Set of racks

[bzr]

Northern Red Mahogany 200mm x 100mm. The lengths will be 2m long & weigh 26kgs/57lbs as well as some smaller c section shelves for a total of, 330kg/770lbs. Resonance will be assimilated ..... This is a very dense & Australian hardwood, jaysus have I got me some splinters already....

[Mike]

Nice! I was hoping this post was about another "rack".

Smart. High mass with dissipation. Isolates through mass and still absorbs component energy. Hard to perfect that combination better than natural hard woods. I got 450 pounds of solid walnut slabs 3.5 inches thick.

Wow, Australian's have very tidy garages.....

Just move in or did you clean up for us?

Looks like an interesting project. I've found dissipation to be more important than mass. You can achieve energy release without mass remembering that mass is a measure of an object's resistance to changing its state of motion when a force is applied.

Refer top photo, the dissipation is done through sorbothane pucks on the SGR Audio racks, work exceptionally well & the racks do indeed make a discernible change for the better to the sound. I want the timber as it's a hobby & also functional, thanks for the physics lesson though, from one kiwi to another! Mike, just for you....one more gander at Dolores

As I sad mass is for isolation; it dont move. Getting something to isolate and dissipate at the same time can be difficult. Granite for example don't move but reflects. Wood don't move but absorbs.

Finished product.

Mike.......Some racks are affordable, some are not.

Now, how long did it take you to see the shark?

[FlexibleAudio]

Is it me or are we lacking some symmetry there? The (her) left seems like he is trying to escape his confinement. That will probably hurt with resonance absorption.

[jdandy]

Kev.......Is that lumber going to build a rack large enough to display and support all your existing gear in your photo above?

[bzr]

I've been asked that before Dan, apparently it's the application, stay tuned

[bzr]

Now here's a lass that applies herself....

[Steve]

Kev...That's a heavy duty rack in the making, Aussie style!

AUSTRALIA has some unique timbers. Aussie reds have to be one of the toughest.

I also love the Tasmanian Tigerwoods...

[jdandy]

It seems to be the male condition. The word Rack conjures up a number of mental images. We like racks. So, just how many racks are there?

Audio rack




Record Rack




Female rack




Deer Rack




Roof rack




Car rack




Dish rack





Rib rack




Pool rack




Hat rack




Torture rack



Clothes rack




Tire rack




Female rack




Damn it, a duplication. Can't trust anyone. Well you get the picture. We are the rack loving gender. You won't get an apology from me.

[Steve]

^^^^ Lol

I like it Dan, Interesting how a man's mind goes right for that nursing instinct as a first choice when racks are mentioned.

Thanks Dan, the rack is coming along nicely in my spare time. Each length of timber gets a 9 step process:
1. Sand timber down with 40 grit belt sander rounding all sharp edges and diverts/holes as it is recycled timber.
2. Sand timber down with 80 grit belt sander with the grain & remove excess splintering.
3. Sand timber down with 120 grit orbital sander.
4. Apply danish oil liberally with paint brush & let dry.
5. Apply danish oil liberally with rag & lots of elbow grease too & left to dry.
6. Sand with 240 grit orbital sander & wipe down with rag dampened with danish oil to remove dust.
7. Apply bees wax with a rag evenly & leave to cure overnight.
8. Buff all finished timber with lambs wool buffer on orbital sander.
9. Take lots of photos of finished & assembled rack & post on this topic.

Do you do 5 yourself or have one of the racks in the photo do that job?

[bzr]

I just get left to dry!

[bzr]

Righto then.....

Looking good Kev. One suggestion: I would try moving the amps to the floor (on amp stands, perhaps with Stillpoints underneath the amps). Move everything on the shelves down a level. Rearrange a little. Remove the top two pieces of shelving. That should help with some soundstaging. You may find the height of the equipment rack causes too much diffusion. But if not, then rock on.

Looks good.

[jdandy]

Kev.......That rack turned out looking great.

Yeah I'm hearing ya. trouble is it's not my house so I can't put the tv on the wall. The choice of timber was the main reason for the rack, it is a seriously hard wood, so the amps are on stillpoints but stay on the wood. The tv is shocking for the soundstage but it is a lot better than before I started.

Thanks Dan, am pretty happy with the way it turned out.
