Ive used those sparkers for my minis but quit using them because the break easily. But they do work well, yours is built cleanly, good job, whats size cannon do you plan on using it on?

You mean 3 inchs long 4 inch diameter chamber, It will be a pain to ignite a chamber that large without a fan and you might should just use a bbq ignitor
