well lube helps alot. plus i forgot to mention that when taping soft materials its best to turn the tap one full turn then reverse the tap about a half turn out so you remove some of the material off the threads of the tap. if you tap in one motion(all the way in without backing it out) it will also make the whole alittle bigger and the threads wont be as tight.
