Hey, you don't need a shop...... I know a guy that builds his rifles in his bedroom & does an awesome job of it... Couse, I hear his wife gets a lil testy at 2am when he kicks on the drill press or belt sander.... But somehow he has managed to live thu it ! ha ha ha !
A Lyman or T/C "Assembly" kit you can do on the kitchen table with an exacto knife, screwdriver, sand paper & a few files.
If you mean a set of "Parts" to build a longrifle, here ya go.....
You need a good drill, set of drill bits, set of small Nickolson wood files & metal files, a large mill file, 2 or 3 8" or 10" wood rasps (one round & one halfround) a small bench with a vice (can be a fold up portable one), about 3 carving chisels (for intricate fits & inletting), a hammer, screw drivers, small set of punches, pliers, inletting black, sandpaper, a couple of "C" clamps in various sizes, about 2 doz #3 finish nails, Superglue (I like the medium & thick *Hobby Lobby*), Elmers or Tightbond wood glue, a coping saw, a 1/8" - 1/4" - 1/2" wood chisel, a 6" dial caliper (not a must but very handy) and a good rifle kit & you will be on your way. Depending on flint or percussion, you will need a tap & proper drill for the drumb/vent & a countersink bit or is percussion a drum drilling jig. Also making a drill point jig or buying one from Cain's Outdoors is a good idea & may save ya some drilling errors ya can't cover up. Also a 8-32 tap or/and 10-32 tap & appripriate drill bit. Get a set of "Plans" for the rifle to be built, and I sugges the book "Gunsmiths of Grenville County". Now there will be more tools that make things easier, but this is close to all ya need.
I suggest a Chambers Isaac Haines kit or a Dunlap Isaac Haines kit as I know the kits & they are excellent & the precarves are down close to where ya need to go & not much wood to take off. I also suggest you buy ALL of the parts from the same place as this way you KNOW the scokc is partially inlet for the parts you have. (Some stocks are paartially inlet for paarticular parts & use of others may leaves gaps & holes) Also I would insist on a Chambers built lock from his shop. (Lifetime warranty on parts) . Also, I know the wood from either Chambers or Dunlap's place will be excellent.
Good Luck !
