I picked up a 10mm chucking reamer during the week and reamed the holes for the bearing pins. I turned up a piece of scrap so it was a slide fit in the existing holes and used this to line them up in my drill press. I picked up a small pair of v-blocks whilst I was in the US for use on my drill press and they have seen a lot of use since I returned.
Having not used a reamer before, I followed Russ' advice and halved the speed and doubled the feed (compared to a 10mm drill) and it worked a treat. The white stuff is a spray on cutting fluid.
When fitting the bearing into one of the carriers, I noticed It was really difficult to press the pin in. So I pressed it in without the bearing and I noticed that the slot in not perpendicular to the holes. I'm not sure how I messed this up
