烤箱……
建议先直接浇注好一批发动机，然后防潮保存。即使不出危险，这样烘来烘去的也会影响燃烧。

　Step 2:  Molding the grains
　　A bit of propellant has been heating in the toaster-oven at 200 degrees.  After 20 minutes or so, it is nicely soft..
　　DO NOT HEAT PROPELLANT IN A MICROWAVE OVEN!  It will ignite!
　　The propellant is recrystallized KN/sucrose to which 1 percent red iron oxide (Fe2O3) has been added.  This gives it a brick-red color, and increases its burn rate.  Kn/dextrose works too, and  does too, although it burns with a little less enthusiasm.
　　A small chunk of propellant is cut off, rolled into a slug, and pressed into the longer molding tube with a short stick.  A little more may be added while it is still hot.  The tube is filled to within about 1/8 inch of the top, and pressed down firmly.
　　

　　

　　

　　
不知是不是正确的....翻译过来是这样的
步骤2:成型的谷物
　　一点药被加热的toaster-oven 200℃。20分钟后,这是很柔和的. .
　　不要在微波炉热发射!它将点燃!
　　这个药是recrystallized KN /蔗糖,1%的红色氧化铁(Fe2O3)已经被增加。这给它一个brick-red颜色,并提高其燃烧速率。Kn /葡萄糖作品中,也有,尽管它燃烧和更少的热情。
　　一小块的推进剂流动被切断了,变成一个塞、滚压入不会管与短棍。多一点可能会增加时,它仍然是热的。管子被填在大约1 / 8英寸的顶部,压紧。

翻译的太糟糕了……

不建议加热……不是很安全……而且影响性能……

　Step 2:  Molding the grains
第二步：让燃料成型
　　A bit of propellant has been heating in the toaster-oven at 200 degrees.  After 20 minutes or so, it is nicely soft..
这一点推进剂被烤炉加热到了200度。20分钟之后，就变得很柔软了。　　
DO NOT HEAT PROPELLANT IN A MICROWAVE OVEN!  It will ignite!
不要在微波炉里面来，会着火的。

推进剂是KNSU重结晶，1%氧化铁粉末，砖红色，提高喷然比。KNDX也不错，也可以这样玩，但是烧起来没SU爽

一小段推进剂被切下，滚进嵌条，并且用一根短棍推进那个比较长的铸模管。

200度是华氏度吧。。。不然20分钟燃料都黑掉了
Step1是啥？重结晶？这个燃料貌似是做好了的
