Shoptalk #23 - 01-2021 

happy new year Stefan! let's see more of the new machine!

Milling glass. A bit like watching a bomb being defused, yes?

Sometimes life can get you when you aren't expecting it. My heart goes out your way. We have not met, likely we never will, but everyone suffers and none of us want anyone else to go through what we have ourselves and that means on some level compassion makes us most human when we see another suffering. If you were here I would buy you a beer and a few moments of silence because sometimes that is all someone can do, share the burden. You are not alone, even when you don't see anyone in the room.

It's great to see you back Stefan. I've no doubt your Dad was super proud of you. Snarky comments are a sort of ultimate compliment that fathers pay to their sons.

Good to see you back, you've been missed, Stefan. I hope the break was just what you needed. A new shop tour would be good to see one day. Let's hope 2021 is a better year!

Thanks Stefan, I was a bit surprised at the glass machining🤔😁👍

Hope you're doing as well as can be, Stefan! Your content is always appreciated, no matter when it's published.

Happy new year, Stefan! I'm afraid that anything posted in a RU-vid comment is liable to sound like hollow words but, for what it's worth, I'm sorry for your loss. A cruel end to a cruel year for us all. He sounded like a good man. I hope his legacy will continue to inspire your own. Stay strong and cherish the good times. All the best wishes to you and your loved ones from some stranger on the internet. :)

Next week: TIG welding glass. ;-)

Huge pleasure to see you back in front of the camera, and completely understand your alone time in the shop. Many thousands of people out there respect you and what you do, including me. It is our privilege that you choose to share. Sincere thanks.

Great to see you back, Stefan. I had to hit your Instagram to find out about the devastation you mentioned. My sincere condolences - losing my father was very difficult, I understand the feeling. Thanks for putting this video up. Oh, now I'm following your instagram so I can see more of what you post also.

Good on you for taking time for yourself; you owe us nothing. Appreciate yah!

If you sit the piece of glass on top of another sacrificial piece (called a waster) the shelling / blowing out is restricted to the waster and not the workpiece. The waster provides support to the weak corner of the glass hole / edge. This is common practice in optical manufacturing, although we would normally use sintered or electro-plated diamond, non-fluted cutting tools. For best results, laminate the workpiece between wasters, bonded with a layers of beeswax/resin mixture.

Stefan, words cannot express how much I look forward and learn from your videos! So much thanks, so many good wishes for the new year!!!

Thanks for making time for us folks during this difficult time. You are such an amazing and inspiring person Stefan, please take care of yourself!

I am so glad to have a Stefan video to brighten the gloom! Thank you and Happy New Year. All the best to you and everyone.

Thanks Stefan for your content. Always brightens my day when i see that you have uploaded a video. Stay strong for a better year. And may he never be forgotten...

If I haven't told you before, I appreciate your wondeful efforts to teach us the excellent things that can be manufactured in the world of machining and I love the few videos of your countryside. I don't think I will ever visit that area and am happy to see as much as I can. All the best wishes to you for the rest of 2021.

Hey Stefan, Thanks for helping out Alex with his CNC project. It was very nice of you!

Hello from Florida USA. The glass machining is very interesting. Have not watched in a while. I have been very busy moving and building new shop, nearly finished.

Good to see you. I'm guaranteed to watch a shop talk whenever you feel like making one Stefan. I hope 2021 is better for everyone.

All the best from the UK. Here's hoping a better 2021 is coming. Thanks for sharing your shop and I look forward to more!

Love your content! I agree 2020 was a mixed bag of emotions, I personally missed the regular videos but I caught hp with some of your older content. May you have a prosperous 2021.

Tolles video! I can't believe that you can mill and drill glass with carbide. Amazing

"We won't centre punch it"... That was a German joke, wasn't it?

Nice new machine, love it. Never seen glass machined, interesting. Love the Luer lock idea. My sister in law is a vet. (animal doctor) she supplies me with all sizes of old stuff, I use it all the time. Thanks for sharing and your support.

Happy New Year to you Stefan. Love your Shoptalks. Looking forward to more. Stay safe everyone.

I have worked with glass for a good while. Glass can take very high compressive forces but will not tolerate tensile stress. Usually we drill glass with diamond coated drills but i quess its the same with tungsten. When making a hole in glass you push through only half way. Then you need to drill from the other side rest of the way. This way all cutting forces are compressive and glass wont brake. When dealing with glass the most important thing to keep in mind is that glass can take huge compressive stresses but will brake with little tensile stress. This is the way glass cutters work. You make imperfections on the surface and make tensile stress on that side and glass breaks along the line of imperfection.

Happy New Year to you and the rest of the viewers. Thank you for the glass work. Not sure where I would use it but another page in the notebook, tool in the toolbox, etc.

