Having a problem with handcarves...

[Mokes]

I thought maybe you guys could help on this.

I want to try through-wiring handcarves so I can use these in the Canal. I'm not too sure the screw-eyes even though Devcon'd in, will hold up to a fish+current.

I marked my holes last night, drilled the belly hole out and drew a center-line along the back to follow and I missed completely.

I used the blank before I started sanding. I just had it cut out with the bandsaw and had my tapers cut.

Is there a smarter way to drill these, so the holes are at least CLOSE instead of me holding the blank in my hand and using a cordless?

My other question is, (if I can actually manage the through-drilling) when I drill out the belly hole, what is a good size bit for it, if I want to use hook hangers? Seems like the size I use for the grommets would be too narrow?
