I'm sure you have all seen or heard the quote, " It ain't the jeans that make your butt look big."
I would suggest that it ain't the saw that gives you crappy cuts, it's the blade. Your old CTD was probably a darn good saw. It may have needed the bearings replaced, I can not imagine much else going wrong with a CTD, they are designed for high production, in factory like settings.
If you truly want a great cutting saw, call Larry at CTD, he will set you up with absolutely the best blades you will have ever used. I just bought another set from him a few days ago, unbelievable, cuts through hardwood like butter, with out a doubt, the cleanest, best, cut I have ever gotten from a saw.
About a year ago, he sold me some blades for my metal saw, same story, I have yet to sharpen them, the bearings on the saw need replacing, I'm still getting perfect cuts.
A great set of blades will turn any saw into a fine, precision, cutting machine.
It has always baffled me why picture framers will spend thousands on a saw, then operate it with $60.00 blades. Not only that, they will actually brag about the cheap blades they are using.
