I didn't bother with blind rivets as I had plenty of the normal kind laying around plus, I think if it starts blowing gases through the rivets then it's a sign that you need to re-pack anyway!

I wrapped the entire package of wadding with aluminium tape - there are several benefits to this;

You can 'form' the correct shape for the can, making it easier to insert.

Slides in easier as there is no wadding to snag on the sleeve

Adds an extra layer of heat protection to the carbon once the wadding has burnt out.

Termignoni only use a couple of wraps of paper masking tape but I suspect this is to keep the cost and assembly time down rather than best practice.

If there is not already some in there use some SS gauze around the perforated tube before wrapping the wadding as this helps protect it (Termis have this, not sure about others?).
