Looking for direction on cutting...
Could I get some advice on how to go about cutting the excess metal off the R-710 Rudder Brace Horn. It won't go through a band saw, it's too thick to snip. Any advice would be appreciated.

Typically on situations like this, I use a cut-off wheel in a Dremel or die grinder. Wear eye protection and be careful.

As Mel suggests, I used a Dremel with cut-off wheel but not right up to the line. Then, I finished it with the bench grinder.
Cheers,

Another caution; try using a belt sander instead of bench grinder. Grinding wheels and aluminum don't play well together.

A bench grinder is fine if you use a (3M SCOTCH-BRITE DEBURRING WHEEL) or something similar.

You do not need a parachute to skydive. You only need a parachute to skydive twice.

+1 on the dremel. Cut it with plenty of extra.
I so have a big electric right angle grinder for cutting get thick stuff.
The Harbor Freight tools work fine.

Piling on to the dremel bandwagon. I use these wheels:
https://www.amazon.com/Dremel-EZ406-...s=dremel+metal
The ones that come in the dremel kit ("409 cutoff wheels") break easily but these seem quite durable - I've had good luck with them on fiberglass also. SAFETY GLASSES / GOGGLES ARE AN ABSOLUTE MUST when using these wheels.

Ditto, but the House of Balsa 2 inch wheels are easier to use since the body of the Dremel gets less in the way... 
Web search for "House of Balsa Tuf-Grind 2"

Yes, thank you. I forgot to mention that I used the 3M scotch-brite wheel. I've started taking it for granted that that's what we all use.
