Built the Sider body after shift. The P sensor was awesome to work with during the boring operations. The lathe's new control system worked very well and speed adjustment a breeze. The stock used was 2.5" CR. Cut to 3.250" and faced both ends for a overall length of 3.200". Stepped drilled to 1.125" and bored to ID of spindle. Secondary bore to OD of spindle X 1.875". A rotary was used to drill/tap and counter bore the spider. A small 1/4" re-ground end mill was used to set the depth of two stacked earth magnets for the Tachometer pick up. This measurement was 0.375 from the headstock end of spider. The four 5/16-24 set screws where at 90* increments (45* to magnet) and 0.750 from headstock end of spider. The other four 3/8-24 spider bolts are 0.5625 from end of spider to afford clearance once the cover is on.
Still need to modify the 3/8-24 cap screws with brass or bronze tips, but really needed to get the spider body mounted to have a working tachometer.
A long day after shift but had a blast with the new control system on the lathe.
And YES for those of you wondering, I cleaned up the mess, like it never happened. Haha!
