Anyone know where I can get custom made holding tanks for the black and grey water? Does anyone know what happened to Best Plastics? That is where I have gotten them from before but their phone # is no longer a working number. |

Casi,
You reference Best Plastics but mention "custom made". By custom made holding tanks do you mean like the style/design found at Gumpydog's site? Built up from flat stock and hot air welded?
As compared to Ardemco and the like, using Gumpydog's approach, you can tailor your tanks specifically for your space, use and application.
2D, what are you changing over from? I'd thought an ol' Hawaiian guy like you would be using old Coconut Shells before going to an aluminum tank!
Heck, if I was tough enough and lived in Florida, I'd a caught an alligator, hollowed him out, and spun welded a fitting! LOL!!
Back to Casi, I'm interested in building holding tanks like Gumpy. I'm not at that stage yet. But I've got a Leister 1600W welder with a speed tip, etc., that I want to try out. This is about twice the output of what Gumpy used so it should be adequate for the job.
If you're planning on attending Busn'2005 in Oregon this July, send me dimensions and spring for the material and I'll do the labor for the practice and deliver them to the rally.

Marc,
What I mean by custom made is that I want tanks built a specific size to fit where I am putting them.

I'm giving the Gumpy thing a try, the plastic welder is here, polypro should be here this week, I can't wait, I just have to give it a try I'll let everyone know how it turns out, if this works it should cut my water tank price in half, if not....well.............besides with the directions and information that Gumpy gives why not give it a shot, this should be interesting, if mine turns out half as good as Gumpy's, I will be satisfied. |

Casi,I had mine made from 1/2" welded plastic by DMH Plastic, 333 Enterprise St, Unit B, Ocoee, Fl. 34761, Phone 407-489-2708. The guy did a great job, he made them exactly as I had them drawn. Dave |

There no glue to stick to Polyethylene but can heat weld to it.

Caution; If you go to welding plastic, be sure test your weld for strengths on corner sample.
Good penetration is having material edge same temp as melted plastic flow on.
It not fun smelling toxic flume & if not careful you will be in coffin in three days. Few firemen die later from burning Zerox copy machine. Now they wear mask before enter building. Light breeze over it to avoid inhale fume should be OK.

At DuraCast near Lake Wales Fl. have custom size tanks of all shape & size in their yard.

You can fax them your shape & size and location of fitting. See what happen.
FWIW

After reading Jerry's post i began to think, i wonder what the MSDS sheets say, well i ran a google and found a free site with MSDS sheets on polyproplene sheet, the MSDS sheet says there isn't any bad effects from polyproplene sheet, other than dust, i've read several of the product sheets, they all seem to say the same thing. Does anyone know of any other site that talks about welding polypropylene health risks? |

Just finished welding my 3 tanks. (polypropylene) fresh-130gal, black-68gal, grey-48gal. Really pleased with the outcome. took me about three weeks to complete. I will be glad to talk to anyone interested about some suggestions.
I have photos but don't know how to post them. John |

I've followed Grumpydog's directions except I used a Steinel heat gun. The Steinel speed tip is a POS and must be modifyed significantly but can be made to work. The Makita heat gun is probably the lowest cost way to a competent plastic welding set up. I'm tacking everything with a temperature controlled soldering iron which I also use as a 'hot knife' to cut away the rod ends. I've finished one(95gal) of two fresh water tanks (175 total) and a 4 gallon resevouir tank for my Webasto. My combined waste tank will be about 200 gal. My fresh tanks are located under twin beds. My tanks are quite complex because I'm trying to get maximum capacity and allow channels for wiring and plumbing or in the case of the Webasto tank fit it in a very funny place. I'd strongly recommend Grumpydog's technique of beveling the edges 1/2 way through the 3/8" polypropylene then filling the 'v' groove with multiple passes of weld (I tried another way and it's clearly inferior). One must be continuously on the lookout for air pockets and cut them out and reweld. I use a 'Dremel' tool with a 1/8" router bit to cut out the air pockets. One of the disadvantages of a speed tip is that it's easier to make air pockets. I've tested my tanks by 'blowing them up' with lung power through a check valve installed in the only unplugged opening and seeing if they hold air overnight. I've used the kid's bubble soap to find some pinholes I had in the corners of the lid to tank weld. I repaired the pinholes by routing out the weld and rewelding (perhaps a bit more carefully). Each tank has taken about a week to complete but I'm getting much faster. Also shop around for materials, I found prices from $75/sheet to $130/sheet and rod from $6.30/pound to $18/pound. I'll gladly answer any questions either via email or phone. lieblerj@alltel.net 606 423 9854

Jerry,
I don't know about the Steinel produt. My Leister has a variable heat control and 1600W power. I think it's not so much the speed tip as the amount of heat the gun can put into the material. Kinda like tuning a wire feed till you get the bacon sizzle, IYKWIM.
Bubble formation is/are attributed to moisture. On a closed system using Nitrogen is possible. I've got a refrigerated dryer on the shop compressed air supply. It should be cheaper than Nitrogen.
The site Sojourner gave us the other day specifies a 60-70 deg relief angle on joints. |

Something I found to be very benificial: I routed a V groove(1/8"deep in 3/8" material) and a corrisponding bevel where ever I was going to butt weld two edges together. I was able to put the whole tank together with a few straps and then begin welding.
I had no distortions.
