Cool....I was wondering how that one would look like in person. Just a few days ago I got my first vapcap...a blackwood vong xls.
After using both in water unit and strait off the mouth piece, I realized I needed help with 2 things. Finding the carb quickly and getting a more even heat pattern with a torch. So I made 2 modifications with one being a simple visual aid of applying 2 small colored masking tape pieces at the tip of the vong by the carb and then one 180 degrees opposite. This way I can make sure I heat the cap evenly around its circumference better. I usually spin the vapcap in my one hand both ways. I switch rotations back and forth and it's hard to see exactly where my path of heating is hitting. So if I have 2 polar visual aids when heating, I can make sure its close to even all the way around. Also this helps when quickly putting it into the water unit's joint and finding the carb as quickly as possible to not loose part of the hit.
I had to physically modify the vong body though....I notched out the carb a little to help feel exactly where it is as my eyes and finger dexterity are not the best ....I also tend to use it in darker rooms and such situations.
Wish I could add 1 other change.... to make the bottom of the vong piece to be non-9 sided and just a round shaped conical design to fit higher up and more sealed so I don't have to use the 18mm joint section with the rubber o-ring.
Other than that....this is the most perfect addition to my arizer air. I just have to work on getting better tastes out of it. Vapor is no problem for me....and I can get so ripped with it....my 15 inch water tube gets me totally blasted in 3 good hits where I cant do that with the arizer air. But the air has the best tastes for me and works very well....it just takes more lung power and a much longer session. But then the vapcap is more even more efficient and can get me more ripped quicker.
This is really cool. Particularly the groove to help you find the carb, I like very much. Good work. Love how intrepid the people are here.
