Supplies: 12” X 12’ 24g sheet metal roll (roofing material, Home Depot $10) Heat Gun (Harbor Freight $9) Aluminum Foil (Dollar Store $1) Scrap Wood (Free) to support the heat gun off the ground 2 small nuts and bolts (from the “junk drawer”, free) Optional oven thermometer (Harbor Freight $5) Cut your sheet metal around 76” long and roll into a 24” diameter cylinder. Drill or cut a hole big enough for the nose of the heat gun to fit about a ½” off the bottom edge of the sheet metal. Drill two holes and bolt the cylinder together. Cut a piece of scrap sheet metal long enough to span the cylinder (I used my Harbor Freight bead roller to stiffen the sheet metal lid). On a concrete floor lay out enough aluminum foil so the cylinder will fit on top. Place the cylinder on the foil. Put inside your oven your rim or other object to bake. If you have the oven thermometer go ahead and pop that in also. On top of the cylinder place your lid. Use more aluminum foil to seal off the gaps on either side of the lid. Put some metal weights on the lid and foil to hold it in place. You want your rim or other object to be supported off the floor of the oven and out of the “blast” of the heat gun. I used some sheet metal tabs used to connected 2X4’s in home construction. These were bent in an L shape and mounted to the rim with nuts and bolts through a few spoke holes. Once everything is sealed up put the nose of the heat gun in the hole, start your timer and turn the heat on high. Baking time per rim is one hour, the inside temp will get to around 350°. I would suggest doing a dry run to verify the temp you will reach in one hour, adjust your time if needed. NEVER NEVER NEVER let this thing out of your sight while it is running. Don’t have anything flammable near this, and make sure the cat is out of the garage (don’t ask).         |

I like it too, very cool and cheapo...350degrees is the correct temp for powder coat, i wish you would have done something that was more graphic in the pic....black or red satin, haha lookin' good...jeeps idea with a heat lamp would make it even cheaper if it would git up to 350...now ya got me thinkin take a saws-all to a top of metal drum...or even my trash can haha....but, how much for the powder coat gun and powder?

I’ve spent a total of ~$150. I’ve done two sets of rims and a bunch of smaller parts. I still have a lot of powder left. Bought 6 lbs, I may have used 2 lbs. I have a toaster oven for smaller parts (included in the $150 I spent). I did parts as large as the brake calipers, the triple trees and front hub in the toaster.  Raw Powder  Just starting to flow  The engine before rebuild  After rebuild (still need to put in the cam)  My powder coat "booth" I can spin the wire from the top to rotate the part  |

I am the Poster Boy for Harbor Freight! Just have to wait for the next coupon...
I'll have to start an HFA chapter, Harbor Freight Anonymous.
My name is Bob and it's been 25 days since I've been to Harbor Freight...
I bought the gun from HF, the powder from eBay. My brother-in-law bought some powder from HF and it was very lumpy, I'd steer away from what they sell.

JB,
I think you have started something. After reading this thread I have started to look into doing this myself. Locally, the powder guns are not readily obtainable but I did find Caswell Canada's distributor on the web and spoke with him today ( for the Canadian guys he is Jim MacMillan in Port Perry)
They also have a ton of interesting products including plating and anodizing equipment and supplies.
Before I order up does anyone have any experience with Caswell in general and their powder kit and paints?
Thanks guys,
Spyug.

I’m sure Harbor Freight can ship to Canada www.harborfreight.com Sign up for their email notices, they always send out discounts. I have heard good things about Caswell but have no personal experience with them. As with any “painting” project 99% of the work is prep. I have a HF blast cabinet that I bead blast everything in (after degreasing), and then all the surface imperfections are worked out starting with a file and ending with 400 grit sandpaper. I don’t think any part took more than 5 minutes to actually spray the powder on. Parts that go in the toaster oven (with a timer) are just set it and forget it. The rim oven is a little too experimental to run without watching it. I would have easily spent 3 times as much sending this out (but it did take many hours to do). I get a kick out of finding solutions to the problems that come up working on one of these bikes. The "chrome" powder I got off of eBay, not sure who produced the stuff. The cases and cylinder are just high temp rattle can. I would have powder coated them if I had purchased the powder coat equipment sooner (next project will be). Side covers are polished. If you want to polish a part do not use a bead blaster on it, the satin finish you get is very difficult to polish out. One final note on polishing, every part I’ve done needed some wet sanding to start with. I go - File, 220, 320, 400, 600, fine steel wool with soap, wash with hot water then buff. I have a buffing wheel to start with and finish by hand. None of this is difficult, just time consuming. |

Joeb,
The problem we face up here when buying from resellers in the US is the shipping/duties/broker fees which can easily add 70 to 100% to the cost. In the case of this pc gun, it may cost $70US but it will likely be about $25 for shipping, $14 taxes/duties at the border and if shipped by courier $40 brokerage= $155 US or $170 or so in Canuckbucks. The Caswell guys price is $140 CDn tax included. If shipped to me add $15. If I pick up (4 hour round trip)about $25 in gas.
He's located right in the heart of some pretty country ( Lake Scugog) so I might just take a run on Saturday. Take the wife and make a day of it.
Now if there were a Harbor Freight in Buffalo I might make a 40 minute dash to the border instead and grab one ( and some cheap brew) stop off at Hooters fer lunch, stuff it under my shirt and smile as I come across the border. Anything to declare sir? Nope just a good lunch ogling the girls! ;D
I just hope when I get one I can turn out the quality you are producing.
cheers,
Spyug
PS For the "oven" I was thinking the Old beer fridge is getting long in the tooth so if I wired in some heat lamps I should be able to get enough heat to cure things. We have a gas stove in the house so I couldn't use it. I had good luck last winter curing the paint on the frame and block just using Halogen spots so I think in an enclosed and insulated fridge I should be able to get things "toasty". think I'd have any problems?

Harbor Fright...........oh man. They have just 2 factory stores here in Jersey and the one is by my house. I spend a minimum of $200 every time I walk in for that $2.00 coupon I tell my self thats all I'm getting. My freaking garage is overflowing with sh@t because I can't fit anymore stuff in my two car garage. Harbor Freight is a VERY BAD, BAD place.
Great work on the powder coat parts & oven and excellent documentation, thanks for sharing.
