just got my new (used) vtrack easel today. upon inspection, the blades are kind of tough to move. Its not like I struggle with it, but I just expected them to glide pretty freely and I can see this as being a problem when I'm trying to get the borders just perfect for prints that I won't be mounting. Is this normal? I've never used a vtrack before, just the older universal ones with the knobs that let you adjust in very tiny increments. do I have to oil them or something? The easel is in great shape, I think its less than a couple years old. Otherwise it is really heavy duty and I like how the easel stays open without having to prop it up with any kind of latch or anything. Just waiting for my paper from freestyle and I can start printing again!
