Picked up the scroll saw and stand few weeks ago. Due to a shipping snafu, the saw came before the stand. Set up the saw on my heavy oak kitchen table, made the adjustments suggested in the manual and gave it a go. It ran quiet with no vibrations at about half speed. When I turned up past that, it started rocking and rolling. Had I tried the nickle test, it would have made change...LOL. I was a bit disappointed. Almost ready to send it back, the stand came in. Assembled the stand, mounted the saw on the stand and tried it again. Voila! it ran smooth and quiet through all speeds. I love the ease on changing blades and the tilting head as opposed of the table tilt. The big test was how it cut! Made a couple of segmented pieces as well as a puzzle, cut like a dream. When I can split a pencil line with the blade I know I have a good saw. The saw came with three lower blade holders which made it great to switch blades when they became dull. The test will be how long it runs without any issues. I had my old Porter Cable for quiet a few years with no problems.
