Here's a small set of book shelves I made to go under the unused breakfast nook of my kitchen island. Like my earlier cupboards (https://poal.co/s/Woodworking/567356), these are made almost entirely from reclaimed construction lumber. Raw materials used (dog for scale): https://pic8.co/d/301e2421-77f3-4062-9a41-02d6f41df819.jpg https://pic8.co/d/224c052d-2f04-4528-8a37-dbfc3d6283be.jpg Rough lumber was flattened and jointed on one or two sides with a hand plane (here, I'm using winding sticks to check for twist): https://pic8.co/d/84e38097-3929-446b-92a4-16dcaf0d4b0f.jpg https://pic8.co/d/24ce0297-d321-4f1f-9249-fdcb9a128c71.jpg https://pic8.co/d/3c8ec5f5-74f2-4098-bc95-6a965b72a038.jpg Lumber was then milled close to dimension on the table saw: https://pic8.co/d/39b91941-6b59-40c3-94f4-1282f64454c2.jpg Mortices were drilled and chiselled out: https://pic8.co/d/ca7f118a-dc7f-4c6d-8e9f-a80811f72328.jpg Then the tenons cut mostly on the table saw, cleaned up with chisels: https://pic8.co/d/492f8262-9a84-4611-8271-dfa070b4aa96.jpg https://pic8.co/d/cb5d14c7-fd0f-4483-9a4b-64050098da00.jpg The bottom stiles of the frames had a split tennon: https://pic8.co/d/4f59b926-8eb4-42a5-8044-ba6b42303705.jpg Slots were cut to fit the side panels. The outer side panels are Oregon, and the inner ones are 3mm (1/8") ply, which is the same width as the table saw blade: https://pic8.co/d/662932cc-db8b-487c-92c0-0519d310e24a.jpg While making the Oregon side panels, I fucked up and cut one angle cut on the wrong side. This piece was able to be saved by gluing a strip of wood into the kerf: https://pic8.co/d/a279efff-2fe1-46e7-8347-dcfebfd2b620.jpg https://pic8.co/d/a1934f3c-5615-4ad6-906f-aba3b4a493f7.jpg https://pic8.co/d/71945823-0de6-48f4-adae-8957743f1e76.jpg Side panels finished (roughly): https://pic8.co/d/afc7cbda-8b0e-451f-a3ed-4af7d10ba935.jpg The shelves were made from reclaimed floor boards. A large bevel was put on the underside of the front of the shelves: https://pic8.co/d/dc289f76-4f57-4acf-a3d4-86e2f0775070.jpg https://pic8.co/d/d6db848d-0329-4782-af56-f5256f4a4b60.jpg https://pic8.co/d/dbef7795-82c6-4ce4-9346-6e4428494e93.jpg The shelves join to the frames through sliding dovetails at the ends and a sliding bridal joint (?) in the middle. The tails were cut on my shitty ad hoc router table, they turned out a bit loose, so I ended up gluing a thin strip on the tails and planing it down until the fit was good: https://pic8.co/d/77827625-ac66-4e07-a7ca-18af85758d4f.jpg https://pic8.co/d/8ea104e2-38af-4065-afa0-59d8f0dd5f65.jpg https://pic8.co/d/59fd2ee5-04d3-4329-b9e0-9735c4fb7d65.jpg https://pic8.co/d/1ce6fe45-903d-4b3a-8e6d-b464ae5207a7.jpg Here's all the bits basically finished and ready for assembly: https://pic8.co/d/7e8f81aa-3c63-45f5-bb2e-727e36edd377.jpg Test fit without the panels: https://pic8.co/d/2c94c72a-70b8-4ca0-b9ab-f9bd3f9f5852.jpg The front joints of the frames were glued and also used wedged exposed tenons: https://pic8.co/d/67893b26-42d4-46af-8432-57ce0876da38.jpg The back part of the frames was not glued on, but was secured with wooden dowels. This effectively makes the shelves "flat pack" in that they can be assembled on site with minimal tools. Not particularly important for this set of shelves, but might be a strategy to use for a larger (3m wide) set of bookshelves that are on the TODO list. The locking dowels can be seen, at least for the top joints, here: https://pic8.co/d/15e652cf-ffa5-4f4b-b0a3-c9358c38836c.jpg
