Ok, just to get this party started. I am one to want to be organized and was looking for a place to park my shocks when not mounted and or working on them I had a block of dense foam and found that my wifes apple corer (I used pampered chef type. Don't tell wife:D) was just the right diameter. I pressed the tool into the foam in a pattern with the front close together and the rear behind and wider so I would know what went where. Once the proper depth was cut I pinched out the core. It works for me.....

Pics?
