<![CDATA[Plastic Welding / Holding Tanks]]>Anyone do plastic welding? I need some custom-sized holding tanks made for an RV. Potable, grey, and black water tanks, about 22" wide and around 9" tall, in various lengths up to 10ft. Would need fittings installed as well. Fresh water tank would need internal baffles.

Anyone been there / done that on RV tanks?

The process is simple really for fixing cracked plastic - just grind a "V" into the cracked area and then with a soldering iron w/ plastic weld tip on it just heat up the plastic welding rod and push the molten plastic into the aforementioned "V" making sure to heat(melt) the original material as well to blend it all together. I'm assuming the same process would be required for a new construction custom holding tank like you need as well.

If it were my project I'd give it a try myself, but since it is someone else's I wouldn't feel comfortable doing this.
