If making HTMF-12 E-Matches with the MF-KIT what should they look like?







When I make e-matches with the MF-KIT the grayish colored pyrogen is cracking as it dries.
This can happen, especially in very warm and dry climates, when the pyrogen is to thick. Add more MEK thinner to the pyrogen until it is thinned to the proper consistency. ie. The pyrogen should quickly run off the end of the wooden stir stick when removed. We have updated the MF-KIT instructions dated 11-26-13 or later to reflect this change.

I've lost the instructions for dipping matches, can I get a new copy?
YES. The instruction sheet is available for download here in Rich Text Format (.rtf.)

How long is the shelf life of your pyrogen once its mixed?
Several years. However, never attempt to re-wet dried pyrogen. Store in the airtight container the pyrogen came in to prevent the pyrogen from drying out.

Once mixed does the CF, MF or ML-KIT require a LEUP?
No.

Do I need an ATF manufacturers permit to make my own igniters?
No. A manufacturing license is not required to manufacture low explosive materials for one's own use.

How do I fold the igniter wires before dipping for larger motors?
Click here for a pdf document on folding options, and here are some cross-section diagrams of folded and dipped matches:
 

A dipped match with no folds A dipped match folded once
A dipped match with 2 folds A dipped match with 3 folds

 

Why do you recommend using only the longer MF-24 or MF-48 igniter wires with your CF-KIT, what about the shorter MF-12?
Clustered flights add a whole new challenge to the successful launching of a rocket. In order to improve the chances that all of the rocket motors will be ignited by the time the rocket leaves the launch rod we recommend using the longer igniter wires to keep the igniters in the rocket motors for a longer period of time before they are yanked out as the rocket travels up the launch rod. This is especially critical if your rocket is using a combination of BP and AP propellant based motors.

I have made several e-matches using the MF pyrogen kit and when I test fire them all I get is a loud pop and partial burn of the pyrogen.
What did I do wrong?

Because of the extremely fast burn rate of the MagFire e-match pyrogen it becomes necessary to partially confine the e-match in order for it to function properly. For test firing purposes you need to place the finished e-match inside a two (2) inch long piece of 1/4 inch inside diameter polyethylene tubing prior to test firing it. (see picture)

Which altimeters WILL work with MF ematches?
Any altimeter that can supply 1.6A or more for several tenths of a second should fire MF ematches.
NOTE: Ground testing is strongly recommended.

Devices that have been tested to successfully work with MF ematches:
1)  G-Wiz LCX Flight Computer in 2 battery (high output configuration)
2)  Perfectflite Hi-Alt 45K altimeter
3)  Perfectflite MT3G Timer

Which altimeters WILL NOT work with MF ematches?
Capacitive discharge (CD) altimeters, such as the Perfectflite MAWD, will not reliably fire MF ematches.
While the MAWD is capable of several amps of output, it will only do so for a few hundredths of a second.

Do you have the Tripoli Motor Thrust Curves for your entire rocket motor line?
Yes. Click here.
