Date Description Time
03.04.01 Installed safety pins on brakes, cable attachments, pushrods and throttle rod. 1.00
03.03.28 Moved parking brake valve and cable holder 3/4 inches to clear the pedals.  Replaced the straight fittings on the master cylinders with 90 degree elbow fittings (to reduce the stress on the hoses).  I've done this with Danny Dubois who came here to visit and ended up helping. 3.00
03.03.26 Re-installed lower control yoke assembly 0.50
03.03.25 I went to my Judo session and thought about verifying if the shackles interfere with the parts supporting them.  Yes, one of them is a problem: the lower control yoke cable attachment point.  I ground the control yoke plate and… it does not solve the problem entirely.  Looking at how this works, it seems that past a certain point, the cable flexes more upward after B6 and tension is increased against the fairlead of Bulkhead no 6.  The situation may be accentuated by the fact that my stabilizer is mounted really low.  Tomorrow, I'll rechange the lower horn for the one 1.5mm longer to see what it does.  I'd like to get a pretty constant tension up to the upper elevator movement limit.  If really needed, I may consider remaking stabiliser attachment brackets to make it higher (and therefore reduce the bend of the cable on the fairlead). 2.00
03.03.25 I made the lower connection to the elevator and adjusted the cable tension. Problem!  The tension increases when I pull up the elevator to the point I cannot lift it to its upper position.  I found that the distance from the upper horn hole to the hinge was smaller than the one for the lower horn hole (99 mm vs 101 mm).  I Made a new lower horn to correct this.  Better but still not perfect.  I made a third horn with a distance of 97mm.  Now, the tension varies between 25 and 40 lbs over the range of elevator movement.  Called Chris Heintz (when the range was from 20 to 60 lbs--second horn) and he said it was acceptable.  I elected to make a third horn anyway.  I wonder if I should make a fourth one... 8.00
03.03.24 Made rear rudder cable attachments.  I elected to use the turnbuckles positioned behind the seats (as I did for the elevator).  Also made the upper elevator cable.  This elevator cable may be a bit too long.  One of the rudder cable is also long (requires a lot of adjustment turns from the turnbuckle). Measured rudder deflection at 21.06 degree (!).  Called Chris Heintz about rudder deflection (see rear fuselage log entry) and he said it is OK.  He also confirmed that my splice plates are OK. 3.00
03.03.19 Put brake fluid in brake lines.  I had a hard time to bleed all bubbles out, but it appears to be OK. 3.00
03.03.11 Installed pedals, push rods, throttle torque tube and throttle push rods. 2.00
03.03.10 Completed throttle control assembly.  I went to C. Guilbeault to have my SS throttle pushrod reinforced (I had a reinforcing piece of rod welded where the assembly wanted to spring).  Painted the torque tube, small parts, Ign support, pedals and more.  I still have to clean up the cuts I've done on the carburator and I have to deburr the firewall where I drilled holes. 8.00
03.03.04 Worked on throttle control. 4.00
02.10.30 Installed grips and PTT on Y control yoke 1.50
02.05.22 Secured aileron control cables at torque tube. 0.75
02.05.01 Installed cable guide on middle bulkhead (+ primed bulkheads) 0.75
02.04.29 Installed brake line of right side. Modified brakeline support on left side.  Made a skin patch on right side. 2.00
02.04.28 Installed turnbuckle on lower elevator cable 1.00
02.04.27 Installed turnbuckle on upper elevator cable 2.00
02.04.14 Made and installed aileron cables.  Also made the two openings for rudder cables in rear fuselage 5.00
02.04.10 Had thimbles inspected. They are fine. 0.50
02.04.09 Installed thimbles on rudder and elevator cables. 1.50
02.04.02 Installed master cylinders (cut bottom support to fit + cut one of the master cylinders rod). 2.00
02.03.04 Installed center pedal support 1.25
02.03.04 Some of the control work was done in forward fuselage assembly (or Center wing… can't remember).  That work was the installation of aireron bellcranks, torque tube, center stick. 0.00
01.04.07 Sand blasted and epoxy primed steel parts 4.00
01.04.01 Welded nose gear push rods, engine mount fittings.  Changed bolts on nose gear leg for longer ones.  Threaded all rods. 5.00
01.03.23 Had torque tube welded.  Made one engine mount attachmetn bracket 3.00
01.03.18 Made torque tube parts… almost ready for welding 3.00 Torque tube
01.03.17 Completed pedals on jig (yesterday and today). I brought that to the welder and he told me that having the brake attached to the floor instead that on the pedals makes it a more natural pedal movement… anyway, it it too late. 10.00 Pedals
