The Magic of Flameworking: Crafting Electrical KF25 Vacuum Feedthroughs

The plan is to make two electrical vacuum feedthroughs out of glass. These are to be used later in my Van Arkel de Boer process. So that I can attach these feedthroughs to my apparatus, they should have a KF25 flange or at least be able to be connected to one. It is fascinating to watch a professional at work. It never ceases to amaze me how easy it looks to shape glass the way you want it when done by someone who has had a lot of practice. I hope you enjoy the video! If you want, you can join my patreon to help me working on my projects. I would really appreciate it!   / advancedtinkering   Music: Song: danyvin - Aesthetic Things Music provided by Tunetank.
