Hi,

I'm trying to build something like this for sound impact isolation from my drums in my apartment:

Does anyone knows where can I get 3/4 inch thick wood planks that are at a minimum

5 ft by 6 ft

I went to Homedepot and their maximum dimension is 4 ft by 8 ft.

Lowe's website says the same thing.

Google is NOT helping.

Thank You in advance.

I'd make it out of two smaller pieces rather than one full sized. It will be cheaper and easier to find and work with.
Having said that, you can get MDF in 5'x10' sheets. It is used to make table tennis (ping pong) tables. Finding it locally may be difficult although I've run across it a few times. You could also look for a used ping pong table or ping pong converion top at a good price. New the run at least $100. You probably won't find plywood in oversize sheets. Here's one source for the MDF: 5x10 MDF.

Firstly, I knew you were going to be the one to reply. So Thank You for contributing with your building experience and coming to my aid!

Secondly,
"I'd make it out of two smaller pieces rather than one full sized. It will be cheaper and easier to fond and work with."
That's what the guys at Home Depot suggested but it seems to me that would beat the anti-vibration purpose, at least on the case they mentioned:

Use two planks with a beam on the center for support. If you do that the beams would transmit the vibration and totally defeat the platform's purpose.

I don't know if you looked at Gerdy's design but if you did and you still think it's doable using the two/multiple boards approach I have a question for you:

How would you hold the boards together by using only the foam for the "cuboids" and glue.


Totally separate from the boards issue. What glue would you recommend for this? Epoxy?

Thank You!!1

I looked his design and I've seen similar. A simpler approach is to use a hole saw and cut holes in pieces of wood. These holes contain the tennis balls and you don't need to cut them in half. The balls are much stronger that way and it is easier to build. The rubber mats are not needed but could be added if wanted. He doesn't say exactly where all the glue goes. The only thing he mentions is gluing the tennis balls. For most wood work and general building I use wood glue for wood, and construction adhesive for everything else. For this project I would use construction adhesive for all of it. You can join two pieces of wood with a sort of spline glued and screwed. It won't transmit any noise because it doesn't touch anything other than the wood it holds together. Here is a very simple drawing showing what I mean. You can add as many tennis balls as needed for strength and stability. Just an idea...
