Whether or not we’re enlisting the assistance of scientists, interval furnishings makers, or school professors, we—the editors at Wonderful Woodworking—just lately got here to a realization about ourselves. We type of like breaking issues.
We should prefer it; simply check out all these completely different articles the place we smash, compress, or in any other case harass completely harmless woodworking joints, simply to look at them fail. Anybody would assume we had an actual imply streak to us.
The reality is, although, that the objective is at all times the identical—higher outcomes for ourselves and for you. We wish the furnishings you make to be robust, and the joints you spend a lot time crafting to face the check of time. So typically we escape the hydraulics and ask the scientists. Generally we get a bit of harmful. It is type of enjoyable, and the outcomes will be eye opening!
We push 18 standard body joints to the breaking level
By Douglas Moore, Thomas McKenna #203–Jan/Feb 2009 Subject#203–Jan/Feb 2009 Subject
When designing a bit of furnishings, how do you determine on the joinery? Chances are high aesthetics, effectivity, and accessible instruments issue into the choice. However so does energy. Wonderful Woodworking teamed up with a gaggle of analysis engineers to check 18 standard body joints and see which is strongest. We made 5 units every of 18 several types of joints in cherry, a species used usually by furnishings makers. The samples had been positioned in a servo-hydraulic supplies testing machine–basically a hydraulic ram hooked as much as a pc to report drive and motion–and damaged. Which of them had been sturdiest? The outcomes will shock you.
We take six sorts of glue to the breaking level, shattering some frequent knowledge within the course of
By Mark Schofield #192–July/Aug 2007 Subject
Glue is so important to woodworking that there are dozens of sorts and much of competing manufacturers. There’s additionally a number of “standard knowledge.” To see if that standard knowledge has any foundation, Wonderful Woodworking ran a check on six frequent sorts of woodworking glue — a conventional yellow glue (PVA), a Kind I waterproof PVA, a liquid cover glue, a scorching cover glue, a slow-set epoxy, and a polyurethane.
Make them larger, scale back gaps, and don’t spare the glue
By Dan Bollock #259–Jan/Feb 2017 Subject
Wooden researcher Dan Bollock broke greater than 150 mortise-and-tenon joints of various widths, lengths, and thicknesses to see precisely how dimension, match, and glue-up procedures have an effect on the energy of the joint. He discovered that width performs the largest function, however that size and thickness additionally make an enormous distinction. Not surprisingly, a joint that matches nicely is stronger. Additionally, the strongest glue bond was created by making use of glue to each the mortise and the tenon.
Be taught the science behind clamping, for excellent glue-ups
By Roman Rabiej #194–Nov/Dec 2007 Subject
For many woodworkers, the glue-up course of is an inexact science. However for wooden technologist Roman Rabiej, judging the success and potential longevity of a glue-up is just a matter of figuring out the clamping drive you want, selecting the right sorts of clamp, and inserting them the place they’ll do probably the most good. Rabeij explains the science behind clamping in phrases that may be certain that you method your subsequent glue-up with confidence.
Shocking outcomes floor in an evaluation of generally used furnishings joints
By Bruce Grey #148–Mar/April 2001 Subject
Utilizing the laboratory on the Wooden Science and Expertise Middle of the College of New Brunswick, Bruce Grey examined joints and talked to specialists about why joints fail. They examined conventional mortise-and-tenon joints, floating-tenon joints, biscuit joints, and dovetail joints for load, displacement, price of failure, energy after failure, and rigidity. He explains how the samples had been ready and examined and easy methods to interpret the charts. The article additionally provides a information to the anatomy of the joints examined.
