However, it’s a royal pain in the ass to install the rod ends that connect the rear legs to the top of the rear hoop. I’ve removed/installed the cage many times and it’s a pretty quick and easy process. My takeaway for titanium is that in addition to material the tooling and machining costs are noticeably higher. ![]() With tools, my general philosophy is “buy once, cry once” and while McMaster charges a premium, I get it one day and I don’t need to worry about quality. Taps designed for titanium have a different coating and spiral flutes, so I ordered a $47.17 tap from McMaster. ![]() NFW was I going to finish the hole without breaking the tap.Īpparently, titanium’s low modulus of elasticity makes it “springy,” so the workpiece tends to close in on the tap causing galling and tearing of the threads which also increases the torque on the tap. After replacing it with one specifically designed for titanium, I quickly determined that my tap was a no go. A piece of 6” long by 1/2” OD Grade 5 titanium rod cost me $33.85 and part way through drilling my first hole I wrecked a high-quality, made-in-the-USA drill bit. With aluminum, stainless steel or 4130, I’d have the material laying around and the machining would be straight forward. ![]() I fabricated threaded 1/4”-20 bosses from 1/2” Grade 5 titanium rod. ![]()
