Definitely! This could be a great place to add more support for a bolted on reinforcement bracket - or just plain old reinforcement! mod anyone tries it, I recommend a two part epoxy. I’m suspicious that this alone won’t eliminate the risk of cracking (could maybe even make it worse?) but it...

It may be the ram on the GPU - many memory chips manufactured during this time doesn’t seem to age gracefully.

These days I have practically zero interest in the color classics - but jigs like these are so cool! Kudos, it looks great

I am envisioning a perfectly form fitting bracket which is both epoxied and bolted into place — ideally, this will spread the load over the entire upper chassis rather than just the upper segment of the hinge mounth.

The broken hinge cannot be repaired with glue, it will continue to break. I suspect that the existing structure can be reinforced economically (such as metal 3D printing). I’ve been very busy recently but the direction I would explore is a custom 3D printed reinforcement bracket which is...

Thank you, these photos clearly illustrate the hinge assembly. is this a common problem? I’ve not heard of it before.

Is this portion of the chassis removable - a subframe? I haven’t had my portable open in a long time.

Have you ever used alltransistors.com? You may be able to find alternatives which are either still made (unlikely) or has NOS. Perhaps a modern transistor could be used with an adapter board.

Thanks James, my goal is to make premium quality gears available at the lowest price.

Once the “green” 3D printed resin is polymerized through UV curing it’s then reasonable robust. That being said, half an hour may be overkill.

I maintain my ISO with automatic 10 µm and 5 µm filtration, you can learn more about the system from the original author's YouTube video. I highly recommend this for anyone who prints regularly.

This is the specific distiller I bought but there are many like it.

Great reference for beginners! I purchased a purpose-built distiller to do this myself. The results are perfect … but good lord the smell of the distilling isopropyl is overwhelming. Definitely recommend some distance from people and structures - if not for the fire risk then for the...

I decided to model the spring retention bolt while I still had it on hand — this all ships back to EvanRetro tomorrow. Thank you again for loaning it to me to make a model from. I'll attach the model to the thread. The threads are M5 and the part is press-fit into the hinge bracket. It's...

Thanks to the kind loan of @evantretro, I have released a 1:1 model of the original hinge. It's available for download on both Thingiverse and PCBWay. Orders for replacements can be submitted directly to PCBWay and at the time of this post Aluminum / Steel replacement parts are just under $30...

Thanks! I would prefer if you mailed it so I could reference the parts directly. I've managed to collect excellent quality metrological equipment over the last couple of years. Regarding the tabs, you're referring to the wear inside the two red circles of the attached image?

The curvature conforms, whether there's a thin sheet of acrylic or not :) I've placed a 0.75mm sheet in mine and it will hold the curvature because it's so thin and flexible — albeit, not entirely convincing due to the refraction index of the acrylic.

Strangely, I happen to have a Lisa bezel sitting next to my desk. That should be a hint for things I (slowly) have planned. Anyway, the Lisa CRT opening is 239.5mm as a straight line from edge to edge on the width and 169.5mm on the height. Measuring the smallest points. Lisa CRT Opening: 239.5...

Nice work - mine came out so badly (with tree support and the same orientation) I tossed it straight into the bin.

Done! (added to original post)
