Table Legs & Terrific Technique

IMG_1883The LVL desk build continued with the legs. I milled 8/4 material, then joined two pieces to form four 3-1/2″-square legs. Square wouldn’t do, so we decided to taper the 28″ lengths over 24-1/2″, leaving a bit of square at the top. Tapering legs is best done at a jointer, if you ask me. As long as you hit your layout lines, you can nail each leg so that they are all tapered exactly. It took only minutes to taper all 16 sides.

Still, the legs didn’t have the right look, so we decided to chamfer the corners. But how do you stop the chamfer at the perfect location? You don’t. We trimmed the corners along the legs entire length; that left the square portion at the top end tapering out of the cut made at the router table.

IMG_1885To join the legs to the top, we went with a simple idea – dowels. If we would thought of this at the beginning, we could have drilled the leg ends while the blanks were still square. But, of course, we didn’t, so the set-up was a bit more involved. I rotated the table on my drill press, clamped a straightedge in position then centered the 1-1/4″-diameter bit in the leg, which was clamped to the straightedge. (Told you it was more involved.) Holes were drilled about 1-1/2″ deep because the arm of the press came down onto the rotated table to stop the cut. That wasn’t enough of a hole in my opinion. Afterward, each hole was set another 1-1/2″ in depth, and dowels were glued in.

For each leg to fit tight and flush with the bottom surface of the tabletop, it was imperative that the 1-1/4″-diameter holes drilled through the top be square to the large flat surface. IMG_1892There’s no better tool than a router for this work. I don’t, however, have a router bit that diameter, so there was no way to plunge the holes as you would when knocking out adjustable shelf pins. The next idea worked perfectly. drill through the top in the correct location using a smaller diameter drill bit (in this case I used 3/4″), then enlarge the hole using a top-mount pattern bit. All that’s needed is a scrap piece of plywood with a hole drilled exactly to size; that’s easy with the drill bit already in the press.

IMG_1891To use the jig, clamp the plywood piece in position on the table’s top over the previously drilled hole, slip the router setup into the hole with the bit’s bearing riding along the plywood cutout and rout a perfect matching-size hole in the top. To get through the entire 2″ of top, we had to remove the plywood and repeat the steps using the trimmed portion of the hole as a guide. Easy, peasy!

IMG_1897With the holes drilled and the dowels sawn for wedges, we slipped the legs into the top, spilled a little glue into the sliced dowel then drove walnut wedges to bring everything tight. The final look with the dowels and wedges trimmed look good. Plus, there’s no wobble in the table, especially after the glue dried.

LVL Desk in a Weekend

Steve's deskIt’s a holiday weekend. Yeah. I have an extra day in the shop on Monday that I intend to fill building a quick desk with my younger brother. He’s looking for something a bit toward contemporary and I’ve sold him on using LVL (Laminated Veneer Lumber) for the top with legs that are simple to make; he wants inexpensive and quick. The most time spent – at least I hope it takes longer than other parts – is time building a pencil drawer.

I took two hours to rip, square and assemble the pieces of LVL for the top one night after work. That includes time spent watching glue dry. The process is easy. Here are the steps in case you want to play along (or build something similar down the road).

2M4A2152I began with two LVL beams that were 1-3/4″ x 11-7/8″ x 10′-0″. After chopping the beams in half lengthwise, I set up at the table saw to rip each piece to 2-1/8″. Of course, one edge was ran over the jointer to give me a square edge to start. Using a 50-tooth combination blade, LVL cuts easy. The beams I purchased had a bluish painted surface, as you can see in the photo. That worried me little after making the jointer pass. Then after ripping the pieces and turning them on edge, you begin to see the final surface. To make up the 30″ in width needed to the desk, I ripped all four half beams, which produced 20 strips that were 1-3/4″ x 2-1/8″ x 60″+.

2M4A2153From the table saw, I returned to the jointer to true one of the two yet-painted edges to provide a solid glue surface. A single pass flattened all but two of the pieces. Those two pieces were areas where the lamination overlapped causing a bump in the face. I ran them a second time in order to achieve a flat face. You still see bluish paint in the left-hand photo because only one face has been flattened (all faces run over the jointer knives are downward facing, waiting for the planer.

2M4A2156A ride through the planer was so easy. All I needed was to flatten the second face for glue. The planer I used is setup with a spiral cutterhead. Even though there were no problems with the three-knife arrangement at the jointer, the planer surface was smoother. (This is why, when asked, I suggest that the planer have the spiral cutter, but it’s not that important on your jointer – the jointer is seldom the last surface of your work.) The first pass was great except for, you guessed it, the two pieces that needed the extra pass at the jointer. When those two were feed through the planer, the final surface was untouched in a couple places. A send pass through the planer was required, but only for those two pieces.

To my surprise, the most difficult process in assembling the two planks for the top was the glue-up stage. Spreading glue on the 19 pieces (yep, I had one strip left over after attaining the 30″ width) was a pain. 2M4A2159I decided to lay the strips out as if I were gluing panels for a case side. With the finished face up, I then rotated each piece to a glue face. With the pack tight together, I squeezed glue up and down the face leaving small lines covering the surface. I spread the glue using a thin scrap of wood. Scraping along the length was no good, but across the pieces worked like a charm. With one side gooey, I flipped the strips abd slathered up the second side. I was amazed at how sticky the pieces were as I tried to align the ends – I needed a mallet to move the individual pieces. Than goodness I assembled the 19 pieces in two separate groups. When finished, I added clamps and let the half-tops set. All in all, I used almost 3/4 of a quart of glue.

Out of the clamps in 45 minutes and all that was left was to clean the squeeze-out off and make a pass through the planer to level the two surfaces. When slid together – I still need to assemble the two halves – you get a good idea of how the top looks. My guess is it’s even better when a bit of finish is applied. Next week I’ll walk through the legs. Get it?
