This didn't start off with the goal of getting an inexpensive Cerakote setup... it just sort of happened. So, I thought I would share it in case there are other home DIY'ers that are interested in having the capability.
I bought this 20 gallon air compressor in the spring because I needed a new one. I bought it with the intention of just using it to blow away chips when machining.

It was on sale at Home Depot for $140 (and is again right now!). It came with the hose, an impact wrench and a ratchet.
I started to get the urge to want to sand blast some of the parts I was machining to remove the tool marks. I had access to a blasting cabinet at the last place I worked, but didn't anymore. I ended up getting a small cabinet from Princess Auto while it was on sale for $125. It leaked a little around the door, but a bit of weather stripping fixed that problem. The compressor seems to keep up with it ok for what I'm doing. I added a fitting to attache the shop vac to it to clear the dust.

Then I got thinking that it would be nice to blast barrels in it. The only problem was that it was only about 20" wide. So, I came up with a way to get a longer barrel in it... well, half a longer barrel in it (then I flip it around).

A rubber plug I got at a pool place keeps the tube from filling up when I'm not using it. It can also be removed.
The next problem that came up was water sometimes building up in the hose and getting fired through the sand blaster. Air gets heated when it gets compressed and when it cools, the water comes out. So, I created piping system to cool the air and trap the water, and installed a filter/dryer to remove any water or moisture that got through it. I got the filter/dryer at Princess Auto for $100.

Nice dry air after that!
Well, I have a couple of actions I am building up and four barrels for them that need to get coated. Actions cost $150 each to Cerakote and barrels are $100 each... which adds up pretty quickly. Since I already had the compressor and the blasting cabinet, all I needed was the spray gun and Princess Auto had those on sale for $18. Sweet!
Unfortunately, my plan to use the oven in the kitchen to bake the parts got nixed by the wife... after I had the Cerakote in hand!
So, I had to find an alternative way of baking them. Fortunately, I read online that people use things like toaster ovens and meat smokers for this purpose. A toaster oven is too small, but I found this smoker at Cabelas on sale for $200:

It has digital temperature control (read PID), a timer and an internal height of +26". I can can even fit a 32" barrel in there diagonaly. Going to make a jig for that...
I painted an 18" Kidd 10/22 barrel tonight as a test run. It turned out great!

It wasn't till after that I realized how little it cost me for my setup.
$140 Compressor
$125 Blasting cabinet
$100 Filter/dryer
$200 Smoking oven
$18 Paint gun
$75 for pipes/fittings/etc...
$658 total (+tax) for all the tooling needed to sand blast parts/barrels and cerakote them. Yeah, I got everything when it was on sale, but these items seem to go on sale pretty regularly. The compressor is on sale right now, and so it the smoking oven. It can obviously be done for even cheaper if you don't want to do full length barrel (toaster ovens are $30 new), and if you already have some things like the compressor.
