Good morning,

I have a question or two regarding the Oneshot molds. I picked up a box of them 
sized per their literature for my size wire (#4 bare, solid copper). It seems to 
me there is an awful lot of airspace between the metal sleeve that fits into the 
mold and the wire itself. Is this normal, expecting that the weld material will 
encapsulate the wire without too much leakage? For sticklers, the outside 
diameter of the wire is 0.205" and the inside diameter of the sleeve is 0.242". 
I am aware Cadweld lists a part designed to increase wire diameter but is this 
necessary? If so, couldn't I just wrap a small gage copper wire around the other 
wire thereby increasing its diameter?

Tnx es 73,
Jim W5QM
