Milling 3. Fine adjustment an improvement.

Above pictures doing an improvement to the mini mill fine adjust of the Chinese mini mill . It always felt very sloppy and I found that very irritating. So far  I have removed the original block that carried the fine adjustment shaft and made a carrier block from aluminum twice the size. to give t extra support while the original cover will still fit. Next step will be making a bush for a bigger turning wheel left over from the lathe , which will make fine adjustment a bit easier. As can be seen on the pictures below . There used to be a scale on the original hand wheel this be came obsolete as a DRO has been fitted to the X Travel.

Spindle support  Sept 2019

 

I have great difficulty removing the collet chuck from the spindle hammering on the securing bold on top of the spindle can't do the bearings any good so I made a support between the collar of the spindle and the table and in this way make it easier to change spindle attachments.

Picture left and right . Support welded up and machined. as can be seen it has been placed in position to support the spindle bearing.
