Query: Well built, but...

Prior to ordering this product, I looked at many others. I even downloaded pictures to my computer and opened them side by side to compare them. Finally I decided on this pin vise as it appeared to be the best built of the bunch. And you know what, it is very well built. Not only for the price, but well built period! It has a "heft" to it that makes you feel the quality of the materials used. It works like a fine tool should.So, what is the BUT all about? You have to really crank down on the nut to get the collet to hold the bit firmly. Just using a wrench on the nut is not enough and there is no way to use a second wrench. You'll need to use pliers (I used small locking pliers). You want to be careful not to bung-up the knurls on the shaft when you do this. After the bit is tightened, the pin vise works like a champ.If the collets tightened by hand, or if there were an easier way to tighten the nut with wrenches, I would have given this product a glowing 5 stars.
