Humidity Proof DT

[1911KY]

Humidity has been in the 70 to 80% range a lot lately. I have DT'd about 400 casts lately with no coverage issues. Here is a video of my process in hopes that it will help others with their swirling issues.

My theory is that swirling this way creates a greater static charge and doesn't allow the PC to settle at the bottom of the bowl.

Every PC bowl that I have, has a lot of extra powder in it. I can swirl bullets without adding powder to my bowls and get good coverage. Here is the result from the video:

Good informative video, thanks.

That is what I do now, after having problem holding it against my vibrator tumbler. Thanks for the video.

1911KY, going to try that. Thanks.

Thanks!

Just make sure you press in firmly on the lid...it ain't pretty when it breaks lose! If the first shake doesn't coat well, do it a second time and it should cover them really well.

I use some screw on lidded #5 containers I found at the store--so far no pixie dust in the air
.
I've tumbled them while is was pouring down rain. I was under a shelter in front of the garage and had no problems.
.
For me humidity hasn't been an issue

Humidity has been NO problem since I have been doing mine in a vibratory brass tumbler that I was no longer using. Lyman's Turbo with their smallest bowl. Sometimes the powder gets too think on them and does the little puddle around the bases, but reducing the powder paint content in the bowl helped that. Good video, thanks!

I did the swirl swirl both sideways and flat and of course the shack a few times. Humidity was 70% so you tell good or not.





EDIT that didn't work worth a hoot.

Good video! I noticed the color was just almost black looking. Anybody else have good luck using a tumbling method using this color?

Gloss blacks will tumble very well, even for me on a good day. (I just don't have "the touch" usually)
I believe that matte black resists all tumbling efforts though.

Beagle333 I have tried several different Matte Black MFG and so far have not found one that will tumble coat.. Gloss (jet) black tumbles just fine
I think most of the reported hi humity tumble problems stem either from not shaking hard enough, wrong containers, wrong BB's or old bullets that have developed a surface oxidation/contamination (may not be visable with the naked eye) clean those in acetone and that problem seems to go away

Shacking hard enough was my problem. Humidity was in the 70 yesterday and I got perfict coating by shacking the dickens out of the container. 200 of those boolits had been cast last year but keep in a sealed container. So happy now I could sing, probably a good thing you can't hear over the internet.

[Smoke4320]

Great to hear 62chevy .. you are on your way now ...

The matting agent in the flat powders kills the minute amount of static we generate in the bowls. Just like graphite or moly kills static!

If you want black boolits you will either have to use some of Smoke's great gloss black or get an ESPC gun for matte finish powders. They go on great with ESPC!

I did pretty much the same thing as the original poster, last night... my first powder coating experience ever. I was powder coating 38/357 hollow points and 40S&W hollow points from Erik Ohlen's modified Lee 2 cavity molds, using Harbor Freight Red, black airsoft bb's, and the same kind of plastic container the OP used. Worked great!

Our humidity here has been pretty high, in fact we've been having flooding in this area, rain every danged day, and the driveway got partially washed out Thursday night. Friday night... tumble coating with no trouble.

So you guys in high humidity areas, don't be afraid to give it a try. I live 6 miles from the Mississippi river, 2 creeks join at the corner of the property about 60 yards from where I was powder coating last night, the skeeters are big enough to scare the birds, and we've got way too much humidity - But this method still worked for me, as a first timer newbie to doing Powder coating in the first place.

I also had more bb's and more bullets in the container, and did bigger batches than the original poster did in his demo. Maybe 100 40S&W or 150 38/357 at a time. Worked fine.

I did notice my bullets on top were coated better than those still in the bottom of the container for some reason, but that's easily corrected with a really quick re-swirl and shake after picking out all those on top that were very well covered with powder.
There is no reason I can see to be bashful about giving this a try, gentlemen.

yes You hit the nail on the head if not coated well close the top and shake some more .. It will get there

I have two kinds of black from Prismatic Powders, Satin and Ink Black. Both tumble quite well and give great coverage. Lately, I have been mixing the two 50/50 and it is still glossy just doesn't look as wet. I measure the number of boolits and the amount of powder I put in the bowl to get a repeatable thickness. Great results

[Dragonheart]

I think you will find if you stay with high gloss solid colors you and get a good one coat coverage. I personally use my modified tumbler to coat three to four hundred pistol bullets at a time. Then cook three batches at the same time.

yes the gloss black and blue you sent me to replace the flat black works great. Still not sure why that flat black will not work !!! also 100% on the cleaning. I drop my from mold to water to quench, then shake and bake. If I let them set for a little while I will use automotive paint pre cleaner, as some of them will not take the powder. I think it may be from oil on my fingers, but I just let all mine soak in pre cleaner now then air dry or towel dry if I am in a hurry. I have not had any issue with them since no matter what the weather.
