Cutting OLD Glass 101

[@GypsyHunter232UK]

My dad a Polish peasant farmer born in 1920 had an old diamond glass cutter he got from his dad so it must be at least 120 yrs old or older. I still use it almost daily and it still cuts like it was new. The tiny diamond 💎 is very small and is the best glass cutter I have used and has lasted out all the modern glass cutters I have used. Made in Poland and I'm third generation using it and will hand it down to my son and hopefully he will hand it down to his son and sons son son.

[@treyrische611]

What about HIS son?? Only 8 generations, shoddy polish craftsmanship... 🫤 😉

Just tried to cut glass today for the first time. I've been humbled. I have to say, you're nothing short of a wizard. Holy smokes. Free hand and just making it look absolutely easy. Maybe it didn't help I was also using old glass, but dang. You certainly have a well developed skill. Respect to ya.

[@christinecalka-et2hr]

Thanks, Roger. I learned a lot today from your tutorial and feel comfortable salvaging old glass for picture frames.

[@SharonClovistouch]

Thank you for using common sense language that folks can understand

[@Nezi_Ar]

This man is cutting straight lines freehandedly!

[@longhair-dontcare9983]

Thank you for a wonderful presentation. I'm glad that you did not edit out the unintentional breakage. I won't feel so bad when that happens to me.

[@bigstep9276]

The most informative glass cutting video ive seen so far

[@MikeNewland]

I reused some 40 year old glass not long ago. Glass I put in originally. Cut to smaller squares. Had no trouble. Unexpectedly.

[@pemtax557]

Hi Roger ... I learned a lot from you about not only glass, but vintage glass, and what to look for when anaylising it's potential to recover,. So useful and not necessarily "common sense" ... thanks so much for sharing your experience and talent for dealing with like circumstances. Cheers my friend ... dave

[@maggieandsydfathers8748]

Absolutely brilliant. So good to hear/see how it’s done by a really skilled professional who has the ability to pass on years of experience in an easy to follow way. Thank you! Regards, Syd Fathers

[@RW-Addictivlip]

Great to have a video that gives you the little points that have a massive impact. Thanks.

[@deansawich6250]

Thanks. I've been battling with old glass, and I did not realise that it has different characteristics than new glass. I'll try some new glass to see if it is my technique or the glass. 😊

[@garyfishel9612]

Thank you! I wasn't aware of cutting tempered glass. Was planning to re purpose storm door glass for display case shelves. Guess I'll leave it to the pros.

[@1lovesgreatness]

Admirable job. ..appreciate you, player.

[@charlesmurray1220]

You make it look easy. Thank you for the tips.

[@peterbarlow8912]

Spent may days doing this for customers who adamantly wanted to keep their old sash. We penetrating epoxied wood styles and rails. We rebuilt muntins with epoxy and 2 part wood fillers. The time and materials would often cost way more than a new sash. Cutting desired thready old glass was a crap shoot. Priming putty lands is important.

[@pauleyedwin6056]

Good video Roger, I just liked and subbed. I’m new to cutting glass and have several wood sashes needing new glass. I believe in purchasing the best tools that I can afford. What is the glass cutter you use at the restoration house. Thanks.

[@rogersshop]

TOYO, however a Red Devil will also do the job and they do last quite a while when used properly.

[@pauleyedwin6056]

@@rogersshop Thanks Roger.

[@scottvan1898]

I wish I had watched you video years ago at 10:35 to using the torch . Thanks !

[@UzumakiGarage]

Thanks for your sharing your expertise in this video. Is a glass in a jewellery shop display cabinet tempered glass? and not possible for an amateur to cut...

[@rogersshop]

Probably is tempered and that cannot be cut.

[@UzumakiGarage]

@@rogersshop ok thanks for the reply. Cheers

[@Dexter7723]

Excellent. Great explanation, clear and to the point, no yammering on and on and on. lol

[@1947froggy]

Great video, I need to cut a lantern pane from an old picture frame glass so trapezoid. Wish me luck. PS How to id tempered glass sheet if it's not in a frame/door/window?

[@rogersshop]

Tempered glass "usually" has an etching in a corner of the glass pane.

[@1947froggy]

@@rogersshop Thanks, I tried a couple & got it until the last "cut" Thin glass maybe 2mm maybe harder to do? I am going to try plexi glass. :)

[@rogersshop]

@@1947froggy Old glass can be a challenge and the older it is, the more difficult it becomes!

[@1947froggy]

@@rogersshop I don't think it's that old but really thin, thanks, any tips on plexiglass?

[@rogersshop]

@@1947froggy Use a scoring tool designed for it and make 2-3 passes before snapping over a hard surface like a table top edge.

[@stewartmcmanus3991]

Cutting old glass is a nightmare. I removed an entry door from an old golf club that had been in the West Australian sun for decades. The top lites were half inch thick. It was like trying to cut concrete !!! If you can get a Fletcher cutter, buy it, they're the best, Red Devils are second best.

[@josephno1347]

does it get harder in time like concrete does?

[@anunaki1975]

Very nice presentation Sir 👌🙏

[@lyonscultivars]

Unpredictable glass? Drawing the cutter off the edge cracked that pain bro.

[@1lovesgreatness]

Pane

[@MargaretPye-s7g]

I did the clear vinyl and then did a white sheet behind it, so that seems to work pretty well.

