How To Cut Glass 

Brief, simple and straight to the point. Scoring both sides is a game changer, worked an absolute treat and using half of a wooden clothes peg. Thanks a million.

Cutting new glass is one thing. Cutting old is another. Today I had to cut down 8 panes of 50 year old 4mm greenhouse glass. Really rippled stuff. I've never cut glass before today. 2 neighbours (one a builder) told me it couldn't be done, that it would shatter, splinter or cut jagged. I wasn't looking forward to it. I have a type of motor neurone disease. I have no strength in my fingers/hands/wrists and my hands shake like anything. I had to develop a way of holding the cutter with both hands, one hand controlling the angle, the other controlling the scoring pressure while keeping the cutter tight against my straight edge. Then I used your double scoring method (but snapped the glass off the edge of my bench rather than using your lollipop stick trick). I used 2 other tips I picked up from other youtubers. I oiled my cutter first and ran it lightly across my intended cut line without scoring. It leaves a neat trail of cutting oil where you're going to score. After scoring top and bottom I wetted both score lines with water before snapping off. I believe it stops the scores from 'healing'. You know what I ended up with? 8 perfectly cut pieces of glass from 8 panes of glass. 100% success rate. Zero breakages. To say I am amazed & ecstatic is the understatement of the year. A million thanks for your video.

I worked for a stained glass window company in Edmonton, Alberta, and learned how to cut curves in hammered and patterned glass. Now I can hardly cut a straight line in flat glass but this tip to cut both sides is just what I need for a job this Summer. Thank you.

I am about to cut a glass next week..this is the best video I've ever seen on the subject. Thanks 🙂

Good job as usual! I used to cut glass in my family's hardware store and scoring the glass on one side "usually" worked but not always. We also had a brake, like a metal bending brake and sometimes the glass still broke incorrectly. I had never heard of scoring on both sides until now - that would have saved my dad quite a few sheets of messed up glass.

Can’t thank enough for you to upload this video.I never done this and broke many glasses before watching this. Finally managed to fix all glasses for my green house. Many thanks again!!!

Thank you for sharing that - very useful and has taken the fear out of my potential first ever glass cutting exercise :-)

Thanks, very useful indeed, enabled me to cut some thicker glass in an emergency, never thought of cutting both sides before!

Thank you. Very helpful. Making a score on each side and the small wooden stick. !

wow, just looked for some simple tutorial and here it is! Cut on both sides is new to my knowledge, but definitely I will use on my first glass cut in 45 years so sounds it should go fail safe! Thank you!..

Once again excellent info from John!

That was definitely an informative video!! I have never cut on both sides and (like you before knowing) had limited to bad success getting a clean cut from short off cuts. I will be using the technique next time I need to cut glass. Thanks John!

Very nice video. Off to try it again on some thin old salvage glass. Cutting on both sides seems a very good addition.

Great video. I've been struggling all day to get a straight cut. Thanks for the tips 👍🏻

Thanks, gave me good information without spending two minutes telling me to "like and subscribe" - so I did!

Never been good at cutting glass, actually looked this video up again for some tips. Thanks John,

Just bought a cutter. Works great thanks for the advice 👍

Wow, wonderful tips! Thank you, I'll remember these for sure :)

That was great Jon. I have some spare glass from old shelves that I want to repurpose for new shelves and this gave me the courage to give it a try. Thank you for sharing all your talent. I really enjoy your videos. Like & Subscribe. Eric central Florida

Great video. I have had limited success in cutting glass, so far I am 1-7 attempts. And a few times I tried to score on both sides, but due to my complete ineptness I have a really difficult time in scoring it exactly on both sides, and trying to keep the straight edge,....well,...straight during cutting is another challenge. I recently gave up trying to do it myself and took a piece of glass to my local glass shop (they have been in business for almost 30 years), and what they told me was counter to most of the advice in all these youtube video's. I was told you need to press quite hard (my glass was relatively thick), where as most of the video say to not press very hard at all. Thanks for sharing your tips, off to destroy a few more pieces of glass right now!!

Cutting on both sides saved me :) It works. Thank you !

Thanks for taking time from your work to help.

Thanks for sharing this video I did the same thing you did cut both sides work perfect saved me a lot of money

that's increasable! I never knew it was that easy to cut glass so I always stayed away from projects that called for it. great stuff man!

Very good. Best I have seen.

saw a couple of vids, this was the most helpful

Your garden is amazing!!!

Thank you so much, you literally saved a life. I love your t shirt btw.

Here's a pair of simple tricks I've learned to help when cutting glass. The stick I used is about 1/8" thick. One of those big match sticks works well. Cutting on a clean, flat surface helps.

Tanx Jon for your insight.hitherto, I have been finding it difficult to cut little strips clean and without breaking.

Beautiful...never new it was that easy!

Straight to the point, I love it, thanks!

