Change spark plugs and tubes?

Here's a tip for you on the tubes - use the mandrel from a 1" drum sander to pull them out.

I tried Pedro's suggestion of using a 1" boating transom plug, but I had trouble getting it tight enough to grip and by halfway through the job the transom plug was trashed. The drum sander mandrel fit better, has a bigger gripping surface, and is much easier to tighten up.
