@Geekman Just watched it through, the video is very well done! Seeing G4 under the B&W plastic is a bit trippy.
Geekman#MARCHintosh is halfway over! Have you watched my video yet on my "Blue & White G4" restoration? I put a lot of work into this project and video and am keen to share it with the community. Please boost if you like it!

Making a PowerMac Blue & White G4
Trammell HudsonTrick to install the washing machine drive belt: use some big zipties to hold it to the pulley while alternating between two levers to carefully walk the pulley around.
@ArchiteuthisFlux Generally vibes will be enough because plating is thin compared to the hole diameter and standard drill tolerance, and solder will fill in your sins. I have had only a few PCB designs where hole tolerance really mattered because I was using Würth REDCUBE press-fit screw terminals. (Not affiliated with them, I just really like their stuff!)
@ArchiteuthisFlux Some fabs use the called out drill size as the finished size after plating, but others use it as the unfinished hole size. Even then, fab tolerance probably isn't better than ±0.005 mm!

@Extelec You can change the sheet size. I typically use B sheets because I'm in the US, but it's about the size of A3.
@RueNahcMohr That's awesome. I have a bunch of copper clad boards and ferric chloride, but I never got around to etching my own boards. I'm sure I could throw an etch resist pen in my 3D printer to do that. I like that plotter though!
