a good temporary fix for your hollow axles is to put solid round stock in your axle,the whole length,carefully weld the end so it does not interfere with bearing removel(NO BURRS!)or you can drill and tap the outer center hub to secure the new inner core shaft,whatever works best for u,then drill out your sprocket holes,oversize if needed half inch if needed some times
