Steve,
Where are you? Feel free to give me a call at 606 423 9854.
I now consider myself an expert plastic welder. I just finished my black tank (88 1/4w x 28 1/2h x 22" d) It has the valves set back in 13", on a 12' x 16' plate, on the lower left rear so I can dump through the bay floor. It also has the rear vertical corners on 45 degree angles to provide lots of clearance for the door arms. Net usable capacity just a tad over 200 gallons. I tested it today with water from the pool & had to redo the teflon tape and gaskets where the valves screw in. It took 3 days to cut, route, weld and test and one of them was just welding in the fittings (4 inlets and 2 outlets)
I pretty well use grumpy dog's method. 3/8" polypropylene, router all edges at 45 degrees 1/2 way through the sheet. I've added a step that helps a lot, it is I tack weld all joints first with a temperature controled soldering iron set at 800 degrees F. I also use the soldering iron as a hot knife to cut off the leftover rod ends. A good speed tip is a big help but you need to learn to use it or it can make very poor welds.

Steve everything that Jerry mentioned works very well, not knowing where the crack in your tank is makes giving any advice difficult, if the damage is on the corner grind out or use a router to prep the area to be welded. The speed tip mentioned makes the difference, they are expensive, i purchased mine through Seely Plastics Gumpydogs site has the address. The speed tip is worth its weight in gold, and comes highly recommended! Seely also sells good polypro welding rod too. The only welding tip is to take your time let the welding gun and tip do the work, pressure is applied while pulling the welding iron towards you while feeding the welding rod into the speed tip. Don't rush it! You will be surprised how easy it actually is, if you have some propro sheet laying around practice a couple of times. Its a snap!......Pat |

mel i bought a plastic welder from Ebay it was around 30 dollars, the speed tip came from Seely Plastics check my site for a link to Gumpydog he has the address and phone number, the speed tip costs around 70 dollars, but it is worth every penny! http://prevostlemirage.blogspot.com/ |
