There are 2 types of firewall eyeball pass thru for control cables.  One 

mounts with 6 small screws, the other uses just the single large hole.  

Can some one tell me what size hole the latter type requires?  Van's web 

page says 1.115", but that's such an odd size I suspect it's a misprint. 

If not, what did you use the make the hole?  How much over size can the 

hole be and still be usable?

Tom,



It is an odd size, but it matches up with a standard electrician's

conduit punch.  I've included some of the sizes I could easily

find.



     * 3/4" Conduit Punch, Hole Size: 1.115"



     * 1" Conduit Punch, Hole Size: 1.362"



     * 1-1/4" Conduit Die: Hole Size: 1.701"



     * 1-1/2" Conduit Die:, Hole Size: 1.951"



     * 2" Conduit Punch: Size: 2-3/8 2.416"

You can find these on eBay, or try to borrow one.  They are

kind of expensive.

Mickey:

    I was hoping to hear an answer like that, thanks.  We've got lots of 

those at work. I can probably borrow one for a weekend.

I did three of these last weekend on my RV-7A using one of the larger Irwin unibits that I was able to get off e-bay for about $23.  The unibit made it through the stainless firewall ok on the first hole, but the 2nd and 3rd holes were tougher and I had to go slow with some short breaks  to keep the temperature down as the holes got big.  Another thing you can do in a pinch, is use a slightly undersized  unibit (Costco in my area had them for up to 1 inch diameter) if thats all thats available locally and finish it off by grinding with a Dremel.  A circle template is usefull to guide your grinding in this case.     



You might be able to oversize your hole slightly, but not very much, as there really isnt that much overlap by the eyeball fitting.



Good luck
