And the two fingered money shot, bearing in mind this was a 130kg lump when I started

Will clock the journal below it and machine new section to suit.

Why wouldn’t they be tight? Straight is straight,is it not? It’s a question of knowing what is important and what isn’t. The bore has to be spot on, as does the height,as does the bolt positions and dowel positions. The rest is well, just a casting...

You seem to be very knowledgeable about lineboring.

If you can measure it, you can make it!
You seem to be having a laugh.
I'm just saying - you've made the part (and its very impressive) - but how will you ensure the fitted housing is aligned?
No need to be condescending

Bit difficult not to be,given some of your previous remarks...
...”but I guess the tolerances aren’t that tight”
Insert is machined to 0,02mm tolerance to fit into the casing that I have already machined. It locates into a premachined socket for want of a better word and uses existing dowelpins to align it. It will be finished machined in situ with the other half bolted to it,having clocked the bearing journal one journal down from the repair,as already mentioned in one of my previous posts.
Not getting into the lineboring debate. It’s a bit more complicated than lineboring a digger bucket in that there are three shafts whose sizes and relationship spatially would need to be maintained. Hence the repair being approached in the manner outlined.
