cityfisher Posted January 31, 2011 Report Posted January 31, 2011 (edited) After running around simcoe today and gathering tones of snow in my tub due to a couple cracks in the plastic, I now need to do some plastic welding , any recommendations on where to get an inexspensive plastic welder in the gta??

Guest ThisPlaceSucks Posted January 31, 2011 Report Posted January 31, 2011 apply drywall tape across the damaged areas and try epoxy?
irishfield Posted January 31, 2011 Report Posted January 31, 2011 Almost impossible to get anything to stick to polyethylene. I've had marginal luck using an old gun style soldering gun.... the HD ones with the 1/8" square looped wire "nose". You'll need some sacrifical polyethylene to melt in, just like soldering pipe with lead. Melt the crack and add/melt filler as you go. Heat/melt/smooth/blend. A fine line between getting it to melt together.. melting a big hole or having a cold weld line that will just crack again.
blue pickeral Posted January 31, 2011 Report Posted January 31, 2011 Mr. Sticky Poly-Bonder http://a-a-i.net/polybonderuses.htm or If it is ABS you need epoxy with methocrylate in it. Permatex makes this.
bushart Posted January 31, 2011 Report Posted January 31, 2011 Just watch the fumes----welding plastic is extremely hazardous to your health besides being a carcinogen. With so much plastic in the average home---this is why so many people die in house fires by the fumes Years ago I was a tradesman and welding plastic was something we had to learn in trades school. If it was me---I'd find an alternative
cityfisher Posted January 31, 2011 Author Report Posted January 31, 2011 I would use jb weld I stopped by Walmart this am and picked up 2 different JB welds. http://jbweld.net/products/water.php & http://jbweld.net/products/jbweld.php Not sure which one im going to use but I will give the repair a test this weekend on quinte
2advanced Posted January 31, 2011 Report Posted January 31, 2011 The second one is good enough.. I would make the crack bigger (wider) and both sides with coarse sand paper and apply on both sides and fill the crack
wallyboss Posted January 31, 2011 Report Posted January 31, 2011 What I did was drilled holes on either side of the crack tiewrapped it closed then I put on some Marine GOOP that I picked up at CTC.

Rattletrap2 Posted January 31, 2011 Report Posted January 31, 2011 If your sled is made with HDPE (High Density Polyethylene), then nothing will stick to it except itself. It will be embossed somewhere on the plastic, likely near the manufacturing info. Just cut up a 5 gallon bucket (preferably black) into strips and use a heat gun from Crappy Tire to melt it in. Practice on the remains of the bucket first. I have repaired plastic floatation like this many times. Good luck.
2advanced Posted January 31, 2011 Report Posted January 31, 2011 Just get metal or plastic sheet and rivet that bad boy
Terry Posted January 31, 2011 Report Posted January 31, 2011 on the weekend I dented in 2 spots on the front of my portable hut I am afraid to knock them back out for fear it will crack nasty hitting a ice wall going 40 miles an hour

Mike01 Posted January 31, 2011 Report Posted January 31, 2011 My clam got beat up pretty bad a couple of years ago. I fiberglasses a good portion of the bottom and its still holding up.
cityfisher Posted January 31, 2011 Author Report Posted January 31, 2011 I fiberglass coated the bottem of the clam with resin and it held up for 2 days then ripped off My clam got beat up pretty bad a couple of years ago. I fiberglasses a good portion of the bottom and its still holding up.
Rattletrap2 Posted January 31, 2011 Report Posted January 31, 2011 Fiberglass resin is probably better than many epoxies, but as I said, it is only a matter of time before it cracks off. That is one of the peculiarities of HDPE. It really only bonds with itself.
mercman Posted January 31, 2011 Report Posted January 31, 2011 oops, misread the title......thought it said plastic wedding
GBW Posted January 31, 2011 Report Posted January 31, 2011 Please let me know how you make out as my clam 2000 has a crack as well.

cityfisher Posted January 31, 2011 Author Report Posted January 31, 2011 Duct Tape! HH doesnt hold either... tried that on sunday

fishindude Posted January 31, 2011 Report Posted January 31, 2011 I'll echo what Rattletrap has already said, polyethylene will only bond to itself. I believe this MAY work http://www.mec.ca/Products/product_detail.jsp?PRODUCT%3C%3Eprd_id=845524442631453&FOLDER%3C%3Efolder_id=2534374302882912 Skiers and snowboarders use it to repair cracks and gouges on the base, it's also fairly easy to use; just light up and drip it into the cleaned work area. Should be readily available at any reputable ski/snowboard shop. Hope this helps, Cheers
