    I’m rebuilding an early 90’s ENCO 9x20. Someone had stripped it and started a “CNC” debacle 😆. I’ve been watching all your tread mill motor vids and building my motor setup. Really helpful info here.

      It would cost additional money. Why should they bother adding it?
      As long as other mini lathes don’t offer it they will not lose in sales unfortunately.

      The way they set it up is "good enough" so they don't add it to save a $ and let the end user make a change if the end user so chooses. Interesting enough observation my PM 728 mill is of the highest quality in every aspect and I was extremely impressed with all the big mill features this bench top mill came with but the lathe is not quite as high quality as the mill. Don't get me wrong it's a nice lathe but by comparison to the mill there are lots of little areas where budget features like this were utilized. It is however quality where it matters in areas of accuracy.

      @dazecars good to know this. Really looking hard at a Grizzly lathe also but most videos I find in comparison point to the PM lathes, although the earlier models were made in Taiwan.

      Wouldn't have it any other way, as it was not my idea. The machining on yours was beautiful but a little more complicated then I wanted to deal with. The simple answer on why this lever is not installed from the factory is $. It would cost them more to manufacture and no end price value is added. In other words it would not allow them to raise the price of the machine to offset the costs.

    • @bruceang82
      @bruceang82 หลายเดือนก่อน

      @dazecars having watched your video, I can assure you my lever probably took less time to build & is quite simple really, my pin is very tight on the locating hole & I would be concerned with the looseness of unsupported 3/4" of the pin to hole aspect. As on most of my projects, I strive for a clean, functional & well-presented appearance. I put my builds out there for educational purposes & enjoy other people's take on the same problem (as I did with Joe Higgins) Cheers & have a nice day. 😄

    • @dazecars
      @dazecars  หลายเดือนก่อน +1

      I hope you didn’t think I was knocking what you did. It’s beautiful work and it is an excellent solution . It was just more machining than I wanted to tackle. The only thing I had, to machine was the diameter of the shaft and the knob. As far as time spent I was able to make mine in an afternoon. The mounting bracket/lever is over 3/8 of an inch thick, which is more than enough to completely support the shaft and keep everything tight and true. Again, I really appreciate your video and the idea for this lever that it provided.

    I'm the last person to be offering electrical advice but... when I bought my Myford lathe, the previous owner had added a toggle switch to run the motor in reverse. Just turn off the motor, flip the toggle switch, restart the motor and off it goes. In reverse. I have never investigated how this works or how it was done. It just works.

    • @dazecars
      @dazecars  หลายเดือนก่อน

      This lathe has forward and reverse at the motor. All I need to do is push a button and the motor changes direction but that does not help in this situation. The carriage has power feed in both the X and Y axis as well as feed for single point threading. This power feed is driven off the spindle so to change the direction of the power feed without reversing the direction of the spindle you need to move the direction plate. Simply changing the direction of the motor would change the direction of the power feed but it would also change the direction of the spindle.

  • @shawnlindemood6678
    @shawnlindemood6678 หลายเดือนก่อน

    This came out well. For my 9X20 I had to make the whole reverse plate and add a gear. I added adjustable end stops for my shifter (like others did) to fine tune the gear mesh. My gears smaller and a little more sensitive to where the detents went.

    One of my old lathes had this "built in", but interestingly my new Grizzly has f/n/r for both the carriage drive and the leadscrew in a gearbox. I am gonna have to ELS the thing, I really don't car for change gears!

    • @dazecars
      @dazecars  หลายเดือนก่อน

      I have all the parts to convert this machine to ELS but being that this lathe has a threading transmission there is not as much of a reason to change. I can do almost any imperial thread without changing the change gears. Simply turn a knob. At some point I will likely go ELS but its not a priority.

    It's funny that my PM1022 has a knob on the front panel for forward-neutral-reverse of the leadscrew. Not sure why they don't do that on the 1228. I like your lever idea better though.

    • @dazecars
      @dazecars  หลายเดือนก่อน +2

      First of all this is not a junk hobby lathe, second ELS is in fact a fantastic option even on smaller machines. For years I made a lot of parts using a Harbor Freight 3-in-1 mill lathe combo (many would consider that a "junk hobby lathe") It served me well however it was not setup from the factory to thread. I added ELS to it and that completely opened up what I could make on the machine. It was one of the better upgrades I did to that lathe and well worth the time and money.

    • @paulshermet535
      @paulshermet535 หลายเดือนก่อน

      I put ELS on a worn 50's 10" Atlas lathe. I had very few gears. Now, I can change feed rate on the fly, have no noise and don't waste a bunch of time with gears for threads or feed speeds because I don't have a gear box. A used one is $800. My Clough42 ELS, all in,(stepper, belts, encoder, toothed gears and electronics was half of that with almost limitless choices. Will never go back.

    • @dazecars
      @dazecars  หลายเดือนก่อน

      Agreed, I was very happy with my ELS on my old lathe. If I was messing with change gears I might be more motovated to upgrade the new machine.
