Ignatius, with these acquisitions from your friend you’re starting to equip a workshop. I know that you’re anxious to buy more power tools but let me suggest a more budget friendly direction that will also improve your craftsmanship. Buy quality hand tools as your projects require them and learn how to use them. More power tools can come as you find good deals and as your budget increases.
You have bought a solid hull kit. I would not let that router get near the hull of this model. It can destroy it in an instant! Instead buy a quality small hand plane and a spokeshave. Both of these, especially the spokeshave are used to shape solid hull models. Chisels are used too and you apparently already have some. To sharpen, buy a sharpening guide and a sharpening stone (oil or water as you prefer). There are guides on line and several good books available about sharpening edged tools. DO NOT try to sharpen edged tools on that powered grinder! Like the router it is too aggressive.
The University of Michigan operates a 450 ft long “towing tank” for testing models of ship hull to determine resistance. As a student there in the 1960’s, I watched professional model makers sculpt highly accurate models to be towed in the tank from clear white pine. Although the laminations to build these models were sawed on a bandsaw, shaping was done by hand. I still have and use a set of three miniature spoke shaves bought back then for a student project.
Power tools have their uses building models but first develop skill with hand tools.
Roger.
