And if this titanium fails, try PH 13-8 Mo precipitation hardening stainless steel (UNS S13800) in H950 or H1000 condition. And if _that_ fails, switch to MAR 250 or MAR 300 maraging steel. Because, while titanium is great stuff, weight of the part isn't really critical. The excellent strength-to-weight ratio of titanium isn't really needed, you need outright strength. Actually, guessing the application, you need strength and *fatigue cracking resistance* for this part to survive. (Metallurgist/Materials scientist & engineer here)

[@CatNolara]

Exactly what I wanted to point out. While titanium is a nice material it can't compare to steel alloys when it comes to strength.

[@gerrylundergaard60]

It’s a pretty simple solution to use a 1070 alloy or a 301 stainless here to resolve the failure issues here. But unfortunately from what I’ve seen from the authors skill set he would not create a proper lead out to minimize thread undercut. Used car salesman here who was a cook in the Navy. I did spend my free time learning from the machinist mates in the maintenance crew.

[@gerrylundergaard60]

@@cole4406 301 achieves its properties from cold working. It is not heat treatable. It is a great choice in small diameters for its fatigue resistance and corrosion properties. That’s why it is a choice in springs. The weak link is in the thread formation & blend termination. Radii go a long way here too.

[@davewood406]

I was thinking the same. Titanium sounds sexy but it's a strength to weight application. Like another poster mentions, I am betting the failure in this application has more to do with how the previous axles were made rather than material properties, Assuming the dimensions Adam was given were correct, I wouldn't be surprised if just making them properly might solve the problem.

Back in the "dangerous old days" we always had a barrel or two of carbon tetrachloride around for clean-up. I, personally do not know of a better cleaner than carbon tet, but those days are gone.

I think I understand. It's the rpm that determines the fine or coarse thread. Maybe I'm wrong but if it clamps onto the feed rod, 4 threads per inch, it must be, in my old brain, the feed rate n rpm would give you what you want. I'm an electrician but watching you n Steve summers, it's just a pleasure watching. I hope I'm close on how I THINK it works. Thanks Adam.

[@miles11we]

No the rpm of the spindle has nothing to do with it. Its the relationship between the spindle and lead screw, so the gear box will change that relationship allowing different threads. You can turn them at whatever rpm you want

If those titanium axles break or bend (and I suspect that they will; there's a lot of misconception about the "strength" of titanium), I would recommend remaking them in 4340 with a heat treatment to the low Rc 40's, and optionally a cryo treatment for even more toughness.

Titanium is good for planes because it has a high strength to weight ratio at high temp.

Best thing to do in such a case is to leave the half-nut engaged and reverse the lathe.

[@HaraldFinster]

Even the use of a thread dial when cutting metric threads on a metric lathe is a bit more complicated than imperial threads on an imperial lathe. You need different pinions in your dial depending on the pitch of the thread you are cutting. The reason for this is that usually imperial threads are given as fractions of an inch whereas metric ones are designated by distance between threads per revolution. I agree that starting the thread at the shoulder and working away from it is a good method. You need an undercut for this method though. An other trick is: disengage the half nut at the end of the thread, stop the machine and let it come to a standstill, reverse the machine and re-engage the half nut at the point where the thread dial lines up again. This method works for any thread pitch on any machine (metric or imperial). Adam once demonstrated this method, if I remember correctly.

Nice job threading those Titanium axles. I have to say that you make it look easier than it is. I don't know what grade of Titanium this is but I can tell you that some grades are far more difficult to cut than others. With the tougher alloy, using HSS tools can be disasterous. If you dont have a super sharp tool, your speeds and feeds are not right and you take too shallow (rubbing) of a cut - the HSS tool will dull. Next pass you will work harden the work piece and you might have to throw away the work piece and the tool. I think I saw a little bit of that action when after turning to the major diameter and cutting the 1st pass of the thread, you got a loud screech chatter and I could see the work piece flex away from the cutter. The second threading pass was much better - probably because the work hardening was removed by the Carbide threading tool at .005 depth of cut. Thanks for the demo.

It makes sense that if you always start with the tool at the same place along the cutting axis ,then the tool will engage the thread to be cut correctly.

[@natetallman]

I had a titanium wedding band. I got into some poison ivy and my fingers started to swell a bit, causing my finger to start throbbing. I called a buddy at the fire department and he told me that had tools to remove rings and to come on down. The ring ended up destroying two different ring cutting tools, so they ended up using a Dremel and had to cut both sides to get it off. All in all, it took about 45 minutes to get the ring off. Adam's tools make it look like butter, but titanium is insanely strong! It's only silicone rings for me now.

[@natetallman]

[@MF175mp]

You can probably get stronger steel for a lot cheaper but the customer is always right

[@jayreiter268]

Mf175 that was my thought also. Titanium also has a tendency to gall in the threads. We had to replace titanium bolts and screws on L1011s because of that.

[@buckhorncortez]

The modulus of elasticity for titanium is much greater than steel. Titanium recovers its original dimensions and shape much better than steel. So depending upon the failure mode of the previous axles, titanium might be the material to use.

[@CarbonKevin]

This is correct. Titanium alloys are stronger than steel by weight. However, we're constrained in both diameter and shaft length, so the right approach is to spec the material that is strongest by volume. So yes, some steel alloys are going to be far stronger than titanium for this application. If she's breaking steel axles, she's very likely going to break these - unless the stock steel axles are made from truly garbage steel and these axles are made from some truly high strength Ti alloy.
