chop stick holders.


I just noticed that chop stick holders hold the chopsticks about 1/2 inch, or 1 cm, from the table.I thought they might make good cable risers. They're cheap and made of wood or bamboo.You will need quite a few, so low cost is important.I've never used cable risers and I'm a bit skeptical, but this is might be a cheap way to experiment rather than let my uninformed bias rule!

I like the design of the Grip-Rite rebar chairs more, and they're less than 1/20th the cost (per riser)!
I am having trouble silver soldering spade connector  on to the rebar

new proof of concept aka try storming single strand speaker cables....
I went to Home Depot today and bought a bag of the Grip-Rite rebar chairs, 20 of ’em for $3.60. Each has a 3" circular base, a 2.25" tall upright, on top of which is an open top half circle, plenty big enough for fat power cords and speaker cables, and any interconnect save the really wide flat type. Thanks @qilin_maker! I can recycle my toilet paper rolls now ;-) .
Instead of chopstick holders, tie three chopsticks together (like a tee-pee) and lay your cables in the middle. Bet you can buy a gross of chopsticks from a restaurant supply store for peanuts...
Great suggestion!  In a hobby filled with uber-expensive tweaks, you can go crazy for under $5.  Love it.
My Home Depot has the 2.25" tall Grip-Rite Plastic Rebar High Chairs in a 20-pk. for $3.60.

Its called proof of concept: Will elevating work? Elevate and see. That's exactly what I did. Only I didn't buy anything. Why, when books and cups and a hundred other things are just laying around the house?

Only after doing this enough times with enough different materials to prove the concept, only then did I buy a set of Cable Elevators. 

Then as it turns out the more resolving things get thanks to little improvements like elevating the easier it gets to hear other little improvements, like elevating interconnects, and power cords, and routing them in nice smooth arcs that stay away from other cables.

But one thing at a time. What did it sound like when you tried your first experiment like this?
If you’re a clever fellow or gal you can isolate the cable using some paper towel cylinders and some rubber band and pencils.

15 cents each.
Splurge, and use new toilet paper rolls that you remove the paper from. For greater height, paper towel rolls. For stability, maybe one end will slip into one of those rubber caps they make for the ends of ironing board feet/legs.
Hey, a solution that requires patience and commitment. And handwashing!  : )

How about the old toilet paper roll cylinders idea and put two notches on one end?

There's someone selling homemade cable elevators on here for $59.99 for 10 that seems very reasonable to me.
1/2“ is probably not going to be high enough off the floor to escape the static electrical field. How about the old toilet paper roll cylinders idea and put two notches on one end? Talk about cheap! 🤗
