So then what are your thoughts on the mass of the V2 cap setup and that when you add the mass of the intended cap, the nail drops to the point you're effecting you vapor negatively? It seems Dnail is agreeing with me that heated mass makes for, if not "better" vaporization, easier, more stable, more consistent draws. Again, I'm not saying the Halo needs the retainer on the coil, because they already use the massive cap.....if the cap was not intended to be a heated mass to help keep the heat stable, they would have made it with less metal....there is no other reason to make the cap with that much solid mass....none. I may not have the science on lock to a point i can get my point across but money is money and business is business and dnail is too smart to be that dumb.
I don't feel this is a matter of style or opinions, I'm pretty sure this is basic thermodynamics. since all I'm arguing is the mass of the Liger is anything but a failure of engineering as its the exact same principal as a cistern, a capacitor, a network buffer, etc etc, its not storing a temperature, its storing a volume of heat. I may not know how to correctly explain my thought but if adding an intermediate material alter the temperature in a negative way, i doubt they would have made clad pans and cooking surfaces as the high end solution. You say dabs are not like cooking but i challenge you to watch people working with sugars and caramels and tell me that isn't 99.9999999999999999999% exactly like the crap we go through working with and dabbing waxes and oils. Ive filled the buckets of both ligers to the brim, and caused quite a mess.....no delayed temp drop on the coil...whatsoever. If I'm following your thought correctly, and i may not be, you say the SIC should somehow suck the heat from the ti and will cool it down in some appreciable level, and that somehow makes the coil fire up after the fact to heat the ti, but that just is not what happens, i can record the Hex nails temp charts to prove it.
TLDR version
Both dnail and CCA know wtf they are doing, its the exact same song just done to different beats.
Apologies for the delayed reply, I have been massively busy and missed the notification.
My thoughts on the mass of the V2 carb cap from D-nail (and necessity to pre-heat it when dabbing at low temperatures to prevent it sucking heat out of the *particularly SiC* halo [it does not exhibit nearly the degree of heat sucking-ness when used with either quartz or sapphire Halo's] - SiC's amazing thermal conductivity meets it downfall here) is that the mass of that cap is an engineering oversight, and I wish daily for a borosilicate glass or quartz carb cap that would not be so subject to heat transfer from the SiC dish. I think D-nail just machined the cap to fit a variety of size of nails and its size is what it needs to be to meet the edge of the Halo and provide a great seal, without doing much to mitigate the heat transfer from the SiC dish. I should add, I've tried a friends D-nail 2.0, and it seems to experience a pretty similar drop upon capping with as my Auber PID box. Maybe not quite so bad but still significant.
When I use a glass dish to carb my Halo, I don't experience nearly the temperature drop upon capping.
I understand your belief (and agree with it) that Liger's design to use a large mass of a Ti heatsink is a valid way to stabilize heat. I do think you have failed to understand my point that while a heat sink is a great way to stabilize heat between a surface that you want heated to a precise temperature, and a small heater, it is the exact OPPOSITE thing you want to put between a surface you want heated to a precise temperature, and the temperature-measuring device that you are using to measure the temperature of that surface. Putting a heat sink subject to a temperature drop across its mass does no favors for the accuracy of the thermocouple attempting to measure the temperature of that heated surface. My point in describing what I consider more proper engineering of the D-nail halo is to explain that D-nail has placed the thermocouple, whose job it is to measure the temperature of the dabbing surface, in DIRECT contact with the piece that is that dabbing surface.. When the dabbing surface's material is made of a material which transfers heat fantastically, it is very easy for the thermocouple to send an accurate temperature to the PID controller, which can then regulate the power sent to the heater, which also happens to be in very close contact with the dabbing surface; there is a narrower margin of error in that closed loop system. You say it is like 'riding lightning' in my opinion it's simply exhibiting more change because it is more quickly registering the drop in temperature of a very conductive material (SiC, and to a slightly lesser extent Sapphire) compared to the Liger which can't measure those small changes (nor respond to them)
When you have a heater wrapped around a titanium heat sink and its job is to heat that heat sink, the thermocouple of the heating coil is only in contact with that heat sink, and its ability to measure temperature is dependent on the thermal transfer characteristics of the heat sink material. The fact is that titanium has an ability to transfer heat that is orders of magnitude worse than Silicon Carbide, so putting a silicon carbide dish inside of the titanium does NO favors for increasing accuracy of temperature measurement. I have used heaters run off PID controllers for a variety of tasks and can say unequivocally that getting proper temperature measurement of the 'control surface' is of paramount importance to narrowing the oscillation of surface temperatures. Putting heat sinks between your instrumentation and control surface just does not make sense to me.
If you want to make some useful charts with your Hex nail, you will have to keep in mind the difference between temperature your thermocouple measures, and temperature at the control surface. As I have done my best to explain, the temperature your Hex nail is reporting is based on the thermocouple embedded in the coil, which is "behind" the actual temperature of the insert inside your Liger. To gather useful data to validate or disprove your theory will require some basic datalogging capability with an independent K type thermocouple placed on the control surface so you can plot the ΔT between the coil's thermocouple (and what the Hex nail sees) compared to the control surface (the top of your insert where you apply your dab) over the course of a dab. Figure out how to do THAT while capping the Liger, and you're 90% of the way to solving the entire problem I've been discussing.
FWIW, it's a step similar to guys building rosin presses with E nail coils, very quickly realizing the thermocouples used in the coils weren't coming close to providing accuracy when it comes to temperature at the control surface, and changing designs so that separate heaters and temperature sensors could be used- temperature sensors embedded in the 'control surface' to accurately measure its temperature.
You are most welcome to your own opinion, but that's mine!
I do apologize for the edits again, as I misspelled a ton of words, and probably didn't catch them all. I'll surely appreciate reading your response, but I'm out of time for any more myself with work and life these days. Happy dabbing on both your setups; I sure hope I have the chance to try a newer-generation, larger diameter Liger and re-asses my thoughts on the continually newest-revisions CCA always seems to be putting out. Happy dabbin'!
