Just two points in response.
One, in today's climate regarding vapes/vaping we all need to be aware of exactly what we're using.
Two, I'd love independent testing of food grade silicone exposed to vaporizer type heat. And that vapor that passes by inhaled. Self testing is a little shaky.
Still though thanks to HR for responding.
I agree, and think most here are, but HR has already gone 'the extra mile' to assure us they're taking care of business........
When it comes to safety testing, it's like we used to say in the Dynamite business, 'some's good, but more's better'. At this point I honestly see no need to question, 'everything fits', but perhaps you should do so if you're not comfortable. You have randomly selected seals why not send one off? You really don't know what temperature to test at, but again, a higher than realistic temperature should 'prove' no problem at lower temperature? I think the instrument you're looking for is a "gas chromatograph":

I vaguely recall driving one back when I was paid to do such things, they've no doubt become easier to use with computers and such. Fairly common gear, in certain circles. The very thing to sniff out not too many molecules of gas mixed into the inert 'carrier gas' stream.
Yes, thanks to HR, too bad he has to keep repeating himself, times how many forums? IMO he earns his money.....and provides a few jobs for folks no doubt glad to have them? IMO that makes him a good guy (white hat), tired perhaps, but the sort we could use more of?
Removal of the screen for dumping or stirring is done easily enough with a safety pin.
Love it JC, if I follow. This should increase the diameter, therefore the area? Especially if you use woven mesh (which air passes through easier than holes through a flat plate) Bet that kicks the draw restriction down the road big time. You can I'm sure 'out draw' it even easier, but for use through a WT (where there's added restriction anyway) I'm guessing it's worth the effort? And with more screen area it's going to foul more slowly? Longer between cleanings, again cool.
You know there's a gadget called a 'sheet metal punch' that is used to make holes in sheet metal by punching them (clever name), this one might do the trick to make a pile of 'em really easy:

If I'm following where you're putting the screen it measures about .42 on my F2 (most handy), HR says they use the same gasket so the size must be the same. This means the 13/32 at .40 or 15/32 at 4.67 are worth trying. The punched out bit automatically comes out slightly 'crowned' since there's a blunt pin on the punch to keep the roach from hanging up on the way through the die (makes the punched out part slip through easier). If not, the 7/16 one in this set:
https://www.amazon.com/Eastwood-Met...eway&sprefix=sheet+metal+punch,aps,614&sr=8-7
could be the call? You can set the stop and quickly punch out a row of 'em from a sheet or strip of mesh. The are useful for making washers out of strange materials as well. That one saved me a time or two over the years. You can easily punch the big hole first, hammer the dimple out, stick it to a piece of tape to control it, change dies and punch the hole. If you leave a bit of the dimple you can use the dent against the pin in the center of the second punch.
Sorry to ramble, but I think you may have something good happening.
BTW, if you heat your safety pin 'glowing hot' at the tip (with a small torch) you can quickly grab it with pliers and bend it over to make a hook while it's still soft.......
"Good on ya" as they say down where it's Spring time.
Regards to all.
