Pocket-hole joinery - Wikipedia

Make precise, square cuts. When making projects with right angles, such as cabinets or face frames, square cuts ensure square assemblies. Anything less will result in gaps or unsquare joints. If you cut stock on a mitersaw, tune it up as well. Plan your work, work your plan.

After cutting but before drilling, lay out project parts in the orientation you want, and then mark the pocket hole jig definition ppt faces, as shown below. Be sure to also draw other layout marks, such as where a middle rail lines up with the stiles.

Then drill pocket holes into the marked faces to prevent accidentally drilling into the best face. Grab the best grain. Drill pocket holes so screws pockeet into edge or face grain for maximum purchase; avoid screwing into end grain, as pocket hole jig definition ppt below.

These screws won't hold as well threaded into end grain. Instead, drill the pockets on the rail and drive screws into edge grain of the stile. Set the correct pocket depth. For strongest joints, set the stop collar according to your jig's instructions. Check this each time you use the jig to avoid accidentally drilling too deep. A corded drill bores a cleaner hole than a cordless one because of its faster bit speed. Excessive tear-out around the pocket could indicate a dull bit.

Keep a second bit on hand so you can switch to it when the first begins to dull. Smooth the way. Before drilling, spray the bit with a dry lubricant, such as Bostik DriCote, to reduce drilling friction and prolong sharpness.

Repeat after every 20 or so holes. Clear chips frequently. Pull the bit out when you've reached about half depth to clear the chips; then finish drilling. This reduces poket and bit dulling.

Match up different thicknesses. When joining boards of two different thicknesses edge-to-edge or end-to-edge, as shown belowset the pocket-hole depth for the thinner board.

If joining boards end-to-face or edge-to-face, such as in a table hope to the top, set the depth for the thickness of the board with the pockets, regardless of which is thinner, and then use a shorter screw if necessary. Choose the right screws. Coarse-thread pocket screws hold best in softer woods, such as pine, cedar, and poplar, as well as plywood; use fine-thread screws for hardwoods.

Choose the length based on the workpiece thickness, as shown in the chart below. Use fine-thread screws for hardwoods. Use coarse-thread screws for softwoods, MDF, particleboard, and plywood. Most pocket-hole screws come with an oversized washer head for increased contact with the pocket shoulder, but you can also get screws with a smaller pocket hole jig definition ppt head pocket hole jig definition ppt use with shallow pockets where a washer head would protrude above the workpiece surface.

For outdoor applications, choose stainless steel or coated screws. Never use drywall screws -- they break easily while driving, and their tapered "bugle" heads can split the bottoms definotion the pocket shoulders.

Don't forget the glue. Screws alone make a plenty-strong pocket-hole joint, but adding glue helps prevent a joint from opening up due to seasonal Pocket Hole Jig Definition Formula shrinking and swelling. Clamp across a joint whenever possible, see photo belowto avoid the parts creeping out of Pocket Hole Jig Definition Volume alignment as you pocket hole jig definition ppt up the screws.

Clamp parts to a perfectly flat surface so the front faces align. If one of devinition parts is offset, shim below it, if needed. When screwing an edge to a face, such defintion the table shown below, always clamp the assembly securely uig driving screws. Learn to drive a clutch. Although handy for driving fasteners, avoid using an impact driver for driving pocket screws. Because you can't see the screw snug up against the pocket's shoulder, the tool's high torque can easily strip out the screw hole.

Pocket hole jig definition ppt, use a drill or cordless screwdriver with an adjustable clutch, set to pull together joints without stripping out the holes. After I milled some custom oak molding, then stained and finished it to match the existing woodwork Skip to main content.

May 10,  · A pocket hole jig is a specialty woodworking tool that allows wood to be connected securely with screws. The pocket hole jig enables this by providing a fixed-angle hole to be drilled using a specialty drill bit. And, for different thicknesses of wood, the jig will adjust the hole up or down to allow for a longer screw to be www.- g: ppt. The Armor Tool Auto-Jig is changing the landscape of pocket hole joinery and the way you make pocket holes in your shop. Our system self-adjusting system will set your drill guide setting and drill bit collar based off of the thickness of the piece you're clamping (see video for demonstration). No more manual setting, measuring, or www.- g: ppt. If I put the pocket holes on the inside of this joint, the screw would be going towards the outside of the 2×2, giving the screw very little material to grip and a high probability of splitting. By putting the pocket holes on the outside, we are making sure the pocket hole screw goes into thicker material and minimizes splitting. 7.
