    Smile Nutty Professor strikes again

    Hi Guy , am going to start adding my mad ideas and projects that i am working on here for my cnc machine , so here is the
    1st installment it my attempt at a 4th axis for my current and future machine , as I'm a bit of hoarder over the years and numerous projects started ( not Finished But the thought was there ) i have accumulated a fair ol selection of bits and bobs , so when the latest fad hit me , i had a brainstorm ( more like brain fade but we wont go there ) and thought of connecting one of my stepper motors to a 90 Degree reduction drive gearbox that i bought off ebay for my morion cockpit ( Shoulda gotten 2 LOL ) anyways by mounting this gearbox onto an 18mm MDF base plate and using my CNC router to make the motor mount i came up with This ( Voilą ) not original not new or groundbreaking but just done with bits gathering dust . i have attached the Drawing as a jpeg file for the time being but will add pictures and full PDF file very soon for anyone interested. not bad if i may say so , for a few hours ( i know it shows LOL Work .
