Tinder Rocketry FAQ

It is VERY important to follow the directions for the device in question. In most cases, you will be instructed to fill the Powder Measure Vial (PMV) "to the line" with BP or one of the listed BP substitutes ONLY. The volume of the PMV when "filled to the line" is .2cc. Yes, you read that right .2cc. It is a very small qty of BP or BP substitute. I do NOT offer a weight for this volume because the weight varies depending which pyro powder you use. Do not weigh the pyro powder, use the volume measure!
In the cases of the line cutters, the PMV is offered as a convenient way of filling the cutting piston cavity. The cavity on the cutter is the measuring device! It takes a very small qty of the approved pyro powder to fill the cavity. And again, I do NOT offer a weight for this volume because the weight varies depending which pyro powder you use. Do not weigh the pyro powder, use the volume of the cavity as the measure!
