Homebrew PCBs

Sorry for this OT request.

Recently (Back end of last year) there was discussion about making 
tanks and bits from PVC.  There were also recommendations about how to 
weld PVC  - which hot air gun to use etc.

I have purchased a suitable gun and some pvc welding rods but I am 
wasting a lot of material trying to get a reasonable result.  So far 
all my results are disgusting and unusable.  I would appreciate some 
advice with regard to temperatures, types of welding rod and so on.

My gun is a Steinel 2305 and I bought there rods.  Are there better 
types available?  Should I give up and stick to glue (what a failure 
that would be!!)?
