    sprinter,

    Interesting project!

    Do you have a materials list, diagrams, etc. that you could share?

    Thanks.

    Sorry, not at this time.

    I changed the Headstock to the "593" Taig Headstock, this allows using .500 stock and use the cutoff tool to cut machined parts from the bar stock. It saves time and material when trying to chuck up and make repetitive parts. The more I use this lathe the more impressed I am.

    Hello Sprinter,

    I`ve recently got myself a taig (peatol here in the UK) I want to convert it to a CNC machine but keep the manual function. I`m interested in your latest design but could I just ask a couple of questions, bearing in mind I`m learning in engineering and not only that but this is my first fully CNC attempt (only moved single axis up to now)

    1. Could you possible send any more pictures of the X-axis (main carrage) traverse mechanism. I know you have posted a few pictures but I can`t see how the lead screw is supported at the rear end of the lathe. Also how is the lead screw engaged? I like the idea of keeping this on the back as it seems to keep it out of the way. I also guess if you can disengage this, full manual control will be gained.

    2. The frame you have used it 20/40 frame you said. I`ve done a search for UK suppliers and is this the stuff: 0-132-2020 Aluminium Structural Sections Profiles Retrofit Frame | World of CNC - Marchant Dice
    I presume it is about 400mm long as the bed of the lathe is this length, what width did you use - I have noticed from your pictures that actually the frame is quite wide.

    craynerd,

    This design is strictly CNC with no manual capabilities other than using Mach3 software in the lathe manual mode. The X axis screw is not supported other than on the stepper end. I'm using all the hardware from the Taig mill just as it is used on the Taig mill. I made a block that is bored to hold the Taig screw nut and the block is attached to the Z axis using the Z axis "T" slot.

    The 80/20 channel material is 1"x1"x16" for the front and back bar and 1"x2"x12.5" for the sides for a 16"x14.5" overall size You could probably use 1"x1"x12" and 1"x2"x12" to save on material costs.

    You may want to rethink trying to make your machine CNC and manual. Using a split nut design to disengage and engage the X axis screw will not give you the backlash tolerances you will need for the CNC.

    Do you have a cnc machine at this time or have you had one? The desire to be able to manually control a machine is every first time builders concern. Once you use a cnc machine at all you will see how unnecessary it is. You will be able to place the spindle/tool and or table anywhere you want it pretty effortlessly. You can use the keyboard/mpg or shuttle pro to control the machine while you watch very closely. Dont let the desire for manual controls get in your way.

    I ordered a Tachulator LittleMachineShop.com - Tachulator Tachometer & SFM Meter. It has some great features such as SFM as well as a tach. Does anyone have any experience with this device? As soon as I receive it and get it mounted, I'll add some photos.
