Sorry if I rubbed you the wrong way. I didn't mean to. It is just that I have read so may threads on the center support issue that I just don't understand what the big deal is about. I just bought a drill press 2 weeks ago after my 4th build. I was making my center supports using a hand drill. Just center punch it first and drill a hole with a # 21 drill if using 10-32 screws or a # 29 drill bit if using 8-32 screws. Drill about 3/8ths of an inch deep on both ends and tap it and your good to go. If you use solid rod it drills easy and then heat it with a map torch till dull cherry red, quench in motor oil and then heat to blue and let cool on its own. You can make about 20 of them from a 36 inch piece of unthreaded round rod bought at any hardware store for about 3 bucks. If your going to use rivets just buy a roll pin at the hardware for under a buck. Again, I apoligize if I came off the wrong way. ak'sr4me
