The branding on the bearings is PDF, I tried searching for them but couldn't find them online, I got them off Chai before everyone switched to fred! not to sure about the rails, a bit bowed and terrible looking grinding bounce along the profiled angles but they seem smooth enough when moving by hand with a bit of pressure on them. time will tell I suppose.
I'm having a right mare trying to machine the faces flat for mounting the rails, it seems I needed a bigger mill because even with the gibstrips adjusted the bed sags with the weight when moving to the extremes of the slideways causing a bowed face so I'm going to clamp it upright and mill with an end mill instead of the flycutter I was using. what this means though is I am more than likely going to have to Epoxy my steel rails cause they are even longer and heavier than the aluminium gantry.
