I own this woodshop. I have learned the equipment one selects is most important. Secondly, the equipment needs regular maintenance. I admit, I have not done my part in regularly maintaining my equipment. It is a painful learned lesson. For example, I purchased a power sander.... see that "BEAUT" below. It is a Supermax 19-38. That machine power sands wood pieces and saved me hundreds of hours of hand sanding time over the last couple of years. In the course of that time, the machine got out of "true" alignment and my wood pieces were getting sniped and gauge marks were appearing on the wood. I believed I had a faulty, no good, piece of garbage and was ready to ditch it. Before I went to that nuclear option, I called Laguna Tools and talked to the tech rep. He explained the sanding platen might not be level or the roller bars were not aligned correctly. He then explained how to correct the issue. After three weeks, several minor adjustments, and a few thrown wood pieces, the Supermax is back in original shape. Turns out the sanding platen was not level and the roller bars were not aligned correctly. The moral of the story.... DO REGULAR MAINTENANCE on your machines. If you don't know what to do, call the company and ask to speak to the expert tech rep. Then be patient ( I don't have a lot of this quality) and make the right adjustments. Now the machine is running like new and I don't have to fork out mega bucks to replace it.
