I forgot to mention, the hold-down bed, as is much of the machine itself, is aluminum. I was able to tilt the saw spindle to fit a sanding drum and work at shaving the top of the hold-down bed down, but the problem was, at that angle, I don't have any way to ensure the spindle housing gets locked into the mount solidly enough to do the shaving with any accuracy. It's what I did to get to the point where I started draw filing and scraping. The other issue is there's not really any way to mount an external tool on the cutting head to fly cut, or even mill. The flattening of the hold-down bed was one of those issues during the design phase that sorta slipped my mind. So, it looks like it's further development of my Popeye fore arms... ;-) Thanks, Mark ------------------------------------------------------------------------------ Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
