    Excellent. You mentioned adding weights in case of vibration. I guess I'll have to look up videos that show that, but your video shows the depth of knowledge machinists have from experience. Truly remarkable. I have 3 college degrees and I greatly admire the acumen level displayed by so called "blue collar" workers. It definitely rivals people with degrees, as many I know that've gotten through college are dolts.

    • @machiningmoments

      You would need a chuck with t-slots cut into it between the jaws. Weights are added to the slots and moved towards/away from center to find balance. I've been fortunate to work with some really gifted people and I've learned a lot. Young people have a lot to teach with technology as an example. I always tell my students "we are all teachers". Thank you for your kind words.

    Ever since I took a university course that involved me in using machining tools I've always wanted to work with them again (never had the chance since covid hit). This was one of the unanswered questions I had since my part only required a 3 jaw chuck, I had no idea how to dial in anything that isnt round or off centered. Great informative video!

  • @mechanical1955
    @mechanical1955 Před 8 lety +7

    Great way of doing it , in the toolmaking trade we use a small fixed centre between the rotating centre and the centre drill hole and index off this so it wobbles the same , save making the tapered tool you have made and they are hardened steel and will last forever
    Nice one same principal , Keep up the good work , Alan

    Little trick I use is to chuck up the dead center in the tail stock, lock the stock, and while holding the plate, with the jaws open enough where they don't interfere, introduce pressure with the tail stock until it presses the metal plate against the jaws. You then lightly tighten the jaws, and proceed exactly as you did. The advantage is, it gets you a lot closer to center quicker, making less adjustments to the jaws. Just a time saver.

    Good to see fella. Not many would think of that but merely put their center in the drilled hole. I was taught this method by an old turner I met in a unit where I worked after getting my old Myford super severn. I made my bar from ground stock. It is the best way. I was trying to tell a newbie to lathe's friend the other day and I said I bet there is a youtube video on it and better than me trying to explain it if you don't know the terms. Then I found this so I'll Link it to him. Thanks for posting.

    Use a lever type dial indicator and adjust hole towards the center by halving the total reading. You can get it very close to true by using the center (light pressure) to hold the block when you start and then bring the jaws in until it touches the block. Then use lever type dial indicator for final setting. Always works and is quick!

    You did that pretty fast! I recently bought a centering microscope that will fit the tailstock or the mill spindle. You video makes me think "why do I need the centering scope for the lathe, after watching this?" But I guess it will stil come in handy on the mill with a rotary table or the dividing head when I have a four chuck on them for milling, boring, drilling odd shaped or eccentric pieces (and that DOES happen from time to time in model engineering, like scale locomotives and such). Thanks!!

    • @machiningmoments
      @machiningmoments  Před 4 lety +1

      @@Foxyjosh Good question. You need a chuck with a way to bolt a counterweight to it. Having t- slots in the face between the jaws makes this easy. Put your lathe in neutral the chuck will rotate to the heavy side...6 o'clock. Add the weight at 12 o'clock. I drill a hole in round stock maybe 3 inch dia. 2- 3 inches long (depending on how heavy your part is) slide it over a t- nut and stud and tighten a nut on the other side. Move the weight towards and away from center until the part will not move in any position in 360 degrees. It should be balanced. Watch your rpm, it is not meant to turn fast. Watch your fingers there is a lot going on with that chuck face. Good luck.
