I need to find a resource or two regarding the instal of my solid boom vang. I'm uneasy drilling into the mast without a solid plan. Any advice on procedure or steps would be appreciated. I wouldn't take issue with even the most rudimentary advice.
Read all the instructions
Measure twice - at least

If you work alone use tape or lashings to keep the bracket in place while fitting.

Drill the first hole (at one corner) if you are going to uses screws tap the first hole and fix the bracket in place (if you use rivets just insert a rivet (w/o poping it) in the hole to get the bracket aligned)
Make sure the bracket is aligned.
Make the next hole diagonally at the opposite corner, tap and screw .

If you are using rivets I would fix it in the two corners before proceeding with the rest of the holes.

Drill the remaining holes, tap the remaining holes.
Use a compound (Duralac/teffgel) to isolate dissimilar metals when you do the final mounting.

That seem to be a bad depends of the cut on your sail.

From this
Hoist the mainsail, and sheet home hard whilst ensuring
that the Rodkicker does not ”bottom”.
Leave a little extra play when the boom is at its lowest position.
