I've built several cat trees and scratchers for our cats over the years, but despite my best efforts, they're always undersized for dusty.
So I put this together yesterday with crap I had in the garage. Honestly, given it was ~3 hours of work, I'm very very pleased with it.
The post has four screws through the base and two L-brackets. The carpet is attached with teeny 1" nails and was a pain in the ASS to attach to the circular base.
I'm most proud of the rope attachment points. I drilled a hole just big enough for the rope to pass through, then put a big brass wood screw next to it in the hole and drove it in. So the thinking is that, to restring it, it'll just be removing two screws.
Nice job with the rope. I always avoided restringing these things because I was afraid to use adhesive or a nail gun (those nails are very small and could get eaten)
