I just saw a video on moistre levels when mixing concrete and It got me thinking about pressing pucks. The tests that were done on the concrete that was mixed so dry it would barely form, was nearly...

I also posted some results about pressing pucks dry. I'm in Florida and we have humidity. If it gets below 70%, it's a good day. Below 50% is almost unheard of and only happens if we have a cold...

Doublebuck - I was the one who posted about crushing pucks with PVC. I just use a 2" cap and a 1 1/2" cap. I don't have them mounted in pipes or anything. I put my pucks in the 2" cap, put the 1 1/2"...

Vettepilot - My die set is very similar to your picture. Of course I don't have the set screws, but I also don't have the step on the bottom puck, either. For me, it works better without the step....

I have a short puck that goes in the bottom of my sleve. I put the puck in the bottom of the sleeve, fill it with powder, put the main piston in top of that, then press it. Powder can't get out that...

The alcohol/red gum thing got me thinking... there would be no way to control this and it would go away over time, but... what if you had a little alcohol residue in your black powder when loading...

Well... I did some experiments. Here are the results..

1) The fun one - I loaded some .45acp with black powder and shot them from my full-size 45 (G21) and my subcompact 45 (G36). They worked and...

Indian Joe - Vette Pilot is right in a sense and you are right in a sense. If someone is looking to make their first batch, any materials you can get your hands on will make something that goes...

Doublebuck - true words.

As far as a binder slowing burn rate... if you were to use only 1% ot so, I'm not imagining that it would make a huge difference. I gave some 38 sp and 357 mag rounds to a...

As far as dwell time... I've noticed that it seems when my pucks are done, they are done. I'll put the initial squeeze on them and the pressure will back off within a couple of minutes. Then it will...

Speaking of speculation.. I've been speculating that binder might be beneficial after all... if just a little water does something to "activate" the ingredients and make them bind better, maybe just...

I was in Harbor Freight today and I looked at the 12 ton press to see if they had changed the design at all. Yes they did. My top member is two pieces that sendwich the side members a lot like the...

On another note, I re-pressed that dry powder after wetting it and letting it sit out. It did just like I'm used to.

I've used vacuum to dry things in a mason jar. At room temp, almost nothing happened. When I hit it with a hair dryer (from outside the jar) it boiled rapidly as soon as the temp rose only a couple...

That's a nice group. And there's nothing wrong with safety, but this is not the most dangerous thing I do by any means. I've tried to light part of a puck before. I set it on a paper towel and lit...

I did an experiment today trying to press some dried powder. All I can say is that you all must live in the desert! I dried the powder on the dashboard of a car. It was completely dry. I tried to...

I've tested my powder for density. My 3F is slightly larger than GOEX 3F and it comes out 12% lighter than GOEX for the same volume. I can get 25 grains of GOEX in an old .45acp case and 22 grains of...

The way I press my pucks, I get two at a time. I have about 3/4" of height in my 2" die. I'll press one and almost immediately push it through into a shorter die that I made. That gets put back on...

I'm in Florida and, while we do get humidity (a lot), it's nothing like what a couple spritzes of water would be. I'm goung to dry my next batch if fines on the dash of the car. That gets hot enough...

My fines go right back into the press just as they are. I think my powder is getting more and more dense with each trip through the press. I plan to do some calculations to make sure, but I am...

I'm not sure why it isn't working for you guys. Maybe I'm pressing harder? I'm using a HF 12 ton press. My jack went bad, so I replaced it with a HF 12 ton jack. I press the powder, putting a good...

You guys might try pressing pucks dry. I've never used water and, thus, never had to dry pucks.

I have granulated a couple of batches when I first made powder. It burns MUCH faster than greenmeal. Enough so that when I showed the difference to a friend's mom, she said "Oh, WOW!" - And she's 78...

I had concerns, too, about my media coming apart. I had to finally decide to just make powder because nobody else has reported a vortex in the space-time continuum. My first couple of batches seemed...

The fit isn't really good enough for a puck die set. It flexes some under a good ammount of pressure, too. You could possibly cut out some of the grinding, but I just grind for one grade - 3F....
