Contributor matt griffin and i were hanging out and he started enthusiastically telling me about a technique for friction welding plastic that he d just discovered.
Diy plastic welding rods.
Heat the end of the rod like you normally would in welding to attach it to a clean spot on the plastic.
He had learned about it in a video from the awesome fran blanche she of frantone guitar pedals fame.
A rod testing kit comes with all sorts of different plastic welding rods.
Use the degreaser and spray it onto the plastic.
My grandparents have some ocean kayaks they use on a river and the bottoms.
In this case it is a polypropilene mix called epdm it has nothing common with abs.
I still haven t tried the technique myself with my dremel tool but it couldn t be easier.
You have to cut a v groove from the front having some support from the backside to hold the loose sides level and you have to heat up the filler rod not the material you are welding.
Several years ago make.
To use the test try to pick a rod that most closely resembles the plastic.
However all the diy welders i ve seen assume that you have access to welding rod.
And a welding rod which must be made of the same plastic you want to repair.
The best hdpe welding rod i ve found so far is the tear away ring that comes on 5 gallon paint and drywall mud buckets.
