Well I got bored and my canadian cheapness kicked in, and instead of paying $100+ for 3 8" aeros that Im gonna need for my next build. I decided to see what I could do to make my own.
Ive seen the DIY's using PVC and heating it up and forming it to shape, but I didnt want that. I opted to make mine out of sonotubes, plastic plates, fiberglass and bondo.
The total cost to me for all 3 ports was under $20 and only 2-3 hours of my time.
I started by going to home depot and getting a 8" 8' sonotube for $6.99 They sell a TON of sized, so bring a tape to measure when buying.
I then went to a few stores to find the "aero" lip. I was looking for a plate that had a big lip and got the one with the biggest radius they had.Ended up finding the perfect plate at the dollar store, that had a perfect shape and was the right diameter for the sonotube. Got 3 plates for $1
I cut the centers out of the plates, a bit smaller than the inner diameter of the sonotube, and I also cut the sonotube into 24" lenghts (I havent made the box yet, but I know they will need to be between 18-20", so I will cut them down when I build the box later.
And heres kinda the idea, with the tube placed on top of the plate
Then I planned on fiberglassing the plates onto the tubes, the problem is they sonotubes have a "waxy" outer shell, and I didnt know if that would affect fiberglassing, but I sanded it pretty rough before attaching the plates,but I needed to hold the plates in place so they didnt move while I glassed, you want them straight up and down obviously, so I centered the tubes on the plates and put a dab of hot glue in 5-6 spots, worked great.
All 3 done, ready for glassing
The glassing materials I used ( I used my 5 gallon drum of glass not that bondo stuff, just put it in there for the pic ) DONT forget to get some disposable gloves, fiberglass ***** when you get it on skin
