I have been working on another project with
@Bravesst for a little while now and it is time to reveal the Square Heat Island. Thanks so much to
@Bravesst for working with me on this. It turned out great.
The goal was to create a more affordable and more readily available version of the Heat Island.
@Bravesst is better at making square shapes than I, so he is making square shaped bodies for me (and doing a fantastic job). I am finishing the wood and installing stainless steel heater covers (including power socket and heater). There are four stainless steel heater cover options available.
The two on the left are 7/16” OD and the two on the right are 3/8” OD. The larger diameter heater covers will use the larger 95J20RE heater. The smaller heater cover will use the 25J20RE heater.
The square Heat Island shown is maple / walnut w/ the taller/larger ss heater cover. The top wood is connected to the bottom wood with the same two ss screws that hold the heater cover down, so there is no glue involved as usual. It is 1-3/4” square by 3-3/4” tall. The power socket is recessed and threaded into the side so there is no hot metal to touch when the plug is inserted. The square shape makes it more stable than a round shape so it is less likely to fall over. The shorter ss heater covers are for a 1/2” shorter sized Heat Island.
The starting price for a combination of either maple, walnut, or cherry will be $100 and includes a 4” long 3/8” all stainless steel roasting tube. Power supplies will be extra and there are several options.
2 amp, 0-12v variable voltage power supply w/ digital display - $18.
2 amp, 12v fixed voltage power supply - $15
DC extension cord w/ right angle plug end - $5
25w, 0.5v-25v voltage controller (requires fixed voltage PS and DC extension cord) - $35
12 is a good voltage, but flavor can be a bit better at lower voltages. Allowing room air to leak into the roasting tube is a good way to manually control the roast temperature.
The plan is to have square Heat Islands available to purchase w/o the need to get on the waiting list since I won’t need to spend any time making wooden bodies.
I am also planning a batch of bamboo Heat Islands now that I have some of the new larger size ss heater covers made. I may also try making a 12mm glass heater cover Heat Island using the new 95J20RE heaters. So many options are now available.
I will also be able to turn round shaped custom Heat Islands and assemble them the same way w/ the two ss screws.
Air/Solo glass stems work perfectly for the larger size ss heater covers. Hope to have some for sale soon. May have some smaller size (1-1/2”) square Heat Islands made w/ the small size ss heater covers if there is enough interest.
Exotic woods are always an option for the future or for custom units.
@RogueGuy - Glad you are enjoying the Heat Island. It is so nice to have roasting tubes that can be used in multiple vaporizers. That is the way it should be.
