ChatGPT contends that for use on polycarbonate, the original 24-hour cure JB Weld is better than the clay putty stick. 🤷‍♂️ Separately from that, I was able to clean and lube the cylindrical hinges, thanks to my seeing how @techknight used pliers to squeeze the end and push to get the inner...

Okay, Guys. @Oelmuvun got my brain thinking about hot-welds. What if we just forget the crazy expensive (for me) and toxic Weld-On 16 and instead ponder alternative welds? Let's start by considering the techniques shown in this short video (worth your time to watch): With that video in...

@Oelmuvun Ideas like that are the very reason I started this thread. Different people have different great ideas, and collectively, we can perhaps come to the best overall fix. I honestly had not thought of using anything like that before. I must profess my complete and utter ignorance! But...

The question at this stage focuses on what cement I should buy. Because even if I drill or add sewing needles, etc., the plastics still need to be somehow glued or welded together. The metal parts we've spoken about would serve as "reinforcements." If you've read the previous posts, you know...

Using "bolts/machine-screws" is not practical based on my observations of the machine, and you can kind of see that in the photo I marked up with measurements in my earlier reply to you. Why? Because the 5 Ribs are just too thin, as you could see from my measurements. And if you read earlier...

@RolandJuno Thank you so much for answering my Question #1 !!! That's the GOLD MEDAL ANSWER! 🏅 More specifically, from the part of the video you kindly linked for us, large pliers are required to squeeze that protruding piece (see below), then push inward to pop that piece out the other side...

Well, “removing” the cylindrical hinges from the left and right sides is truly easy, just as you kindly showed us. But how to OPEN/DISASSEMBLE each of those two hinges after they are removed, in order to lubricate or check lubrication, is still the mystery. (Question #1 in my opening post.) No...

You mean recreate the entire main structural piece? It's a pretty complex frame, as you can see at right in tech knight's video at 11:34. Bruce Rayne shows it even more clearly in his video here. That main plastic structural piece is basically holding nearly everything except the keyboard and...

In my review of the BABY FACE, oh yes. I had a lot of noise on the 12V rail shortly after power on, such that it even appeared on the CRT. I show that in my video with scope measurements following, starting at 23:29 below...

My experience with sub 1.0mm drill bits isn't good. They almost break when I look at them! :) Seriously, they aren't strong, and that's why I earlier said that even "titanium" at those diameters might not even be adequate. (Mitutoyo calipers used for all measurements.) Underneath the 5...

OK, well... While I ponder the toxic and cancer-causing risks of Weld-On 16, I'd like to go back to my Question #1 of my opening post, which no one has touched on yet. And maybe nobody replied to Q1 because no Portable owner has ever considered lubing the two removable hinge parts? @techknight...

@phunguss I greatly appreciate your input! Luckily, both 4 & 16 are sold on Amazon Japan, although 4 is more expensive than 16 because it comes in a larger quantity can. I asked ChatGPT to compare ingredients and tell me which provides the best weld for Polycarbonate — an important...

@Paolo B I greatly appreciate your time to offer some thoughts. Those ribs are tiny. Drilling top-down into them for the sake of inserting a metal rib (the source of which is currently unknown) is scary to me, personally because the size of the drill but would need to be super tiny. The...

Help, “Pretty please”? 😢

Voltages are lower with the Meanwell module type replacement PSUs. When I reviewed the Baby Face PSU, I compared it to the Stock SONY and to the SEASONIC modern replacement PSU, putting voltage measurements in my spreadsheet below...

Two questions for my fellow Portable owners, including @techknight … Question 1: What is the step-by-step procedure to clean and lube stiff hinges? Question 2: My Portable’s screen was always hard to open, requiring me to press very hard on the right side of the handle to open it. Tonight I...

Correct in that my joystick kit does NOT include the "rubber sleeve" that slides onto the shaft. I found a YouTube video with a greed colored rubber sleeve on the shaft as shown below... Again, mine didn't include that at all. Not sure if that's good or bad, but the product page shown below...

Welcome to TinkerDifferent! With the exception of the floppy drive (which doesn't matter in this case), you clearly have a fully recapped machine. Not only that, but you also did this... By HOT you mean the BU406, correct? If so, great call. Reflowing all the connector joints was also a...

"Rubber"?
