Cutting bulkhead for radio tray

dreed

Well Known Member
Hi All

Adding an IFD540 to my panel soon and looking for tips on cutting the hold in the secondary bulkhead behind the panel (RV-7A Slider) for the long tray.

Why re-invent the wheel with all the smart folks on here... right?

I plan on four holes in the corners, but then a saw? Nibbler? Anything better?

Thought about clamping a piece of wood in there to dampen vibrations if I go the saw route.

Thanks in advance-

10 years ago I used a nibbler which sprayed tiny chunks of metal everywhere.

Today I'd use an OMT -- oscillating multi tool with a curved-tooth bimetal blade. And definitely drill holes in the corners first.

This style blade: https://www.amazon.com/Bosch-OSL114F-3-Starlock-Oscillating-Bi-Metal/dp/B01DDA7VU0
Or this one: https://www.amazon.com/Bosch-OSL312T-Starlock-Oscillating-Segmented/dp/B01DDA7VV4

We called a Multi tool a "Wig-Wag" in the plumbing business, and the best blades you can buy are Diablo Carbide:

Something fine toothed makes the smoothest cuts.

Used my Dremel. It's my first choice for most things, but I'm a dentist, so I'm biased!
