Hey guys,
I was just at the hardware store to buy a bag of concrete and found this new product: http://usa.sika.com/en/residential/residential-home/product-type/post-fix.html. Well it is new to me anyways. What got me thinking here is using this material in steel tubbing to deaden vibration say for example in a router frame.
It is an expanding uraethane foam what I can see. You mix the two components together and poof a rapidly expanding foam that completely sets up in two hours. Obviously being a foam it won't solve a lack of mass problem but it might solve a vibration issue especially if that vibration comes from thin walled tubing.
They had a sample post sitting in a bucket, one thing that was obvious is that the foam was pretty hard. Harder than what you might get from insulating foam.
In any event I hope this hasn't been brought up before. It isn't often that I go to a hardware store and say "hey that is neat".
