I am very new to the whole Festool world. I was convinced by some people I trust and took the plunge so to speak on a TS55. I live in a remote area so the only realistic way to buy tools like this is online, so I don't often get the benefit of testing before buying. My TS55 has arrived and I realize I made a mistake in ordering a FSK rail with it. I did a fair amount of research and was convinced that I saw a video saying that they were compatible and in hindsight I can only guess that I'm horibbly mistaken. I was really thrilled at the idea of having the ability to select very specific specific angles to cut, but alas and now I am wondering why the TS55 is incompatible with these tracks and there being no similar alternative. At least not in South Africa, despite there being quite a following here, but I'll admit I may have missed something. The FSK is brilliant and I just can't understand the logic here.
