I was going to suggest 'stop drilling'. I'd pull the tyre and tube and tape off and see if the cracks are present on the inside of the rim...It might be worth "stop-drilling" a small (say 2mm) hole at the end of the each stress crack. This helps prevent the cracks from growing longer and longer because the stress is spread out over a much larger area. It's a technique widely used in the repair of aluminium boat hulls and plane skins. It won't fix the problem but it should buy you some time.

Presumably all on drive side spokes?The rim is too far gone. There's at least 21 cracks found.

As a 'clydesdale' (fat bloke) it is ALWAYS driveside spokes that crack the rims on my mtbs.The thoroughness of my inspections has not stretched to that degree of accuracy as yet.
Two cracks per nipple. Do keep up.But probably sufficient to notice that the wheel doesn't have 42 or more spokes.
Andy is sitting in a hotel watching The Vuelta I expect...he posted on that thread on Wednesday morning. 'i Love Beds'It's gone very quiet.
Me too ! It's so obvious ... once you see it !I'm going to steal that idea
