Hi Everyone!
I’m really appreciative for the responses I’ve gotten here. I went to Harbor Freight today to buy a Ball Joint tool and looked at the casters they had there. I couldn’t get the ball joint on my car loose but building a dolly seems simple enough. The only logistical dilemma I’m having is that I want to set the speaker on the dolly while using the cones and the Herbies Titanium disks. My thought is to drill a 1/2 inch depression in the dolly with a bit the size of the disks so that nothing moves around. Anybody with a better idea or rather any idea at all, please clue me in. Again thanks!
