The puck is dried and broken into chunks and then run through a centered Hario coffee grinder. The screens are wire cloth from Mcmaster. The first screen is 30, the lower screen is 50. So far it is...

I just made a decision. I will use the hydraulic meter on my press only as an indication of more pressure rather than a true measure of compression. Then I will increase pressure until The bp can be...

That is what I use. Clever use of packaging material for a tool.

What type of screen do you use? Mcmaster has many different types and I have had the feeling at times that I was using a type that wasn't optimum for black powder.

I was thinking about balling the green meal and then grating them before loading them into the compression die. Will try that if nothing else works.

It is incredibly fine. I use 13 lbs of 3/4 ID copper pipe 1 inch long filled with lead, throw everything in without pregrinding for 24 yours. It is fine enough that it looks as if it has some of the...

I hadn't thought of using no water but that deserves a test. I've two pounds of green meal so I can do a lot of testing.

Interesting. I live in Houston and it is consistently humid here so I will try that too.
One test I am going to run is to put an oz in a ziplock baggie, add water, smush it up and let it sit for a...

I am using Fly's 2" die and compressing to supposedly 1800 psi. The Hario has been adjusted to be centered but still nothing useful. I use 1 oz batches which produces nice 1/4 " pucks.

I have a lot of failures when grinding, I am getting dust when run through a Hario grinder and I am not completely sure why. Willow mix with 2% dextrin (out of frustration) is yielding powder. Dried...

Hi everyone. I'm back after several years hiatus. Real life kept me off the board. So Howdy to all!!!

Fence boards of western cedar work very well.

Much superior to ball grinding media. I use 2 lbs of dry mix and 14 lbs of grinders. Works fine. I generally grind for 24 hours and the meal sort of looks like a liquid when I open up the barrel....

This is the way to do it. I started using the same type of grinding media last year and it grinds quickly and much finer than balls. Produces exceptional green meal.

Babbit is one possibility I hadn't considered. It froze up in the mold in under two seconds. I'll bet that is the answer. Thanks.

I let the pot sit for maybe 2 hours at 700 degress during dinner and when I came back afterwards there was a skin on top which was bright blue, very different than the normal blue of pure lead. I...

I took every bit of zinc out that I could and it appears to be linotype. Probably trade in on some pure lead. Man, that is hard.

I do have zinc but have taken as much from it as floated to the surface. Not too worried about that but I will test for it.

Friend gave me 200 lbs of lead from his dad and I figured that it was ml type as well as coww lead. I put about about 10 lbs in some bhn 10-12 bhn and after the first cast I had to use a rubber...

There is a saying from the revolutionary war period: muskets 200 yards, rifles over 200 yards.

I used play caps for a while but it destroyed the pistol. EXTREMELY CORROSIVE. Like pouring acid on your gun.

The hand crank. By the way, 1" gas pipe fits perfectly in the handle slot. It is way easier to crank.

Does anyone know the diameter of the hydraulic plunger for the harbor freight 12 ton press?

Sally Beauty Supply is a good source for end papers.

I weigh my boolits after they cool down. +- .5 grn.
