@@leiwa100 I am an Avid watcher of Ageing Wheels. I just like seeing Robert's other projects and his cool thing reviews on Under Dunn. I accept that it's a secondary "as it comes" channel, which is why I'm very excited.
Well, as a former glass technician, i can provide a bit of insight as to why the glass didn't break properly on the tablesaw scored line. It's similar to the concept of sandpaper. When you use a coarse grit sandpaper, you get a coarse surface. That diamond cutter blade is acting like a coarse sandpaper, leaving a much wider groove. When you score the glass manually, you are defining a much thinner line, which produces the least amount of fracture points. Glass will always take the path of least resistance when breaking. When using the tablesaw blade, you are making tons of tiny scrapes and grooves along the score line, which allows the glass to fracture in way more directions. Glass and the laws of entropy are very intertwined.
I was guessing wobble, too. No matter how much you tighten the blade to the arbor, it will vibrate a little. I know this because for fun I measured a new saw blade one time and got 0.118" across one tooth, but when I used it, my kerf was exactly 0.125". I'd be willing to bet that the blade wobbling back and forth just that little bit would be enough to create a lot of places for the glass to fracture, as opposed to a nice crisp line that is done with a glass cutter.
the blade doesn't score the glass it makes slightly thinner glass. a scored piece of glass concentrates force down that line. the slightly thinner glass is just slightly weaker glass that doesn't concentrate force along the line.
The scoring with the tile blade probably didn't work because the energy in the crack wants to follow the crack line but the sawblade is almost like sand paper, creating many tracks for the crack to travel along, none of them straight
Why I love this channel... he embraces errors and mistakes openly, he *is* one of us, he also has a shop like most of us... not full of expensive gifted tools in exchange for endorsements.
Oh my gosh! From the thumbnail I thought this was going to be a video about purchasing cheap lanterns from home goods or Ross or something like that and making them look so much better. But you went all out, brother! Please have a marvelous, safe, and joyful holiday and New Year. 💚☺️👍
6:21 so fun fact, when scoring glass, the roller on the small wheel creates tiny stress fractures in the glass allowing it to break evenly as it breaks along the stress lines, now with the saw these stress fractures don't form because there is actual material REMOVAL. The material isnt removed as much with the scoring balde. Boom
Yeay! He actually made it all! I thought it would be some kind of cnc-copy-laser-cut-thingy that most other youtube-wood working shops has evolved (degraded) into. Good work!!!
On the mitred edges for the roofs, try gently pressing a pencil or the round shaft of a screwdriver to round of the edges slightly. It's a trick a trim carpenter showed me quite a few years ago to hide imperfect mitres.
My favourite technique for mitres is to burnish the edges (after glueing) with the round shaft of a screwdriver or similar tool. Basically mushes the fibres together and closes up a slightly gappy joint.
2:58 I saw the push stick and got unreasonably excited; i recently stumbled across Wesley Treat's channel and have been binging it like crazy; i love discovering when various makers I watch know each other! And you two share some highly enjoyable editing quirks.
The glass cutter's little wheel is nice and sharp, the diamond blade while deeper is quite blunt. You need the sharpness to cleanly propogate the crack.
Misss these woodworking videos. The car vids have entertained my Dunn fix for the time but the woodworking is what brought me in. Nice work. Look forward to more...hopefully.
Great to see you here again. It was a good build. I built a four foot pyramid for a museum exhibit. There was a bit of harsh language during that build.
Your slice-supercuts (like 3:00) are so pristine, they must be a bitch to edit, but it's worth the wait. Combine that with the lack of jumpcuts in your spoken deliveries and it's just a chef's kiss. I found this channel before Aging Wheels, it's always a treat!
Hell yeah, a new vid. Always great to see you back in the wood shop, Robert. Hopefully it's still a joyful hobby and not a chore to get sawdusty again.
Glad to have you back! Not that you've actually been anywhere (or have you? I have no idea) I do watch your other channel but I'm not really into cars, so I'm only watching for your wit and charm and the "car stuff" is in one👂and out the other! Brum brum!!
Regarding the glass cutting confusion, if you were to look at the cuts made by the diamond wheel vs. the glass cutting wheel under extreme magnification, you would see that the bottom of the diamond wheel cut would be a lot more rounded than that of the glass cutting wheel. It is the sharpness of the score that cause the stress concentration along the score line when you snap the glass, so even though glass cutting score is shallower than the diamond cut, when snapping, its sharper cut does a much better job of concentrating all the stress exactly along the score and thus resulting in a much better cut. Regarding the lanterns, they came out great.
Very happy to see a new upload on the channel, it was a very nice gift indeed! Hope to see more projects on here in the future. Here's to you and yours having a safe, happy, and healthy 2025. From us hillbillies in the backwoods of WV, Merry Christmas Robert!
4:37 you clearly wanted to make some sidetables and got the measurements slightly wrong, so now you are pretending that you always wanted to turn them into lanterns. can't fool me though.
Hey Rob, just coming here to say, Thanks for helping me feel worse about my project creep 🤣. Only had some rocksliders on the go for like 8 months, and a turbo kit on the go for over a year 😅. You eventually get everything done though, other than the bus project 🫣, so i have faith i’ll get to them eventually. Anyhoo. Thanks for helping me be more motivated haha
I love this project, on the weak joints on the top and bottom cross rails something I've done with success that seems to work well is put a small tenon the size of the glass grove on the vertical pieces. I've not destructively tested it so no idea how strong it actually is but I used this on a door for a mechanical clock face which gets opened all the time to wind the mechanism and it's still rock solid so maybe an idea for next time.
I really do appreciate it when you try to problem solve something faster and are stumped and do it the slower way anyway. The amount of times I've had similar moments when on paper something should have worked and didn't, it is very cathartic to see others do something similar. Happy New Year!
Christmas came a day late! Those came out great too, love the idea of finding cheap plastic junk and making it something nice. Also see you upgraded your tablesaw at some point :o
Scoring the glass is intended to send tiny cracks through the pane. Etching a line into the surface doesn't do the same thing. This is just a guess, but using a blade that causes more damage might achieve the desired result.
I was thinking about this channel from your last video with the 100K Electric car mileage.....oh boy, I am happy to see another video on Under Dunn. Happy holiday. Mr. Robert.
The cutting wheel makes micro stress points along the glass. When it snaps, the crack follows the weak points (the scour line). I think you could cut the glass on the table saw, but you have to do it VERY VERY slowly, or with multiple cuts, removing 1 1/16 of an inch depth at a time.
I worked for a window manufacturer for a couple of years cutting glass.It's really easy me, perigular glass.You can use a chainsaw hammer or a glass cutter at all works the same. I would suggest you go to a small glass shop and give me a hundred bucks to stand and watch some for a day or a couple of hours
Last video was over a year ago, I had given up hope on more Under Dunn videos! Time to binge the whole channel backlog again!
Aging Wheels is Robert's main channel. I do not necessarily care about cars but enjoy his video style so am following that channel too.

