Looks like a good sander, is it an orbital sander? I have one that looks just like it. Btw, the project is coming along nicely!

What exactly does expanding foam do? is it for sound deadening purposes?

 

[crazy4ozs]

ya, for sound deadening...it mostly just stops ratteling...here is a good explination of what the differences would be between using raamat/fatmat and expanding foam:

Fatmat and Rammat deaden by "mass loading" (adding weight to something) That weight alone is what you're using to lower the resonance of the panel. eg., a 1 oz piece of sheetmetal may buzz, whereas a 4 oz piece of sheetmetal the same size may not make a sound.

Remove and tap on the sidepanel on your computer case.

Tape a magazine to it

Now tap on it again - Notice the sound difference?

Great Stuff doesn't weigh a whole bunch, but if you can use it to add some pressure to the panel, the resistance will in fact deaden the natural resonance of the panel.

Like the magazine test above; Instead of using a magazine (fatmat), imagine pressing a big sponge to the other side of the panel. The sponge isn't gonna do much by itself, but with that pressure (since the foam expands) it works - even better, in some applications.
