If I had a customer call me and tell me 5 out of 5 parts I made for him failed, I would send him 5 new ones the day he told me and I would pay him to send the old ones back so I could see where the problem was.
In this case sounds like a picture would have been enough for them to see the goof. There is so much mark up in stuff nowadays they could send him 5 for free and still make money.
i do completely agree 100%. i am just curious how much difference there is between his and mine.
i didnt mean to respond straight to you it was a impulse.
interesting story just now. i am getting ready to shoot some powder. i used my gun 2 days ago. No power on anything yet. i clean my hoppers after each use. opened a hopper to wipe it out before i poured in the powder the can had enough electrical charge to shock me.
Is it getting dry where you are? More static charge in winter. Hopper plastic?
not really rained the day i sprayed.
Ther is your answer (rain) the dampness is a great conductor. when I was younger, I cut cedar shake bolts out west have a helicopter come in on weekend to fly out the slings of cedar bolts. helicopter had a 300-foot-long cable with hook and big diameter steel ring around attached to end of cable. never grab ring in rain until it hits a sapling tree, or you will get a shock of your life. The rotor blades create a lot more static electricity in rain, and you become the conductor, ask me how I know. Dam that hurt…
Bolts as in threaded fasteners?
Here is a picture of the cans, the same pic I sent them. The can on the right is the one with the gasket leak, I fixed that leak during color changeout.
Yeah mine does look like those they definitely changed them.
All my fittings are hot glued in.
@GaltsGarage I make universal hopper kits, and the top portion from this kit would be a good solution for your leaking problem. Let me know what you think, I would be happy to sell just the top portion if you are interested. I also make kits that will plug directly into the gun. Feel free to email or DM me with any questions.
I just placed a order. Will give it a shot.
@Phillipw I appreciate the order, feel free to reach out with any questions once the kit arrives.
No, cut cedar log to 24" lengths, split rounds into manageable size stack on a length of rope that has an eye spliced at each end get weight to around 1200pounds so a Huey 500 helicopter can lift sling of cedar bolts and fly to logging road and dump.
I’ll message you as soon as I get done today, thank you!
If you get a chance show some pics of how you switch colors? do you just unplug the hose from your gun and blow it out then plug in a different one?
How much powder do they hold?
Are they vented? if not does this not cause a vacuum on the cans?
Have any trouble from clumping? as they have no fluidizing tube connected
I can post a video of color switching, shot one today. With my setup the idea is to shorten time between color changes which is why I bought 4 extra hoppers and 4 extra latex lines. For my setup I just have to disconnect the hose, pull out all the nozzle pieces and blow out the gun and the pieces. I wipe them down too real quick after blowing them out in the paint booth. If I’m changing colors in a hopper which I also did today, I blow out the hopper, the latex line from hopper to gun, and the air line to the hopper. I’ll try and get that video edited this weekend but I’m kind of buried trying to sort out these issues. The gold would not take to the gloss blue on the sign I was masking with the vinyl, I had to do my first ever hot flock and it worked beautifully. I’m about to go re-shoot the blue denim with the settings and nozzle recommended by Columbia. After that I have to cut out a backing plate for the corvette sign and throw a coat of gloss white on it. After that I will try and get that video edited. I’m starting to sense a trend with putting a second color down on top of gloss, so far it has failed 3 for 3.
i have noticed that some colors dont take a second coat as easy as others what kv did you try? i noticed that about 30 kv work pretty well then sometimes i have do 100 kv. when you try to hard you can get to much back ionization making it impossible to make powder to stick.
In their email Columbia recommended standard nozzle at 20-30k or wide mouth at 50k. I tried standard at 25K, same with second attempt, then I upped it to 50k on the third attempt. Then I stuck it in the oven, heated it to 250, put on the wide mouth and cranked it to 100K. That last one laid down beautiful, the bigger issue at that point was entirely too much vinyl masking. I’ll be spending the next week getting the remainder of the detail edges vinyl off and the adhesive. I think vinyl will work awesome to mask logos and lettering but for masking 2+ square feet on each side you just can’t peel it fast enough and as it cools it becomes harder, not necessarily brittle but it doesn’t have the elasticity you need to week it AND it leaves a TON of adhesive behind.
one thing to try use the second coat nozzle the wide one turn kv to 30ish. you may have charged your part to much. you can blow off what powder is on it warming it in the oven will discharge the part then start over. there is a big learning curve to powder coating. i think it is awesome that you dove straight into some of the harder and hard on your nerves side that quick.
Thanks for the suggestion and kind words Phil! Just finished for the day, got everything on my to do list for the day done-ish…Honestly it seemed like such an easy innocuous list when I made it, what the hell happened. So mostly good news on the day, worked 3 projects and had outcomes that I will describe on a scale of WTF to 10.
First, the Army Aviation sign (the sign with the vinyl masking) scored a solid OMFG but it can be saved.
Second the Space Force sign in blue denim scored 5 (public facing side is beautiful back side is yikes)
Third the Corvette sign in Red with White background scored a solid 8.
So, I did figure some things out and unfortunately the only way to figure some things out is to fail and fail and fail until you find something that works. Luckily, everything that I have really failed hard on has been free signs for friends. I like that model for learning because it’s free and your friends are gonna call you on it anyways…lol So, tomorrow is video editing day and I will fix the Army Aviation sign this week to the extent it’s possible. I think I will use a heat gun to soften the vinyl then slowly pick it away, then probably toluene or xylene to remove the adhesive left behind by the vinyl, then I might shoot a coat of clear on to shine it back up. We shall see. Thanks again to everyone for their help and encouragement on this lunacy so far.
