I forgot I played with this today as well! I have to redrill the top hole as it's not lifting up more then a inch. All my other cat 0 toys have the full range of lift. It didn't go as deep as I was hoping but it did a good job.
I had lots of fun using the cat 0 for the first time. Uncle Gene didn't have any attachments for it so the first honor was all mine.
I got this from DWayne last fall. He made it for the BRS.
