A relative productive day today. As the original return rollers were not so good I modified some Bren carriers ones. Fortunately the centre hub is identical and also the bearings I just had to reshape them. Bren rollers have tapered sided and 12mm wider than the Vickers so I was able to machine the rubber off and reduce the hub 6mm either side. The overall dia is smaller as well, so with some patients I reduced the outside which intern gave me very good rubber.
I also put the engine and trans back in and made up some clevis's and rod for the clutch
which I might say works well. I just need to make 2 brake rods and the accelerator linkage and it will be ready for the final drives.
