialty paints also. I picked up a used toaster oven cheap at a garage sale and I thought about cutting a hole in one end and then using duct work to lengthen it.

    Grendeljaeger,

    Curing speciality paints is my main motivation. If it works, I'll be able to apply lighter layers and have them dry and cure faster.
