How to make a template for rounding corners with a router (improved version)

Hello, dear readers and DIY!
When making a wide variety of joinery – from a box to a table top – the task often arises of making neat rounds at the corners.
In this article, the author of the YouTube channel “JSK-koubou” will tell you how to make template for the formation of fillets at the corners of the workpieces.
 How to make a template for rounding corners with a router (improved version) How to make a template for rounding corners with a router (improved version ) This device can be easily made in a small home carpentry workshop.
By the way, in the recent in the article a similar template was already described, but it had only two working corners. It seems that exactly the idea was taken as the basis of this device.
Materials necessary for homemade products.
– Sheet plywood
– Screws or hairpin m3
– Knurled nuts
– Fast-curing two-component epoxy adhesive, sandpaper.
Tools used by the author.
– Manual router
– Thrust bearing cutters
– Dremel
– Screwdriver, drilling machine
– Forstner drills toothed
– Universal clamp for T-track
– Hand circular saw, orbital sander – Machine vice, hacksaw for metal
– Clamps
– Square, marking gage, compass, pencil.
Manufacturing process.
The first step is to select sufficiently long screws or studs with m3 thread.
Screw heads are cut off using a dremel .

In this case, its dimensions are 220 × 220 mm, but they can and should be selected for your tasks.

They will serve as side stops.
In each of the plates you need to make a pair of oval holes at the same distance as the pins are located from each other.

Of course, to protect it from moisture, you should soak the product with linseed oil, or cover it with acrylic varnish.
How to make a template for rounding corners with a router (improved version) As you can see, the stop can be moved to work on both sides of the template. In the previous template model, they were rigidly fixed to the base, and precisely because of this, there were only two corners instead of four.

The strips are pressed against the edges near the corner to be machined, and this structure is pressed with a clamp to the workbench.

The cut-out hole in the center of the template serves as a finger grip to press the template stops against the edge of the part.
