not a tank. i just need to drill about five 3/8" holes in 1/2 " glass. any advice? slow/fast drill? do i need a special kind of bit?
Hey Paul, first I’m guessing it’s not a tempered glass? You will need a glass hole diamond drill bit. I have 3/4", 1", 1 1/2" bit if you need those. I use plumber putty for water containment so that it lubricate the bit. I also use a cardboard cut out as a template to the size of the bit/hole to start the hole. Drill slow and don’t put too much pressure. Let the weight of the drill, drill for you. All else fail, stop by my house I’ll do it for you.

thnx A. i need to therefore get a bit the right size, prolly 1/4-3/8, and get the glass also.
No problem Paul. You get the bit and just let me know.
What are you drilling? swiss cheese glass sculpture? :

trying to replace a plexiglass waterfall on my pond. gotta attach it to a plastic weir. ya know that an old man with a drill in his hand can be dangerous.
why not just use another piece of acrylic? what size and shape? i got some scrap around here. and glue. I guess the original one broke?
I figured he was crafting up a Mega Hookah ::

ken i’d take you up on that offer, if you have a piece about 3/8 thick, 30X12. i’d buy a piece at lowes but it’s $54.
john, no hookahs for me, but that sounds like a good idea for younger folks, like you.
I guess this is to replace the water fall edge. you must be pumping 3000GPH over the falls. it takes about 100 GPH per inch of spill edge to keep a smooth falls. i have a piece of 1/4 acrylic 30" x 10 1/2".
you could also try epoxy over wood for an edge. completely encase it in epoxy. like a boat hull.
ken, i can’t use it at 1/4". i am currently using 2 of them glued together, making 1/4 and 10 1/2 just wouldn’t be long enough to avloid the rocks where the watr enters the pond. i have a lotta splash at 10" and def’ly need 12" or so. i’m putting out prolly more than 3k an hour, since i can divert and still have a decent falls
thanks though, i really was hoping
ok, hows about some poly prop.
or cutting board
or any other acrylic or PVC material they have here if you need a bigger size and thickness.
I would just encapsulate some good, weatherproof plywood with epoxy and be done. like i said, thats how we make boats and fish tanks.
or another idea, i have some left over scraps of that resin packed rustic siding plywood from HD. i built my storage shed with it. its strong and solid with resin. coat with epoxy and its good.
lots of things you can do.

And exactly where in one’s life woudl one pick up this kind of information??
Well Craig, you could do some volumetric/flow rate calculations to maintain a 1/4 inch laminar flow of water over an edge, compensating for the acceleration of gravity.
or you could look up the specs on pond spillway stats, they tell you how much flow per inch for their spill ways based on the above sorta calculations.
But mostly it’s
Alimentary, my good Watson. I just pulled it outta my ~~~!
