To create a smooth interior door casing, it is essential to drive nails snugly to the soffit, allowing expansion and preventing distortion. Allow at least 1″ overlap of fascia where lengths meet, and cover the balance of the gable end with fascia trim and cut to make an overlap joint at the peak. Use items like Baseboard Super Glue With Activator, Wood Filler, and Franklin Stud Finder to achieve this. In a basic lap joint, boards are cut to length and lapped over each other, with a few fasteners in the middle to hold them together. This method ensures a uniform thickness and allows for easy and precise cuts without a guide.

What are the three types of lap joints?
There are five principal types of lap joints, namely full, half, cross, mitered, and dovetail.
What are the weaknesses of a lap joint?
Lap joints have disadvantages such as undesirable mechanical or aesthetic overlap, potential cracks and cavity defects due to incorrect welding speed, less rigid weld due to pivoting, moisture retention, fatigue cracking and corrosion on shielded areas, and lower tensile strength.

How do you mark out and cut a lap joint?
Half-lap joints are woodworking connections where two pieces of wood are joined by removing half the thickness of each piece at the point of intersection. This creates a flush, uniform thickness across the joint, resulting in a strong and visually appealing connection. These joints are commonly used in framing, furniture making, and other woodworking applications. To create half-lap joints, clamp two boards side by side with their ends even, measure a distance equal to the width of one board, mark a square line across both boards, cut a series of closely spaced saw kerfs across the boards, and assemble the joint.
How to create a lap joint?
A lap joint is a simple and easy way to attach two pieces of wood together. It occurs when one piece of wood overlaps the other, and the “lap” is where these two pieces meet. The carpenter, woodworker, or DIYer fastens the boards to each other at the lap using mechanical fasteners like nails, screws, glue, or wooden pegs and dowels.
The basic lap joint is not very strong and not very impressive to look at, but it provides a bit of gluing area. Any torsion or torque can cause the joint to fail. However, there are uses for this joint and there are other versions that are much stronger. Trim the excess excess and lay the boards on a work surface to ensure proper alignment.
Does a lap joint need glue?
A lap joint is a type of joint where two or more boards overlap, creating a connection at the point of overlap. It is commonly used in woodworking, metalworking, and construction, offering a simple and efficient method for joining materials. Different types of lap joints include basic lap, half-lap, and dovetail lap joints. They are fastened using mechanical fasteners like nails, screws, glue, wooden pegs, or dowels. The basic lap joint is not very strong, but variations like the half-lap joint offer increased surface area for glue and lateral strength, making them suitable for woodworking projects and cabinetry.
What is the strongest lap joint?
Mortise and tenon joints are traditional woodworking joints with remarkable strength. They involve a tenon fitting into a mortise cavity, which can be reinforced with glue or wedges for stability. These joints are commonly used for creating robust and durable connections in woodworking projects like frames, tables, and chairs. The dovetail joint, an elegant classic, is a great choice for creating long-lasting, visually appealing projects. It involves cutting interlocking pins and tails into wood, resulting in a strong, tight-fitting bond. This joint is resistant to pulling apart, making it ideal for drawers and furniture pieces.
What tool is used to cut lap joints?
This article provides a fail-proof method for cutting accurate and consistent half lap joints without the need for a dado stack or elaborate jigs. The method involves using a table saw, crosscut sled, combination square, quick-grip clamp, and a spacer with the same thickness as the saw blade. The author explains that the method is effective and doesn’t require a dado stack or elaborate jigs. The spacer can be made to be the exact thickness as the saw blade, and the author will demonstrate how to make it. This method is ideal for those who have experienced frustration with hit-and-miss results when cutting half lap joints.
What is the gap for a lap joint?
The presence of a gap in the lap joint can reduce stress concentration at the root region. The optimal gap size is 0. 3-0. 6 mm, achieving 100 joint efficiency. Beyond this size, joint strength decreases. The study uses cookies and copyright © 2024 Elsevier B. V., its licensors, and contributors.

How much should a lap joint overlap?
To ensure joint strength, aim for an overlap width three times the thickness of the thinner part. This lap length should be three times the thinner part’s thickness.

