As far as the Pod itself, first impressions are very impressive. It runs as good as it looks. It's been plugged in 24/7 and I've settled on 13.6 as a good vaping voltage. It produces a good amount of heat and the holes on the top half let out enough for me to feel little "hot spots" where the holes are. I haven't looked much at the internals, nor the cord as they are working fine. My wife says I need to get rid of the see-through 1970's power cord.

Using the direct draw stem and I found it's short length and dry draw a little too harsh for me. This is no different then any of my other vapes, I just don't care for direct draw. If I were to change anything about the direct draw it would be a longer stem.

One of the things I had to adjust for with the WPA was the screen. I found the weave a little too open. I also had trouble keeping it at one depth, so I ended up replacing it with another larger screen with a tighter weave. I found a drill bit that fit inside the WPA with a little wiggle room and crimped the screen around it with some pliers, and pushed it in. The larger size of the screen gave it a little more grip.
I tried different bowl "sizes" by moving the screen up and down, with a deeper bowl it seemed that the top would get nicely toasted but the bottom would stay a little green. So I ended up setting it fairly close to the top for a smaller bowl. I found this way it gets nicely toasted in the first hit.
Thanks for the informative post. The pods do look nicer in real life than in the photos, don't they?
I can understand your wife's opinion about the cord. There is certainly a danger it could be considered kitsch but I just happen to really like copper as an element, and I think the colour goes well with the pod.
I agree that a longer stem can help cool the vapour. I've tried a direct draw stem that's 50% longer than my current ones, and while the vapour was noticeably cooler, I don't think it makes a lot of difference in the overall direct draw experience. I also didn't like putting the pod down with the stem sticking out of it, as it feels unstable. So I think I will leave the length of the stems the same for mainly practical reasons. Anyone who wants smoother vapour can use water filtration.
I'll look into the finer screens, however I do like the current ones because they don't seem to clog too easily. I'll be interested to hear other opinions about this. As for the fit of the screen, this is an area that needs improvement. At the moment I'm getting inconsistent results with some screens gripping the inside of the glass better than others. It's great that you were able to make a new screen using a tool you had around. I've tried to keep the stems and screens as simple as possible so that pod owners can easily replace or repair them. I've tried some different screen shapes but maybe I need to do more research in this area.
I've always felt that a more-or-less "square" load is optimal, although if I pack tightly then a shallow load can work well too. I don't know what difference it makes but I chop my herb a lot more finely than you.
I still think more refined stems/screens would be a good thing.
Hazy...I think you could go one of two ways with this vape. You could go the minimalist, MFLB route which emphasized simplicity and nature. The POD lends itself to this easily given its natural form (btw, I found myself wondering what they look like before you get your hands on them, like in the wild...there's probably a pic of them in the front of this thread), and in this case I think your simple stem screens would fit the niche. Or, you could go the fully refined work of art route, which I think would call for stems like Alan's along with an elegant VVPS solution (you've already got the POD itself down as far as art is concerned). The POD also lends itself to this as well. It is exquisitely finished. I love how the heat port is flush with the top and how the plug inlet is well hidden underneath. This seed pod just seems to have been made for this application...you really have found the perfect housing for this type of vape...well done!
As for testing, this design (log vape) has been through the ringer for years and works fine. It works as well or better than any other log vape I have had. The only things I think are worth testing at this point are taste and durability. Taste because you are using glass. Durability because you are new to the game. But I already think this thing is a winner and anyone would be lucky to get one.
Thanks for your thoughtful observations. It's true I could go two ways, but I have opted for the simpler, more affordable route. I know this may disappoint some, however, the entire motivation for this vape was to create a simpler, cost effective design. The fact that it looks great is just a bonus. The original design didn't even use a Banksia pod, but was made from wood and had holes drilled into the side. The market is already well served with the more refined approach, and the other logs out there are high quality and good value for money. I'm aiming to keep costs low so that more people have access to a quality vaping experience. I'd like to streamline production and hopefully lower prices over time.
I've got a question for you all. What do you think about the size of the heat port and the way the stems fit into it? Do you find it too loose/too tight, too shallow/too deep? I was thinking of a slight modification to the design, making the hole in the top of the pod 1mm larger diameter. This means that the stems would flop around a bit more (or that the pod would flop around on the stem if you're using a bong). Do you see this as a problem? The reason I am thinking about this is to enable some other stems to fit. I have also noticed that some glass manufacturers only offer 13mm tubing rather than the 12mm tubing that I use. The pod would be more versatile but the 12mm stems are going to have a lot of wiggle room.
