I think I should check my enthusiasm for my new plane for now and just concentrate on the engines. :rolleyes:

I've never worked with Titanium. Can I cut it, turn it, and finish it with normal tooling?

I asked the same question - still waiting for George to answer. He did some great looking pieces

I know a LITTLE bit about working Ti. It works with basically the same cutting tools as steel but work-hardens like stainless 303 or 304 (really badly, it gets hard FAST). You need to drill using a pretty slow RPM (about 1/4 that of steel) but use LOTS of feed pressure. When I first made a drilling unit for a portable set-up for the 737 I set a 1/4" drill at 3200 RPM and low feed and real quickly I could read a book by the glow off of the drill bit. Cutting and milling is similar.

What about weight compared to aluminium

Thanks, Bill, for the info.

The only time I ever purchased any Titanium was when I was a kid. I had a mini-bike with a 2 stroke West Bend engine that I had ported and stuffed. It made so much more power that it keep ripping the rear sprocket bolts in two. I purchased 3 bolts - I think I had to mow 3 yards to pay for them - but they never failed. Too bad I didn't know about grade 5 bolts. It would have saved me a bunch of money.
