Tim, The coincidences don't stop there. We both have '51's.

Unfortunately, my dad's been gone since '96, and I'm sure my mom couldn't find that tool if she could even get to the garage. If I happened to be down there, I'd be happy to dig it out and loan it to you. Even that might take an hour or two.

Mom's place is not far from you in Carpinteria. I've been thru Buellton a time or two.
Next time I'm down there, I'll have to look you up and we can compare notes.
I have used a suction cup on a stick before as well. It'll work, just not as cool as one of those old eggbeater valve lapping tools.
