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!
