Good job helping out. These things mean a lot for some people.

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)

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.

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. But for this application, he would probably get higher strength out of an alloy steel, like 4340 heat treated and tempered. It would just be heavier than Titanium, but that should not be an issue for a skateboard.

Thanks lots for the lead screw indexing information, I've been cutting single point threads for decades now, waiting for that one number on the dial to line up, no matter how many times the thread pitch is divisable by the lead screw pitch (4)...

I look forward to seeing the thread cutting video. In my opinion there are few turning operations more satisfying than single point threading. One aspect that people seldom mention however is the gear that drives the threading dial also has to have the correct tooth count for the pitch being cut and some lathes have set of gears for the thread dial indicator as well as the change gears for the lead screw.

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.

Glad you are helping out

Thanks for share the story about the young girl. Does make my heart happy. My aunt was a special Ed teacher in the school I went to and I have a special place in my heart for special needs children.

Ti is an awesome material for axles. wicked lite and unbelievably strong. It does gall easily and it's recommended to use a good anti seize on the threads. now for some Ti nuts to go with them. :D

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.

Usually becasue the king-pin would get caught in some uneven surface, and the 80-100kg of weight pushing it down and forward to snap it. I'm sure if you jump on these things, which I didn't do that much, the axles could also break. A more "springy" and strong material would almost certainly be preferrable, which is where 4140 and similar types of alloys excel. Scooters, which I think all these are for (they are way too short to be axles for trucks) would have much more load on a single wheel, as there's only two wheels, one at either end, so quite plausibly part of the problem.

Thanks for your efforts😎🤗😎🤗

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.
