Can I just say that I have owned a few machines in my “scroll saw career” to date, starting with a cheap one that only took pinned blades and was only single speed. I then moved onto a Delta two speed scroll saw that took pinnless blades and had a quick change feature for the blades. I then bought a variable speed Delta with the same quick change feature for the blades and would have kept that if the arm length was longer. I found that to be very good quality and very low vibration. I then bought an Axminster trade EX21, which I still own and would highly recommend it. I have it fitted to an Axminster stand and do not find any excessive vibration with it and particularly like the tilting head feature and the fact that you can feed the blade either from the top or the bottom on pierced work. In the meantime I was also offered a variable speed Hegner scroll saw with a stand at a good price, however shortly after buying it the variable speed packed up. Hegner wanted over £500 for a replacement motor and variable speed unit. Luckily an electrical engineer on this site repaired the unit for me. I gave the Hegner unit a fair trial for a while but still preferred the Axminster. The Hegner unit is of an old basic design compared to the Axminster and so doesn’t have the same features as the more modern units. So in summary, it’s up to the individual’s choice, both are good quality and well made, the Hegner is of an old but proven design, the Axminster more modern with well designed features. At the end of the day, you pays your money and make your choice.
