Tool to remove piston pin?
 

is there a special tool to remove the gudgeon pin from the rod/piston? or do people just make their own?

Hello,
Yes there is a special tool for removing gudgeon pins but before we got ours I use an expanding wallbolt. It's a little fiddley but I did do about 10 engine builds before I had the correct tool.

where sells this tool? if not ill try that
