@oddjobold - Glad to hear you are enjoying your iHeat. Will be really nice when your Witcher arrives. Enjoy.
@PPN - Very cool that you found another side by side mod into which the iHeat will fit. Nice to have two batteries for longer time between charges. I never charge the batteries in the mod anyhow so the usb is not a big deal to me.
Here is one of my latest body styles for the iHeat. It is a pineapple shape turned from osage orange wood. Was trying it in this wood before turning one from some more expensive wood. It is about 1.5" in diameter, so a bit bigger than the normal size.
I have also been working on a new glass cooling tube. The farther you can get away from the heat source, the less heat will get to you. How to extend the length without making it too long to handle? I found the answer in test tubes with side arm attachments.
An 8" long 13mm glass tube is connected to the test tube with a silicone sleeve. There is another small silicone sleeve at the end of the 13mm tube inside the test tube to prevent it from crashing into the side of the test tube if dropped. It uses a 10mm ss basket screen that can be positioned anywhere in the tube. The 18mm taper of the iHeat will seal to the silicone sleeve and allow the tip of the 13mm glass tube close to the heater screen in the iHeat. The end of the 13mm glass tube can be moved around within the iHeat to expose different parts of the screen to the hottest places for a more even roast. Since the ID of the 13mm glass tube is 10mm, it will also work with the Heat Island and Toasty Top.
It does take two hands for the glass cooling wand since it is not a tapered connection. Wouldn't want to drop it anyhow. I hold the bottom end of the test tube in my left hand so that I can feel the glass start to get hot and then I know it is time to back off the heat. I rely on the feeling of hot vapor on my lips for the wooden tube to know when to back off the heat. It is very easy to get hits that are too large to handle since the cooling is so effective. The vapor must travel about 16" through the glass tube / test tube before it reaches your mouth. It seems like the heat can't make the abrupt change in direction and concentrates at the end of the test tube. It is also possible to attach a silicone hose for even more cooling length.
Another option is to place some hemp fiber in the bottom of the test tube to catch large particles.
Since everything is straight, it is super easy to clean. The silicone sleeves can be replaced when necessary. Everything can be cleaned with alcohol.
It will work with quite a few other vaporizers too. Anything with a female 18mm connection or a 3/8" tube (glass or metal).
