I'd like to do my launch build on a couple of dual deploy rockets a couple of weeks before launch because of some personal timing issues (obviously I'll do the engine build on site). I am mildly concerned about the following and am looking for some ideas to solve the concern. Specifically, I typically handle my dual deploy charges as follows. I connect the Quest Q2G2. I put it firmly into the bottom of the ejection charge well and then pour in the computed amount of 4f black powder. I then fill any remaining space with a flame retardant insulation and cover with metallic HVAC tape. I've used this process for many years and so far (fingers crossed) never had a deployment failure.
My concern is that I'd imagine it is at least possible that the tape could loosen after a week or two in which case either before or during launch the black powder might migrate out of the ejection charge well. I've thought of maybe using a glue gun on the edges of the metallic tape once on or perhaps a fastener of some sort around the tape (a plastic pull tie for example). Anyway, looking for something that will reduce the chances of this potential point of failure. Thanks.
