I agree wholeheartedly with these DIY adventures. The 510 mods are the best. End of story.
However, I honestly gave up on using TC with my Project. I've tried many mods and some work OK but find myself always fiddling. I love my latest mod which is a
Vapefly Brunhilde SBS. The widest 25mm SBS I found and fits the Project perfectly. The 21700 battery is just right for a full day of vaping for me. 6-7 bowls + my trusty DIY vape pen works out well for me. The Vapefly works with my project in TC Ti mode in the lowest temperature settings or in SS mode in the highest temp settings. No programmable options. However, the same consistency problem as other mods. Seems to act differently every time you change the battery. Likely the reading of resistance is different each time. Regardless, back to fiddling.
The solution is what
@PPN has been doing. I now just use power mode around 34 watts and control the temp with inhaling speed. No-fuss and no fiddling. Just fill and get high.
As for those hot spots, I added a modded
stainless steel key ring. It took me a while to find 100% SS as most keyrings are made of unknown metals and should not go into the vapor path. I tested these ones by heating one over and over and checked that it would still wipe clean and have no signs of off-gassing. Come out as smooth as new so I think this is good SS. Anyway, be very careful what goes into the vapor path.
So I bend it so it will go under and around the outside of the heater screen and then goes through the screen with a finger that comes through the screen on an angle such that when I twist the bowl, the goods get stirred. Since the bowl gets hot, I added more Orings to the outside to make the twisting easier on the fingers. I found I have to reduce the load to about 60-70% in filling the bowl. Still lasts a long time.
This is still my go-to vape after a few years now without any needed maintenance. I just haven't seen any on-demand unit this works so well with minimum maintenance.
