Basically, the way q21q21 described how he did things sounded great, so I went ahead and put a 1g of crystals in 15ml of vinegar and have been trying the whole "boil off the vinegar and vape the goo in the machine" process but gosh it's awful. I've now just been trying to do crystals to eliminate a few variables, but it's still awful, so I figure I'm either burning the DMT or the choreboy is giving off vapors (i thoroughly pre-torched it though). It seems it a slight majority opinion on here that choreboy is good for use in the machine, but I'll probably try to seek out some thick steel mesh tomorrow and try that out. I get some small hits that are just like air, but when I go bigger I get some instant cough awful lung feeling hits. I had little problem putting spice on a bowl of weed and doing it that way so I don't know what to think. Just thought I put this out there for anyone thinking of going down the same path. Much more trouble than I expected. Boiling off the vinegar in a spoon isn't a straight forward as expected. Hence, I think vaping technique needs to be developed before trying this so you can know if your doing the boiling off for the right amount of time. I mainly went this route to try not to waste spice and have a way to accurately dose. Wish I had just made spice enhanced weed now. Might see if I can do that w/ half the vinegar tincture. Just throw some weed in and evap the vinegar off w/ a little heat.

I never understood how the machine was any good. I couldn't get it to Vape without applying flame to the copper and you don't want that. Even with steel mesh its a bad idea to let the flame touch the mesh. If the sandwich method works I say stick with it or go with the GVG. After I got the GVG and tried it I Hve no reason to use any other method. It just works too good.

Also I advise against torching the mesh before using it. The only thing on it is an oil used during the manufacturing process that can be easily removed by soaking in acetone or some other equivalent solvent. Torching the mesh up causes it too oxidize. Especially if your getting metallic taste you know your inhaling bad vapors.

If you have a bong, make changa. Less than 10 minutes work, no solvents needed

I can get it to vape w/ out touching the flame to it. I read about the oxidizing, but I wasn't convinced I wouldn't oxidize it during the vaping process and I figured having a layer of oxides on it could help limit the oxidation that happens while vaping. They due appear to flake off, but the dust falls very quickly and I doubt it would get sucked up by my gentle tokes. Might try acetone cleaned mesh ball though. see how it goes.

I already have some changa made that way. I was just looking for a way to get more consistent doses. I don't want to break through but want a way to get moderate doses w/out break through worries. Change might actually work well enough but the stuff I made was NMT/spice mix and its very unpredictable. When its not giving visuals it takes a bigger dose to get to the super weird head space that is also fun. So, mainly just wished I made spice/weed changa instead of converting to spice-acetate. The changa I'm trying to make from the acetate looks alright though. Evaped most the vinegar off in the toaster oven at 200F. Gonna get the rest out via hairdryer.

Well I haven't tried different mesh yet, but I tried the changa and it sure seems like it's the spice-acetate that does my lungs so wrong. Had the same terrible experience w/ it. Probably need to find a food dehydrator to make that changa acceptable, if it's even possible.
