This corning dust isnt realy dusty it like very fine grit... Very nice to work with much better than balled milled Meal..I have decided to make more Pucks from it and then what ever is left from that will save for Priming etc...I have made this New Batch of BP specifically for Lift so i made a fairly large batch to eliminate small batch to batch constistancy. it took well over a week and im still not finshed!
.I milled each component on ther own for 2 hours using a 50% media 25% charge.I then dumped all 3 components into the Barrel and left it milling for 5 hours.. i did 2 batches a day for 5 days..Even tho i had pre milled the chemicals first i was surprised to see how much they expanded after further milling..
Before and
After..
Once all the milling was complete i combined all the green meal in to one big batch and mixed it all together to make 1 big homogenous mass.. i then split in into smaller batches and added 10% water (with 5% alcohol added). following the same procedure as on passfire, i began to press the pucks using my 4"
Powder Die .
Notice the hose clamps are a bit grotty? thats because they kept snapping? i decided to aneal them with a welding torch to hopefully soften the metal so they wouldnt snap..the white discoloration is the zinc coating that burnt off.. I loaded the Aluminium Disc in to the Die then added about 170 grams of BP then added another Aluminium disc and repeated this 4 times..
After applying about 8 tons pressure and waiting about 10 mins i noticed water began seeping from the Powder Die.also after 10 minutes you could see the pressure had dropped so i increased the pressure waited 10 mins . then increased pressure again ..total time in press was 30 mins..
...When i split the powder die i wiped up the excess water with a towel and the Pucks fell apart easily...
Pucks ..
..I let them dry for a few days before i started to corn them , i used an old 6" PVC milling jar to crush the pucks in .A Big Steel bar which weighed about 30 lbs was used to smash the pucks(I know you shouldnt use steel because it can spark but as there is no metal in the PVC tube or the BP it should be a very small risk of sparks?

).
Pucks to Be Bashed..
, the heavy iron bar made short work of the pucks
Bashed..I screened the contents in to 4 to 10 mesh for 2FA & 10 to 20 mesh for 3FA.. It didnt take long at all to corn the BP... After all this hard work i was rewared with....
2FA 7 1/2 lbs
3FA 5 1/2 lbs
Corning Dust 6 1/2lbs which is about to recorned ..
..........All in all im very happy with the resulting BP it's very labour intensive but once i see my 8" willow shell break in the sky

i Know its going to be worth it

... i will post some videos of the BP burning later with side by side commercial BP as a comparison..
