Hi Mono
Sorry i missed this question,
Bad news I am afraid... HW material is VERY VERY hard to glue, I have asked Japan about this and it is problem there also, the HW material just does not like to be glued!!
It Obviously depends on how much load the joint will be taking but it can be fixed "but probably wont hold" if it is a non load bearing / pressure bearing area by using a two part epoxy glue.
This is ano ngoing problem and if anyone knows of a solution I for one would be very greatful !!!
If I can I use FIRE !! I.e. heat weld/melt the parts, but this is not possible most of the time, only on well hidden joints.
