well last night I decided to put a length of rosin core solder in the stub shaft and heated it with a flame(bic lighter)and ruffed up the shaft and the stub prior to this attempt. when the shaft slid in the solder squirted out I let it cool and I could not pull it out so I guess it held. I also put a 1/8" shaft in the dremel and spun it down to 3mm only on the length that passed through the bearings so it now fits octura props&drive dogs.(just hope the solder holds) [sm=47_47.gif]
