Im not sure on the ethics of this but let's just say any man is more than welcome to create whatever he should like. Period.
Anyway, I would like share with everyone something that I have been working on for two years, Which is about the time I saw the Eclipse Pipe (Essential Vaaaape back then) and wanted to create the same thing myself, For about 80 bucks less considering I had some vials lying around. Through 2 years of tinkering I came to a simple solution that is essentially one of those, Oh that's been lying around the whole time under my nose concepts. So let me unveil it and we can move on. (I dont think it's anything special).

Ok so, Essentially we can see how it works. The same as the Eclipse. Trick being that the carb hole is very small, As it is a groove cut into the wood at a 90 degree tangent. Think pac-man with his mouth open. This allows air into the vial and up the mouthpiece to deliver sweet sweet nectar.
So all the shit I ran into trying to make this thing eventually all came down to the fact that I was just to ignorant to the entire process and it stumped me to one point that I did not try for a long while. As usual the reason something isn't feasible is lack of knowledge.
Pitfall one, Tasted like crap. Couldnt understand why, nor could I get it to taste good no matter what. Thought it might be what I was using to draw the vapor out, Which was a silicon tube attached to the vial just like to my vape wand. Assumed that I needed pyrex vial's as opposed to the regular glass one's I was using. Didnt have much time to piss with it then, Nor did I have oil. So dropped it for a bit.
Got pyrex viles (Borrosillicate Glass) I just bought replacement for the eclipse on ebay. Still tasted crap. Found that I was heating it to much and the tube was gettin to hot and melting, Cant be hitting silicone. So we tried dear antler, Being the redkneck family I have. Considering my father's corncob pipe has lasted him 25 years and well over 100 strains lol, He at first didnt care for vaporizer's but I got him hooked. The antler worked but did not have a very secure fit. Then of course I saw the dole rod. Which worked perfectly, I shaved it to a point to fit further into the vial, The porous wood itself made a good tight hold and seal, And no melted taste.
As for the rest. If your oil tastes bad it's because your not heating the top of the vial enough, The vapor pool's at the bottom and burn's (It doesnt reach flash point but it scorches nonetheless). Thing being that THC and other liquid oil's can vaporize without the need to reach boiling temp's. So the key to the VIAL as I call it, Is to be sure to heat the entire glass, It's extremely important. You barely have to heat it if you do it right. With a normal bic you can get nice smooth tasting visible hit's with maybe 15 seconds of lighter time if that, Less for each hit. I see people on youtube just torching these things to milk their bongs. It's a waste as it's burning alot of the oil in their off and giving them a horrible coughing fit.
Anyway, There it is. Pyrex is god, It disperses heat well. That's why you need pyrex, Otherwise your heat becomes to focused and unspread out around the glass and you burn your oil instead of vape it.
peace
which goes bout 40 on bids on e-bay or amazon.. and its easier to clean than the wooden tube... also looks nice.. and more compact.. but.. u can get 1000 wooden tubes..
