There are numerous ways to modify a half lap. Some involve elaborate cuts and may even include a wooden key pin to secure the joint. The less complex joint retains the traditional parallel and perpendicular cuts and is easier for the novice or beginner. If your fence is made with metal poles, you can find metal pole extenders that will slip right into the fence posts, like these extenders at Home Depot. The fence post options for a removable post like this are nearly endless. You could use this as a fence post for demountable panels or as a bollard. You can make your post any size you like as long as you can find the right size pipe for your sleeve too, and you can make your removable fence post any height you need for the job at hand. Separate the joint, apply the compound evenly, and then reseat the two pieces using several through bolts to hold the alignment. As the bolts are tightened, the viscosity of the glue makes the pieces want to slide out of alignment, making clamping difficult.

To make a half-lap joint, measure to find the centerline of the two pieces and mark both sides at the end and near where the cut will end to form the seat. Measure from the end and mark the desired length of the cut and mark it on both sides and pieces. While the depth is always half, the length of the cut will depend on use and compliance with local building codes. Go ahead and place the extension into position. Before you will screw it in use a level to make sure the extension is as level as you can get it. This is a really important step as not making sure the extension is in place will cause problems for your fence later. 6. Screw The Extender Into Place

First, it’s easier to install your sleeve plumb and level (which is essential) if you have a sturdy base for your sleeve post. It also makes it virtually impossible to pull your sleeve post out of the ground once the concrete around it is set. When applied to posts that meet the requirements of BS8417:2012 - UC4 (Use Class 4). See guarantee for details Joining 4x4s together to extend their length can be as easy as a butt joint or as complex and elaborate as a keyed, double tenoned scarf joint. However, some cuts are better done where the timbers can be rolled easily and joints tested for alignment and fit. When working on posts under load or limited space, simpler connections are better. You should paint the extensions with the same steps that the original posts were painted, to ensure that they look as exact as possible. 8. Your Fence Is Ready For Panels

That’s about it when it comes to our simple DIY removable fence post design. As you can see, it’s relatively easy to manufacture, lends itself to several applications, and can be manufactured from readily available materials.A hollow 10” to 24” metal pipe, 1” to 1-1/2” in diameter, inserted into a hole drilled vertically into the center of the ends of the two 4×4 to be butt joined, provides additional lateral reinforcement. The pipe is secured into the vertical holes with construction adhesive. Two 1/2″ through bolts are inserted into the top and bottom post pieces in holes bored through the wood and pipe. Lengths of 3/8” to 1-1/4” dowels can be used to add lateral strength to butt joints. Carefully measure to bore and align 1 to 4 holes in the ends of each 4×4 and drill the holes between 1” and 3” deep. Cut the dowels to lengths of 2” to 6”, sand the cuts, glue, and tap into place. There are several options for removable fence posts on the market, and one of them might well meet your needs. However, commercial options are often more expensive, more complex and have a longer lead time. So, if you just need a simple, fast solution, it’s sometimes better to manufacture it yourself.
