I am going to make the slot in the base a tiny bit shorter so that there is an equal amount of unrouted wood on each end. The slot needs to be there so you can pull the tube out after it has been pushed in, and also probably helps for removing heat from the tube by allowing air to flow around it.So is it necessary to router the slot in the side or was that just for illustration purposes?
Are you selling those dimple stems or do they come from a third party retailer? For instance, is that a Hulu cooling stem?
I can see how it obviously extends the mouthpiece and makes it more sturdy but does it actually make the vape draw temp any cooler?
Does the smaller dia. tube get shortened so the vape output is cooled thru the dimpled cooling stem, rather than travel the entire distance thru the smaller tube? I couldn't quite determine that from your pic.
Or is the routed opening your design to allow the user to move the cooling stem out and then to retract?
I plan to sell the stems but will also have an option without a stem for people who have one or want to get a different 3rd party one.
Yeah, I think it makes the vapor significantly cooler and the glass doesn't get as hot.
There is still a smaller diameter tube but it is shorter. I'd say it is pretty close to how the vapor is with a stock mp and a hula attached to the end, maybe a tiny bit warmer.
The distance you can pull out the mouthpiece depends on the ceramic mouthpiece part because that's the part that the glass tube slides in and out of. Basically the amount of travel equals the interior length of that ceramic part, between the oring and the opposite end. That distance is 3/4" on the current mp and for cost reason I think it makes sense to use the same part. Making a longer ceramic part adds a lot of cost because of extra material and more complicated tooling to make it and also existing owners would have to buy a new part. I think you can get away with a little more distance though if you were willing to have the stem stick out a little bit even when it is pushed all the way in. Like fully extended it could be 1" and fully retracted it would stick out 1/4". The only difference would be that the narrow tube would have to be slightly longer. Also I should mention - there is no need to hold the fw7 upright. If you hold it upside down or sideways when you draw you should get more nose clearance and as long as you tamp the herbs a bit they will stay in place.Nice work @firewood!
So my question is, how far can the mouthpiece stick out while still remaining in the ceramic housing, can it go out farther than the standard original? If you recall it wasn't such a fan of how close that put my lips and nose to the body of the FW7...
And also of course, the tip of the glass mouthpiece not getting hot, hopefully the cooling spikes help absorb the heat before it can get to the mouthpiece and burn lips!
The tip of the mp definitely does not get as hot, I think due to the spikes and also because there is just a lot more heat capacity in the larger glass tube.
