Let's brainstorm.

Then a center threaded bolt, which is threaded into the plate goes into the hole to push on the crankshaft. When this happens, the sprocket is drawn away from the crank. If there are indeed holes, you would have to make a special tool specifically designed to remove this thing.

Look at the new one- there are no holes.

But I like your idea. Take a 1/4" steel plate, four grade 8 bolts and the original center bolt (or a longer one the same pitch), and a handful of nuts and washers. Drill five holes in one 6" square piece of plate for the outer section of the puller, and make two strips with end holes to go behind the cog. If you can't get behind the cog, get a REAL 3/8" cutting wheel and cut slots in the sucker. Dremels are fine for little stuff, but real work needs full size tools.
