"Well,one could(if they have the tools) either mill or grind a slot on the surface of the bearing for the rod to sit,set it in with at least "one" screw to hold in place then silver braze it.Basically filling in the slot with silver solder…"

"just an idea I had about small ball sizes was to solder to the side of the ball but it would limit twisting action"

"Yeah,I have a very "crude" and simple" sketch.All the stuff I drew up over the weekend is in the recycle bin.If you wanted to braze to the ball,wouldn't you just need to  orient the ball(after you braze it in with a rod) to…"

"I have been thinking for a 3/32 ball joint the rod can be soldered to the side of the ball instead of drilling a hole in the ball. Got pictures of what your trying to do? "

John Polacchi replied to Danny Samuels's discussion Is Flexible Urethane Foam an Option?
"Nick,wouldn't that also depend on how dense the foam is and if you are just using it to fill in "large" body parts(like thighs or the upper torso) and to help reduce the overall weight of the puppet?"

"I use stay brite solder for the 1/8 ball joints as the melting point is low I hold the 1/16 rod in a vise and put the ball on top with the flux and solder in the hole then I put some metal stock on the ball and heat it up with a propane torch and…"

Silver Brazing "small" balls to rods

Here's another subject I know has come up in the past,or at least I know that "silver brazing" is no stranger to subject matter.This is one skill I have yet to really master. I find myself needing to braze very small ball bearings to very small diameter rods.As small as .0625 to .125 with rod ends ranging from .03125/.040 to .0625 and the metric equivalents.Pretty much anything larger than .125 is a "normal" ball joint in my mind. I find it somewhat intimidating,not just because I have never…See More
