Not to rain on your parade, but this is not ventilation. I taught a friend of mine to make beads, lectured her on the importance of ventilation, and she ignored my warnings. She set her torch up just like yours. She wound up feeling sort of bad, ignored that too, finally had a check up at her doctor, he gave her a blood test and some other tests, she had carbon monoxide poisoning. He told her if she kept it up she would have further complications, now she has to get her lungs checked regularly. She did do some damage to herself. Don't fool around with your health. You need a hood to capture the noxious fumes created by your torch, and a good blower of some kind to pull them out. Period.
