    A couple more pictures for you John. "Pass Seat" photo: the rear of the seat is on the left. Note how there is a wood support piece across the seat back from the left side of the plane to the right. At the ends of this piece are two vertical pieces that stand on top of the white ash cross member. Also note how the seat bottom side rails also rest on these two vertical pieces. The front area of the seat structure is also made in this same type of fashion. "Pass Seat2" photo: the rear of the seat is on the right. This is an over view of the finished product with added center support and gussets, but you can see from another angle how the seat structure was assembled. My seat top plywood is 1/4" thick and screws onto the structure. This will also add some strength to the entire assembly. For future reference; I added a plywood stiffener under the rudder pivot support bracket shown in "Pass Seat2". -------- Mike Perez Read this topic online here: http://forums.matronics.com/viewtopic.php?p=466232#466232 Attachments: http://forums.matronics.com//files/pass_seat_173.jpg http://forums.matronics.com//files/pass_seat2_798.jpg

    Mike as always great help and beautiful work! Are those heal brakes? Could you share any other detail? Thanks!

    Subject: Heel "Brakes"
    From: "Speedbrake" <speedbrake@sbcglobal.net>
    Jack, this is in response to your question from the "Front Seat Attach..." post. (Thank you for the kind words; by the way.) Yes, the items in question are heel "brakes". I say "brakes" because these are not intended to be brakes as in to hold the plane during run up or to stop short on a runway. This setup is to merely apply friction to the wheels in hopes of preventing a downhill run into another plane or into a fueling area. Pictures 1 and 2 demonstrate the break down of the pedals. Note the right side wood block is contoured to give clearance to the inside radius of the 1/2" S.S. tube. The blocks are NOT drilled through so that the 1/4" S.S. pivot tube is free to rotate. The 1/2" tube is also free to rotate on the 1/4" pivot. Pictures 3 and 4 show detail of the cable assembly at the pedals. I flared the S.S. tube and added a washer to prevent the black cable sheath from moving under the clamp when applying the brakes. Not shown is the other end of this flared tube. ( But I do have a picture.) It is rolled inward to prevent the black sheath from pushing out. The wood "U" shaped gusset it epoxied around the clamp to prevent it from rotating around its mounting bolt. Pictures 5 and 6 show the completed assembly with epoxied "T" nuts and the under belly fabric stringers. -------- Mike Perez Read this topic online here: http://forums.matronics.com/viewtopic.php?p=466237#466237 Attachments: http://forums.matronics.com//files/brake_452.jpg http://forums.matronics.com//files/brake2_940.jpg http://forums.matronics.com//files/brake3_626.jpg http://forums.matronics.com//files/brake4_186.jpg http://forums.matronics.com//files/brake5_117.jpg http://forums.matronics.com//files/brake6_139.jpg

    Mike, Looks like you are using the front of the seat for a rudder stop? Would you happen to have the distance from your alum. stop to the center of rudder bar? Assuming this gives the correct rudder throw? Thanks Rob Read this topic online here: http://forums.matronics.com/viewtopic.php?p=466246#466246

    My mock fuselage made out of Home Depot fir and gorilla glue. Was a great help. Ended up widening my cockpit two inches, leaning the rear seat back a bit , raised the instrument boards, and a couple other small changes. Also since I had never built a wood aircraft before it helped me figure out the best way to cut the longerons and gussets and fit things together generally before I started cutting that expensive spruce.
