Chap. 5 - Side Jigs

Recommended Posts

Chapter 5, page 2 of Cozy Mark IV plans show the max width of FJC to be 5". On the same page in the AeroCanard SB/FG manual, it shows this measurement to be 3", or 2" shorter, to account for the widened rear.

 

However, the max width of FJE (for the lower part of the fuselage) is 6" for BOTH plans. Shouldn't this measurement be reduced as well, also to allow for the widened rear?

 

Unless I'm convinced otherwise, I am planning to use 2" shorter here as well.

 

Edit: Another way to "see" this, is to know that both the upper and lower longerons are moved out 2" each, so why not the corresponding jig angles?

Look again Jon. The drawing I'm looking at, (downloaded when it was legal:) ), shows the FJE to be 6.0 for the SB (Cozy) and 4.5" for the FG (AeroCanard). Didn't you get the memo?:D

So, don't go 2" shorter, go 1.5" shorter.

Wow! I just looked at my electronic version -- there it is 4.5"! Also interesting how the both versions only show the 3" AeroCanard FG measurement for FJC, without reference to the AeroCanard SB (Cozy Mark IV) measurement of 5".

 

Concluding, we now know that the following are needed to build an AeroCanard FG from plans:

  • AeroCanard FG printed plans
  • AeroCanard electronic plans (or an updated printed version)
  • Cozy Mark IV plans (to translate the poor OCR)
To top things off, I understand that the landing gear bulkheads will need to be cut down some during assembly.

 

Still, I'm looking forward!

Here's another measurement: The firewall moves the upper longerons out by exactly 2.5" on each side.

 

I'm going to use the 2" adjustment, so I can bend anywhere between 1.5" and 2.5". Should be fine.

Jon,

 

Glad to hear you're back at it!:) (The bottom is on the fuse, it looks really cool!):D

 

Just build it like the plans say, it works out. (The only problem was the aft lg, and the plywood in Chap. 7. I hope to have it figured out for you when you get to that point.;)
