    Nice... if only I had some titanium lying around like you do....

    I hate machining titanium... almost as much as inconel.

    I have a "market mirror stock".

    All the stuff that is easy to get, I have none of in stock.

    All the hard to come by materials, you name it, I got them all.

    Hey, it seems I broke the cycle of bad karma.

    The inserts for the head tube, were hidden inside a piece of aluminum I had laying around

    This officially makes this project ahead of schedule, as I have made the bearing mounts for the seat tower and the shock as well.

    EDIT: that pic needed something for scale. They are for a 2" head tube.

    I just machined the biggest rear through axle I have ever seen.
    14mm diameter, 185mm long!

    I still lack the fittings for it, so no pic yet.

    Here is the finished 14 x 180mm through axle.
    I made the titanium hex insert today, and glued it in.

    For scale is the 160mm Hadley hub it's made for.

    Sweet Stuff;

    I'd like to be able to do that, but I don't have the knowledge, I know, nor a capable machine, I don't think. Between me and Old Floppy, we make some pretty grody looking stuff.

    I noted when I blew it apart to polish that my new Salsa by Formula front hub had the adapter bushes on the ends to make it a 9mm QR, but had a pretty large bore on the actual axle. Makes me think about machining projects.

    Please continue for the vicarious machinists among us.

    A lathe by any other name, is yet still a tool, after all. It's really a question of end play.

    Darn it, Magura. Now you have me wanting to put discs and a rear derailleur on the kids' BMX. LOL.

    With the skills you hold, and the toys you have, that ought to be a nice project, no?

    Care for a 40 hole blank?

    I was just thinking about how to make a 20mm through axle and thought I couldn't without broaching an allen hole. Can you explain how you glued the insert in?

    Thanks, Joel

    It's threaded and glued in, using Hysol 9466.

    EDIT: After thinking it over, I don't think you can use this method for a through axle for the front, as you need considerable torque. In my application, it's just for a limited amount of counter torque.
    Broaching a hex in aluminum, is fairly easy to do. If you machine a hex and harden it, you can just press it through the aluminum. I do that a lot, though I usually grind a hardened rod to hex shape, but the principle is the same.

    Hey, is that an RC control propping up that frame? ....next to that battery pack?

    Didn't know you were into R/C.

    That pic is not from y place, so not my plane (plane peeking through the door), but besides that, you're right.
    I like RC Marblehead yachts though, and build such myself.
    Think composites

    I bloody well hope so

    This project is on the wrong side of 200 hrs. by now, and still in need of another 100 hrs. I guesstimate.

    It's a hobby. A couple hundred or thousand hours doesn't matter.

    Well, you know, I have other hobbies to tend to

    I did the math btw. for your suggestion to use PTFE for a plain bearing headset.
    I had actually guesstimated it to be far off, but it turns out that it's within the surface load limit.
    Thanks for the heads up. That's sure the next project to fit in this frame.
