Is a metal band saw a must for building a RV8?

I did not use a band-saw. I was able to cut all the heavy gauge aluminum angles with a good quality hacksaw and fresh saw blade. One of the main reason for not purchasing a band-saw is the limited shop space of my small garage. All of the cuts in the RV8 are straight line cuts and you have to round off the corners with a file and final finish using the 3M wheel.

I wouldn't say MUST, but it is very handy. Fabricated angle brackets, stiffeners, etc. are a breeze on a band saw. for the price of a cheap one, I'd say you'd get your money's worth

And you don't need a metal blade. I'm building an RV-3B, which involves lots of cutting, and have a 6.5 tpi wood blade on mine. It's a bit coarse but sure cuts nicely.

I smooth the cuts on a sander and then finish them with a Vixen file. Quick and easy. However, wear a mask with any power tool that does fine work - sander, Scotchbrite, whatever - because they make aluminum dust that floats in the air. You can sometimes see it glitter in sunlight.

I used a Delta scroll saw with my slow build -8. Not as good as a band saw but it worked fine. Use lots of Boelube and you'll do fine either way. Slow blade speed works the best IMHO.

Maybe not absolutely needed, but you're going to be building a $100K plane (at least). You might as well spend $150 on a bandsaw that will easily earn its keep over the life of the build, and then some.

And I would recommend an 18tpi blade--will work better than a wood blade--cuts cleaner and straighter. It too only costs $10 and is easily changed so why not?

I didn't have on on my build, but if I ever build again, I'll get one. And about a 3' break and a lathe and a vertical mill, and and and..... My advice? Get one.

All the band saws that Iíve been looking at are made for wood. What brand and model are you guys using?

Whatever you can find at Home Depot or Lowes will work fine. It's the blade that matters more. That's easy to swap out.
