2. If you have the correct size allen key you might want to, (while being very very gentle with the threads), check what level your plate is tightened down to. Too tight or too loose seemed to expedite charring on the OG starburst place in my experience.
I really think at some point the vapman team should transition over to lathing the saucer cap and the smooth nickel plate design. Outside of better clearance where ground glass joints are close to the main body of a glass piece, (you can use a $4 drop down or pass through adapter to solve this anyway), the smaller diameter cap is simply an inferior design from both a usage and aesthetic perspective in every way. It's only a small amount of extra wood so shouldn't cost that much more to produce. I never use the OG anymore; with the saucer cap stirring is easier and hot metal never touches my fingers or those of vape virgins for that matter
