kayak modification and polyethylene welding.wmv

Repair and modify a kayak using a polyethylene welder. Other tools used : propane torch, heat gun, utility knife, small hand planer, serrated knife to cut polyethylene foam. This crudely modified kayak had a trolling motor mounted on the front, battery in the back, PVC fishing rod holders attached with caulking through ragged holes and other crudely cut holes and roughly mounted hardware. All was removed, holes patched and new rod holders installed using 1 1/4" polyethylene conduit. The battery compartment was enlarged and changed into a cooler and storage compartment. Closed with a cover made from 2" poly foam.

A good water catcher is a handball cut in half. I sharpened one end of a piece of thin walled galvanized pipe which cut a perfect hole in the ball when hit sharply with a hammer and the half ball on a 2 x 4. Slid right on the paddle and holds all the water that runs down the handle.

Is it safe to hold plastic from a bucket of hdpe?
I urgently need to heal a kayak, but it is very important for me to do everything securely. Answer me please!
RLZerr
RLZerr - 6 years ago
I might not understand your question. Many buckets are made of HDPE. One way to test plastic is to burn a piece with flame or hot iron. Blow it out and if the smoke smells like a candle it should be polyethylene.

Really nice work! Only thing I would worry about is the holes at the bottom of the pole holders going straight in to the body of the kayak. If your kayak flipped it would definitely let water in. I am sure you would be able to find a way to seal that up pretty easy.

If I could kick my self any harder, Id be in orbit.. I just saw four kyaks at the dump from a local rental company. They had 5 or 6,  2 1/2in holes randomly drilled through the bottoms. I was seconds from grabbing them and thought it was too much work to fix them.. On the look out during next seasons rental clearance. LOL

+Paul TheSkeptic  Polyethylene welder. This one is similar to mine. https://www.austinkayak.com/products/1587/KC-Welder-Pro-with-Hobie-Color-Rod-Stock.html?utm_source=google&utm_medium=cpc&utm_campaign=Shopping:%20ACK%20PLA&scid=scplp286387&gclid=CJSs8LPbhMwCFQUMaQodJOcNIA  Like anything, it takes practice to get good. Practice welding pieces of other polyethylene like water jugs or similar.  plastic that has the triangle symbol "2 HDPE" on the bottom. You know it is polyethylene when you heat it and it smells a little like a blown out candle.

¿Do you use a regular soldering iron? Melting temperature of tin is quite higher than HDPE. Do you use a power regulator so that you can reach the appropiate temperature?
I made some trials on plastic bottles using a regular soldering iron with poor results. I am considering to buy a heat-gun.
RLZerr
RLZerr - 8 years ago
+6koko3 soldering iron is too hot, but if you could find and fit a tip with a larger surface area it would help distribute the heat it could work. For cooler temperatures on small intricate jobs you just need to switch it on and off frequently. I have used a power strip with a switch.

curious y u didn't use real rod holders.
RLZerr
RLZerr - 8 years ago
+s buchanan All the kayaks I've worked on the owners were not concerned on whether they had a fancy commercially molded "cup" to hold a fishing rod upright. I keep scrap material on hand for making simple repairs. When there is concern about water possible getting in the kayak from splashing or tip over it would depend on the design of the kayak and if the rod holder is on a sealed compartment.

LeoTheBattleheart
LeoTheBattleheart - 9 years ago
Okei, can someone explain for dummy. If i buy new sit on top kayak, can i just drill it lot of holes without worrying that i actually destroy my kayak? Does kayak lose some of its floating ability with all those holes in hull? There must be different plastics in kayaks, can all kayaks be modified without worry that you destroy your kayak?
RLZerr
RLZerr - 8 years ago
+LeoTheBattleheart sit on top kayaks typically have sealed airspace for floatation so might not want to have any open holes. To install a fishing rod holder you would want one completely sealed

the splash guard of my car was ripped to shreds by my car tire and I was inspired by this video to weld it all back together and it was a big success.  I just used a wood burner and modified it with an iron tip to reduce its heat and it worked perfect.  No need for a special plastic welder tool or even those repair sticks.  Scrap plastic works fine for adding molten plastic for patching material.

Is it possible to sand it after its cooled down to get the same smooth surface as the rest of the kayak?
8tonsemi
8tonsemi - 9 years ago
Thats should be fine except if your trying to blend colors just don't sand past the color you want and you should be good. It will also help if you use automotive wet/dry sand paper dipped in water to keep the dust down.

RLZerr
RLZerr - 10 years ago
I recently bought a new 80 watt model that had the triangular head, similar to the Harbor Freight unit. It had no way to feed welding rod into it. All it's good for is heating up and melting a flat surface. The tip got soft and broke off the first time I used it. Some cheap alloy. fortunately was able to adapt the brass head from my old welder to the new iron. Plastic welders with the right tip seem to be hard to find.
RLZerr
RLZerr - 10 years ago
this isn't a whitewater kayak, nor any sealed compartments so a few drops splashing in the rod holders or past the simple foam covers isn't a concern. The entire seat area is wide open.
RLZerr
RLZerr - 10 years ago
that's an old aluminum curtain rod. It's holding the plastic piece in place with a clamp underneath while plastic welding.

You couldn't pay me to get out in that yak. Rod holders might as well be water conduits to help fill kayak and the high density foam so loosely covering those gaping holes!!! Oh no! LOL. But this guy is very skilled at working those welds and fixing some pretty gnarly looking holes so props there for sure. Informative, thank you.

I had the same question and googled a couple key words. It looks like the tip he's using, is a specifically designed plastic welding soldering iron tip. I looked up "soldering iron plastic welding tip" and my second result was a link to a harbor freight kit that looks almost like what the person in the video is using.
