I use mineral spirits, and have not had issues. Some folks recommend this stuff, But I have not tried it: https://www.tractorsupply.com/tsc/product/crown-psc-1000-parts-cleaner-5-gal

This is wild. Mine would be raising a racket at 3am playing in the tubes. Is it relatively quiet?

This is really cool.

Let’s hear all about your progress. Don’t disappoint your judgmental internet buddies!

I don’t know why this is such an appealing project, but it is. Adding an LED and a switch so it can be used as an emergency flashlight would be cool too.

Yep. I also think the ham-fisted way they are rolling this out is a projection of how they think the ‘libruls’ are brainwashing the kids.

Rather than educated people coming to educated conclusions on their own across vast segments of society, it is almost as if they think there is this secret committee of hooded Illuminati that generates Disney princess woke coloring books to turn little Billy-Bob away from Jesus, and the rest of the country just marches unthinkingly in lockstep with those orders. So of course, that is the playbook they want to follow.

I somehow feel this will backfire spectacularly. Younger kids can be dumb like the rest of us, but there is one thing they are exceptionally smart about: spotting and mocking lame-ass adults.

There is already little tolerance among (a lot of) younger folk for climate denialism and general right wing jackassery. Adding a cut-rate Donald Duck screeching about The Protocols of the Elders of Zion or how windmills are dangerous is just gonna’ cement the lameness for them. Now, if we could just do something about the grown-up idiots on Facebook, we’d be cooking.

I believe congratulations are in order. Getting a good surface finish on a lathe can be really hard, but you did it!

Making any progress, you slackers? Tell us about it!

I'm grabbing popcorn for this one ...

(Not to be one of those people who comments but doesn't offer help, if it were me I'd replace the entire base. One possible suggestion - find a different base second hand and adapt it to fit the chair. There is no karmic rule that says the base has to be the same brand as the chair, or even match it. It all depends on how the existing chair attaches. You might even take the modifications to an extreme).

High tech scroll. Love it.

The internet is full of places where low grade antagonistic sarcasm is considered a desirable way to communicate. Those places tend to be toxic shitholes, but whatever. Point is, if you feel like that communication style fits you better, go forth and prosper.

Let's hear it. No project too big or too small.

Build Your Own CNC! (www.youtube.com)
submitted 1 year ago* (last edited 1 year ago) by circularfish@beehaw.org to c/diy@beehaw.org

I know there are a few out there who are interested in subtractive CNC (there are literally dozens of us!) but who may be a little bit intimidated by it. We've all seen our calendar app or Netflix account or some other piece of software go haywire suddenly and without warning -- imagine if it was connected to a razor sharp cutter spinning at 20,000 RPM. Yikes.

I won't lie, building a working CNC machine isn't exactly a cakewalk, either. But reassuringly, neither is it rocket science. 3D printers, which we all know and love, are just dinky little CNC machines with an extruder on the business end instead of a twirly metal thing (the endmill in the case of a CNC mill).

Component-wise, stepper motors, ball screws, and control interfaces have evolved to the point you can get quality parts that fit together in predictable ways for commodity prices online. And once you have your machine up and running, you'll be able to make just about anything - it is the ultimate DIY rush to be able to visualize, design, and create something new, robust, and beautiful out of a solid chunk of metal. Building that project and need a funky bracket that has to stand up to heat and torque? No problem. Decorative hat hook for Aunt Mabel? Get outta here.

"But Circularfish," I hear you say, "that sounds great but I don't even know what a 'stepper motor' is". Never fear, popular machine tuber This Old Tony has created a series of videos demystifying CNC. He is fairly entertaining and, even if you have no intention of building a CNC mill, it will help you understand what is going on with your 3D printer when it decides to crash itself at 4am. Enjoy!

Nice. Is that PETG or PLA?

Thought I'd share a recent build for an ongoing CNC milling machine project. The Mill needed a solid base as well as storage for the liquid coolant pump and oiler, and some drawers for tooling.

I've found that you can get nice looking results welding up a frame from 2" square tube and then use bog standard melamine panels for the sides.

3/4" angle can be welded in to hold the panels and hide the melamine edges.

Add some simple box drawers and Ebay slides, and voila...

The drawer pulls are leftover continuous aluminum extrusion. Again, they hide the edges of the melamine.

Anyway, not rocket science, but thought I'd pass the build idea along!
