| Buy some MDF wood and cut into shelves that your components can sit on. Then drill 4 holes, one in each corner. Then buy 4 threaded steel rods and bolts and washers. Then put it together, this will make a very sturdy rack. I found it generally to be better than most inexpensive racks. |

| It's a rack for your CD, record player etc. |
| |
| It is better than most other inexpensive racks. It tightened up the sound and made it more defined. |

Four
legs would work fine, but I built mine with three - much
easier to level. A great project, performance for price
is just about unbeatable. |

I
did this also. However, I purchased enough mdf for nine
sheets of 24" x 24" x 1/2" inches. I
needed three shelves so I glued and clamped three sheets
together times 3. This provided me three shelves of
24x24x1.5 inches. Perhaps a bit more inert. Routed off
the sharp edges, sanded, primed, and then painted. Added
some nice casters that screw into the bottom of the
5/8" threaded bar. Spikes might have been better
than the casters, but this rack weighs about 130 pounds
empty. Fully loaded with three components the fully
loaded rack weighs about 330 pounds. So mobility is a
bit of a necessity.
Costs: casters: $80, all else: $50, Total $130.
Looks better than some professonally built racks I've
seen and would appear to function better as well.
Still the ultimate enhancement to this rack would be to
use maple butcher blocks 24x24x1.75 or thicker. |

The
ultimate enhancement to this rack would be to use
1" marble slabs polished on the top surface. This
adds not only weight and stability, but a surface that
is more cone/spiked feet resistant. |

Remember
that most good speaker cabinets are made out of MDF for
its ability to dampen sound waves. In other words it
will absorb and not reflect like marble or maintain a
stable resonate frequency. They make a 1-1/8" MDF,
I just checked the NET you can get 2" and 4"
thick MDF material this should work better than gluing
the 1/2" together. The glue makes the MDF ridged
and less able to absorb sound also it is more
susceptible to developing and retaining a resonate
frequency.
Bolts loosen over time. If you have the capability
biscuit joint or dado your shelves in place. Spikes
would be the best way to go for the bottom.
The finish well that is a tough one Latex needs ample
drying time before you place something on it. Enamel Has
a hard finish and is reflective. Lacquer is also
reflective but not as hard as enamel. I also would not
recommend laminate as it is highly reflective and will
have a resonate frequency. "I am thinking" Ok
by finishing the MDF the resonate frequency will be
changed and will also be more likely to retain a
resonate frequency instead of absorbing it. Latex stays
elastic there for there will be a lower resonate
frequency and the least likely to retain a resonate
frequency, it is still probably the best choice.
The resonate frequency will affect both Turntables and
CD units as everyone knows.
The last piece of this equation is a back. A back will
create stiffness of the overall cabinet providing a more
stable platform for front ends.
Remember to take the system as a whole. |
