Audio Rack Construction


Happy New Year All!

I'm planning a rack with three wood (maple) shelves using threaded rod as the supports. This will be something similar to Salamander racks. Besides, the metal washers and nuts, I'm going to be using some type of isolation washer that will contact the top and bottom of each shelf.
So...shelf, isoloation washer, metal washer, and then nut.

Questions: 1. When passing the threaded rod through each shelf, should the holes in the shelves not allow the threaded rod to touch, so the only thing touching the shelves are the isolation washers? 2. Besides neoprene, what's a good material for the isolation washers? 3. After leveling each shelf during assembly, I'm planning to add aluminum tubing over the threaded rod and nuts between each shelf for a cleaner look. This would mean that the top and bottom ends of the aluminum tubing would also contact the shelves. Should I avoid this, or additionally add some isolation material between the ends of the tubes and the shelves?

Markeetaux...you should do that! I didn't stain my shelves because I like the natural maple and I'm considering new speakers. If you look at my pic you'll see that the cabinet to the right is yet another finish! Well, I'm replacing that cabinet as well. Maybe in the end it will all be maple.
Nothing like a 3 point suspension such as Sistrum. Nothing like a proper mechanically grounded metal shelf that won't warp and will maintain consistency. Tom

If you like I'll send you a photo of my speaker stands
when they are complete. I expect they will be done early next week. Nice job Kenny.
Well Done, Kenny. On leveling the top shelf: There a school of thought that says that you don't want the nuts on your rack completely tight, and that some feeling of play is better. Can't remember where I heard this, but you might look around; I have mine that way. Whyn't you level the top shelf for your TT, and give a listen? I'd certainly be keen to hear your results on an a/b: tight v. loose rack. John
