For the screen in the bottom of a glass bowl, I form the screen in a dome with the edges lifted from the bottom. Right now I am using one of the bowls that come with the Ispire Wand and I have one other glass, but it has a single hole with no screen. It works OK, but draw is limited.
Still thinking about shovel head on one side of the Flower Pot and Injector on the other.
I did it with a B1 and WeedEater.
B1 bottom nut al most full of balls.
WeedEater top nut.
NOW Cut the post out of the WeedEater Bottom nut and screw it into the top of the top Weedeater nut so its sticking out the top. this will hold the balls in.
Male on the top, female on the bottom.
I don't do pictures here, but I did screw it together and use it last night. I have not Cut the post from the bottom WeedEater nut yet. Probably Monday when I have access to machine shop at work. It did work as an assemblely. I needed about 25 * f more than I had.
I think the total bottom nut from the WeedEater is sinking some heat out. Once the post is cut off, it will be smaller and less heat sinking. It will add mass.
I think it will heat the extra Ti because in the stand, the "injector" is on top of the balls and heat rises.
When I used it last night, it did not matter which side I used. Performance was the same. I allow more time for warm up.
