The bushing worked out well draw-bar mod works like a charm too.
Havent had much time to run machine working on getting garage in order and now got caught up building a bench - rack with upper shelves that will accommodate bunch of bench machines . The key is have it all functional accessible . Work in progress stay tuned.
Other than that spent some time on Sunday checking machine spindle run out with a different tooling . The spindle has an error of .002 so everything thereafter was same or more. I ran trials changing tools in to see if any variation and repeatability. Using arbor only, collet, drill chuck cheepo drill chuck, keyless chuck After playing around cleaning fixing adjusting I was able to repeat to no less than .002 run out at tool spindle further down tool run out was slightly more. Up to .004 TIR ( 6 inches down from spindle ) I guess that's expected with this mill anyone have better luck?
Today only welded an 11/16 nut on the end of the draw bar . EZ access now and a breeze to do a tool changeover. After omitting the spindle nut that coverred the draw bar . Works great tightens loosens a heck allot better than that silly 9 mm square nut. Now I have 2 options wrench or small breaker style bar . Next is make an easier tool to use holing spindle . Nice to get back into the swing of things I did think of a few Ideas of tooling I will be adding/ making . The list gets bigger..... guess thats ok keeping mind occupied .
