Hi NB,
Actually, I have seen a thread at Audiogon, and follow ups at AA about a rack made out of Ikea Lack tables. You use a Lack table per shelf, and cut the legs down to the size you want. The only issue was on the newer Lack tables, the legs are hollow, so you need to fill them in with something at the ends. After you fill in the ends, you put in shallow spikes in the ends, and then stack the tables. This gives spiked isolation between each shelf. You should use shallow spikes, because deep spikes dig in to the tops of the table. An alternative was to put a coin under the spike. I also saw where someone put a ring around the spike, to try to make the tables more stable.
This was originally offered at Audiogon as an alternative to the Flexirack, that would be just as cheap and easy, but would sound better. The author said the construction of the Lack tables was good for isolation of audio gear. I thought about building one, but my wife wants a rack that looks like ?furniture?, and this would not really fit her definition of furniture.
