I went to Lowes which is right next door to the Target I bought the AT-TE.
I couldn't find any 3/16 tubing. Maybe everybody is buying it up for their AT-TE's?
You can buy tubing by the foot or a whole roll, somebody must have bought the whole 3/16 roll. So I bought some 5/16 tubing, one foot for 18 cents. I hope that works. Anybody using the 5/16? I know they mentioned it as either 3/16 or 5/16 in the fix article.
