I started using a Scroll Saw 20 years ago and this is the third Scroll Saw that I have owned and I have to say that I am not overly impressed.My first complaint is the lack of a light, but I knew that when I purchased it. I was looking forward to being able to enjoy all the benefits that were advertised, quiet running, quick blade changes, and being able to raise the upper arm so that I would not have to keep bending blades to make internal cuts. Sadly I feel that they are not quite as advertised.Quiet Running.This is true, if your tension is set perfectly, and I mean perfectly, otherwise the machine as this very discordant CLANKING that it makes until you putz around with the tension settings.Raising the upper arm.You can, but there is no guarantee that it will stay up, I have not put more than 20 hours on it since it arrived (my shop is not heated and it is cold here in the winter) but I have already had to adjust the bolt that keeps the arm raised. The not fun part of this is that the blade, because it is not clamped in place below, has a tendency to slip out of the cradle that holds it while I am trying to thread it through a hole to make the next internal cut.Blade Changing.I already mentioned how the blade likes to fall out of its cradle which they appear to have attempted to remediate by adding a couple of pieces metal wire that do a better job of getting in my way when I am trying to put the blade holder in place than it does keeping it there. Also, good luck trying to quickly pop the blade holder in place without bending down and looking to see what you are doing. Finally, in my opinion, the blade holder that you need to clamp the blade into could have been better thought out. Because the holder is basically a threaded hollow, it bends the end of that blade as you tighten it which lowers the lifespan of the blade. If they had a solid surface that the blade would press up against instead of being bent into the holder, I feel that they would last longer.In conclusion, as someone who makes and sells a number of scrolled items, it is important to me to be able to both work quickly and accurately all while minimizing the cost of my tools or consumables. Maybe I just need to get used to using this machine, but so far it has both slowed me down and increased my costs by decreasing the life of my blades. I will continue to use it for a year, but if I do not start seeing better results I will be looking for my next machine.
