DIY IKEA Lack Rack - Preparing the legs?


We are pulling together the parts to build my daughter her first audio rack on the cheap. Another post here about wooden racks brought to my attention some of you who have built racks from IKEA Lack tables, and I became very interested. I already have experience assembling an IKEA wall cabinet for my vinyl, so know that their composite materials are quite strong.

For the rack, you stack the tables up after cutting the legs to size that become your shelves. I want to spike the bottom of the legs, so that they stack up that way. The issue, is the core of the legs are hollow with inside dimensions of 1.75" x 1.75." Dimensional lumber like a 2"x 2" is only 1.5." My idea was using stock square lengths of turning wood that you can get 1.75" x 1.75.

Should I fill the entire length of the legs with the wood, or just insert a shorter piece into the bottom of the legs for the spikes? One of the benefits that's been said about the IKEA composite materials is low resonance even though it's strong. So, will adding a full length of wood to the core of the legs affect the resonance properties? I can go either way.

B,

From the pictures I've seen, just the bottom of the legs have fiberboard. Si if you cut them open they're hollow. Here's a link:

B, Yup, that's what I have to do. So, if these legs were once filled with fiberboard, and now they're just fiberboard end caps, what's best to fill-in the legs with for resonance? So, that's the question.

Gotcha.
If I were to undertake this project, I would try to find some wood with as close to the dimensions as possible. Fill the voids with some acrylic 2 part epoxy-It should come in a caulking tube that mixes as it gets pushed out.
Let it set up.
Drill out the holes for the T-nuts and put in some glue or more epoxy into the T-nut hole before installing.
Then get some spikes from Herbies.
I would also use some Herbies Fat Dots under the components or any other isolation product (Stillpoint, Synergistic, etc).
Are you sure you want to go with Lack? I use Besta for my components.
