Right then, here are the pics of what I used. I will also type up the description and directions of use, and add a link to the company where you can buy it. Dont be alarmed at the price as it is for 12 bottles of the stuff.
PLASTIC WELD.
Use plastic weld to cement any of the following plastics to each other or in any other combination; Styrene, Butyrate, ABS,Acrylic (Lucite or Plexiglas), Perspex.
Diretions.
Plastic weld disolves a thin film of each surface to be joined then evaporates very quickly forming a welded joint - one as strong as the surrounding plastic. For best results, hold the pieces to be joined; use a small brush to apply Plastic Weld. Capillary action will spread it the length and bredth of the joint, forming a continuous solid weld. If the brush stiffens when dry, dip it in Plastic Weld to soften. DO NOT USE ON STYROFOAM.
