Hi OF, If I were using a shrinking disc all the time, I would definitely get Wray's disc. That's pretty nice of him to send the DVD for free. I'm just working on personal vehicles. Plus, I only have a 4-1/2" angle grinder and would need to buy a 7" or 9" version to safely use it. I'm hoping I can put a handle on my drill to stabilize it and give it a go with a 6-1/2" drain clean-out plate. If that's no good, I'll try altering the plate to fit my angle grinder. If that's still not good enough then Wray's disc is next. Take a look at these pics of the Regal hood. The way the creases are on the edges, I don't know if it'll work. The hood is closed in all pics.
On second thought, it looks like the hood is open on that first pic. It's gotta be. Don't recall it being THAT bad.
