How to Build a Torsion Box Workbench Top
Why use a torsion box in a workbench?
The principle is to use less material more efficiently. The torsion box uses the properties of its thin surfaces to carry the imposed loads primarily through tension while the close proximity of the enclosed core material compensates for the tendency of the opposite side to buckle under compression.
How thick should a torsion box be?
All said and done, if you make the torsion box 2 – 3″ thick, surround it with a perimeter maybe 4″ high, and set it on a legs joined by stretchers, it’s not going to flex. People use hollow core doors all the time for a workbench top.
Does a torsion box need a bottom?
As Gabriel says, it’s not a torsion box without a bottom. Even if it’s only 1/4″ thick, it’ll add considerable stiffness.
What makes a torsion box strong?
What is the best material to use for a workbench top?
The strength of a torsion box comes from the connection between the edges of the outer frame and inner grid and the top and bottom skins. It’s not critical that the inner grid is perfectly spaced. However, it is critical that it is flat and true to ensure a perfect bond with the skins.
Is MDF a good workbench top?
In this case a sheet of 3/4-inch medium density fiberboard (MDF) is ideal. It is stout enough to hold any load, has a smooth surface that won’t scratch wood and can be easily flipped or replaced once the table top is too nicked up to work on. Add a coat of beeswax for a finish that will repel stains and paint.
How do you make a flat torsion box?
For a bench that extends beyond the frame of the workbench to accommodate vices or other clamps, MDF is an excellent choice. As well as having the strength to extend beyond the frame, MDF provides a flatter surface than plywood for woodworking use.
Why is it called a torsion box?
What is a torsion box bench?
As the name suggests, wave induced torsion is caused due to the unsymmetrical hydrodynamic wave loading on the port and the starboard sides of the vessel.
How do you make a flat work table?
How do I protect my MDF workbench?
Instead of having a conventional, solid top, this benchtop is a torsion box. It consists of grid sandwiched between a plywood top and bottom. It’s a proven construction method that’s strong, yet easy and inexpensive to build.
How do you make a wooden grid?
How do I make my workbench top flat?
How do you make a level work surface?
What tool will you use to flatten and smoothen the surface of a workbench?
What router bit to use for flattening slabs?
A tall workbench is good for detailed work, cutting joinery, and for power tool use. 34″ – 36″ (86cm – 91cm) tend to be the most common workbench height for woodworking. A height in between these two extremes tends to be the most popular, particular if you do a range of activities at your workbench.
