you mount the igniter where you want it and take the two leads and fasten them to 2 screws.

drill 2 holes where you want on the chamber and mount the screws/bolts the the holes with the leads connected.

make sure there is at least a 1" gap (around there) between the 2 screws/bolts for optimum performance.

and if you want, put epoxy around screws/bolts to make the seal air-tight.

hope i helped

This is one of those "if you can't figure it out on your own, you probably shouldn't be doing it" questions.

My igniter is mounted directly inside my chamber and protrudes about 2" in to ensure the best possible ignition. A quality igniter should have a screw fittting to lock it into place.
If u choose to use this method however, i would recommend using sufficient amounts of epoxy resin both inside and out and additional silicone sealant inside.
BigBob12345 is 100% right in saying igniters are NOT pressure rated, and i would not recommend this method unless you are ABSOLUTELY certain a pressure seal can be achieved.
Ergonomics was my decisive factor.

Pipe caps do tend to come apart when u put igniters in them.

Do not mount the ignitor in the chamber they are not pressure rated and can blow out causing hot gases to go all over your hands causing bad burns...[/quote]
