    TIG, stress relieving

    LS... Videos not working for me at moment. You have really thrown me off my M&P game. TIG = tungsten inert gas... hence I'd expected an electric arc from the tungsten anode melting the braze alloy... which would destroy everything alloy and base metal. SO I poured-thru the AWS brazing handbook...

    Klixon circuit breakers as switches

    An electrical fire is a terrifying and deadly prospect in-flight. Following best/professional-practices usually results in a robust/safe/worry-free/low-maintenance system.

    Someone finally built a manned "drone" and its worse than anyone expected

    CR, all... this is also termed an 'optionally manned aircraft'... humans may/may not be aboard. Safety factors in-mind for our universally pink-on-the-inside-bodies... since this vehicle appears to have no aerodynamic lift, stabilizers or controls or forward propulsion…...

    Wooden floor size suggestion please?

    I vote for aluminum or SStl sheet flooring primed and sealed and appropriately 'drained'... or plywood with VERY careful attention to installation details. NOTES. Corrosion protection due to high probability of being 'constantly wet' is important. Also be cautious about draining off, and/or...

    Unadvertized secrert abilities

    Use special drill bits designed for acrylic/polycarbonate. These have a 60-degree point angle with special tip-features and spiral flutes for drawing-out chips safely. With some practice conventional 135-degree point HSS drill bits can be sharpened and re-ground to make various diameters...

    Aluminium spot welding for the Homebuilder?

    Aluminum resistance [spot, seam, etc] is a lot more difficult than it appears. Primarily because aluminum is so conductive it bleeds-off electrical energy/heat needed to fuse the nugget at/around the spot between layers of materials. More than just electrical current, though, there has to be...

    Crashes in the News - Thread

    Lesson learned by professional missilemen decades ago. Everything that could interfere with the vehicle, or rebound toward the vehicle, has to be forcibly/permanently pulled-faraway from the vehicle seconds before lift-off commit. The failure to secure the ladder could likely be the evidence of...

    Crashes in the News - Thread

    Wondering about the recovery chute design... survival was ultimately dependent on the recovery chute operating 'perfectly'. Hmmm. WHY wasn't a BRS or similar ballistic deployed chute 'professionally designed/installed/configured for the 'flight'? I suspect that a BRS would never participate in...

    No one can explain WHY planes fly...

    As a long-time aero engineer, the precept of this thread is a bit like "how many fairies/angels can dance on the head push-pin... now prove-it without reference to web videos, articles and commentary". Some of these discussion points are surreal without a solid engineering science background...