[@Jack-Surreal_Panes]

When measuring a 12" piece do you mark the 12" line and put the wheel on the line then adjust the straightedge to accommodate for the wheel to cutter edge?

[@rogersshop]

Yes, correct.

[@devineRenovationZ]

7:18 and I’m watching this video to learn how to cut glass over 100yrs old to salvage for smaller windows on the job 😅 I know while cleaning and glazing century old glass; Be very careful where and how you put pressure on it. All the bubbles and small hairline cracks will stretch from side to side very easily on some of them 🤦🏻‍♂️ (learned the hard way)

[@devineRenovationZ]

And do not by any means necessary believe that you’ll be able to salvage old glass either. Smaller cuts, about 75%of those break good after scouring. Long breaks.. big pieces..😅 I’m at like 25% right now. Even took a 4x3 pane to a glass company to see if they could cut down for me. No luck. Maybe 🤔 if cut with water (high pressure) instead it would be a better outcome🤷🏻‍♂️ Good luck!

[@margiedurrett8607]

Do you have any suggestions for cutting old thick store front glass??

[@rogersshop]

Same as cutting regular window glass, provided it is not tempered (will not work at all) or laminated. If laminated glass, you need to score both sides, lightly fracture on the score, then cut the laminate with a razor blade. Not as easy as it sounds........

[@Jim-yk9zw]

So the window frame you were holding looked just like the one I'm looking to put some glass in. My father in law was one of those dodgy DIY'ers that painted most of the windows in the house shut over the years and he didn't care personally bacause he likes the heat so opening a window wasn't a concern for him 🤦‍♂ But since I'm now doing some minor renovations and making these windows functional again is part of that task, I have to replace the glass I cracked trying to pry one open...

[@Dr_JimY]

Thanks for just enough stuff to get the job done and very little BS! BTW I noticed that you hold the glass cutter at a 60 degree angle...other videos show it held upside down...does it matter?

[@rogersshop]

No difference. I do it both ways.

[@docox27]

Great video

[@donny_bahama]

Do you do anything differently if you’re working with thick glass (1/4” - 3/8”)? Also, any tips on smoothing the edges?

[@rogersshop]

No, same process. To smooth the edges, there are rubbing bricks made for that purpose. You can also use a silicon carbide abrasive belt on a belt sander, but be CAREFUL!

[@donny_bahama]

@@rogersshop thank you!

[@dirkschilstra4942]

Hi, can you tell me what the numbers and fonts means on the cutter? (TC 10, TC 15) Thank you.

[@rogersshop]

Generally hone angle with TC-10the most popular for plain flat glass. TC-15 and TC-17 are usually used on seeded, textured, and stained glass. (I am not a glass expert, but did work for a glass company in my younger years)

[@dr.jamesnager1373]

Does it matter how you hold the cutter, and whether you push or pull?

[@rogersshop]

Not really. Done it both ways. Just don't go back over a score line.

[@richardvega2784]

What's the function of the ball at the end of the glass cutter? Also, what are the glass cutter notches used for?

[@rogersshop]

The ball at the end is used to strike the score on heavy glass to initiate the break (not for a novice!), The notches on the head are used to initiate the break on small width scores. The different sizes of the notches are for different thickness glass (also not for the novice)

[@capt.catfish-jd5fz]

About how long does the cutter last

[@rogersshop]

If not abused, years.

[@andyhamilton9459]

Removing old glazing is easier and probably safer with a steaming machine, like what’s used for removing wallpaper.

[@rogersshop]

That works too, just WAY slower

[@davidrountree9326]

You do not have to cut both sides of glass if you have a good glass cutter and have scored a good cut

[@rogersshop]

I don't unless it is laminated glass. In that case it is required (and a sharp razor blade)

[@MargaretPye-s7g]

You did electrical work?

[@rogersshop]

44 years. Now retired.

[@kareno8634]

Thanks! hope you gave that Frame to someone - Always a use. Love my Old Windows - "Crown" huh ? _hmm_ : { cheers!

[@mikelanglow-bi2sv]

Thank you

[@theq-1]

Everytime i score.. even hard the glass just won't break..no idea why. 3mm old greenhouse glass.

[@rogersshop]

Greenhouse glass is usually tempered. You can't cut tempered glass with a glass cutter.

[@DomingoLlanes-yq7me]

SIR you did not show video how to break the glass after you scourge it?

[@rogersshop]

Just 'snap' it by holding each side and giving a bit of a flex.

[@richardvega2784]

Thank you!

[@YoTambienFuiUnSerHumano]

👍🏻

[@jonnscott4858]

2 things wrong, pressing too hard and wiping edge with glove but the other stuff you showed was good. Passing on years of knowledge is great when that knowledge is correct but blind leading the blind on some stuff made my tutor laugh.

[@mrgrinch61]

hot to cut round edged

[@darktruth95]

The oil is make the cutter slide on that glass and your not hearing a thing.

[@rogersshop]

Scoring wheel is not sliding. It rotates. Maybe you can't hear it, but I can. Light oil makes a scoring wheel last a lot longer and some tools actually have an oil tank built in.

[@roswel03381]

your using to much pressure on your cutter.

[@rickygibson3754]

not a dame thing to do with old glass you are edge running to hard and hitting the glass with the cutter frame because you are pushing to hard when you come off the glass ENOUGH SEEN I could teach you how to cut the right way

[@antoniooreguy6478]

You handell badly the glass that why brekes Be Cerfull nex time

talk too much
