sorry for the back to back, but my wee hour vaping brought me to this next mod:
Using the VG screen catch loop, and a ss screen. I just had to expand the loop a bit so it would take a snug fit, got it snug down at the bottom of the taper, and put the screen on top of that. Easy mod, works well, just go light handed on the torch, much easier to over do it, but so far I have not combusted, and getting amazing hits! With this set up, you do have to be mindful not to press down too hard, so you don't pop your support loop down into the body. It can take some resistance for stirring and loading.
This seems to be working great like this, and I also found that the ELB cap was working better for that mod, but each has worked and has been fun experimenting with. The main concept here is that you want at least a few mm or so of an air gap between the load and the under side of the heat stone. So there you have it, 2 ways to use the HS for flowers. And I bet you could put some hash or kif in there too.
...oh and yes, you can use yellow flame, you just have to be extra careful not to touch it to the stone... we have a winner!!
Here's the ABV from my first load. I did stir a few times every few hits. looks nice and evenly toasted with no scorching. You do have to be careful stirring, not to move the screen out of place. At least while it's all fresh and clean.
