Swede Posted June 8, 2008 Posted June 8, 2008 My granulated BP from grapevine charcoal..I think that is fast for lift uses.Your opinion? Looks pretty quick, pipipi! The initial glow made me think "wow, it's just smoldering" and then WHOOMP. How much was there? And can you improve the focus at all? Looks good, though.
psyco_1322 Posted June 9, 2008 Posted June 9, 2008 lol, I should have known that after looking at a munch of willow names trying to figure out if htere was any local black willow. Guess I didnt pay much attention to what I was reading.
Yankie Posted June 9, 2008 Posted June 9, 2008 I also have made eucalyptus BP several times. It grows crazy in CA where I am originally from and everyone in my region uses it as fire wood since it makes horrible tasting barbecue. I believe it's the "blue gum" euc, but anyways it is always a slower burning powder for me at least. I love it for charcoal stars because like AqwA said it is very bright and leaves decently long hanging embers.I might have found a new source of charcoal for stars, in comparison to pine is it better or worse?PS. does it make any difference if you use the pine cone, pine wood or pine bark?
Bonny Posted June 9, 2008 Posted June 9, 2008 PS. does it make any difference if you use the pine cone, pine wood or pine bark? From what I understand, the wood is best to use. Strip the bark and don't bother with teh cones.
Yankie Posted June 9, 2008 Posted June 9, 2008 I have only ever used the pine cone and the bark, makes for nice charcoal streamers though and the meal powder is good for fuse and priming. My next project is Pawlonia bp and blue gum charcoal streamers, will post how they go.
Swede Posted June 9, 2008 Posted June 9, 2008 it was about 1-2gr.. Well, from what I could see on the video, it went off with a nice WHUMP rather than a slower burn, so it looks like you've got some good BP. Congrats!

deadman Posted June 9, 2008 Posted June 9, 2008 Now I've never used yellow pine. But from what I've heard it is a much different type of burn. Pine is supposed to be bright, long lasting, and branching/sparking. You won't get the branching/sparking from eucalyptus (or atleast I haven't). It's more of a smoldering. The reason I mention yellow pine, is because I have used lumber grade white pine which made a decently fast BP.
Jwilson Posted June 23, 2008 Posted June 23, 2008 Here is my first ball milled bp. This was 1g balsa charcoal bp milled for 8.25 hours. What is everyone's opinion on it? Thanks Note it burned completely, its just the newspaper burning at the end there.
mike_au Posted June 23, 2008 Posted June 23, 2008 Looks pretty reasonable to me, certainly better than my first batch and probably pretty close to my more recent ones. Was that granulated or straight out of the mill? Have a look at making some blackmatch if you are after some quick and easy fuse (although you probably don't want to waste balsa powder on it).
Jwilson Posted June 23, 2008 Posted June 23, 2008 It was straight out of the mill. Ill try granulating some other time if what I currently have is acceptable. Balsa charcoal is some fluffy stuff! A small 250ml sour cream container full only weighs about 10g.
Flying dutchman Posted July 10, 2008 Posted July 10, 2008 Hello here is my black powderhttp://fr.youtube.com/watch?v=0Ot-Mosy-3cI know,it's slow,but i'm a beginner and i don't have a ball mill,and the charcoal is for barbecue.
oskarchem Posted July 10, 2008 Posted July 10, 2008 Actually granulating it would make good enough lift. you would have to do about 1/6th of the shell weight I think.
Flying dutchman Posted July 11, 2008 Posted July 11, 2008 No,for lift i use H3 powder.But is it fast enough for a shell burst ?
nath0r Posted July 11, 2008 Posted July 11, 2008 Im not sure if that would be fast enough for burst, try granulating it and testing the speed again. You could try making a small shell with just burst to let off on the ground and see how it performs.
Richtee Posted July 11, 2008 Posted July 11, 2008 Just messing around, trying out sending a movie to Youtube...I THINK it worked... anyway- 2 grams of my newpaper charcoal BP, ballmilled 3 hours, pressed and corned to what I use for lift... maybe 15 mesh or so BP Test
nath0r Posted July 11, 2008 Posted July 11, 2008 Woah, thats powerful BP, if you can keep making consistent batches like that using newspaper, you will save a fortune on charcoal. Nice one!
Richtee Posted July 11, 2008 Posted July 11, 2008 Woah, thats powerful BP, if you can keep making consistent batches like that using newspaper, you will save a fortune on charcoal. Nice one! Thanks- but I would still make my own charcoal. The N.P. has been the best so far tho. I have not tried balsa, but it's faster than the willow stuff I made about a month ago
Richtee Posted July 11, 2008 Posted July 11, 2008 Just messing around, trying out sending a movie to Youtube...I THINK it worked... anyway-Also was suggested by my mentor to do a 2 foot train test. This is dust left after corning, dampened and screened thru 20 mesh. BP test..powder train
TheSidewinder Posted July 27, 2008 Posted July 27, 2008 qwe ya bugger, get the filename right. It's an AVI, not a WMV. (Caught ya editing, lol.)
TheSidewinder Posted July 27, 2008 Posted July 27, 2008 OK, the AVI filetype wasn't defined, nor was allowed to be used. It SHOULD work correctly now. EDIT: It DOES work now. AVI has been added as allowed filetype so this error shouldn't occur again.
qwezxc12 Posted July 27, 2008 Posted July 27, 2008 (edited) I got around to testing some of the Red Gum bound Red Alder BP I made a few weeks ago this morning. Regular 75:15:10 made with Red Alder charcoal milled ~6 hours in my mill in a 1200g batch. It's bound with 3% Red Gum (milled in), not pressed & corned, just wet with alcohol, consolidated into a patty and screened through -14 mesh screen. Burn trough is the "standard" test, I suppose: 3' trough, 2.5' of BP (30g), as outlined on Danny Cregan's Charcoal Test page Burn time was 14 frames at 30fps = .467 sec. Pretty good stuff. Picture and video attached. This is the stuff that nuked my 3in mortar lifting a heavy starmine on the 5th... Seeing as my 6in shells are lifted with 1/16 their weight in CMC bound BP, which is slower, not sure I want to use this stuff on big shells, probably just for 3" and under shells and comets.

TheSidewinder Posted July 27, 2008 Posted July 27, 2008 Ok, I think I know what's happening here. Let me go make an adjustment in the Admin Panel. Defined file types can be touchy, I see. EDIT: Ok, I guess I DON'T know why it's insisting that that was an AVI File. The MIME-type was correct. I'll have to research this more. Wont happen today, but it WILL get fixed.
nickle Posted August 2, 2008 Posted August 2, 2008 (edited) I just finished reading this entire thread,all 41 pages, and wish to thank everyone for the knowledge that has been imparted. I guess it is now time to try and see if any of it has sunk in. I have all my chems. and have for some time, so I guess its time to head off to my "Mad Scientist lab" and see if I can put the knowledge to work. I again thank all of you who have helped educate me.
