Homemade Kung fu equipment

I live in an apartment and I can't really make noise but I need something to hit that I can focus on instead of just doing the motions in front of a mirror. I was thinking about cementing a pole (6 foot bo staff) into a paint bucket and attaching some pieces of wood to the side of it so that it doesn't fall over when I use it, but it could also be used to drill a wall bag onto. What are some things that you guys use to train and how did you make/where did you buy them?
