In Topic: Titanium powder

07 October 2013 - 02:12 PM

can someone suggest a use for the ti I have? it was not free :o  it is 0-100# with only a few percent 100# most of it is very fine dust and im finding it very difficult to find a composition that uses it, other than adding it to stars and prime.

 

what I really want is to find a star comp that uses a high percentage hopefully giving me dense fine firedust tails but i'll be happy with any info on any comps, glitter,gerbs, ti brocades, anything. I started a thread on apc but have only a few responses, the best idea so far is to bind the fine powder and use it as larger mesh, there must be a way to utilise fine ti, im sure its beauty is waiting for me to find it :wub:

 

sorry for the hijack, it is almost destiny though, ive been searching all over the interwebs the last fortnight [ should have come here first]

well ive seen them firing pyrotechnic rockets, not much weight at all really, reciver and ematch can weigh less than a few ounces.
The reason i posted was i saw a fairly large cat going for a ride on one last night ( rudetube )
fps russia ( youtube ) had a play with an advanced one that is equipped with sub machine gun and 100 round magazine fully functioning.

Commended on your thoughts but i think you need to see some :working: quadrotors and understand your field before you try to challenge the experts in theirs.

In Topic: Straw charcoal samples

i never bought any, but it would most likely be fully cooked yes, not that brown just a tint and when milled it is black the proof is on apc oldguy designed and built a retort for controlling temps, the result was brown (ish) charcoal, plenty of pics i just couldn't catch the colour on my camera.

thats why its called cocoa powder, it is brownish in colour.
Properly cooked charcoal should not be completely black anyway and will be far superior to overcooked.
My retort is an open topped 10 inch drum, the flame does not jet out of the large hole, the second it is below the rim remove and cover, this yields the best charcoal( for me ) but it needs full attention, if a retort with small hole/s was used the gasses would still be jetting out at this time, aswell as being too hot inside.
The maltese make charcoal in open topped barrels from grasses and brush then cover the barrel in plaster when the charcoal is glowing and the flame has stopped, lots of ash.
Cocoa bp is said to be less powerful than ours due to its specific uses.
Temparature controlled cooking of reactive charcoals will give a better product. And be more sensitive than overcooked charcoal, my brown charcoal will take fire quicker than black charcoal from the same wood the same goes for bp made with it.
Im quite interested to see how this turns out, be safe.

See edit in last post.

is this due to the si that lines the edges of grasses like saw blades, why they cut you aswell.
It wont burn off at charcoal cooking temps.

Edit, im willing to bet on it, after some quick searching it seems that some straw and grasses can have as much as 20 percent silica/silicon as dried product, after cooking this will obviously increase.
Who fancys milling bp with 30 plus percent si ? Not me.
Id want to know exactly what straw it is and research the si yields acordingly, and then still not mill it.
