Unal,
So you want to do it back about boot.
One way is to drill and ream it out to 4mm dia. and loctite it in. Try the fit first on some scrap brass first.
Another way is to drill it out to 3.9 mm dia then use a hand reamer until the shaft just starts to enter the hole. Then press it in.
What is important here it to use a hand reamer not a machine reamer, a hand reamer has a long taper to assist in keeping the reamer central and perpendicular to the hole axis. So your hole will have a slight taper.
Before you do this second method it is best to have a practice on similar material and size just to get the hang of how far the hand reamer needs to go in.
