Need some advice.
Long story short, the idea was to bush the ends, drill out to 1/2" and ream to 33/64" (as per engine drawings) let down by a friend who said they had a long reamer that size (turned out to be a hss drill bit).
Don't have a photo of finished item, as it's back on the engine, but basically the bush holes are slightly oval - I think there's a slight ridge which is pushing the drill out of line.
Is there any way to use an adjustable reamer, so I can ream the bushes and the small ridge in the casting ? I can turn up a new shaft easily enough.
Last time I used an adjustable reamer (or any reamer come to that) was over 40 years ago and I'm well out of my depth with this - reaming, not enough time to strip and and remake bushes and mill out casting (due in steam by the weekend).
From a 4" scale miniature traction engine.
Will try and add a photo of one end, might explain things better.
