I have reason for doing in this way. If you see 8 plate series cell link, I did exactly like you said. When the pressure increase (over pressure), leakage can happen from vinyl sheet because no support at centre of the cell. Also, you need to find suitable size nylon tube to seal place where threaded bolt goes through. Experience from 8 plate series cell, I made changes in 13 plate series cell to drill holes on each plates and vinyl sheet.
Yes, its time consuming process but worth in the end. I use three diffrent drill bits to make single hole onto SS plate. Now I can tighten the nuts more to make no gas or electrolyte leak from drilled hole. No matter how much pressure builds up inside electrolyser casing, no electrolyte leakage will happen from vinyl sheet electrolyte seal . Another advantage is I can reduce electrolyser size a bit.

No matter what, safety comes first. Use softdrink bottle (coke bottle) as safety bubbler. Do not use hard plastic. You check some exploded bubbler made from hard plastic in 8 plate series cell link. If you want to use homemade flashback arrestor (like you are using right now), make it after softdrink bubbler.
You need to use longer bronze fine wool container. This could be the cause of explosion happens where the fire by passed your homemade flashback arrestor. You know what, when I first tested hydroxy torch, I wear full face helmet as precausion. My hands were shivering to during torch lighting.

After that enjoy the success.
