    In machinist school I learned to use the tool post on the cross slide as a tail stock quill stop. I would touch off the drill to the end of my part to zero the drill. Then, I'd bring the cross slide over to the tailstock quill with the tool post touching the quill. Then I would zero out my DRO, move my cross slide to the depth that I want to drill and used it as a stop. 100% accurate and repeatable results all the time.

    I've got a few tailstock tools that eject right at the very bottom of travel. You have to almost jam the handwheel to get them out. I've found tossing a half inch ball bearing in the hole first solves this nicely.

    Love watching your videos, well done, you stay clearly out of the weeds, direct and to the point with very clear narration of each challenge, solution and errors. In my decades of machining it became very clear mistakes happen all the time, for you can't make them unless your working. It is the skilled machinist who can get past them oops mainlining quality results, you are very skilled. Cheers!

    My tail stock quill has always been extremely stiff, but I didn’t know if that was intentional. Instead of it sliding out as in the video, I had to knock it out with a hammer. After I cleaned it up, my quill now moves smoothly as well. Many thanks.

    Thanks for the inspiriation, Quinn, and for pointing me to Presso's version for us non-squares. Wanting to add one to my Myford ML7. Do you think there should be allowance for quill twist under pressure? My 80 year old tailstock might be a tad less tolerance-aware compared to yours and Presso's idea of a pin to locate the dial might allow for some pressure twist in the quill. Don't know if your DRO has enough flex built in or if you should allow for axial movement in the mount for when things get serious, especially when the quill is not extended much and the angle of twist is greatest. Maybe not an issue but hard to tell without being hands on.

  • @ellieprice3396
    @ellieprice3396 Месяц назад

    Thanks for showing the modification to your tailstock. There's a more compact way to accomplish the same purpose if you're willing to seriously modify a four inch digital caliper. Basically you remove exterior and interior jaws and attach the head of the caliper to the ram. Mount the caliper to the top of the tailstock and attach the movable head to the ram for a very compact depth gage for your tailstock.

  • @joshclark44
    @joshclark44 Месяц назад +2

    Sometimes I do wonder how they design and make the original castings for those parts. Presumably you could still do it at home, but it would be a rather large cast and to do it with cast iron instead of like aluminum would take a lot of heat. You would also need a much larger set of machines to machine it square and concentric with the spindle etc. It would be interesting to see if a RUclipsr has attempted to make one just for fun

    • @Blondihacks
      @Blondihacks  Месяц назад +4

      The closest to that would be the Gingery book series. He shows you how to build a machine shop from first principles. A couple of RUclipsrs have followed his books. His machines are aluminum though. Casting iron is very very serious business and you need special facilities and very serious safety gear. You need to know what you are doing and it is not for amateurs.

    I have a digital readout using an encoder contraption reading directly off the tailstock quill screw. It works well but is not backlash blind as opposed to using a scale. It is very compact though which is what I needed.

    Hello.
    Incredibly beautiful quality you make, which is pampered for every detail.
    But the way you mount your tallstock, couldn't it be mounted like this?
    I use your drawing time 4.42..
    Shaft (1) is screwed back to zero point. In housing (10), opposite no. 18, a 7 mm hole is drilled 4 mm from the inside edge, down through housing (10) into shaft (1).
    Shaft (1) is removed and an 8 mm thread is made in the 7 mm hole.
    In housing (10), the 7 mm hole is drilled up to 8 mm. The hole is filed up so that it becomes a U.
    Shaft (1) is mounted again. A shaft with an 8 mm thread at the bottom and a 6 mm thread at the top for the tallstock, screwed down into the shaft (1) and finally the four holes and threads in the housing (10). Then the tallstock is ready for assembly .
    I have great respect for what you do. so
    This post is not to criticize your work.
    Regards, Per Højlund

    hi quinn,had the same problem with that different ejectionpoints of my tools on the tailstock.I solved it by adding material at the end of the"too short" tools so i didnt limit my travel on the other tools.Just spot-welded material onto the ends.Not the most professional way but at the time it solved the issue.Your solution is of course the more pro version.And the idea of putting a dro on it is well worth to think about.

    Suggestion if you find that the current DRO stack-up seems to be too tall: you should be able to get rid of the plastic backing of the DRO (or maybe replace it with a 1/16" piece of plastic) as that is just a piece of plastic to keep everything from falling apart in normal operation. If you get rid of that plastic back and the aluminum block you should be able to drop the whole thing by about 1/2".

    Neat set up! I did a similar tailstock DRO install relatively inexpensive digital caliper. It was a pretty easy fit on my PM 1130V.

    Nice work Quinn. I would think about a cover (clear hinged plastic maybe or perhaps a drop on box) to protect the little screen and the buttons while you don't need the DRO function. Cheers
