cut a hole in glass for a cat or dog door

only video found so far to create a round hole rather than a round piece of glass!! will try that. very workmanlike and careful tute. great.

I am a glass cutter in New Zealand and i have never seen the inner circle before, make sense. Thanks for sharing .

Great instructional video, mate! Thanks to you, I was able to cut holes into two sheets of glass for a double glassed window to install a cat door! Greetings from Germany!

I like how you gave two metric measurements... 25mm or 2.5cm. Take that America! And using an otto bin as a tool brought an aussie tear of pride to my eye.

I have attempted many hole cuts and failed before I discovered your video. Great work. And I see why you need to turn over and 'break the seal' directly after scoring the circle. It stops any cris cross scores following through past the circle score line. Circle cuts are incredibly hard to master and you have made it look so easy.

I have just tried to cut glas for the first time and understand now, that it is more complicated than you think. It's really fascinating how glass reacts to disturbances in the structure.

Great video, very clear. I like the 2nd ring technique.

Thank You! I've been looking for round cuts for a little DIY project. This was super helpful :)

A fishing Rod, a Vt commodore and an Aussie flag, I think this guy is Australian.

yes some neat tricks. I am Glazier myself it's nice to see some new tricks I will give that one a shot. there is a lot of people posting videos on how to cut glass and they say they have lots of videos on how to glass that are done by people that don't know what they are doing but this is very clever

OK! Genius!!! :) I have been looking all over YouTube for this answer! Thank you:) Make a million videos! You did such an excellent job on this one, I can hardly wait to watch the rest of them. I love your accent that you know you don't have;) LOL! BOP

Best tutorial, thanks a lot!

Great vid! Thanks so much.

Great video only constructive critism is I wouldn't say push hard . Unless a person knows what pressures you can and can't use on glass can make the glass crack if you push hard. My advice is whay your doing is making the glass running. Basically put your thumbs literally on the glass cut and slight press down and applying pressure slowly and then the cut will crack and then you can simply start make the cut run. As you press down slightly the cut starts to run in front of you and you can follow it around to it meets the start point. You don't have to push hard jist slight push and apply pressure and you will safely keep the cut from breaking. Don't press hard as to much pressure you can break it

Brilliant work, nicely explained. Thanks much.

I've always wondered how this was done. Good vid.

That was brilliant.... I loved it

great video thank you. We have only one glazier in town that will do it and it seems to be a mission for them and cant do it for weeks, Lame. Glad I watched this now I know to do two circles which is a great idea. Thank you again

thanks for sharing mate, works even with after a bevy ;)

Great! Good technique, i'll make use of it. Thanks
