You can call me Sean, and no worries, the Lord has brought me this far, He won't let go

I'm just a few years older than your daughter.
There is a doctrine among Christians called pre-trib, those people who believe Jesus is coming back before a tribulation period. I tell people I am pre-pub. He has to come back before my girls hit puberty
Not trying to hijack your thread, I was just saying I have learned to "make things work"
It's great that you are investing time in your grandkids life! It is important, you pass things that their parents can't. I remember just walking around my grandpa's shop, I can still smell the shavings and pitch he used on the outside. I actually have some of his old tools.
Anyway, back to the topic at hand

Can't wait to see what you put together.
