    New search engines

    Ran across an AI powered search engine that looks interesting and possibly useful. It is kind of a cross between a simple search engine and Wikipedia . Perplexity.com

    More than a shop stool

    Today I needed a second hand to help with a couple of small jobs and didn't have anyone around. Turned to one of my favorite shop tools for holding the other end of a long part: These are the old 'pop' type lab stools, just like the ones in my high school Chem lab. Got them at a local...

    Homebuilt Ballistic Parachute

    Moderator Note: Forked this discussion off from the VP-21 thread, to preserve that topic. I'd seriously be interested in a thread for home brew BRS. I'd expect Riggerrob to be a valuable source of information/advice/experience. The earlier systems seem to have been validated, at least before...

    Winches, Motorgliders, and Soaring, Oh My!

    Moderator Note: This discussion was forked out of the event thread for the 2023 Experimental Soaring Association Western Workshop Symposium, so that I can start posting links to the lecture videos there...

    Garage Level Design 101

    Ran across this guy on YouTube recently. I'm kind of impressed with his simple way of explaining things that many of us here learned a few decades ago = high school level* shop and everyday 'how things work' physics. No esoteric engineering concepts or math, just some good common sense (IMHO)...

    Books: Adhesion Science

    Ran across 2 books today dealing with adhesives and adhesion science of which I was completely unaware. They are both $600 books, but if you have an *___*.edu address, or know where to look, they can be downloaded. 2032 pages total, so I obviously haven't read all that much, but from what I've...

    Frise aileron as an elevator?

    Yes, kind of an out of the box - a well tattered one - thought. Reason? To reduce stick forces on a flying wing and keep the pivot point out of the body of the elevator for assemble and maintenance reasons. A simple offset hinge would do the same thing, and eliminate the potential 'snatch' of...

    Aviation Mega Joke of the Week

    We still don't have a Vaporware category so this is where it 'lands'. https://www.dailystar.co.uk/tech/news/designer-shares-scary-concept-video-27332702

    Fractal Vise

    Ran across a tool I'd never heard about while researching a 3D printer upgrade......................Squirrel down a rabbit hole. Fractal Vise Probably not a lot of need for one - except when there IS a need to grab onto something irregular.

    "FREE" AV-36 and AV-361 plans

    Due to multiple parameters in my life, some of which none of us have control over, it has become quite obvious to me that I'll probably never be able to build an AV of my own. This means that there is no way I can ethically offer any plans to an aircraft that has not been built and properly...

    Compression testing pultrusion

    I have some fiberglass pultruded rod I'd like to test for compressive strength. It's going to be between 1/4" (6mm) and 3/8" (9mm) and I'm expecting total loads of between 4000 and 8000 pounds. The manufacturer supplies data for tensile strength and modulus but nothing for compressive. I'm not...

    The rise of FrankenEngine - An engine for the VP-21

    A bit of background: A little more than a decade ago I decided I needed an engine for my Quickie project because the Onan was no longer available. I built a ½ VW with the intention of using that. Ultimately I decided that it wasn’t a good choice. This lead to thinking about building an engine...

    Aeronca Chief for sale

    Not mine - belongs to my brother that is now short of hangar space. Located at KCPR Casper Wy. Believe it is a '46. Just can't remember - it's been around 40 years since I helped my brother restore it the first time. When I asked him for details this was his response: "Was asking 17k. Less...

    810 Briggs Rabbit Hole - New Head Branch

    Forked off from another industrial engine thread. Decided to take a few hours to see how much potential a new head casting for the 810 B+S engine might open up. The sketches below have all of the essential original B+S parts in their original location (+/_ 1mm or so). The block in the assembly...

    Upgraded aircraft design "software"

    Just upgraded my old school calculating device with one capable of greater precision/resolution. 🤔 Just couldn't pass it up for $9 and a 3 minute drive.

    Another Solidworks question - Prints/Drawings

    Tired a Google and looked on YouTube but can't seem to get the right search parameters. I've got a set of ribs for a tapered wing that I'd like to print out on a single sheet. But I haven't found an easy way to overlay the parts on the sheet in an orderly manner - other than by eye. In my 2D...

    Whiffle tree question

    I'd like to set up a Whiffle tree but I'm having a hard time visualizing just how to do it. My problem is that the structure I'd like to test isn't flat and I'd like all of the final loads to be normal to the surface - as they will be in the real world. The picture below is kind of the opposite...
