Being an old (that is, consistent) "3+" degree proponent (not sorry I brought it up), I'd only add here that I had a wee bit of trouble getting a good reading (digital level & Square process) until I firmly pinched the square's blade to the disc,as pictured. Due to air humidity/quality issues when mounted, my paper is not solidly fastened (imagine a layer of cottage cheese between it and the disc), and unless the paper's not forced against the disc the reading can be off as much as a quarter of a degree (horrors!). (Eyeballing square-to-disc used to be imprecise as you can imagine, prior to this discovery.)mickyd wrote:My conical disc is also just shy of 3-1/2°. Wixey just resolved just how shy. Where this comes into play is obviosly setting the table angle. I use a square to set it perpendicular the actual angle. If however you setting the table based on an assumed angle of 4°, it would be wise to verify it.
[Yes, of course I should remover the paper, clean the disc, take all to an air-conditioned room and reinstall the paper. But I'd rather spend hours trying to figure out why it takes me five minutes to align the table.]
By the wayside, if I align the Square's blade more vertically precisely, the reading is 3.3 degrees.[ATTACH]8880[/ATTACH]
