I made my first wing rib tonight!  RR#1...  It turned out great!  =

OK for now, I'll just hang the scrap rib on the wall as a reminder... =

BUT, I'd like not make the same mistake again...



Can anyone point me to a good hole/fly cutter to do this job?



Thanks in advance,

Thanks all,



I just purchased another one, this time what looks like a more sturdy built 

one with carbide cutting blade...  We'll see how this works out...



Thanks much,

Randy,



I had unpleasant fly cutter experiences too.



I found plain old tin snips to do a reasonable job.  I start by 

marking the finished hole line.  Then I use a step drill to make a 

hole big enough to start cutting with a nibbler.  The nibbler cuts to 

around 1/4 inch from the line.  Then normal snips cut close to the 

finished line and a combination of rat tail and half round file 

finish the job.  I takes longer to tell the procedure than to do 

it.  A final pass with file and/or emery cloth deburrs the hole.



Have fun,



Paul

 spar web and the tip spar. I haven't done it on the

 ribs yet, but I am sure I won't have a problem. 

 Make sure you clamp the piece securely. My latest

 desire now is to flange the holes. I am working on

 a tool to do such a job using a drill press. I have

 2 sets of nylon wheels spinning around in the press

 and as you apply pressure it should bend the flange

 evenly around the edged of the hole. Haven't tried

 out yet, still tweaking the tool to get it working.
