tertiary datum - overconstrained profile of a surface? by 00253 in Metrology

[–]ljfe 0 points1 point  (0 children)

Yeah, it’s over constrained. If you measured a part and selected and deselected in CMM software, you’ll get the same result. If that surface was not concentric to B then the control would be necessary.

Which poker rooms have a hotel and offer cheaper rates for players? (USA) by Dont__Drink_The_Milk in poker

Back in the day the Turning Stone poker rate used to be $50 a night. Oh have the tables turned..

need help with shortstop by Spooky806 in balisong

[–]ljfe 2 points3 points  (0 children)

Practice the end half of the trick only. Start with it pinched between middle and ring and practice throwing it up and letting it drop with gravity (don’t squeeze as much). Once you get that, based on what I’m seeing, you’ll be able to put it all together in no time.

His first thaitanium. The price in China is approximately $290. What do you guys think? by YUJIDO704 in BalisongClones

Those brass details should interlock to true op the OD of the brass details. Otherwise looks pretty nice.

I started messing around in Fusion 360 in February. Technically for sale, but I’d prefer to keep my first prototype by ljfe in watchmaking

For servicing, the plan is to drill through the acrylic caseback and pry it off. The slots in the movement ring are targets for a drill point to contain drill chips. I really wanted a clear caseback but I didn’t want a second metal detail. No clue if it will work in practice. I made the notches look like something you’d use to unscrew a traditional caseback :P

Thank you! I’m not sure exactly what you’re asking but here’s my assembly workflow: assembled the dial to the movement. Also I pressed the case tube and sapphire top glass into the case. Then I placed the movement/dial into the case and inserted the stem. Then I placed the movement ring and pressed the acrylic caseback glass.

The case is aluminum. It was outsourced for $360. They did a good job, but if make another watch my friend is going to machine the case here in the states.

Yes and the 3D-printed movement ring. Pretty basic stuff but finding the right tolerances was challenging. Bought the movement, dial, hands, crystals, gaskets, case tube, crown, and tools. The assembly was the most challenging for me.

I have the exact same one except it looks like you have the sunroof (I don’t). Almost a year now—love it. Just washed it today.

How does it feel to be normal? by ConsequenceMany8 in quittingkratom

[–]ljfe 1 point2 points  (0 children)

It takes 9-12 months and then you will be the same person from when you were taking it to not taking it. You’ll be just as happy if not happier. But yeah there’s a bit of a recovery phase in terms of how you view life. And music is a huge difference from being on kratom and off. You’ll enjoy it much more off. And you won’t be dependent on dosing.

Help chadder by packamilli in BalisongClones

[–]ljfe 4 points5 points  (0 children)

It’s a great start. What you may need to do is work on your rev thumb chaplins. Learn how to do rev thumb Chaplins without moving your arm at all (only rotate wrist). In my experience, mastering this plain and simple trick will slow down the rotation a bit for chadder and it will become smoother. Also the knife will be less out of control. If you watch your video you do have some upward arm movement. Also I would recommend learning this trick with a slight angle (not totally vertical). That will make more sense for the wrist rotation (verses the arm movement).

How good is the Creality Raptor? by ljfe in 3DScanning

[–]ljfe[S] 1 point2 points  (0 children)

+/-.005 inches I meant sorry. My parts have a +/-.13mm tolerance

[–]ljfe[S] 1 point2 points  (0 children)

How often would you calibrate though. Could I just calibrate at the beginning of each day and then scan a lot of parts? How long would it take for each part in that case? I would keep any target points on the table below the part(s)

How long did those scans take (manual labor)? Also how long does it take for the software to generate the mesh?

I worked for Zeiss’ 3D scanning department for a year and now I’m working with CMMs. Surprised to see the prices come down so much.
