I was at the dentist this morning.  Looks like I need a crown.  Dentist makes the crowns in house using a milling machine, so I asked to see it.  Lying next to the machine were a bunch of these bits.  He said that they are one-time use and he was gonna throw them away.  Instead, he is happy to give them to me.

Hmmm...now wondering how I will use them.  They seem like great little routing bits. 

This dentist is new to the practice where I have been going for 30 years.  He is taking over for the old guy I have seen all these years.  He is young and we seemed to hit it off pretty well, so I will see what other tools they have to discard that I might use.  @HectorLooithoughts would but of interest here.

These are all the new digital toys. The next generation of dentists will practise a totally different brand of dentistry.

Starting from the moment you approach the clinic, facial recognition software will alert the staff as to who is coming. You will be greeted by your name.

Before you even sit in the dental chair, a series of digital xray scans will be taken.

Next, an intra-oral scan of your mouth will be taken. Diagnostic software will merge the xrays and optical scans and do a full analysis of your dental condition, from gum disease, tooth decay, crooked teeth, buried wisdom teeth, etc.

If I were going to work another 10 years, I would consider going full digital. But as I'm planning on retiring soon, I can only dream on.

Imagine what can be done on a quite day with such toys... Scan a broken part and 3D print the part in metal! Mill your own watch case out of a block of zirconia and fire it in the furnace. 🤤

I have a handful of these. I chuck them up in my Dremel and used them for inlay on guitar/bass fretboards. Works best in harder woods, and on the inlays themselves (metals and shell mostly, occasionally bone) and only for really fine detail/cleanup.

Yeah, I chucked one on to my dremel and etched some glass.  Your application is a good one.  I play my guitars...rarely have to mod or fix them, but these will be in my back pocket if I need to.

We use similar bits quite often. Longer and more slender, but almost the same.  Very handy for touching up the sides of a set bridge after hardening and tempering,  removes the blue and machining marks. I could see a dental CNC machining molds or mold forms with them, maybe some ceramic?

I make them. Or used to at least... It's been a while for lack of usable shop space. I did repair in high school and college, but severe burn out put an end to that around graduation. Played quite a bit too. Got a sponsorship deal from a boutique amplifier manufacturer at one point, GC "artist" list (gear at cost discount), made a little beer money. These days, I keep a late-50s archtop strung and tuned for the occasional strum, but most instruments are slack in their cases.... Still have a couple "in progress" that may never be finished (seasonal movement popped the bindings off an archtop body, and I forget the status of the solid body electric), and a '67 Fender Deluxe Reverb I need to figure out the ailments of (picked it up for $25, and have another $50 or so in it at this point).

    • If at all possible, find a service guide for the automatic movements your work on, because the lubrication procedures may have different requirements or rely on oils you would not use in a manual wind train (in addition to the braking grease you mentioned). Some autos like older Seikos do not have a manual wind option, so the procedure of letting down the mainspring without being able to use the crown may require a screwdriver in the ratchet wheel screw and great care. Do you have an auto movement you were planning to start with?
    • I am an amateur, so there's that. I do not get fixated on amplitude, lift angles, and beat error. However, 4.8ms would bug me if it were my watch. But you must judge your own skills to appreciate the possibility of going backward. I suggest, that you button it up let your friend enjoy the watch for now. As your skills progress, come back to it and correct it. I assume that this watch has a fixed hairspring pin. Some modern watches have an adjustable pin along with adjustable regulator. These are trivial to get in beat. I own a valjoux 726 my dad gave me on my 18th birthday (a looooong time ago). I broke the ratchet wheel with an aggressive wind 4 yrs ago. I have been waiting for my skills to progress before doing a service. I am close. Your advice is well placed and I will apply it.
    • I didn’t find any anomaly to the left of the red mark…reflection? this is the balance in its pivot in the inverted assembly. i can’t see any obvious kinks  and the spring is flat as far as I can see. Either the stud screw is missing, or it’s glued in… I don’t know. I’m loathe to fiddle with it. Any further insights? Thanks!
    • Update!  I've dismantled it, cleaned all the glue off, and rebuilt and lubricated the base movement. I'll leave the chrono part for another day. It's running well - great amplitude and keeping time, but it's got a beat error of 4.8ms.    How important is it to correct this? I'm worried that the potential for making things worse having to take the hairspring off and on repeatedly to adjust this. Would anyone here accept it at that?
    • Since I've been banned from the previous discussion, apparently my language was inappropriate...for small boys. I will start another thread and act in a more decent manner for the girls and ladies of the group.  Please what will happen if the forum can't be managed by the administrator, are there provisions in place to preserve the achived member's questions and answers over the years. Please if I may ask these important questions that are important to the members please.
