This instructables will show you how i build my modular woodsteamer, it is still a bit of a work in progress but you can use the thing if you want. The system is useable but i want to make it easier to set up and remove.
Things you will need:
1- 90° PVC pipe elbow diameter 110mm (choose one that almost fits the top of your watercooker
1-PVC pipe lengt is your own choice
1- old towel
some wood to support the pipe
if you want to steam bigger things like a board, you can use a styrofoam box where you cut a hole in and jam a piece of PVC tube in.
Tool you need:
a hacksaw (or use a angle grinder or dremel)
a Angle grinder with a cutting blade (optional)
a dremel with a cutting wheel (optional)
tape or glue ( don't use hotmelt because it WILL melt when the steamer is used)
some things i still need to do or work out myself:
the end of the PVC tube keeps deforming from the heat
i need to build a support for the tube
the cuts in the elbow need to be refined a bit and sealed off.
Step 1: the watercooker bit
WARNING don't do this if you don't know anything about electricity. I had an old watercooker that didn't turn on so i screwed open the thing and found out the switch was broken. since i didn't really need a switch (i just pull the plug) i just rewired the heating element to a powercord, making sure no wires touch the heating element i taped everything shut ( i broke some connections while opening it)
The problem is, that it is possible the heating element overheats and melts, to prevent this there always needs to be water in the cooker when its turned on.
If you want to sacrifice a working cooker, then you don't need to do this step, but you may want to tape the button in place, if the cooker has an auto off function.