Thanks for the short and informative lesson

Glad to see there were no outtakes on this one, John. ;-) I've also found cheap scribes to be the best tools but had never thought to cut from both sides to get a cleaner cut. I've tried using those wheels you can buy but with only around 60% success.

Thank you so much! You’ve helped a gal very much today! ❤❤❤

Great job of showing good technique

Great video. Short & to the point

Have never seen this way before! Thank you for taking the time and sharing your secrets of successful glass cutting. How long is the cutting wheel good for from your experience? 10 cuts, 20 cuts? Thanks again!

A big thanks for another helpful tip.

That was a great tutorial bud, thanks for sharing your method.

Great video and great tips. Thanks very much!

I LOVE the wood thing!! Thank you

That trick of putting the wood under the score mark and pressing down is brilliant!

For perfect cut...use some oil, i am using petrolium (fuel for lantern) cut away from you..les chance to move straight edge..and after cut hit the line with cutter :). Like your videos and ideas. Greetings from Ireland

I may have to cut some glass soon - you give me the confidence to try it!

so glad I watched this, my memory is as as bad as I am old. 😁 happy new year

Thank you, Cutting one or two inches was complicated, but mo more thank to this video demonstration...

The cutting sound so satisfying

Great! You made it clear and simple.

Wow never knew that, thanks, well done video editing as well

Loving the vintage smashing pumpkins shirt! Thanks for the info!

Having to cut real glass, I found out my stained glass technique was not going to cut it. Thank you for the concise explanation about how to cut thicker glass. Scoring on both sides made all the difference!

Brilliant! Thanks for sharing the tip.

Thanks for sharing your knowledge- very helpful,

Yeah, that scoring on both sides is the bomb. Thanks!

Very nice, thanks for sharing.

Great tips, thank you for posting

Thanks John you are the master!

My dad was a Glazer, I am a Glazer. Been doing it for 15 years. You never have to cut both sides unless the glass is thicker than 3/8 of an inch or if it’s laminated. Otherwise a pretty damn good tutorial man

Thanks for this. Will try this method shortly.

Dude!! You're such a lifesaver. I need glass cut but I don't want to buy a glass cutter.

This is awesome man, thanks for the simple video. I'm making a custom sized aquarium, wish me luck.

Great tip I can't wait to try it

Usefull video indeed, thanks a lot. Now I belive I can do it!

Thanks for your video. I have to cut some glass for some windows . Going to use some glass from large sliding glass doors. 👍🏽

Wow!! Great tip.

Good video, keep it up!

your display of glassman'sskills , craft and touch @2:05 was most impressive

This video was the easiest one i seen damn it looks soo easy

Thank you for your brilliant demonstration .now 👍👍👍

Very helpful video, thanks men.

good tips man I'm going to be cutting some now

Thanks for the tips, good video!

Nice video, thank you. Learned something new, cut on both sides :D Greetings from germany.

Thanks, didn't know you could cut glass but now I know and will give it ago 😎

Thanks so much for this video. Helped me a lot. It helps if I was holding the cutter the correct way and this video showed me that too’ hahah

short and sweet, thank you

Clean it is, I will try this . Thanks

Thank you for what I hope will be the start of a base to work when cutting glass, as my score rate has been pretty awful to date Mr Spence Eng

That cut @ 3:00 was amazing! Great video!

Fantastic tip - thank you.

thanks for the video.did not know that I should score both sides.

Thanks so much I'm going to try this.

Thankyou for your help.it is very helpful.

Great video thanks

Did not know this thanks John.

How is it I find it so extremely satisfying to watch successful glass cuts?

Thanks for your help, sir!

THANKS. I Never thought to cut both sides.

Thank you for this video.

Used this tutorial to cut glass for the first time. It really screwed up on me the first few attempts, but I found it works better for me if I use 2 pieces of wood inserted under both ends of the cut. Thanks for the video! It was super helpful!

At the time of the corona virus when intellectual idiots like me have more time, it is an opportune moment to learn a few practical things. Thank you so much for these tips! I cant start at the momenet because all shops are shut down because of the epidemic but when I can get hold of a glass cutter and piece of plywood and cardboard Ill give it a try. I need to cut some panes for pictures. So good that you tube gives people the opportunity to learn practical things like this.

Great video

Scoring on both sides! Great tip...

Greetings from Blackburn, England UK. What a clear succinct video. Thanks for taking the time to record this. I couldn't have hoped to see a better description on how to cut glass. This is just what I needed as I'm about to cut a glass pane to size for an internal transom window.

Thanks. My grandfather showed me a way - he scored one side then dribbled alcohol on the scratch and lit it. Tink!

I loved this

Great tutorial. Somehow I still managed to mess it up. I measured my lines several times on both sides, scored the first side, flipped it, scored the second side. Got my little piece of wood under the cut line and pressed down on both sides. The crack started from the bottom, went about half way up, I started to get excited that it was working, then the crack took a hard left, off my score line!

Thanks, very very simple methods.

Thank you so much, sir ❤ Your Video helped me a lot ❤
