Hi All
So after debating between internal and external overflows, i finally decided
on an internal (after reading tons of forums and asking the guys at Bulk Reef).
I could not find one pre-made that i liked so i decided to make my own:
I already had a 25 x 40 peice of black acrylic, so i made the measurements
for a floating center mount overflow: 20"x3"x5"

I was going to do a regular 3 sided overflow glued at right angles but decided to
try a more pro look by heating the acrylic and then molding it.

Next i cut and glued the bottom to the overflow:

The next step was to cut the drain holes for the water to flow from the tank.
Again i was going to go with the regular square cut but decided to try the factory look
with the holes recessed about 1/4" from the top.
This was a bit tricky as i had to use a router which is not my favorite power tool, i made a
few ooopsie's but got there in the end.

OK, i drilled the tank last night

The drill guide i have is a bit flimsy but it's good for starting the hole,
i then switch to handheld which gives me more control and feel for
depth.

Using plumbers putty to create a well for coolant is a good idea but
it also makes for a messy work area.
Each hole took about 2 min (Glass 1/2" thick)
The main thing when drilling glass is GO SLOW and of course a steady
hand helps.

Bulkheads installed on the 2 drains coming from the internal overflow.
Question/Poll?
What do you guys think, 1 return hole or 2?
Done! Floating Center Internal Overflow with 2 Drains and 2 Returns at either end...
