  2. Hey Guys, I wonder if you could help me out here. I have searched in my country for 70 lb kraft paper but without luck. That stuff is somehow impossible to come by. I came across this site: http://www.rajapack.nl/webapp/wcs/stores/s...tegory_rn=13136 It's kinda expensive, but since I don't understand a word could you help me out on how much shipping one, two or three of those rolls would cost to ship to Denmark? Or even better, anyone know where to get similar paper cheaper?

    Nitrocellulose

    If we are thinking of trhe same "thinner", it's the stuff used to thin cellulose lacquer (nitrocellulose lacquer with some resins in it) which contains acetone, toluene and ispropanol. It would work, but I would think that just pure acetone would be better? Not sure of how toluene dissolves NC.

    Cut Star Loaf Box

    Hi, it's generally a box where damp composition is rammed in using the square rammer in increments. The box is then turned upside down so you have a loaf of star composition, which you slice like bread. You then cut each slice of "bread" like you normally cut stars :D

    Cut Star Loaf Box

    I made a loaf box, inspired by the one on Passfire. It consist of a box, roughly 80x120x100mm, and is smaller at the bottom in order to get the star loaf out. Also a rammer with a handle from an awl and a block of wood filled with lead in each side to make it heavier (I covered the lead with some white coloured filler). I havn't tried it out yet, though. But I think it will work just fine, even though the scrap wood I used is crooked by being in the humid garage It was treated with some kitchen table oil so the wood won't get ruined. Here are some pics, with some recycled kraft on the walls of the box in order of easy removal of the star loaf.

    First homemade rocketĀ“s!

    If the outerpart of the charcoal is crumbly and soft and the inner part uncarbonized you might need smaller pieces of wood. How big are your sticks and your cooler roughly?
