oo late for some pics tonight.....I was aiming for the slide to be no wider than 110mm, i have 16mm rail on the same type bearings i used for the rest. the main problem is using 4mm ali sheet (bad idea). These imported bearings are spot on except the mounting holes. I was also trying to use the same type of rail supports i used for the Y. im thinking now finish it of in MDF and make the parts afterwards when i can get me hands on some more material. Does that sound more sensible???