Happy New Year Stefan!! The new shop is as bright as the snow at the end..Your video's are among my favourite on YT. You and Abom79 were the reason I purchased a Lathe and Mill..I purchased a VDF Heidenreich & Harbeck 18 RO lathe last year, I have been using it for making tooling and odd parts in between slowly refurbishing it. Love your videos. Andrew Australia

Another shoptalk! Always a pleasure to see one of your videos!

Great to see you back at video making. The glass milling was awesome. Great idea on the luer lock tips for the blow gun. I understand the need for the alone time to work and get your mind off of certain things. Been a rough year for many people for many reasons. Thank you for the video.

Thanks for all last year’s awesome content, Stefan and am looking forward to the rest of this year. From my family to yours all the best. Play Safe From Elliot Lake Ontario Canada.

Happy new year Stefan! Great content as usual, I always learn something new in your videos.

Glad to see you back and with new machines and techniques. Plus a ride through the countryside! What’s not to like? Stay safe and we’ll, Stefan, and Happy New Year.

Super cool, I had no idea you could machine glass! This is one of reasons I love this channel, I learn something every time. Now I can't say I'm not a little disappointed that you didn't film the building of the CNC but, I can understand and respect why you didn't. 👍👍

Dang bruddah! Haven't seen an upload from you in a while. Always learn something when I watch.

Happy new year Stefan. I’m new to your channel but have enjoyed every video I have seen so far. Thank you very much for all of your insight, and videos.

Nice to see you back Stefan. Condolences on your loss. Can’t wait to see more with the new machine.

Wish you a better year too! I'm very glad you're back , it was a pleasure to watch your next shop talk on Saturday evening. My router is also waiting for an upgrade, new JGL 80 spindle for ISO20 holders is waiting in the box, hope I'll find some time to replace it this year...

Happy new year good to see you back.very interesting idea of milling glass ! Keep well look forward to more as you get time. THANK YOU

All the best for the New Year toyou and your loved ones. may 2021 be a better year for one and all. Love all your content Stefan. Keep up the great work

First a video from Robin Renzetti, then one from you. An excellent start to 2021.

Happy New year. Fantastic information on glass machining thank you so much! I get asked to do this quite often at the day job and never got tight sizes with diamond abrasive jewelry type tooling. 👍👍👍

Thank you Stefan. Your videos are always fascinating and I always learn something. I never would have thought of machining glass with ordinary carbide endmills and drills. Happy New Year.

Happy New Year Stefan. You always have interesting videos for all your watchers. Keep up the great work during the New Year.

Happy New Year to you and family. The part about machining glass was very cool! Thanks for sharing and good luck with the new machine

Happy 2021 and all the best in terms of your physical health and enjoying your machines, both as a serious professional and a spirited schoolboy at the same time! The glass cutting only exemplifies your admirable ethos to machining! Thanks for your videos that I always look forward to watching. Stay safe.

Great to see a new video Stefan. Nice machine - looking forward to seeing you accurize it - we all know you'll want to make improvements!! Thanks for sharing your time and expertize.

Very glad to see you back. Hope 2021 is better.

Glass. With a milling cutter. I'll be darned! Happy New Year from our wee island in Virginia USA, hope 2021 is better or at least more entertainingly weird for all of us. Nice looking router too!

Thanks for the nice little chat, very interesting outcome on the glass machining. I have had luck with some small diamond coated drills, but did not thoroughly check the exit side like you did. Anyways, Happy new year Stefan, peace and good health to you and your family, cheers!

Happy New year Stefan. Nice router, looking forward to seeing it in operation. So glass can be milled, who knew (other than NASA)! Great to see you back in the shop. Cheers, Jon

I always look forward to your videos! All the best in the new year to you and yours. It takes time, but it does improve. I've been there.

Happy New Year Sir. Your content is always appreciated. I love your curiosity and desire to learn and then share with us. Thank you!

Great video as usual Stefan, thank you for posting these informative and at times eye opening pieces. Happy 2021 !

Best wishes for a Happy New Year. As always I appreciate you sharing your knowledge. I’ll be looking for Luer Lock fittings Monday. Cheers, Will

May I wish you a healthy and prosperous 2021. Excellent addition to the shop Stefan, lovely looking Machine. Thanks for sharing and stay safe all. Best regards from the UK. John.

Hope you have a good year Stefan! Don't worry about your upload schedule. We're very lucky with the videos that you do upload and I've benifitted many times from them as a instrument maker myself. Many thanks

Vacations are needed as well. Glad to here you took some time for you, we all do, love the vids

A good start to the new year is a new posting from Stefan. Thanks.

Happy New Year Stefan. Thank you for sharing your time and many talents! All the Best... Chuck

Thanks Stefan! As usual you make my day! Love you channel and content. Thanks and Happy New Year!

Thanks for the video. I never thought you could drill / mill glass like this. I’ve done grinding with diamond coated pins with good results. I hope 2021 is better for all of us.

Love the new machine and all of the information on glass work (amazing) Great video and thank you Stay safe!!!!!

