    Handwheel Mod.

    One of the things that I always wished my Grizzly lathe had come with is a Handwheeel on the outside of the spindle. It is a real pain having to constantly reach for the wrench especially when I know I could unscrew what ever attachment I had on by hand if I had something to hold onto. I have searched all around and never found anything that would work. I did find a handwheel that would screw into the left hand threads for $70! The problem with this is that you lose the ability to use the knockout bar.

    I decided to design my own to fit my needs. My design called for a two piece unit as I want to be able to remount the side cover and I don’t really want to cut a big hole in it. So this is what I came up with today;



    The outside diameter of the handwheel is right at 4” it then steps down to 3” and the to 2”. I tapered all the sharp edges and knurled a band around the outside of the wheel to help with gripping it.



    I left quite a bit of metal on the spindle as I wanted the strength. The assembly slides onto the spindle 1-1/2” and is locked all together with 4 set screws. Once I got it mounted I find that it runs very true and I do like it.



    I left the exterior machined flat as I want to machine for a vacuum adapter later as well as a drawbar system. I had originally thought that I would turn a wheel to bolt over top of this out of wood at about 6” to 7” but when you look inside you see there is a lot of spindle hanging there with no support. Later if I decide to do something like that I will mount another bearing.

    Anyhow, one more thing done on the list of “I wish my lathe had”.

    Nice work again, Ken. It is easy to see that you are a pro at this as well. The finish looks top notch on this. I don't ever deal with the finish. If its the right size and shape, it works. I do want to learn to finish though.

    What type of knurler do you have? I bought a cast iron scissor type from Enco that is really too large for the 7 12. It was on sale. I could modify it to fit the tool post, but.......as it is....I don't have a knurler.
    If you only have the bump type and would like it, we could work out a deal maybe. [8D]
    Thanks for posting this. Nice design too, BTW.

      Lee, it depends on what I am going to use the piece for as to how much I worry about the finish cut. This piece is going to be touched all the time so I spent a little time on my final cuts. To make a final cut you need to have a nice slightly round nose bit and for most things HSS will produce a better cut. I do all of my rough cutting with indexable carbide because I am grinder lazy. For the final cut I switch to one of the 5/16” HSS tool that I have ground for either right or left. To make the finial cut you simply zero the tool against the piece and then set up for a .002 cut. I finish cut by hand as I cant get the power feed speed to agree with me for this type of cut, it is just too fast. To me it is kind of like dragging a bottom lure when the Bass are not biting. A very slow but constant turning of the reel.

      The Knurling tool I have came with my QCTP kit from HF. Item # 42806-3VGA. I bought this kit because I did not need to make any modifications to my machine to use it even though it is really made for the 7X10. It has 3 choices of Knurl but I choose the soft side knurl as I did not want cut my hand all up when using the handle.

      Today I finally get to use my mill! I love the Delta tool post holder that I bought and attached to my Grizzly but it is a tad to tall so I am going to fix that today!


      Also, as a side note did you ever get threading down? I remember at one time you said you were trying to learn to thread on the lathe. I am getting almost ready to cut some 18tpi on Ύ” rod and if you would like I could do one of my pictorials on my process if you are interested.

        That looks great Ken. I like using a handwheel on my lathe too. Now if I could just get one for my mini?

          Nice work! I really miss having a handwheel on my HF lathe. I'll have to find a solution for that one...
