why i had to kill my beloved electron beam project after running the numbers and working through the failure modes, I just cant justify this machine anymore its a high voltage death trap this design needs 30–60 kV to drive a usable beam that’s insta dead territory insulation, arcing, corona discharge, tracking across dust or humidity etc...all nontrivial 60 keV electrons slamming into metal = bremsstrahlung x-rays it will emit radiation, shielding isn’t optional you need thick steel or certified lead shielding, properly grounded and tested. not something i can DIY with confidence The number one reason this project was killed was actually because of powder handling is a nightmare titanium, aluminum, inconel powders are all highly combustible, and all health hazards if inhaled. they’re respirable, toxic, and capable of igniting from static discharge or friction a few years ago a technician died from static discharge when printing in aluminum you NEED inert handling environments, antistatic everything, class D fire suppression and the list goes on in other words: not some sh*t to keep in a garage everything in EBM is hypersensitive to contamination vacuum instability, inclusion defects, powder degradation, etc ambient humidity can destabilize the process i don’t have a clean room, and i’m not going to build one to babysit reactive metal dust and finally regulatory hell to legally operate or commercialize something like this, you’d need UL or CE electrical safety compliance. that means passing shock, arc fault, insulation, fire containment, and emissions tests that alone is a full-time job and that’s before you get to the radiation safety filings. cool tech, industrially viable, But its not ready for a maker market . All that being said , I learned alot from designing an electron gun , , such a simple concept, no moving parts , i love it. cant wait for another excuse to make one LOL

So we just got this thing on casters so we can move it around the shop easily Our preliminary damage report is that it doesn’t actually seem that damaged The previous owner said that he had it for a citation 500 and they decided to get rid of the airplane so the last time this engine ran was in 2013 however, one of the compressor blades came off and went partially through the engine However, it didn’t go through to the turbine so it’s somewhere in here. We just have to find where it is. But in theory, it shouldn’t take too much to get this thing running for right now we’re just gonna be focusing on the teardown and we won’t know it’s ultimate state until it’s fully disassembled But so far things are looking good

Week 1 of the JT15D teardown is done! We pulled the accessory gearbox, got into the external engine lines, and started getting a real feel for what 10+ years in a warehouse does to an engine. Every fitting was a fight, every seal was fused, and I learned pretty quickly that this teardown is going to demand a lot more patience than I expected. One thing I did not anticipate is how long quality videos actually take to produce. Between the teardown sessions, the scanning, the documentation, and everything else happening on this project, there is just not enough time right now to film and edit the videos I actually want to make. So for now I am capturing as much footage as I can, and once the teardown is complete I plan to go back through everything and put together videos with a bit more production quality behind them. Massive thank you to Jim Belosic (SendCutSend) Maxim Lobovsky (more on that soon) and every single person who contributed to the crowdfund. NONE of this would have been possible without all of you all who decided to support this project, so thank you! An on the ITAR questions, I ran it by an ip attorney and they cant find any issues with doing this, But we are still going through the proper CJ paperwork to have hard evidence that this engine has ZERO compliance issues. This is only the beginning.

a mutual here on x asked me how professionals design wings for aircraft and drones in cad, so I put together a quick, high-level overview of how this process is generally done, and showed how the 3d model is constructed if anyone wants a high-level or technical breakdown of anything aircraft or jet engine-related, just shoot me a dm. if I’m knowledgeable on it, I’d be happy to make a video explaining it at the level of complexity you’re comfortable with. same goes for any powder bed metal 3d printing processes, specifically dmls and electron beam sintering

this is a CATIA V5 extension called PYCATIA and it allows you to automate as well as create components in a purely data driven way, this is the direction that I would like to see more of from the people who want to make a professional tools for engineers in this extension you are still driving the inputs , however this is far less error prone when you have complex surface or tons of features that you have to change the fundamental problem with using pure LLM output to design mechanical components is it lacks the grounding in constraint-based parametric logic that real world CAD systems depend on. LLMs hallucinate geometry, they don’t model it. PYCATIA bridges that gap by letting you bind natural-language or data-driven inputs directly to CATIA’s kernel. this is the kind of tool that makes AI a actual engineers assistant not just spitting out STEP files that look plausible but building them from relationships references and real constraints. more tools should be built this way, coupled with existing industrial software, and building AI functionality on top of this
