so I've been trying something similar to the gvg bat (a glass tube) with brillo in the end of it to hold the fb, and just was wondering what the most effective method would be in regaurds to:

How tightly the brillo should be stuffed into the glass?
how to melt or contain the fb within the brillo and how to be sure not to vaporize it?
when smoking, does it matter if a torch lighter or regular is used, how close should it be held, is there a risk of burning?

I did a similiar method, but the tube was also stuck into a bong. I had heated the tube and bent it so the spice wouldnt fall into the bong.

I personally did not like this method. I do not like the flavor that the brillo adds. Yes I cleaned the brillo with a torch before I used it, the flavor is metallic.

It is also more difficult to vaporize than a bulb. Either way, use a torch, start with as little heat as possible, I found it worked better heating up the tip of the glass while also allowing the hot air to move into the tube. The heat from the glass was the more efficient method of heating the air going into the tube to vaporize the DMT.

To melt the DMT. Stick the DMT into the tube just before where you want it to be. Then squeeze the brillo in up against it. Then use a lighter and VERY lightly and SLOWLY heat up the glass until the dmt STARTS to melt and slightly pull away the lighter and then push the brillo slightly farther INTO the DMT. then let it sit more a minute to recrystallize.

when using the torch to vaporize, are you shooting it into the hole or aiming it perpendicular to the tube? also I'm not sure if I am using too much brillo, as it may be preventing hot air to flow through.

The amount of brillo is dependent on the size of the tube. Just experiment with small doses. I have tried both putting the torch flame directly into the tube and perpendicular. I think a combination of both works best. Start by heating up the tube tip with a slight amount of torth flame lightly going in and increase as you end the vape process... this method of smoking DMT is difficult IME and you will probably decided to scrap it after the first few tries.

Have you tried the vaporizer bulb/bong combo yet?

You will burn yourself if you shoot directly into the hole. Aim perpendicularly!

No, I'm not to sure how I would go constructing this

Make a machine! Cheap easy way blast off.
I use a vinegar bottle (glass kind with metal top at fish n chip places). Just drill a hole in the bottom.
Works REALLY well!!!

Can't go wrong with the Key v2

this. i am normally the only one suggesting this method, but it works so incredibly well (especially for enhanced leaf/changa)

I found a meth pipe with a long tube they usually fit really well into an acrylic thumb carb bong. Take a large propane torch and heat up the tube to bend it so that it is horizontal coming out of the bong

Does this work much better than the pipe on its own?

Put your DMT in some herb, put the herb in a bong, booooooom jobs a goodun.

Easy.
