Acrylic Repairs

[Railskinner]

I purchased a calcium reactor that was a DIY ,has being working for 1 1/2 yrs
i noticed on one of the seams that there is a little salt creep starting to show at the bottom on main reactor chamber. The reactor is a 2 piece set up system with main reactor going to an extra chamber for more media.Where does a person get weld on 16 ,if thats what i use for the repair. It will have to go on the outside as the chamber is only 4" wide ,16" tall. Also needed repair is the second chamber .The top end needs a new flange to be made and welded back onto the 5" cylinder. Is there any acrylic dudes out there able to help? Red Deer area would be sweet
