CoreSeverin Posted March 28, 2021 Share Posted March 28, 2021 Hey everyone! This is my first post, I've been lurking for a few weeks and I have been working on learning to hand tie jigs. I have a question about painting, specifically poor quality painting. is there a way to rework bad paint? I had some sags and runs after curing my powder coat, I am going to adjust my heat down to 200 for the next run, but is there a way I can rework the ones that turned out bad? 1 Quote Link to comment Share on other sites More sharing options...
Michigander Posted March 28, 2021 Share Posted March 28, 2021 If there's a way to (reasonably) remove powder coating from jig heads, I want to know too! 1 Quote Link to comment Share on other sites More sharing options...
CoreSeverin Posted March 28, 2021 Author Share Posted March 28, 2021 @Michigander hey there! Im thinking about sanding them just to get the shape right, not sure if it will be the best method, but it should work more or less. m going to drop my curing temp down from 350 to 200, and add some more time to it. that should keep it from happening again. mainly I just want to salvage the work I already have.

I don't know how you are painting them but you are getting too much paint on, it isn't the curing temp. The next thing is 200 degrees won't cure those jig, you need about 225 and at that temp they would need to cure for 1.5 hours. If you aren't using a fluid bed you may want to go that route as you will get a thinner more even coat. If you are using a fluid bed then you are holding the jig in the powder too long or you are getting the jig too hot. The last thing is your curing oven, if you are using a toaster oven you'll need to check the temp with an oven thermometer. Toaster ovens, even when brand new, are often off 10 degree or more than what the dial setting is. I had an over that when set at 325 was perfect for curing as the oven thermometer was reading 354 degrees, 29 degrees difference. 2 Quote Link to comment Share on other sites More sharing options...

Most all ovens that don't have a built-in thermometer controlled dial are like this, our old propane oven is off by almost 15f, my wife's baking successes really improved once we started using a BBQ probe to monitor temps.

cadman Posted March 28, 2021 Share Posted March 28, 2021 If you want to remove bad powder paint job quickly, put all your bad jigs in a glass bowl, and pour paint stripper over all of them. Wait 15-30 minutes then wipe off. next wash them under water let dry and repaint. Make sure you use a old bowl that you don't eat with, and wear rubber gloves as the paint stripper is acidic. That is the quickest way I found to remove painte without sanding and filing. 2 1 Quote Link to comment Share on other sites More sharing options...
Super User Jig Man Posted March 28, 2021 Super User Share Posted March 28, 2021 Smalljaw knows what he is talking about so take his advice on curing and Cadman told you how to clean them. These two guys are the pros around here. Back when I would get those runs and drips I just used side cutters or gate shears and cut them off. Then I would mat them shiny with clear fingernail polish. I have not had a run in many years. I heat the heads with a heat gun one at a time. I do the old 1 1000, 2 1000 count to get the heads heated the way that I want them. I want them hot enough for the paint to stick but cool enough to have a dull finish. I tap the hook on the side of the fluid bed cup to remove any excess powder. Then I cure them. My oven is a $2 garage sale toaster oven. Trial and error has shown me that 15 minutes at 350° is what works best. 2 Quote Link to comment Share on other sites More sharing options...

I don't have a fluid bed, I am sure that I can find plans for building one pretty easily. I am probably getting them too hot as well, I am going to try to reduce my time over the heat gun and see if that will reduce the amount of paint im putting on them. I had a feeling I was painting them too heavy, but I thought it might pan out in the end. Quote Link to comment Share on other sites More sharing options...

Yeah this will work really well for me. it would really be a shame to just have a box full of botched jigs that just sat there wasted for years, thanks for the tip, really helpful. 2 hours ago, Jig Man said: Smalljaw knows what he is talking about so take his advice on curing and Cadman told you how to clean them.

I just started making jigs, and I haven't got everything dialed in just yet. I'm glad everyone was willing to take the time to walk me through some of this stuff.
