I cannot find a good location for a compass except up high on the  

canopy.  Has anyone successfully mounted a compass up there?  I don't  

really want to drill a hole, but I'm also unsure of how I would glue  

a mount to the inside of that curved surface.



Alternatively, has anyone de-magnetized their instrument panel area  

successfully? Does this procedure involve any risk to the radios or  

gyros? Or other equipment? Is it necessary to repeat the de-gaussing  

from time to time, or is it a once and forever solution?



Thanks in advance

I had the same problem, I tried mounting a regular aircraft compass in  

the panel and on top of the panel and could not get it to zero in  

properly. One day I bought a compass at Meijer for $10 for my Jeep. I  

followed the instructions and had it zeroed out great stuck to the  

windshield with the suction cup mounts. Then I decided to try it out  

in my Zodiac. I stuck it to the canopy with the suction cups about six  

inches above the panel and was able to get it zeroed in just fine.



My regular aircraft compass was a Hamilton vertical card type. It  

probably would have worked in the same location but I figured it was  

too heavy and awkward to mount there. So I sold the vertical card  

compass on eBay and used the 3M double sided adhesive tape that came  

with the Meijer compass to permanently affix it the canopy. It's been  

a over year now and I've had no problem with it.



The Meijer compass is an Airguide brand similar to an aircraft whiskey  

compass. It is marked with both the eight cardinal directions and in  

degrees. It only weighs a couple of ounces. It is mostly installed to  

comply with the FAA requirement for a magnetic compass, but it works  

well enough to navigate by if necessary. I usually use the GPS for  

navigation.

Grant--

    Due to interference from my GPS I also had to move the compass from the top of the panel to the canopy. I used double sided foam tape(pads).  I did find after the plane sat for five days in the sun at Oshkosh that the compass ,due to its weight peeled away from the tape, however, the tape remained on the canopy. I subsequently found that if you add some instant glue(ZAP etc) under the compass side of the pad it gives enough strength to not peel away in the heat of the summer.

  

 Good luck

Grant,

 I mounted my vertical card compass on top of the  instrument panel, centerline.  I used the two small bar magnets found in  the base of GPS antennas and placed them at the base of the compass on the top  panel skin on both sides.  They worked to "neutralize"  the mag  flux in the area of the compass.  I was able to swing the compass ok.   

 Prior to trying the small bar magnets (I used  aluminum tape to cover them and painted over the tape), there was no way I  could swing the compass to agree on all cardinal headings.  Panel with  compass is shown on the yellow airplane at http://www.zenithair.com/zodiac/pic05/493tg3.jpg

I mounted my vertical card compass on top of my panel, center in my

CH701. It is dead on N/S and nearly so E/W. Just prior to final assembly,

I removed the entire metal cabin frame and took it to a TV repairman who

had a large, homemade degausser. After that I reinstalled the cabin

frame. At the time, I doubted it was worth all the effort, but now that

I'm flying with it, I'm glad I did it. I read somewhere in the list

archives to never degauss near radios and instruments, so that is the

reason I removed the cabin frame.

How about a curved aluminum tube that runs front to back, that follows the contour of the canopy, and then mount the compass on that? Might even provide some measure of rollover protection. Not much protection, but a little, especially if you ran another section side to side and connected them.