I too was surprised by the return, I thought he'd packed it in 🤔🫣
Me too

@@jesusnthedaisychain Most blades have the teeth offset side to side so the kerf is cut wider than the main body of the blade and doesn't rub.
Sadly, that makes a whole lot of sense! Geez. Never would of thought of that...
the blade doesn't score the glass it makes slightly thinner glass. a scored piece of glass concentrates force down that line. the slightly thinner glass is just slightly weaker glass that doesn't concentrate force along the line.
A new Under Dunn video is an amazing Christmas present!
The scoring with the tile blade probably didn't work because the energy in the crack wants to follow the crack line but the sawblade is almost like sand paper, creating many tracks for the crack to travel along, none of them straight
I suppose if he'd done multiple small passes with the diamond blade it might have eventually cut through without instantly cracking?
That, and they do make glass cutting blades for table saws.
I have missed your editing on this channel. Love your other channel, but I have to stop everything to watch when you post here. :)
It's the best!
Oh, how I have missed your woodworking videos… Welcome back! The world needs more of your content. Please make more. And Merry Christmas!

Merry Christmas Robert.
It’s a Christmas miracle. 2 Robert videos in the same week.
Best day ever!!
Excellent video. It was good to see you doing some woodwork again. Merry Christmas!

So happy you're back woodworking on this channel. And you got a new table saw!
It’s like a Christmas Present 👍😀 to see the presents being made.
Lol the sci-fi gun wooden pusher thing.
Honestly upset you got rid of the home built saw, i had followed that project and built my own. Glad to see you back
6:25 I do appreciate the immediate closure to a question. (But I guess that explains why I never see stained glass people do that!)
Great to see you here again. It was a good build. I built a four foot pyramid for a museum exhibit. There was a bit of harsh language during that build.

Under Dunn is the channel where I originally found all of your content. I LOVE your woodworking stuff!
Keep up the great work!
i'm impressed these finished up without a major injury. very cool!
A new Under Dunn is a great gift. Merry Christmas, Robert!
Hell yeah, a new vid. Always great to see you back in the wood shop, Robert. Hopefully it's still a joyful hobby and not a chore to get sawdusty again.
Probably a simple thing to do, but your jump cut timelapses are *chef's kiss* fantastic
Glad to have you back!

