A True Ringer for the Bandsaw double-sided tape ¾" plywood A True Ringer for the Bandsaw SOME OF THE SEGMENTED BOWLS I make sometimes have veneer accent layers that need to be cut and glued up with several segmented rings that make up the bowl. Since the veneer rings I use are frequently about 1/16" thick, it can be difficult to get tight glue joints because there is very little to clamp against. My solution was to make segmented rings out of ¾" dimensioned stock, and then use my band- saw to cut the veneer as a completed ring. However, it can be dangerous to crosscut large-diameter round pieces on the bandsaw, because most of the cut is unsupported and can twist on the blade. So, I created a vertical sledding jig specifically for cutting these rings safely and efficiently. My sled is made of ¾" plywood and measures about 8" tall by 12" long, but the size of your jig should be determined by the size of the rings you want to cut. It should be tall enough to hold the ring stable so it doesn’t “roll” into the blade. A matching 3" x 12" base is screwed to the bottom of the sled to create a right angle. (You can use triangular braces on the back of the sled, as I did, to ensure that squareness is maintained.) I attach the ring to a vertical sled with double-sided woodturner’s tape and adjust the bandsaw’s fence for drift, then use the sled to slide the ring along the fence to create several thin veneer rings After that, I run the rings through a drum sander to smooth them out in preparation for a faster, more accurate glueup. As a bonus, the jig doubles as an auxiliary fence for the bandsaw by simply clamping it to the saw table. — Larry Marley, Mission Viejo, Calif. Sticking To It WHEN I NEED TO TEMPORARILY ADHERE A PATTERN to a piece of wood to cut on a scroll saw or bandsaw, I attach it with adhesive from a removable glue stick that you rub onto the back of the pattern. There are several brands, including Avery’s, Scotch and Elmer’s, and they all hold patterns to the wood well and peel off easily, just as a Post-it note peels off of a piece of paper. It’s easy to use and not as messy as a spray-on adhesive. It only needs to be applied to the edges of small patterns, and on the edges and maybe several places in the center of a larger pattern. — Randy L. Wolfe, Owensboro, Ky. ILLUSTRATIONS: MARIA MELESCHNIG MARIA ILLUSTRATIONS: 48 WOODCRAFT MAGAZINE | 01.06 TIPS&TRICKS Corner Clamping Aid ½" dowel WHEN GLUING UP BOXES using band clamps, I like to put blocks ¾" x 3" x 3" plywood that help align the sides and spread the clamping force at each cor- ner. Lacking enough hands to hold all the blocks in place, while at the same time tightening the band clamp, drove me to devise this simple solution. Using some scrap ¾" plywood and ½" hardwood dowels, I made a set of four self-standing adjustable corner blocks. 1" square Start by cutting four 10" lengths of dowel. Cut the plywood into notch a dozen 3" squares, then cut a 1" square notch out of each corner. Drill a ½" hole in the opposite corner from the notch. It’s helpful band clamp to stack and clamp each set of three blocks when cutting the notch and drilling the hole, to ensure that each corner block is perfectly aligned. Glue a dowel into the bottom square of each set, leaving the other two squares unglued and free to slide up and down the dowel as needed. Because the base square is glued into place, the corner block set will stand in place, allowing me to concentrate on positioning and tightening the band clamps. — R.B.

  • Drill Bits 101 I've Used Dowels in a Variety of Woodworking Projects
    Drill Bits 101 I’ve used dowels in a variety of woodworking projects having bought myself a pretty decent doweling jig a few years ago. The jig itself came with a twist drill bit for each of the three dowel sizes. For my dowel joinery I often need to drill holes of two different depths; so sometimes it is handy to have two bits of the same diameter with stops set at the different depths. One day I inadvertently was using both a twist bit and a brad point bit and noticed very different results. For example, drilling into end grain was far more difficult with a brad point bit than with the twist bit. All of this got me wondering about the different types of woodworking drill bits. Hence my investigation into the family tree of woodworking drill bits. Note that many drill bits may be multi-purpose, but generally speaking there are different families of bits for plastic, metal(s), tile, and masonry, etc. The basic job of a drill bit of course is to stay centered and not wander, cut the wood to form a round hole, and eject the chips. Seems simple, but not so perhaps, which is why there are so many types of drill bits and even options on lips, lands, flutes, margins, and other design elements – details beyond the scope of Bevel Cut. Of all the types, the common twist drill, invented by Steven Morse in 1863 and covered in US Patent 38119 is the simplest. The V-angle of the tip can vary from 60 to 118 degrees, with the latter being most common in today’s hardware stores according to my own research.

