Bulkhead rant.

[Bugeater281]

I need to rant. And I’m curious if anyone else has noticed this.

Why can’t bulkheads be more consistent in sizing. Why is it for a bulkhead that needs a hole of 2.2 in you either have to use a 2.5in hole saw bit or some random metric glass cutter. Maybe there’s a good reasoning. But I can’t think of one. I’m sure there’s options out there that are more expensive. And maybe it’s my fault for deciding to drill an acrylic tank. But I swear I can move the bulkhead 1/8in either direction. Granted the only hole saws bit locally that’s weren’t crazy expensive were your standard American sizes.

Curious if anyone else has had issues with this? Ironically the 6 holes I cut in the bottom for my closed loop have zero leaks. While the one overflow bulkhead I can’t seem to get centered well enough to seal right. And bulkheads are from brs, so I assume they are at least mid range quality.

So rant over. Time to go drain the overflow again and see if I can get it to seal this time.

The hole may have been cut for a schedule 80 pvc bulkhead, they are larger in diamater than the black ones.
I prefer the sc 80 over abs bulkheads. Abs are prone to craking if over tightened, pbc are not.