Happy new year Stefan! Glad to see you are starting to feel good enough to do some videos. New machine looks great and the glass was awesome. ATB, Robin

Happy new year. Thanks for all you have time to share. Always incredibly interesting and inspiring. 👍👍😎👍👍

Happy New Year Stefan 😊 Thank you very much for all the wonderful content-Always interesting and educational, thank you 👍😊🎁

All interesting topics. Totally understand about wanting to get some good, solid work in without needing to worry about the camera, lighting, etc. Happy New Year to you, and let's hope for a better 2021!

Thanks for sharing Stefan. Great stuff that you let us watch. I wish you a healthy and the best wishes for year 2021. Stay Safe.

Happy New Year Stefan! Wish you all the best in 2021.

Happy new year, Stefan. I am glad to see you posting again on here. Wishing you well sir.

Happy new year. Congrats on the new machine and thanks for sharing a mind blowing (but not glass blowing) video on milling glass. It's always good to know - even if I don't plan on doing that right now... or ever :)

And thank you too Stefan for such a good content. All the information generosity is much appreciated as much as enjoyed. Keep up the good work. 👍

Great projects !!! Cutting glass with a carbide end mill and tap magic. To add steel to glass, a flexible isolators can used to mitigate thermal expansion differential. Thanks for sharing.

with many thanks and good wishes for the new year, Danke Stefan.

A little late Stefan, but happy new year! Absolutely can relate to what you're saying, I have at times no energy spending time on my hobbies! Watching what you share on this channel is a delight and helps me coping better with the circumstances. Thanks a bunch for the info and making me feel better! Kind regards, Donald

Thank you. I was very happy to see a new video from you this morning. I saw the new machine on the Instagram and was looking forward to seeing it on RU-vid. By the way, I was taught [many, many years ago] that the preferred coolant for cutting glass using typical spear type widia drills was [lamp] kerosene. And to prevent blowout I usually put the glass on a small piece of rubber located directly under the planned hole (with corners supported by something soft, like a soft foam).

Thank you for working on these videos, at all, in these sick times.

Nice to see you back, 'we' missed you Glass drilling/milling experiment was interesting. About 15+ years ago I bought some 'glass drills' which were more like spear point spade bits.. Came with instructions . Never thought about milling glass though, may have to try it. Luer lock was something I didn't know was actually available unless you were 'medical, dental, hospital, etc' and needed them by the hundreds. That adapter will be just what I've been looking for to blow out small air passages in carburettors I modify for 'vintage' (1960's-70's) motorcycles

Totally understand the silence, and if you ever need more, take it. We'll be here when you get back. Also, learned something (multiple things actually) from this so big thumbs up.

Happy New Year Stefan! Thank you very much for all the wonderful content-Always excellent ✅

Very much enjoyed the video, have missed your uploads since the end of 2020. Glad to see you are doing well. Take care and stay safe. I will be watching for new material from you. Bob

Hallo Stefan - immer wieder sehr interessant Deinen Shop-Stories zu folgen ! Jahre können "Devastating" sein - manchmal gleich doppelt und man wünscht sich auch nach Jahren, man könnte nochmal reden. Ich wünsche Dir weiterhin interessante Ideen und Aufträge für Deinen Shop und freue mich auf weitere Folgen - auch mit Deinem feinen Humor.

Stefan Happy New Year, Lets hope that this year will be more rewarding. I really liked the Luer lock adapter.

Good to see you again Stefan, and Happy New year. I understand you are going through some hardship, and I really hope things work out in the end. Life has a tendency to through surprises when least expected. 2020 has been a year to forget in many places of the world, maybe something good will come out of it eventually. Good luck, and thanks for taking the time to post a video again with good content. Best wishes.

Happy and prosperous New Year 2021. Thank you for sharing your knowledge.

2021 going to be a good year. Steph's back with a vid. Happy New year. 😁👌

Awesome video as always Stefan, hope you and yours had a great christmas and new years mate, glad to see you again haha

Looking forward to seeing the new machine in action. Love the tee shirt.

The chip breaking abilities of those little carbide tools is most impressive. ;-)

Happy New Year, Stefan. Interesting and instructional as always.

Happy New Years Stefan.. Looking forward to your next videos.. Take care !

I'll be back -- that sounds ominous, in a German accent... I always greatly enjoy your videos, especially your gründlichkeit and depth of knowledge.

Great to see another video. The shop, the machine and even the T-shirt is a switch.

It's good to see that you are doing well.Thanks for the tip on the Luer tips, I new that they exist but didn't know who made them.

Very interesting video as always. Happy new machining year 2021 Stefan.

I'm surprised you don't center punch the glass, as obviously you like living life on the edge- machining glass, driving on the wrong side of the road!!!! nice to see you back. happy new year

lot od power to you, blessed 2021, and thx, was waiting for new stuff from you... br...

Long time sub, I don’t say much, but I really enjoy this channel/content. Thank you. And machining glass who would’ve thought, awesome 👏!!!!
