[QUOTE="SneakyCuttlefish, post: 399867, member: 3340"] A common problem is drum creep. Especially when the machine tilt is adjusted. Simple physics. The first idea was to make the collars a channel but the problem with this is it puts side loading on the bearings and will wear heavily on the up side edge of the roller. Easiest way to fix this is to add a fifth roller and a lip on the end of the drum. Barrel creep after just a few turns. Tilts is 20 degrees [img]https://www.prospectingaustralia.com/forum/img/member-images/3340/1521948663_20180325_110315_640x480.jpg[/img] Lip in place [img]https://www.prospectingaustralia.com/forum/img/member-images/3340/1521948974_20180325_115130_640x480.jpg[/img] Roughly were the fifth roller will be. Still need to build a section of the frame to hold it in place. [img]https://www.prospectingaustralia.com/forum/img/member-images/3340/1521948996_20180325_115157_640x480.jpg[/img] [/QUOTE]
