I'm no expert but I read a good amount. It looks like you used a template, so that's good. Glass will chip like that, it just looks like you had a large chip. Overall it doesn't look that bad to me, just the one part seems a little larger of a chip.

I used a corded drill that has a side handle, and is very stable to drill straight. I've read that clamping another piece of glass to the back side will minimize chipping at the end of the cut. Don't apply much pressure and let the tool grind out the glass slowly, especially slow and delicate near the end of the cut.

I set my hose sprayer to a trickle spray that kept constant cool water on the cutting surface. Also the water flow seemed to wash away the glass particles.

What diamond bit did you use? I will need to pick one up soon.

Also not to troll on this but has anyone attempted to drill a larger hole where a smaller hole is? I have 2 that I want to increase the size or just cover completely.

These are the bits

And to drill a larger hole, you'll probably need a jig like this

All of which can be purchased on amazon.

Is that similar to what the drill press types? I will need to drill regardless. I just have 2 smaller holes on the bottom back that were previously used for some kind of quick drain...cant find bulkheads that will fit. Might just get some glass and silicone over them.

You can use the bits with either a drill press or handhend, I used both drilling my tank, handheld for the larger ones and press for the small one.

I've done quite a few for people. Most will go with drains too small and want to increase later. Just let the drill do the work, don't press down hard.



As far as bit size, go to BRS and look on the bit page. They're really good about telling you what size bit works with their bulkheads.

I wouldn't do that unless the tank is small. Just drill them out and put a bulkhead and plug. I've done slip x slip and thread x thread and both held a good water tight seal. I use silicone too though.

^^^That's exactly what I did.

Be careful buying bits on Amazon if your looking there. There's quite a few, and I accidentally bought one that shipped from China. I just picked one that looked the best, and decent price. It took 3 weeks to get, but I wasn't in hurry anyway.

Does the wood template work the same as the press or handheld?

These are the small holes drilled at the bottom as is. Without taking the plugs out. Looks like the holes are probably .5 inch. They are too close to the frame to even go bigger. Any suggestions?? I deff don't want to keep these plugs in as a long term solution. I still need to drill for the overflow.

I like it better than everything. Just position it and tape so it doesn't move. I have a template I made that has several holes and sizes. I start all my holes and then move it. It's easier for me because I drill a lot of tanks at different locations. It's mobile and quick.
