Iwata neo is a good airbrush for the money I use one personally
A hand rasp with a flat side and a curved side with both fine and course teeth is one of my favorite shaping tools. It’s cheap, safe to use and very useful in my opinion
I second the bandsaw and the sander is handy too
a drill of some kind. Drill press is nice but I have been getting by with a cordless for since I started years ago
For a lure turner any bbq rotisserie works just build a stand. Honestly there is lots of options and if you want to build one ask for options and members here will give you ideas. This is only needed with epoxy clear coats like envirotex and D2T
there is UV clear and Dips like KBS too that don’t need turners but have other issues
depending on what style of lures he wants to build there is other handy things to have
Other than that if you’re boy needs advice on a lure build ask away myself and others on this forum are willing to help
