first time using expandalble reamer on conrod bushings -

[john.k]

Ive never seen a berry hone that small ........and for the record,back in the day when vintage motorbikes were free for the taking (long time ago),I have used a combination of scraping and a brake cylinder hone to fit an oversize piston pin...........now ,its quite a while since all the major parts suppliers sold oversize piston pins for all popular cars,but true never the less......most cars went to pressfit pins around 1960 or so............as an apprentice ,I was also shown a method of using an old file ,and slips of hardwood to make a single size reamer for piston and pin bushing work.
