I have some adjustable ball links that are for balls that are 3.8mm in size and I would like to bring them up to the 4. mm Esky size (aprox). Has anyone a source for a ball link sizing tool that can bring them up to this size. I have a JR sizing tool but it is for Trex links that are about 4.7 mm.
I checked with several vendors and all they have is the the tool for Trex ball links and a tool for the for the 3.5 ball links but nothing for the Esky/Eflite size links.

don't know where to get the tool but....3.8 to 4 is not too far....if you got metal balls you could always do the old needle nose plier squeeze on them to loosen them up (light squeeze with the link on the ball). I know that is not the solution you want but it does work a treat.....I used that often on my old Walkera...I bought a copy head with balls too big for stock link (same diff I think) and thats how I got the links to work on it...they lasted just as long.

Also have heard it said that marring a sacrificial metal ball lightly with plier teeth .. then inserting in the link and rotating around a bit (slow drill?) worked much better then any ball resizing tool. Never tried it myself.

Thanks Tommy that second one sounds the best. Hitting myself on the head for not thinking of that.
I did try the first one using the taper of the pliers however it ruined the curvature of the link inside.
