    Finished up the restoration of my Dawn 5SP Vise. Got the paint colour completely wrong but otherwise the new soft jaws and the jaw alignment works great. I made a transfer punch from a 5/16 UNC bolt to mark the position of the tapped holes on the back of the new Aluminium soft jaws. It has a 4mm hex milled to fit a 4mm socket that fits down a blind 5/16 tapped hole. A hexagon ER32 collet holder held the bolt in the 3 Jaw chuck on the lathe and for milling the flats.

    I have purchased a Hercus No.1 Tool and Cutter Grinder from a bloke in Wodonga Victoria. Getting it back to Adelaide was a logistical challenge 900km away. Was driving through Albury/Wodonga on route to Melbourne and saw it on Facebook Market Place and went to have a look. Hired a trailer in Melbourne, loaded up 350kg machine in Wodonga and set sail for Adelaide via Echuca. So 2100km later I returned the trailer. Two days later we had a leisurely drive back home to Adelaide again. The video below is just a first inspection and there is a few accessories missing. No Tail Stock, magnetic base, tools or grinding wheel selection. Needs a good clean up and restoration. Please comment if you are familiar with similar machines.

    My Mill Angle Plates now have a keyway milled in the bases to align with my mill bed.



    An Adaptive Clearing Tool Path was generated in Fusion 360 with a helical ramp down into the keyway pocket. The pocket was then contour finished to 15.875mm or 5/8" to match my Tee Slots.

    I use my Knee in conjunction with my Z-axis controlled Quill to set depth of cuts. Always too conservative but tool paths can be tested to try to avert disasters.

    Been thinking that ABOM79 could stack up 12 8x8x1/2" plates in his G&E Shaper and make 2 Cubes, TIG weld, face them, split them, slot them and end up with 4 angle plates. I would like to watch that. Would you? The paint will dry eventually.

    My mill angle plates can be used as a Headstock and Tailstock. Or just some heavy bookends.
