I'm sure many of you have had and have a rubi TS cutter. I've recently bought a second hand TS 40 of eBay and the handle shaft (the bit that moves up and down) where it connects to the metal runners on the 2 rails is loose and has a fair bit of play. For example it can move it left and right. My TS 60 has no play at all. Is this fixable does anyone know or have I been done over? Cheers
