 |
|
I made my cutting templates out of 1/2" plywood. I
found that I could cut four ribs at one time without
any major problems. They turned out pretty well for
the most part.
If you are going to router cut, make sure you use a
good quality laminant bit. Mine was a cheaper one and
the pilot bearing came off and nicked my nose rib
cutting block. Not a major issue but all of my
remaining nose ribs had a small defect on the back
flange (not a structural issue).
Additionally, I found that it worked best to take
smaller cuts. Any deeper cut than about 1/2" caused
more vibraton than I was comfortable with. If you
have to cut deeper than that, just do it in multiple
passes. I rough cut my blanks with an olfa knife and
some use of snips.
Be sure to wear proper protective equipment if cutting
with a router. A router table seems to work best and
a vacuum as a chip collector. Make sure you wear
safety glasses and hearing protection as this
operation is very loud.
Best of luck with the build

Scott,
Yes, I was thinking about making rib cutting
templates like yours (yours are
for a CH601, correct?). Could I make the templates
a little thicker and use
a laminating cutter bit and router to cut the
aluminum blanks? I think I
saw that in the "Scratch Building Basics or Metal
Aircraft" DVD.
