    Not THAT question AGAIN!

    which weld Flip the coin . . . . If you are proficient and do good work they are all good. I doubt very much that one is stronger than the other. You melt two pieces of metal, insert some filler rod and let it harden. The weakest point is going to be right at the edge of the weld where the...

    new webb site

    I would like to thank everyone for the good advice provided over the last couple of years on my Acro Sport. It's not done yet so there will be more questions to come. I would also like to mention a new biplane only site at > biplaneforum.com < I thought the "tube and fabric" forum here...

    Airfoils

    The SkyBolt biplane has a different airfoil on the upper wing designed to stall before the lower wing. Can anyone with experience in this airplane tell me if this is noticable at the stall? I am considering the installation of an angle-of-attack indicator. The manufacturer says install it on...

    Drag Wires

    Why do drag-antidrag wires have left and right hand threads? Once they are locked by double nutting they cannot be adjusted and they will not rotate. Inquiring minds want to know:)

    Inverted oil systems

    Greetings, I am looking for an inverted oil system substantially cheaper than the $800 ++ Christian system. Either a manufactured system or plans for building my own. Any information out there? Thanks FlyGuy

    Inverted oil system

    Greetings all, I am building an aerobatic biplane and need an inverted dry sump oil system. I am looking at an oil accumulator built by MoCal (race car specialists) that will provide oil for up to 60 seconds when the pressure is lost and will recharge itself as soon as the oil is available...

    T-88 Glue

    The System Three Clear Coat is a two part epoxy. So far the only thing I have found that will remove it is a chisel taking some wood with it. Go to Systemthree.com, get the answers from the horse itself :)) FlyGuy

    T-88 Glue

    Jake, I will relate my experience to date. I emailed the System Three engineering dept. and asked if Clear coat and T-88 were compatible. They said there was no problem. If the Clear Coat had been applied longer than 72 hrs. it was necessary to scuff sand it before gluing to it. There would be...

    Flying wire fittings

    I have 4 each AN665-61-R and AN665-61-L flying wire fittings with clevis pins and lock nuts. All brand new never used. Wicks current price is $221 I will sell for $150. They are 5/16" fittings to be used on a SkyBolt but I have changed projects and cannot use them.

    T-88 Glue

    T-88 You can down load the manual at systemthree.com or they will send you a paper manual. I also found out the answer to my question. You can seal wood with the System Three Clear Sealer > better than varnish as it is an epoxy that penetrates into the wood and actually stregthens it < then...

    drag wire tension

    Hey Craig, thanks for the reply. The 3/16" dia. drag wires have a finite tinsel strength. If I overtighten I use up some of my safety margin. If I undertighten something is going to move at the bottom of a 4"G" loop at 180 MPH. I would just as soon that didn't happen. If I cannot stress each...

    drag wire tension

    Can anyone give me a good "rule-of-thumb" method of tightening 3/16" drag/antidrag wires in a small acro biplane without using a real tension tester? Thank you and Merry Christmas to all. FlyGuy

    bungee gear

    Thanks Wally, I will build the fuselage truss and the horizontal tubes per Pitts S-1 design. My question was the attachment at the axel. I didn't know if bolting was acceptable as it creates a pivot point and I did not see a good way to weld a new tube to this bolt area of the axel. I may bolt...

    T-88 Glue

    I have used T-88 on my last two SkyBolts and like it alot. Now I hear System Three makes a sealer (varnish) that can be applied to wood and, later, another piece can be glued to it using T-88 with the joint strength being comparable to glueing to bare wood. I have down loaded the System Three...

    SkyBolt

    I have a basic SkyBolt fuselage welded with tail feathers and most of the tubing to complete. This is my 3rd one so welding is very good. I have changed projects so I need to get this out of my shop. I will email pictures to your address. I am in SW Mich. Make me a reasonable offer and it's...
