Beg, borrow, rent or otherwise obtain some chassis punches or conduit punches to do the holes. Edge lipping the punched holes helps in the rigidity (over just a plain cut hole). The Fly cutter will hurt you, especially doing hundreds of holes. I did a wing set via the punch and a battery drill on slow to operate the punch. All done in one evening I recall, and the edge lipping of the hole worked out.... ....................................................................... .....

First, mark all the centers carefully and drill (not with the fly cutter) 1/4". Drill the ribs undersize and ream to 1/4" if you have a reamer. Fit the fly cutter with a 1/4" SMOOTH pin NOT a drill bit. Grind the cutter blade to a narrow cut, about .050 at its outer edge. Use only about a 7 degree clearance angle. Set up a sturdy board clamped to your drill press table and drill about 15/64 and then "burn" to 1/4" with a smooth pin. A few drops of oil in the hole will help. This will give a firm outboard pilot for fly-cutting. Now mount up your fly cutter and float the SMOOTH pilot pin into the rib hole and into the board. Clamp the rib to the board and only now start the drill press. Use rather slow speed, but you may feed quite firmly until near breakthru. A touch of oil will help but is not always needed. This makes fly cuttin a piece of cake! Good luck,. Paul S.

What makes it particularly hazardous to RV builders is that the project may be the first time a fly cutter has been encountered by the builder. True, common sense will dramatically reduce the odds of an accident, but when a fly cutter and the material being cut gets loose, the results can be catastrophic. Somewhere on the web a few years ago a photo circulated of a mangled hand that had a most unfortunate encounter with a fly cutter. The points presented in Paul's post below are certainly valid and detail a great way to tame the fly cutter. In my experience the two most common errors in using the fly cutter are failing to TIGHTLY clamp the piece to the drill press table with a wood backing and failure to use a SHARP fly cutter. If the cutter gets dull, it WILL snag in the cut, hopefully stalling the drill press, but if the work isn't tightly clamped, and the drill doesn't stall, the whole deal becomes a whirling guillotine. Another hazard is failing to stay clear of the cutter. Depending on the speed of the drill press, the cutter bar can be nearly impossible to see and dangling clothing or careless fingers can instantly be pulled into a really bad situation. Yep, a fly cutter can be used with a hand drill.....I've done it when needing to add a hole to a panel in an assembled plane (didn't enjoy the process, however), but this only increases the possibility of having an accident. It is easy to let the cutter get less than perpendicular to the work and then there are problems (see above). So, be careful, work slowly, keep the work securely clamped and the cutter sharp, and all should go well. Violate any of these guidelines, and your building progress may be uninterrupted while you learn to use fewer fingers. Let's be careful. :-) Sam Buchanan ======================= Joseph Larson wrote: > > You know, I never had a problem with my fly cutter, and I was a lot less > cautious than this.

I did my smaller holes this way. I didn't have large enough punches to do them all. The rib material is thin enough that it goes pretty quickly with a fly cutter. On a Van's kit the ribs have pressed in raised rings that you leave in place when you cut the lightening holes out leaving you a nice reinforcing flange. I also used a punch to do my conduit holes. That made short work of those and it leaves a great hole without a burr.
