Screws are great, and I have used them often. Having said that, consider this stuff http://www.evergreenscalemodels.com/Shapes.htm which I have used many, many times. The 1/16″ round rod (their item #222) is terrific, and available either online or at most hobby…   Read more»

Sorry I guess I should clarify me thinking. Im not sure screws will work all that well in quantum tubing.PML rivets. They work great. I’ve used them on very large rockets, too. They do work quite well in QT. That…   Read more»
