Hey Laurens, Yes - lubricate the rollers with grease - use silicone grease which has a high temperature limit and resists centrifugal force throwing it out. My experience is that a small amount of grease finds its way quickly to all parts but best to get it to the back if you can. The down side is the aluminium turns it all black and it is sticky! I don't think greasing one end will make torsion worse as the greased end will provide no resistance to any twisting at the other end. The tray is a good idea but cooling is important so the mesh would be the right choice.
