Hello. I was working on some plates for expansion last night but before I could do that, I had to use the hold-downs to set up the material. Every single hole was not just plugged but so packed they would not blow out. I had to remove the sub-plate to get at them to clean them out. It was nasty and of course several years of stagnate cooling fluid was just a delightful smell (not). I have the sub-plate back on but I probably need to face it off to ensure it’s flat. I have the vise off right now but will have it back on and aligned tonight. Please do not remove the material I have on there right now.
