One step forward ten back.

Brutus, might be a pain in the arse mate, but I think you are doing things the right way. Always good to check, double check & check again once more for luck.
I also agree with the direction on clearancing the walls & not the rod bolts. Very easy to cause stress riser, when grinding items such as bolts. I know it can be done carefully, graining & then polishing. But on the plus side, if you ever want to change rod bolts, its a direct swap.
As you always say, better to do it right once...
Cheers,

Not as easy as it seems Bob , thought i'd have it sorted in no time...............
Layed the crank in , placed a rod cap & bearing on the rod journal with rod bolt , spun crank & cap then started clearancing the bottom of bore where it hits ,

then thought to meself the rod bolt did'nt foul this much with the rod & piston in the bore , so would be takin too much off

...........
Gotta be done with the piston & rod in the bore or too much will be taken off , problem bein the block has to be cleaned every time you drop the crank , pistons & rods in................that ole die grinder spits iron dust EVERYWHERE , doin one @ a time is a nightmare.
Good job it's only a baby 4.625 stroke , must be a pig with a 4.75 stroke.

There's not a great deal to come off , maybe .060 thou , leaving around .050 clearance , block has already been clearanced for the last set of rods , but the K1s have the rod bolts slightly over to one side , plus the fact the cap sits slightly higher , gotts have a steady/firm hand , don't want the carbide bit throwing itself up the cylinder wall.
2 down 6 to go.
