No braces.....the plate is 3/4" Aluminum that weighs 60lbs. It was originally to be used for the top plate until David alerted me to change to Steel. Perhaps cross braces would be appropriate for thinner shelf material. I plan to brush or spray some enamel on the white casters to match the main stand's satin black powder coat.
so it will rest on the frame, and not be attached?

I'm not sure if it's bolted from underneath or not. I plan to support the motor control unit and maybe another phono stage. Perhaps a TS 150 will fit on it. ;)
a pair of TS-150's would fit side by side, since you have so much depth.

if the shelf is not securely attached I would expect it to resonate. and you may want some sort of interface between the shelf and the support beams that will compress to dampen resonance with countersunk flat tapered screws and bolts below.

or conversely; it might be better to de-couple the shelf from the rack and use some sort of damper interface.

in any case, just laying it on the supports is not a good idea.

it would be important to make sure that drilling holes in the support beams does not compromise the Nano-damping aspect of the rack (likely not, but good to check first).

I know I'm over-thinking this, but this whole tt direction is like that.

Since this thread deals with air bearing turntables I will ask for help here. My air bearing turntable uses this type of valves and pneumatic fittings and I am needing a few of each of them. Does any one know what are the correct designations of them, and it would be even better, a supplier in Europe? An eBay seller would be great! The ruler scale is mm, although threads are imperial.

I will ask them about it. At the very least, there would be a layer of damping material between the frame and the shelf plate.

Damping layer adhered to the frame, under the shelf plate has been confirmed. The 60lb shelf's weight is enough for a secure, vibration damped bond with frame. No bolts into frame were deemed necessary.

steel top plate 108lbs
2 - AVI Isolation Modules 56lbs
AVI Controller 8lbs
Frame 104lbs.
Total: 276lbs.
Dear Christian, the steel top plate looks natural (and great!). Did you decide to go with the stainless steel top plate? Or is this the carbon steel top plate which has been coated in some way?

(I am still trying to decide if I want three identical stands or if I want to copy your stand for the turntable. I remain flummoxed about whether to get an isolation platform for the turntable (your AVI or a TS-300 with heavy springs) but I am resolved to get a TS-140 for the Io control unit -- unless Mike loves the Taiko!)

I went Carbon steel that was blanched and satin clear powder coated. I avoided Stainless based on David’s recommendation. The table arrives on Monday FedEx freight. 380lbs. Total shipping weight including wooden crating/skid

bottom shelf is aluminum? as I recall, it's the leftover top piece from earlier.

the only caution would be to check periodically for any shelf warps, as that would compromise the consistent snugness of the interface from shelf to damping layer and likely cause resonance. large flat pieces of aluminum can warp over time (or rather them being 100% flat to begin with are remote). worst case you would need to screw it down in the future at some point. more just an awareness of the potential issue is necessary.

Good points. Yes...the aluminum plate used was to minimize the mistake of having it cut for the top plate originally.

Kedar,

It's a chunk of steel bloc. How do you see it beautiful :confused:. Wonder what your girlfriend looks like.

Love you man.

She squats and deadlifts more than my body weight, so yes she has some steel. I also see steel in her glare sometime when I am with her and exchanging texts with gian or Ron on the side

Very nice, Christian! This looks like good planning!
