Two things which I took to instantly and now wouldn’t want to do without are an old-fashioned two foot, four fold ruler which gets used all the time (there’s nothing that comes close to it) and a 1 1/2″ butt chisel which gets used all the time for marking anything which needs to be chopped e.g. the side of a mortice. It also means fewer chops and therefore a bit more accuracy when cutting out a knife wall.
The fourth most important basic handheld power tool every beginner should buy is a random orbital sander. While palm sanders are less expensive and can use plain sandpaper (cut into one-fourth sections), the random orbital version uses hook-and-loop fastened sanding disks, and doesn't sand in patterns, using a random sanding motion instead. This motion will serve to reduce the chance that any sanding marks may appear on the stock due to the sanding. Of course, be certain that your local woodworking supplier has sanding disks readily available in a number of grits to fit the model that you choose, as the key to proper sanding is to use progressively finer grits as you sand to reduce or remove any marks that are left behind from the previous sanding.
All reps were extremely helpful throughout the process of figuring out what to order. When problems developed due to mistakes by my installer not connected to Woodworker Express, the reps sent replacement hinges without charge. Jason, particularly went the extra mile and more helping me figure out what the problems were and how to solve them, even though the problems were not related to or caused by Woodworker Express..
Like you, I too am benchless. I built the “Mozilla” Molson vice variant from last year’s issue (I forget which) and it comes in handy for a lot of operations. I clamp it down to a piece of plywood that I have covered with formica (actually, it’s two pieces that I have piano-hinged together for easier storage) laid across two sawhorses. As long as lateral thrust is not involved, this is a pretty stable way to work. I also have a Zyliss vise for working on smaller pieces. I’ve made do for nearly forty years with a radial arm saw and circular saw. I have only recently acquired a planer and router table (both on wheels) It makes the garage croweded because also sharing the space are two motorcycles and about 400 board feet of rough sawn Camphor. I currently attend classes in woodworking and this coming semester I’ll be enrolled in a class for handtools only (and sharpening).

now I finally know what to recommend my friends when I try to convince them to give handtools a try (I currently am doing an apprenticeship in cabinetmaking (unfortunately mostly particle board) and said friends they do the same and often have no clue what can be achieved with handtools alone) because up until now, I never knew what to recommend for sharpening as my setup is great but very expensive. And I guess if I recommend to get two stones instead of a combination stone, one can keep one side flat for flattening the backs of new chisels, and add a strop with some polishing compound I really can’t think of anything else one would need for a long time!
