Homemade Super-Neo Woofer: THE CHEVELLE RESTORATION IS DONE, dampener recommendations??

Belt Sander ftw. Do you ever measure stuff? A micrometer could go a long ways towards preventing similar snafus in the future.

Do I what? No, don't think so. Could you teach me? I'm only trying to build. a. subwoofer. from. nothing. Of course I didn't measure. Who would need measurements on such a design-dependent performance based on electromagnetic and physical calculations? That sounds like a foolish move......pfft measurements are for people who want accuracy, and nerds. #yolo #nomeasurementlife

he cut the pcv in half, so he cant measure it easily unfortunately.

get a rough wood working or aluminum file. Just have to clean the file out every now and then. And i'd find something to test with before trying to put the plate on because getting the pcv out will be a bitch if it gets pinched, you dont want to use heat near the motor.

edit

You could also use a grinder, but you have to be careful as it will eat the pcv away in a hurry and be very uneven if you dont practice a bit first. I used to be pretty good at shaping pcv on a grinder

I really don't care if it's uneven at the bottom as long as it can allow the plate to get over and still slide out after. And you'd be surprised at how resilient this plastic is

P.S to everyone who thinks it's PVC, it's actually ABS, hadn't noticed until yesterday. I never use ABS and we hardly use it for plumbing work anymore but I don't know if that changes anything here. Feels less compressible than PVC.

WHY DO I EVEN TYPE IT IN THE ORIGINAL POST???

I ALREADY TRIED BELT SANDING WITH 36 GRIT, AND IT DID NOTHING.

HIT IT WITH CALIPERS AND IT DIDN'T EVEN REMOVE MORE THAN 0.2 INCHES AFTER 20 MINUTES.

I'll hit it with my random orb sander and hope for something better, but I'm highly skeptic.

Heat/stretch with a heat gun? Similar idea to how they make fiber optic cables

I'm afraid it might bend/deform it and have fitment issues.

[SnowDrifter]

Do you have access to a lathe? You could shave some off with that

[Krakin]

Could try and find a local fabricating/cabinet shop and see if they have a tool that will help.

If nothing you might try going PVC, my belt sander does fast work of the cell core.

You need to use a grinder or a file on ABS I think.

You could mount the ABS in a lathe or drill press and grind it while it spins.. just dont spin it too fast lol.

[Jessica]

you need to soak it in cider.

but seriously, try putting the abs in the freezer for a couple hours and the top plate in the oven at about 150f. 150f should be safe for it right? That might give you enough wiggle room if you work fast. But you need to get it together and pull the abs out in short time'

[Rockford96]

Like stevil said a grinder with practice sounds like the best bet to me even a die grinder (unsure of spelling) Hell even a drill with a wire wheel or grinding stone would work wonders

Edit micrometer is a good investment but imho slide caliber is better

Micrometer > slide caliper any day of the week

micrometers are the bomb lol takes a lil learnin but they are great!

[STEvil]

heat wont hurt the top plate, its just steel, but heating it and cooling the abs wont achieve anything.

If we were seating a large planetary bearing race which only needs a couple thousandths of an inch to set then heating would be ok..
