WAY TO ROUND AN EDGE USING A ROUTER
It’s a beneficial way to round an edge using a router of a portion of a material and can also be profitable for a few explanations. As it’s tiresome and tough to get a stable & constant edge from all the way around. So one has to use sandpaper which is suitable to round an edge. But a router which is much suitable cutter that can cut edge perfectly.
The advantage of using a router:
- The advantage of using a router is that one can form an edge with a stable radius in much less time.
- Another benefit of rounded edges is that these are less vulnerable to rapture or breakage and have a tendency to withstand to endure collisions with less evident or noticeable destruction compared to sharp edges.
- To shattering or fragmenting, a rounded edge is far more abandoned and will cause less injury to someone who will unintentionally hit in contradiction of it. This is the reason for what rounded edges are used for safety purposes such as the children’s item as toys or furniture, will generally have rounded edges for harmless use.
- A rounded edge is also handy as well as purposeful such as one portion of a drop leaf table.
- Again rounded edges are also considered as more lucrative and eye-catching compared to conventional design having a sharp edge using for some purpose. Rounded edges are often being used to the edge of guitar, shelves and chopping boards to provide attractive as well as soft & satisfying look.

Things to do before start
Some things should do before starting rounding the edge with a router. These are as follows-
A rounded or oval-shaped shaper
Have to choose a rounded or oval shape cutter or shaper containing the instruction guide which will be helpful to apply for better work. A rounded over cutter has s flat-bottomed form having bent sides that flatten toward the pole. The range of the rounded edge will be reliant to the radius of the shaper. The radius of the rounded cutter is between 6.34mm to 18.5mm
One thing has to keep in mind that the chosen radius will always be down to individual preference. Basically, for more sophisticated or delicate projects, shaper having a slighter radius is used to avoid eliminating the excess amount of material. For larger portions of the material, round over cutters round with larger range is necessary to efficiently moderate the edge. When utilizing especially expansive cutters you may need to utilize the router which is attached in the table.
The feed direction is also an important factor for the rounded edge. When you have to round the edge with a router outside of workpiece then you have to move in the anti-clockwise direction. Again its opposite while routing inside. That implies when you will rout inside, you have to transfer the direction to clockwise.
Orbital Sand to the edge of boards
To get a smooth surface, you should put orbital sand to the edge of boards before routing them. If you don’t, due to carelessness or irregularities the edge on the board will be transferred to the routed shape.
Patterned and sustenance workpiece
Before starting working, you should check the workpiece. The workpiece is sustained by scrap material or wood. The workpiece has to be smooth and straight. The cutter bearing instruction guide will pursue this edge and any defects that will be reflected in the cut. If your workpiece is predominantly thin, you can put some piece of material beneath it to give adequate allowance to the bottom of the shaper.
Some tools are needed for this DIY project that will save time and make the work easy. These are –
1. Clamp: To hold the small objects.
2. Dust mask: To protect the face from dust, a mask is essential.
3. Hearing protection: loud noise or sound of a router cause harm to ear and hearing problem can occur. So, hearing protection has to take for own self.
4.Hot melt glue gun: It’s required to secure small work
5. Orbital sander: For a smooth surface, orbital sand has to put on edge before routing.
6. Router: Through using a router, the desired rounded edge will be obtained easily.
7. Safety glasses: for eye protection safety glass is essential.
8. Sanding block: Sanding blocks helps to get a smooth surface.
9. A router table and feather boards: It’s used to make slender details with a router.

How to round over an edge
Some steps have to follow to round an edge properly with a router. The overall process can be summarized through these steps-
Step 1. Proper set up of router:
To start routing, the basic part is to set up a router. In addition, if you prefer round over shaper in the’s collet then you have to position your router on the edge of the workpiece by adjusting over an edge with a router and directing along the edge of a workpiece. At first, you have to pull out the router bit completely into the router collet. Then turn it back about 1/8in before shrinking the collet nuts. The direction of the router has to set. So you have to place the router on the edge of the workpiece and modify the height of the shaper to adjust the depth of the cutting range. Large shaper needs to be advanced and dynamic cut than the first finishing cut. They need to set for making advanced and dynamic cuts which eliminate a few millimeters of particles with each go until the finishing depth is accomplished. To cut a shoulder in peek point of your adjusted rounded edge, you should bring down the bit until the straight edge at the highest obtrudes from the base point. The range of the straight edge will rely upon the range of shoulder that you want. On the off chance, you have to uncover the bent segment of the router bit to round the edge.
Step 2. Start of routing
By setting your preferable cutting profundity, the router has to switch on, then dive the router until the profundity stops it, in addition, lock it in its place. Then move the router according to instruction guide contacting with the edge of the workpiece. At that point, have to move the router around the workpiece, possessing the guide bearing in contact with the edge. Do again this process. This process has to do until you have the desired size and shape of a rounded edge that you need by repeating the passes and resetting the shaper lower down each time.
Step 3. End of routing
Now it’s time to end the routing process when the
desired size is obtained. Have to switch off the router and keep it aside when
rounded desired edges are found. Now examine and check your workpiece for any
zones that may require routing going over once more.
Things that have to keep in mind during routing
1. To prevent the router from slating or sloping you should press the base part of the router tight to the wood surface. A sloping router will cut an unequal shape.
2. Carbide bits are more suitable than steel bits as it persists for a long period and marks finer cuts having less effort. So, it’s better to replace the remaining old steel bits with modern carbide bits.
3. It’s important to use a special solution to clean the blade and bit to wash away wood pitch. It’s available at any woodworking stores.
4. A deep outline slashes in two or three narrow passes to avoid burns and prattle marks. So one should fix a thin router depth to rout all edges & regulate the router for an intense cut.
5. It’s helpful to lock small pieces in clamps. As small parts are difficult to rout so it’s good to lock objects to clamps to fix chunks to your workbench to hold the strip of wood.
