here's an easy way to flare a square or rectangular port
pvc pipe and some silicone with tape to hold it together


and the final product, just add some resin for strength, smoothness and filling in imperfections

 

nice flare.....does this mean your coming out?

 

lol na, I was just bored at my shop
did it surprisingly quick, maybe an hour tops

 

I will see you in kingston buddy. C'mon out.

 

Is that a three inch PVC pipe cut in half, and then 45'd on each end?

 

4" and yes a 45 would be my guess. But Les will confirm soon enough.

 

and it looks to be cut into 1/4s lengthwise.

 

note taking material over here

 

that is correct
4" pipe in quarters and 45's on the ends

 

nice port buddy
