Standard 9′ cleated dovetail (with wood between the runners) features a lifting capacity of approximately 8,000 lbs and carrying capacity of 4,000 lbs.
How strong is a dovetail?
The dovetail joint is very strong because of the way the ‘tails’ and ‘pins’ are shaped. This makes it difficult to pull the joint apart and virtually impossible when glue is added.
What are the limitations of a dovetail joint?

For box joint, some people put a lot more fingers than it is possible to do with Dovetail. In this case, the gluing surface is larger, and the joint is likely stronger. Also, some find a way to hide a finish nail in the joint. Dovetail has the advantage of a mechanical lock independent of the glue.
Is a half-blind dovetail joint strong?
In half-blind dovetails, the tails are embedded in the pins board without going all the way through. They give you the strength of regular dovetails with uninterrupted grain on one side, which is why they’re often used for drawers.

What is the strongest joinery?
Mortise and tenon joints have stood the test of time for their remarkable strength. This traditional joint involves a projecting piece of wood, called a tenon, securely fitting into a corresponding cavity, a mortise. It can be reinforced with glue or wedges for stability for a stronger hold.

What is stronger dovetail or finger joint?
For box joint, some people put a lot more fingers than it is possible to do with Dovetail. In this case, the gluing surface is larger, and the joint is likely stronger. Also, some find a way to hide a finish nail in the joint. Dovetail has the advantage of a mechanical lock independent of the glue.

For this test, the box joint proved stronger. Plus, the box joint is strong in both directions, whereas the dovetails are useful only for pulling from one piece, but not the other. So really, to use a dovetail joint for the sake of strength is obsolete, mostly on account of the strength of wood glues.

What are the rules for dovetail joints?
The ‘pins’ are the bits of wood between the tails so there are two half-pins; one each side. The general rule is that they measure half the thickness of timber plus around a mm, so the two dots on the shoulder line are 7mm in from each edge.
