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
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.
Step 2: The Elbowy Bit
You need to seal the remaining holes, you can do this with some tape (but use stong tape because of the heat) or try to find some other solution, i think i will make a fabric seal for around the cooker.
you can test the seal by just pouring some water in the cooker, putting the elbow on an turning it on, if steam escapes somewhere, then there still is a hole there. A little steam isn't a problem but if more steam stays in the tube its better.
Step 3: The Modular End
i just us a simple pipe that i close of with a wet cloth. the biggest problem is that the end of the tube deforms because of the heat.
now just pour water into it and start it up, i just leave my watercooker running and refill it when needed.
When i do some changes to the thing i will edit this instructables.