📹 How to Make Your Own Shiplap
In this video I demonstrate how to make your own shiplap It suits well for the farmhouse/rustic style of decorating. MY WEBSITE: …
nice work as always. have been doing construction close to 40 years. ship lap made more famous from chip n Joanna gains, but was always taught that real ship lap is like lap siding on a house, no space. Nickel slot is whet you are doing, cause years ago they would space the boards with nickels, cause they are the thickest coin with a smooth edge. tell me what you think. lap means over hanging the piece below. still great job.
Another great article!! I like the shiplap look, as long as it isn’t overkill!! I do wonder how long the craze will last. I do have two quick questions. For wainscoting a narrow hallway, would you see any problem with removing the lower section of drywall and putting the MDF backing directly on the studs? Trying to not make the hallway any more narrow. Also, think you mentioned using Bondo as hard filler in a article, if so, which type? Just trying to find the best solution for filling a screw hole in a door jam. Thanks!!
Nice router table, you’re working smarter not harder. Have you ever considered using a momentary foot pedal or hang a panic switch to start and stop some of your tools like the router? You wouldn’t have to keep reaching under there. You’re skills are already great at your age, you can only get even better.
i would qualify your comment ‘if you are familiar with woodworking you will know 1 x means 3/4’ If you reference to woodworking ‘in America’ that may be more accurate. I think America is the only place that doea not aeem to use actual measurements. At least here in Australia we use the actual size of the material. Anything else would be false advertising. article is easy listening and informative. nice job
I’ve been binge perusal your articles, love em, very helpful. A way to take this technique further to achieve that 1/16″ to 1/8″ gap between the boards instead of using your ruler. After you run both sides through the router like you did, run one side through the table saw and trim that desired gap (ie: 1/8″) and now you can just stack the boards on the wall faster without having to shove the ruler in between and constantly run it down board. I’m about to finish my kitchen renovation and I’m down to base and crown molding and I’m looking forward to using a lot of your techniques, thanks.
I recently subscribed to your website and really appreciate effort you are putting in on each project. I enjoyed this article and thank you for the details. My wife is a HDTV junkie perusal the Joanna Gains design style and has become caught up in the Ship Lap craze. What type of wood do you prefer to use for making your own? Also, do you recommend wood or MDF? Thanks again for taking the time to share your knowledge.
Make the gap smaller than you actually want to end up with because real wood will shrink over time adding about 1/8″ more to the gap width. You can even paint the wall black before installing the wood and install the wood without the lap joints. Just install the wood pieces touching each other and over time the shrinkage of the wood causes a gap and the black wall underneath the wood makes it so you don’t see the wall through the gap. This technique works especially well with a stained finish on the wood and makes a great looking wall without the routing.
Hey can I point out one thing, on the gap… The rabbit on the top, at the wall side is supposed to be at 5/8″ deep so when you come with the next board, with the bottom being a 1/2″ rabbit..or top desired depth, the gap is automatic at 1/8″ ..or desired gap size (the thickness of a nickle) another name for shiplap is nickle gap. Its actually easier because they drop together without using spacer, it just bottoms out with a gap. So there is a functional top and bottom (good side) to each board
You note that if there was to be no space between the boardsthen one should not waste their time making the lap joint, then when joining the boards on the long end without a space for the seamless look you lap the ends. Is this for strength? Would the length-wise joining of the bottom/top board not be sufficient?
I do pretty much the same thing, but I make the cut a hair bigger than 3/8 because there is so much variation in the wood. It’s better to cut out a little more and they will still look flush than not cut out enough and the one board is sticking out a little. I also bevel the edges when sanding the boards down. Most people put shiplap on their walls, but I used it on my ceilings on my first floor. Stained and varnished knotted pine, but kept drywall on the walls. My only problem with shiplap is you have to face nail it, where tongue and groove nails are hidden.
Did a big custom home over the winter out here on the east coast and the home owner asked for horizontal ship lap on a 16′ X 50′ wall so i did it, and a couple days later he came back and said he made a mistake and wanted vertical. Destroyed most of it coming off the wall because it was stained already. Started from scratch lol
I used my table saw and a dado blade with a sacrification mdf runner to get the dado tight. Worked fast but i noticed I had a few odd boards that road up as I was milling them. In hind sight I wish I did the router table. I thought the process would burn up the router bit, bit taking so much material. Wish I saw this 1st. Still turned out great but I like the router option…
Thanks, you gave an excellent explanation of the process. I am doing an indoor home sauna build, and going to shiplap the exterior rough cut boards that I have from trees cut from our land., I’m doing the shiplap as an improvement to the insulation, and using purchased T&G cedar inside. Thanks for your thorough explanation.
That fly away shot at the end was amazing. At first I thought, WOW what an incredible house, but when I saw it surrounded by 20 others just as nice that were only inches apart, I was kind of sad… such beauty almost seems plain when it’s not in contrast to something like open space, nature or I guess ugly houses. This is why I don’t like cities.
Love your articles man, im a framing Carpenter, i can pretty much build a house from start to finish, but the most finish carpentry I’ve ever done is like elevations or exposed pergola. Very few trim work. I really like being precise on my work but sometimes I do get frustrated when my cuts are not real tight. I was interested in doing cabinet work, I’ve got a cheap router table, but some of the bits can get really expensive, do you have any tips on making fancy trim with regular router bits and table saw? Thanks
Thank you for very detailed explanation realizing that the majority of your audience are students. I also like the fact that you don’t waste time and get right into the subject without unnecessary long winded and drawn out explanations.Your articles are very educational, entertaining and you makes anyone actually try these things. Good Job.
You’re wrong about there being no need to put the boards flush. There is a very time honored reason they did exactly that. The boards will slowly dry out over time shrinking ever so slightly as the years go by. Especially true from moist summer to bone dry cold winter. THAT is why you put the boards tight, so that when they inevitably shrink, the lap joint still protects from rain getting in. Homes built with flush pine boards back in the 1820’s in New York and New England have shrunk to reveal gaps that were not originally there. This will be even worse by putting a gap in ahead of time.
