It's the holes that keep it still. When you move your hands in the box the air can displace out the holes. In a glovebox there are no holes so the air just swishes around in the box. There is more ambient air movement in a glovebox than a still air box. Don't worry its not blind trust I understand why its better. And its definitely not foolproof, not even a flowhood is foolproof.
If it works for you then by all means keep doing it though.

I flame inside the GB with a small blow torch.
To create the best of both worlds. WHAT IF I cut a 3 inch circle hole in the side of my GB and stuff it with polly fill so the piston air is filtered at least?

If you're really worried about bringing in contams on your arms in an SAB you could get some tyvek sleeves. I just raw dog it, but some people use tyvek suits when doing their sterile work
Not sure how long you've been using a glovebox, you seem to be happy with it and it's your grows, so feel free. I just think you should be cautious working with an open flame in a closed, unventilated compartment that you sanitized w/ iso alcohol
I'm not quite sure, tbh, what tf the piston effect is. I was never great at Physics. But I believe the issue w/ gloveboxes is that the rubber creates air currents with the air already inside the box, so adding a filter wouldn't fix it because you're not trying to filter air coming in, you're trying to stop air currents from being created from air that is already inside

As Kernale said, it you get your work on spot and it works for you, it`s fine. But i won`t handle a torch in a box with iso around. I guess you just clean your tub with water and soap? But i need iso in between and i won`t risk building a bomb Also a flame inside forces air currents. If you get away with that i wouldn`t change anything.

Try to imagine a railroad tunnel, as a train rushes through. Open air, the air is moved to all directions except the ground. In the tunnel it quickly reaches the borders forcing enormous air currents. The piston effect is more complex of course, that`s just a little explanation. So the bigger the arm holes in the sab, the less piston effect you have. Also better for comfort, and not moving the sab from scratching narrow holes.

wipe down whole GB with iso then close lid
iso evaporates very quickly
enter arm holes/gloves a few mins after, flame S cutting tool with no issue while grain/agar lids closed.
cut agar insert to jars, iso wipe or flame, cutter between dishes
for G2G its a non issue. you just wiping everything down with iso no flame.

I don't find not having a nicely flat surface on the bottom of the SAB matters for putting agar into jars. But when pouring agar into plates it must be level so I turn the box over on the kitchen table or a card table.

Get you a better box and make a new one. 12$ and no more worries. But truth be told its pobably fine. Peoplework with a box that the whole front is cut out not just arm holes. Just be mindful of how you move and breath while you have open plates. When I first started I put some incense in the box and let it get Smokey then used old plates to practice my movements. It gave me a visual of how the air moves inside wich I found very helpful.

The lid isnt sealed. When you seal your arm holes moving around in there sucks air in through the lid

With a lighter, inside the box, right after a good spray with iso.

I couldn’t imagine having my hands restricted by taped gloves while I’m doing work, especially those thick yellow ones. I used them once when disposable gloves were all out and then went straight to bare hands lol.
The glove box seems like it could work and I guess it does for some but flaming inside is dangerous when there’s fumes and the heat will cause air currents, not to mention the force of gas coming out of the torch so any contaminant spores still inside (and there will be unless you fill the whole thing up, seal, and sterilize it somehow before starting work) will get all whipped up in a frenzy.
I think the SAB seems too low tech/simple for people sometimes. Like with folks who have to automate their monotubs with gadgets they just can’t believe something so easy will work best.

I think that's right on the money, people think its too simple. Technically speaking you could do work in open air as long as it's still. The box just prevents particles from your head or the ceiling from falling on the work.
I think people see laboratory grade equipment and think anything short of that couldn't possibly work. That's why you see beginners avoiding agar because they think they need a flowhood.
