This question is specific to a Wadkin PP 450, but im sure it has general appeal to all vintage cast iron sliders. This particular saw is missing the quadrant/crosscut fence. If it is anything like the Wadkin PK parts/accessories then there isnt a chance of finding such an accessory. However, im not necessarily attached to OEM parts. In fact, after using a modern felder crosscut extrusion with stops and a scale, i cant imagine wanting to lose all those features on a vintage saw. Has anyone personally fabricated a crosscut fence for their vintage saw? If so, do you have pictures documenting the design? It seems pretty simple to use incra/80/20 extrusion with off the shelf stops, but im concerned about mounting to the sliding table and squaring to the blade. I dont have one of these saws in my possession to think it through, and i also dont want to buy the saw without thinking through how to replace the crosscut fence. The old catch 22.
