@KeroZen , No problems here, communal discussion is important!
In case of a prolonged misfire, constant on with no airflow. There would be other things I'd worry about beyond the PEEK. Mainly burning out the coil, browning the wood body, and most of all, heating the 18650 cell or over draining.
And just so we're clear, there are two safety measures I took to make sure that doesn't happen. One, the button itself is difficult to accidentally depress, it's not what you might call a hair trigger, the throw is relatively long, and the spring pressure is enough to resist, say.. the pressure of your pocket.
But more importantly, there IS a hard OFF lock feature that breaks the circuit. It's built into the design of the connector bridge. When swiveled, and the locking screw slightly tightened with your finger, the bridge is locked into place. You physically can't swivel the bridge back into a position without breaking the device.
I would definitely encourage everyone to engage this safety when the vape is not in use, as it guarantees no misfire is possible.
Also keep in mind that the massive bronze bottom plate is a huge heat sink that has a fairly large contact area with the heater module. Any heat that travels back down the shell (which is thin SS, so not very good at transferring heat in the first place) is conducted into the bronze bottom plate. In my mind, this is an important safety feature and part of the reason I used a thick bottom plate. Non of this gets hot in use, but in case of a misfire, I think it will soak up a lot of the excess heat and channel it away from the more heat sensitive areas.
In case you are interested,
here is the PEEK I used. This material isn't like a consumer-grade plastic, it needs to be made to very strict guidelines. This stuff is used in extreme vacuum (because of it's purity, high temp, low outgassing, etc..) and it's put into peoples bodies for medical implants etc.
But yes, there is definitely a stigma around plastics in general, and I think that alone is perhaps worth the change. The average consumer is not going to be knowledgeable in the nuances of PEEK, ha.
A. Blackwood, like a lot of the dense exotics, is relatively high in resin content. With thin-walled smoking pipes, I noticed the effect you're talking about, with a slight oozing of the resin on the outside of the wood. This was mostly a result of abuse, burning the pipe too hot. The resins can be wiped off, and in my experience, smells pleasant, just like it smells when you machine A. blackwood, sort of sweet candy like.
But, the insulator end of the Nomad HM does not reach temperatures anywhere near what would be required to do this. I've never noticed this effect here. Also, the part is so small that the actual resin content would most likely be negligible compared to a larger body of wood.
@szai , A very good point. In normal use, you're bound to have a few exhale events that blow a bit of vapor back down the stem into the heater module. I have soaked the heater end of my module in acetone a few times to clean it, but don't submerge the wood.
I have a feeling that A. Blackwood would be able to take being boiled and soaked in ISO, but the cracking risks increase with that sort of abuse.
hmmm... what to do...