  • EM-Tec VS42 Universal Spring-Loaded Vise
    Technical Support Bulletin EM-Tec VS42 universal spring-loaded vise Products #12-000220 and #12-000320 Description The EM-Tec VS42 universal spring-loaded vise clamp includes two reversible vise plates and four dowel pins which fit into the top of the brass sliding bar. The maximum clamping capacity between the vise jaws is 42mm. Available with either the standard 3.2mm pin or an M4 threaded hole for mounting on the SEM sample stage. Operation Consider wearing gloves to avoid contamination. • To open the EM-Tec universal spring-loaded vise clamp, pull on the side of the brass sliding bars. • Place the sample between the vise jaws and gently release the sliding bars. • The tension on the 4 springs will hold the sample between the jaws in the middle of the holder. • The universal spring-loaded vice clamp acts as a centering vise. The aluminium vise plates are mounted on the brass sliding bars with brass M3 screws. The reversible vise jaws comprise a smooth side and a side with three small grooves. The grooves are more suitable for small round samples or to hold sample with a rough side. For awkwardly shaped samples, the vise jaws can be removed and 4 dowel pins can be inserted in the brass sliding bar to clamp the sample between the 4 dowel pins. Optional vise jaws are available for large round samples. By using longer M3 screws, the vise jaws can be stacked to double the jaw height from 12 to 24mm. For samples which are thinner than 1mm, an alternative vise type holder with a screw should be considered.

  • Plain & Pre-Glued Dowel Pin FAQ How Do You Determine What Size
    Plain & Pre‐Glued Dowel Pin FAQ How do you determine what size dowel to use? The length of the dowel is generally determined by how much dowel can be inserted into the shortest member of the two piece joint. Twice this length is a common rule of thumb for determining dowel length. For example, if your shortest member is 1” thick and you know your safest drilling depth is 3/4”, then a 1‐1/2” dowel should be used. A 1‐1/2” length equates to two times the 3/4” thickness. The longer the dowel, the greater the holding strength. A similar procedure can be used to determine a proper diameter for the dowel. Generally, the diameter of the dowel should be no greater than half the thickness of the stock. For example, if the side panel is 1” thick, then you want to use a maximum 1/2” dowel. Incorrect hole depth or diameter create improper dowel joints by trapping glue or water at the bottom of the hole which is not properly distributed around the dowel. How deep should a dowel pin be inserted to be most effective? The longer the dowel, the greater the strength. The ideal joint has the dowel hole match the length of the dowel on both ends allowing the dowel to be inserted to the bottom of the hole. To avoid “blowout” on side panels, a small void of 2mm or 5/64”, is often left as insurance to collect excess glue or water in addition to allowing for variations in dowel length.

  • Mechanical Performance of Mortise and Tenon Joints Pre-Reinforced With
    Wu et al. J Wood Sci (2019) 65:38 https://doi.org/10.1186/s10086-019-1816-2 Journal of Wood Science ORIGINAL ARTICLE Open Access Mechanical performance of mortise and tenon joints pre-reinforced with slot-in bamboo scrimber plates Guofang Wu1,2, Meng Gong3, Yingchun Gong1,2, Haiqing Ren1,2 and Yong Zhong1,2* Abstract This study was aimed at examining the mechanical performance of mortise and tenon joints reinforced with slot-in bamboo scrimber plates. 27 full-scale specimens were manufactured with engineered wood and bamboo products using computer numerically controlled (CNC) technology, then they were tested under monotonic loading. The initial stifness and moment carrying capacity of joints with diferent reinforcing confgurations were obtained from the established moment–rotational angle relationships. It was found that the initial stifness of the reinforced mortise and tenon joints increased by 11.4 to 91.8% and the moment carrying capacity increased by 13.5 to 41.7%, respectively. The total width and grain orientation of the reinforcing plates had signifcant infuence on the mechanical perfor- mance of the mortise and tenon joints. Fastening the plates to tenon with dowels was benefcial to the mechanical performance of the joints. The embedment length and adhesive type had no signifcant infuence to the structural performance of the joints. This study demonstrated the feasibility of pre-reinforcing mortise and tenon joints in new timber construction, and could assist to promote the application of mortise and tenon joints in modern timber structures.

  • Make Your Own Atlatl and Darts
    Make Your Own Atlatl and Darts For thousands of years before the bow and arrow was invented, people all over the world used a spear-thrower called an atlatl. Archaeological evidence shows that people in the Great Basin may have been using atlatls as early as 8,000 years ago. The atlatl uses leverage to let the user to throw a spear (also called a dart) faster and farther. Brought to you by: Archaeology (Antiquities Section) The atlatl is a shaft of wood that is basically acts like an extension of the arm. The end of the dart rests against a hook on the end of the atlatl. To throw it, you fling the atlatl with your forearm and wrist, thrusting the dart forward. A well-made atlatl, used with skill, can throw a dart 100 yards at speeds of nearly 100 miles per hour! This is a replica of an atlatl found in Rasmussen Cave in Nine-Mile Canyon in Utah. The originally is probably more than 3,000 years old. This atlatl is just over 21 inches long. A rock weight in the middle added balance and mass to the atlatl. The deer hide strip might have helped stabilize the atlatl in use, or it might have been a charm or just a decoration. This replica was made by Ray Thompson of Salt Lake City.