Its better to have the glass loose and removable in those lanterns. atleast if they are for outdoor use. easier to clean
I doubt very much they are for outdoor use, they are decorative for the inside.
Glad to see you back, son. It's been a while.
I echo other comments here and am glad to see your comeback to woodworking videos. Merry Christmas and Happy New Year!
Glorious! Welcome back Under Dunn! Glad to have this channel once again
Bravo sir. Great artistry, great editing and loads of humour.
Oh God, I missed you here. It's great to watch another video of you doing woodwork!

A new Under Dunn video! It's a Christmas Miracle!
The saw editing is my absolute favorite thing that I subscribed to this channel for!
My patron gets me early access to your second channel too!!!! Happy Christmas.
Cool project. Did you finally have to upgrade your table saw? Thanks for sharing!!
A new Under Dunn video is a great holiday gift. Thank you.
It is good to see you back in the woodshop, you should do more of those.
Missed this channel! Good work on the lanterns!

RETURN OF THE KING

8:08 that prolonged shot made me laugh out loud :D
Great to see you making stuff again! Happy New Year.
Welcome back and thank you for the Christmas gift of your amazing videos and comedy
Filming and editing is awesome as always Robert!
Yes! New Under Dunn video! Glad to see you still enjoying the wood working!
Thank you Robert, happy whateverthenextholidayis to you, too.
So happy to see something come out on this channel! I like the other one a lot but this makes me very happy 😃
Merry Christmas! Love seeing a woodworking project and what a wonderful gift. ❤
It's nice to see you back in the wood shop!
glad your back, your videos are still fun, I see you no longer have the old craftsman table saw
I was wondering what happened to your woodshop! Good to see new content. Keep it coming.
Hey Rob, just coming here to say, Thanks for helping me feel worse about my project creep 🤣. Only had some rocksliders on the go for like 8 months, and a turbo kit on the go for over a year 😅.

Hooray, a woodworking video to round out the year! Those came out great, nothing like having parts line up perfectly on assembly
I wonder if the laser could have etched a score line into the glass, giving a clean cut. Probably not, but it'd have been an interesting failure.
YES! Missed this channel so much
Mmmmmmm. Lots 'O new tools. I was emotionally invested in the old table saw.
These will certainly brighten up the recipient's days!
Marry Christmas, Bob! Good to see you doing woodworking! I just got an Aging Wheels Xmas t-shirt, now I need an Under Dunn t-shirt too!
Merry Christmas, Robert.
Your videos are always the right mixture of funny and heartwarming.
I love this project, on the weak joints on the top and bottom cross rails something I've done with success that seems to work well is put a small tenon the size of the glass grove on the vertical pieces. I've not destructively tested it so no idea how strong it actually is but I used this on a door for a mechanical clock face which gets opened all the time to wind the mechanism and it's still rock solid so maybe an idea for next time.

those came out great! i hope the recipients love them!
Beautiful work, I hope your recipients like them!
OMG!! An Under Dunn video! This made my day! Loved the Wesley Treat push stick. I need to get one.
Christmas came a day late! Those came out great too, love the idea of finding cheap plastic junk and making it something nice. Also see you upgraded your tablesaw at some point :o
Nice to see you back on here. Missed you!
Missed you, buddy. Welcome back. We all hope there’s more to come.
I actually looked up your channel the other day to see why I hadn’t seen any new vids. Assumed you gave up. Glad to see you back
Very cool gifts, I hope they loved them. Also, thank you for the gift of more Under Dunn videos!
Yeah, I found your channels through this one, so I'm glad to see a new woodworking video.
4:39 - What cute little tables! Just stop and send those along! :D
Looks like I picked a good time to subscribe! Please keep making videos and don't disappear for another year
The Wesley Treat push stick was a good touch
Merry Christmas! Hope to see more content from this channel.
Awesome stuff, you can use a screwdriver to hide the gaps in those miters on the roofs. I've done that on about every box or frame that I've made
Scoring the glass is intended to send tiny cracks through the pane. Etching a line into the surface doesn't do the same thing. This is just a guess, but using a blade that causes more damage might achieve the desired result.
I see the homemade tablesaw is gone and the sawstop is in! Nice upgrade!
I liked your aging wheels influenced push sticking @ 2:02
I'm so happy to see more content on this channel.
More video in 11:19 than most squeeze into 45 minutes. Thank you.
I liked the video as it started. Missed this content. Happy new year buddy.
Great to see a new video from you Mr Dunn
Away for a year and comes back with a banger, love it!
Yay woodworking! This is where I first found your madness.
Glad to see a video uploaded here, I hope you had a Merry Christmas!
I missed this channel. Merry Christmas y’all!
I was thinking about this channel from your last video with the 100K Electric car mileage.....oh boy, I am happy to see another video on Under Dunn. Happy holiday. Mr. Robert.
When the world needed him most, he returned
Glad to see you doing another UD video. I enjoy AW also but have missed this series.
so glad to see a new video come out on this channel
