Powder Coating with Harbor Freight gun PIC HEAVY

[7oaks]

Awhile back I purchased a powder coating outfit from Harbor Freight. Today I used it for the first time. I'd like to share with you all some of the learning experiences I encountered. I should have started with a test piece but being my usual impatient self my first objects were a pair of dogs for one of my Contras. I should know better as I made mistakes that forced me to redo them once. :taped:

I took pictures through the whole process and apologize for the lousy quality of some of them. I was using the point and shooter.

The whole setup. Note my high tech paint booth.

The ground wire attached to the top copper wires which support the dogs.

I did two at a time hoping to save on powder and I think it did but you have to use extreme caution when moving one that you don't touch the other because the powder is indeed only powder until it is baked. You can blow it off with a cough or touch to anything.

Note the plastic bucket on the gun. One comes with the kit. Buy more. The powder at HF comes in three colors. White, black and red and in plastic containers that look like they can be used on the gun. THEY CAN'T!!!!! Don't make the mistake I did and attach it to the gun. In my case it fell off dumping a good portion of the red powder. Get one for every color you want to use regularly so you don't have cross contamination and don't have to clean them up before every use.

This shows the old toaster oven I am using. This is where I made my first mistakes. I coated the dogs on both sides. When I went to move them from the booth to the oven I knocked off powder in several locations. Then when I got to the oven I had no choice but to lay the dogs down flat on the grill. Wrong thing to do but I couldn't think of another way with this small oven. Big mistake because it knocked off more powder expecially where the grill touched the dog. Grrrrrrrrrrrrr

Please forgive the glare and dirty glass on the oven. Those marks on the dog are on the glass.

Here is one of the dogs after coating. I am showing the good side. I will resand the back side and recoat/bake! The red perfectly matches the Contra/Lightning red.

-----

Please use protective masks. You can see here how much I would have inhaled had I not had the mask on.

-----

After I was all done I came up with a better way to bake items like this. I screwed a stainless steel screw through the top of the oven and then placed it on its side. Now I can/could hang the dogs from the screw. Live and learn. But the dogs came out quite respectable I think. I really like the HF powder coating system and will be using it alot in the future.

Thanks for posting that. I've been considering buying one, and this is very helpful.

Oaks! YOUR THE MAN!!!!!!!!!!

I have been talking to another member about this exact thing! THANKS! for the pics and opinion!!!!

I am glad it is working out! I will admit, I didn't think it was even worth it!

What about doing case halves? Do you think it would work?


AGAIN THANKS!!!!!!!!!!!!!!!

 

[tomdcoker]

Yes, Thanks for posting. I have been looking at one and any knowledge you give is more than I had. Thanks again. Tom

I'm glad that some of you are finding this helpful. I enjoyed doing it and now wish I had more to do. By the way the spilt powder cleans up easily with compressed air - just don't get it wet before cleanup. I reclaimed the powder on the floor of the booth - don't know if that is a NO NO but thought it couldn't hurt.

Everything depends on the size of your oven. I can place a case half in this oven - on the rack if it isn't too big. I have a spare Contra one I probably will try on it. I have one more of the plastic reservoirs but will be purchasing more. I bought some gray that looks like it will mimic the old Contra gray. The hard part will be removing the old paint since I don't have a sand blaster setup.

 

[Teddy.Scout]

I just got the HF sand blast cabinet, had the neighbor do some modifications to the seals and glove attachment points. I still think that when if EVER I get to that point of the cases, I will have to take it to a place that has the high power(psi) and a bit heavier aggregate? will see.

Thanks again OAKS!!!!

And as always! YOUR THE MAN!!!!!!!!!!

You just pissed MY wife off when she saw that screw thru the oven.

 

[jimdad07]

If you don't mind me asking, how much does this setup run?

Tell her I'm sorry but those things are a dime a dozen in yard sales and Good Will. LOL

$70 normal, on sale right now for $60 and with 20% off coupon that would come to $48. Not a bad price don't you think!

I'm really not shilling for HF. I'm just happy!

If you have a spot in the shop, and a 220 outlet, a good investment would be an old electric stove with a working oven. If you wanna use the stove in the house, well, if you think the wife got mad from you using the dishwasher for cleaning saws......

Yeah, I've thought about that. Actually have an old gas oven in the shack down the hill. The instructions with the kit say don't use a gas oven but another member here who has access to commercial powder coating equip told me that they use large gas ovens. Who's going to try it first? :biggrinbounce2:

 

[Arrowhead]

Nice job!! I've been thinking of trying a powder coater.

 

[redunshee]

Great info. I saw that Eastwood carries numerous colors for powdercoating. Might be a source if you need colors other than what's available at HF.

Nice thread Carl! That finish looks great.

Just a thought - if you have an old kitchen oven you can use, why not cut the top out (lose the broiler element) and make a hanging plate that you can use to coat the parts then set it right down into the top of the oven?

Yes I've seen that also. I did find/purchase some new colors on eBay - ones that match the items I'll likely be powdering. Now I need some more of those plastic cups.

Great idea! Quite doable! I'll have to think about cutting up the old gas range down at the shack - you know the one I mean.

Hey just a little tip that may help hold the powder on the parts when removing from the powder coating booth is to preheat the parts to be coated in the oven first then the heat will help the powder to stick to the parts resulting in less being knocked or blown off when returning to the oven for baking.

You mean the servant's quarters?

Thanks for putting this together and posting it, got me thinking strongly about going this route on my future rebuilds.
