Can't find MDF (1 Viewer)

[Bob Bartlett]

I plan on building a tempest sonotube but I cannot find MDF. The local lumber and hardware stores sells something called sound deadening board, which they told me is used for speaker cabinet, but it is only 1/2" thick. Could I use this and glue two sheets together? If not what other kind of wood(that is relatively cheap)could I use for my endcaps?
Unfortunately the closet home depot or lowes is 2 1/2 hours away.

Well if it's a dense as MDF then laminate 3 layers together. If it's particle board don't use it. An other option is to use 3 layers of 3/4" plywood.

If I use plywood should I use the same thickness that I was going to use with the mdf or do I have to make thicker endcaps.

It depends which kind of plywood you are using. High grade cabinet plywoods (appleply, marine grade ply) are stronger and resonate less than MDF (so you could make thinner caps). However, those plywoods are $$$. Cheap plywood is a PITA and should be avoided (IMO).

One of the lumber yards had something called industrial strength particle board. Do you think that is usable? I can't afford the birch and apple ply stuff, the whole point on building this was to save money.

How far is it to the nearest Home Depot? They carry MDF in 1/2" and 3/4" thicknesses and will even cut it up for you. I know you live in the boonies of Maine, but there must be one within driving distance, right?

Thanks everyone for the help I finally found a building supply store that was willing to order it for me, they are about an hour away but I ordered a couple of sheets. Now I am trying to hunt down sonotube.

HI Bob!
No homedepot near by?
If you want to come by my home (Farmington) and Id be more than happy to help you make one. I even have 30" sonotube and multiple PVC pipe diameters for ports (no charge).
Let me know
