06RTCharger Posted May 24, 2017 Author Report Share Posted May 24, 2017 First attempt cutting the tube, failed. Actually first tired to cut it at work on a band saw and almost lost a hand lol that shit bit HARD and slammed the tube and my hand. Scared the shit outta me. But went and got a handsaw that said it was made to cut plastic, fail Link to comment Share on other sites More sharing options...
06RTCharger Posted May 24, 2017 Author Report Share Posted May 24, 2017 So that saw didnt work, asked the forum for help and they suggested a hack saw with fine teeth (high tpi). Went to lowes and got one. Used a straight edge to draw a my cut line figuring that just a straight line would work...NOPE. Lol apparently a tube cut at an angle doesnt creat a straight line when layed out flat(pic at end), i think its called an ellipse? Idk. So before i cut i got down into some geometry and worked it out, thats the first pic, showing the graph i used to get my ellipse shape for my "truncated cylinder" (science name for a angle cut tube lol). Taped that shaped to the tube and drew my cut line, you can see the thin line thats my first cutline using a straight edge of thin cardboard. See how the thicker cutline of the ellpise curves more. Worked out perfect, and the hacksaw with a 32tpi blade worked great too. Link to comment Share on other sites More sharing options...
06RTCharger Posted May 24, 2017 Author Report Share Posted May 24, 2017 Since HDPE plastic is very difficult to bond, i did some searching and found Tap Plastics site. They make a polyweld adhesive that is made for hdpe bonding. It requires heat treating the areas that will be bonded together with the yellow flame section of a torch. Very simple. Just wave it over the area a few times with the low heat flame and to be sure its treated just put a lil water on the area and if it DOESNT bead up then its good. If the water tries to bead up then keep running the flame over it a few more times. After that just apply the adhesive and DO NOT clamp together. The adhesive is most strong when there is a very small gap, the size of the thickness of a sheet of copy paper. You can actually use a couple strips of copy paper and lay it across sections of the adhesive and then press down firmly and ur good. Curing time is 24-48 hours. Also whats good is the work time is very generous so u dont have to worry about rushing before it hardens. Link to comment Share on other sites More sharing options...
06RTCharger Posted May 24, 2017 Author Report Share Posted May 24, 2017 Successful bond of HDPE to Polycarbonate. Im glad the adhesive required some gap because the tubes edges werent completly straight. I did alot of sanding down to get it as straight and flush as i could but it still wasnt perfect. But i figured this adhesive would still work well and it has. Link to comment Share on other sites More sharing options...

06RTCharger Posted May 24, 2017 Author Report Share Posted May 24, 2017 Drew a cutline on the plates using the tube and cut it out with a dremel, which worked ok. Didnt wanna get the router out. Mounted the plates on the door. Mounted the speaker onto the ring/tube and test fited it onto my door using the guide lines i drew by just lining up the black lines on the ring/tube with the gray lines on the plate. Last pic shows the speaker basket hitting the sheet metal. The magnet had lots of room so depth wasnt an issue. So i drew a cutline with the plates mounted.

06RTCharger Posted May 24, 2017 Author Report Share Posted May 24, 2017 Used my dremel again with a cut off wheel for metal. Tried the "thin metal" blade first and it broke. The regular one worked perfect, but i wore the first one out and used another. Test fit the speakers again and it fit perfect. So i sanded the cut edges on the doors and cleaned of any dust then used some touchup paint and coated the edges. Also coated around the rivnut holes.
