Title: Old time
Post by: Dwayne on March 28, 2008, 06:00:28 PM

You know talking about Incedence meters and all this and howabout  that. How did the old timers build there models?!! The old I beemers!! and what not! The Neptune , Detriot Stunters and on and on! Aweseome airplanes and most of them had no plans!! They just built them from scratch!!!! I wish someday I can do that!! I wish!!

Careful measuring.

Watch Hunt's video on building I-Beams.  Of course back in the old days it was a secret.  DOC Holliday

Yeah Bob Hunt!! He is one of the greatest!! No question! Bob Hunt is one of the greatest!!  But when it comes to building I beems Bill is the one!!!!

If you had a large flat surface, I-Beams were the easiest of all to get a straight model from.  Everything was its own *jig*.  Still my favorite style of building when I actually do build! LL~

Also another of Bob Hunts video is the building of a lost foam wing.  A lot of detail on how to do it.  The easiest way is to get the set of wings from Bob.  Best bet is contact Bob.  DOC Holliday

While the incidence meter can help, you can probably measure closer.  Case in point: Can you measure within 1/16"  if you are locating the wing onto the fuselage and make a 1/16" measurement error on a 10" wing chord that results in an error of 0.35 degrees. that is closer than you can see on the "needle" type incidence meters.  The digital type - maybe you could do better.

Of course if you can measure closer than 1/16"...!

On a 3" wide stab  (w/o elevator) a 1/16" error is 1.2 degrees.  You would surely see THAT with a meter, but again the needle type would be hard to completely see the correction!

Of course, meter or not the best way to assure alignment is with a flat fuselage top and a flat building board!
