That's exactly what it was designed for.
I think wires have been crossed and Stickstones has assumed somevody was querying the idea of the WS heating the actual cap, like an alternative heat source for the standard vapcap function.
So I think he may have misunderstood your main enquiry of the differences between the various methods of heating the vapcap, and in comparison to the WS which uses the Ti tip.
A fair enquriy I say! I can't comment on the Woodscents, but I own the Omnivap and Pipes IH.
There are definitely differences between the induction heater and the torch. I unquestionably get a far more even and complete extraction with the torch than the IH, with even browning top to bottom.
I always find the top part of the load is very dark, nearly black with the IH, while the underneath is still unevenly extracted. I dont bother stirring my vapcap. If the abv isn't too dark I just save it for edibles, so there is a bonus to not using it all up. But with the Induction Heater, I scrape the top, blackened material off first to see if the underneath is worth saving to cook.
I also found that the vapor production declines slightly sooner with the induction heater and has pretty much stopped long before the cool down click. Using the torch the vapor declines nearer to the cooldown click.
I always have to go at least a few seconds past click with the IH to get a decent hit or certainly it is essential to milk glass. I am uneasy about my varying ability to judge time passing, and to remember where the sweet spot is, without pushing it too far and getting more irritating, higher heat vapor.
It can be a hard line to consistently draw, I don't want hits that are airy and mostly invisible, nor hits that are too irritating for my sensitive lungs.
Using the torch I generally stick to the click, or continue to rotate for another second. If I'm not achieving the large hits I like I move the flame around and nearer to the cap, but I feel that is more control over this than the Induction Heater where I am relying on my judgement of time and memory, with the torch there is a "feel" for what you are doing with useful feedback.
I use both methods actually, for the pros and cons of each. The Induction Heater saves my hands, it is much harder for me to rotate the 18 mm blackwood VonG than the titanium body, so the IH helps here.
For some reason I find the hits from the torch more satisfying. Maybe because I feel like I have partaken, with involvement and ritual- a massive appeal with the Vapcaps in general. The IH is a bit like waiting for your ticket to be called out at the delicatessan!
Im really not wanting to speak down on the induction heater. It's a fantastic concept and design of several geniuses currently. Nobody has expressed any dissatisfaction with their Jarheads or Portside.
I definitely feel that with the torch the load itself is receiving more heat which enables a more complete extraction at a lower temperature, whereas with the induction heater the cap and the outside of the tip are much warmer relatively than the herb at the time of click. The Induction Heater is definitely more of a convection extraction, although as you have hinted there may be significant conduction from the cap and "tip of the tip". This would account for the way I get unevenly darkened bud at the top of the bowl with the IH.
I have more thoughts about this and much better ones actually, Im so mellow from fresh harvested Autoflowers, I only had 2 bowls in the Omni earlier through bubbler, using the IH in fact. A combo of Think Different and Night Queen. This is the first time ever since being unwell that I actually have a proper harvest of really lovely weed that I am not allergic to (fertilisers).
No need to ration or feel guilty about using more some days! How nice!
