    Scarfing 1mm birch plywood

    Had to cut over 50' of scarfs for the wing skins alone (.0625"; 1.5mm), so I made a power tool set at 12:1 to rough it out, then refined it by hand with a setup like TiPi. Steel brush the joints to remove dust before gluing. Let the glue (T-88 in my case) soak in for 15 min and apply more if...

    I-beam spar question

    Thank you. Yes, entire design. #1 goal - something different! 5400 hrs over a 15 yr period, not to mention countless hrs just staring at it wondering, 'How am I going to do this?'. Got help for the stress analysis and general design norms before construction. Borrowed ideas including Fisher...

    I-beam spar question

    TJTX, Just finished my own-design all wood airplane. Signed off but hasn't flown yet, so take any advice with a grain of salt! Happy to help with techniques, things learned. GSport

    Encouragement and product plugs for those wanting to paint at home

    My own design. Goal: something different. 2 place, UL Power 350iS, Airmaster electric prop, all-flying tail, full-span flaperons capable of reflex, GRS chute. Firewall 'just happens' to match an RV-6 (did not want to do THAT much glass work), and windshield is a cut-down RV-14 canopy. Truly...

    Encouragement and product plugs for those wanting to paint at home

    Successfully doing fabric and painting in the basement which is open to the rest of the house (high-risk environment!). Using Stewart Systems for glue, fill and primer - hardly any odor for any of those (no topcoat yet). Using Eastwood QST 30/60 scroll compressor - very quiet, the claims of...

    Is wearing a personal chute with a bail-out system acceptably safe compared to an airframe chute?

    I haven't seen anyone mention the ability of an inexperienced passenger trying to exit a disabled aircraft. This is one of the main reasons I went with a whole-plane chute (Galaxy GRS). After watching many videos of ballistic chutes actually being deployed, there were some where it was obvious...

    GPS and ELT Antennas

    Thank you! (second part of the question) can the comm antenna also serve as the ELT antenna?

    GPS and ELT Antennas

    Can the same WAAS GPS receiver serve as the GPS input to an ELT which has a 'GPS Interface', using a coax signal splitter? (I'm assuming it uses coax for that connection) Since an ELT is "never" used, can it's signal be routed thru the comm antenna, again using a splitter - rather than carrying...

    Meathods for scarf joints in ply

    Here's what I made, inspired from an old EAA publication. (all MDF) Mount the drill at the desired angle (e.g. 12:1) with a threaded rod large enough to support a 2" diameter drum. A small steel tube "bearing" supports the other end. The outer fence is adjustable to allow for a deeper cut...

    Personal Parachute vs whole aircraft ballistic parachute

    Foundationer, I agree, for single-seat an individual chute would probably be better and far simpler. For others still facing this question, I'm building my own-design 2-place and chose to go with the whole-plane chute. Rationale: 1) Many of the 'save' videos is what sold me - they never...

    Sealing Plywood Wing Nose Skin

    Pictures may help. This was a 9' x 5' sheet of 1/16 birch, pre-soaked with towels top and bottom overnight, then squeezed into a 10' section of 3" tube (tried wrapping it on the outside of the tube, but couldn't get it tight enough) plus with the ends of the tube sealed I was able to soak it...

    Ztron Lights

    Thank you Hot Wings! That's what I remember seeing. I just now typed in that exact address (except the 'manual.pdf') and got a blank page again. Hmm. Thanks for finding that!
