If you find that your chips are not holding tight on the RBT 
jig pins it is time to change out pins. They do wear down over 
time - not only the pin nubs which hold the chips but they 
also get loose in the channel groove which can cause the chips 
to shift horizontally. You might even need to occasionally 
change out the jig itself if the channel groove gets too loose.

I have found a great deal of tolerance variance in the RBT 
mounts so try several mount/pin combinations to find one that 
is tight.

That's all for now,
