Biscuit joinery can be tricky, since there are several different sizes of biscuits available, and it is important to get install enough biscuits to make the joint secure and strong, but not so many that you compromise the wood by cutting too many slots. Picture frames are a common place where #0 biscuits are used, and #0 biscuits work well in narrow applications, such as joining narrow rails and stiles on cabinet doors. Once you’ve determined the positions for the edge biscuits, you can calculate even spacing for the biscuits between the edges.
Because biscuit joints are easy to mark out and quick to cut, using one almost seems like cheating. The safest way to cut biscuit slots is with a biscuit joiner. The oversized slot lets the biscuit move slightly, enabling you to tweak parts into perfect alignment.
Once you’ve determined the positions for the edge biscuits, you can calculate even spacing for the biscuits between the edges. “(As a rule of thumb, place the biscuits about 6” apart. As a general rule, try to use the largest size biscuit possible, as this will provide the greatest amount of strength to the joint.
Biscuit joiner spacing refers to the distance from the edge of the biscuit to the point where it meets the wood. The biscuit joiner spacing’s width is between 1/16″ to 1/4″. Biscuit joiner’s spacer can be used as a guide, but it won’t always guarantee that your joints will end up perfectly aligned. A biscuit joiner spacing is a distance between the hole cuts which is equal to the width of the biscuit.

How many biscuit joints do I need?
Two biscuits per foot is a great rule of thumb, but the goal is just to make the alignment task easier. So, if you have a couple of edges that are 24″ in length and are dead straight & perhaps you would only need two biscuits to do the job.
How wide is a biscuit joiner slot?
Standard cutter width is 4 mm or 5⁄32 in. One source uses 21⁄4 in for length. † Biscuits may also be referred to as plates.
How deep does a biscuit joiner cut?
When adjusted properly, the biscuit joiner will cut a slot 1/32″ deeper than half the width of your biscuit. The additional 1/32″ provides a little wiggle room, as well as room for glue. If it is set too deep, the biscuits will be too far embedded on one piece, and won’t deliver the holding power that we want.
What are the disadvantages of a biscuit joint?
Biscuit joints do not stand up well against other joinery methods. We won’t spend any time comparing with mortise and tenon joints because all other joinery methods pale in comparison when measuring strength. But, as an example, the use of dowels as opposed to biscuits is a step up in strength.
How thick is a no 20 biscuit?
No. 20 beech jointing biscuits for board thickness of 19mm. Ideal for softwoods, hardwoods, plywood and composition board.
How wide are wood biscuits?
Biscuits commonly come in three sizes: #0: 5/8 inch by 1 3/4 inches. #10: 3/4 inch by 2 1/8 inches. #20: 1 inch by 2 3/8 inches.
What causes the biscuit joint to tighten up?
The biscuits themselves are compressed and expand when they come in contact with white or yellow glue, thus fitting more tightly after glue-up than before.
Can you use a biscuit joiner to make 90 degree joints?
Biscuit joiners are great for when you want to securely fasten a butt joint on your woodworking projects. George Vondriska teaches you how to use the biscuit joiner to attach a shelf at a 90-degree angle to the face of another board.
Are biscuit joiners worth it?
Biscuits joints serve best as a quick and easy way to keep glue-up parts in alignment, and that they add appreciable pull-apart to strength joints that would be otherwise too weak to stand on their own – like butt joints and miter joints.
Why does the grain of a biscuit run diagonally?
Biscuits are made from compressed beech wood. The grain runs diagonally across the biscuit. The biscuit is weakest along this grain line. When you install two biscuits in a joint, put them in with the grains running in opposite directions.
Can you biscuit joint plywood?
However, with a biscuit joiner, clean, unobtrusive joints can be made in plywood, with no visible hardware and clean edges coming together. Whether joined together at 0 degrees, 45 degrees or 90 degrees, all joints are clean and tight, as well as being strong.
What is a rabbet joint?
A rabbet is a recess cut into the edge of a workpiece. The piece that extrudes is called the tongue. A rabbet joint is the result of joining a rabbet to another piece of wood, typically to construct shelving and cabinet boxes.
Can you biscuit joint particle board?
Biscuit joinery was originally developed to build cabinet carcasses using materials such as particleboard and MDF. Biscuits are a perfect way to join these materials.
How can butt joints be strengthened?
Butt joints should be reinforced with screws or nails to strengthen the joint. Typically, this reinforcement is done by driving the fasteners through one piece of stock near the end and into the end grain of the adjoining piece of stock.
How long do biscuit joints take to dry?
In the right conditions a glue joint can be dry enough to take movement and light handling (no more than this!) in 20-30 minutes but when it’s cooler this could take an hour or longer.
