Hello, dear readers and DIY!
Many of You do joinery, and there is often a need to level the surface on a very large workpiece. Of course, this operation can be performed using different machines, and how to be with a minimum of tool?
In this article, the author of the YouTube channel “J-woodworking목공일기” will tell You how to make a special jointing tooling for manual cutterwith which you can align the surface dimensions of workpieces.
This project is fairly simple to manufacture, it is desirable a circular saw.
Sheet plywood 12 mm thick
— Pine timber Board
Orange oil, paraffin
— Sandpaper, screws on wood.
The tools used by the author.
— Manual mill, milling Cutters under 6 mm shank
— Circular saw
— Nailer electric
— Screwdriver, drill bits for wood with countersink
— Technical fan
— An angle grinder, disc grinding head
— The combined angular range, Japanese saw
The process of making.
The basic material for the manufacture of this fixture will serve as a pine Board.
First cut two identical rectangular parts of the supports for guide from the Board 50X150 mm.
This and the following operations are performed using a 90-degree cradle.
It is the width of Board used will depend on the maximum possible thickness of processed products.
Then for the two parts of the guide and a pair of jumpers to cut pine timber 25X50 mm.
Two parts of the guide are made the same length as the first, of timber. They are made of a sheet of plywood 12 mm thick.
The author already had any scrap and he cut from it a strip a little less than half the total width.
It remains to adjust the width of the second strip, cut its edge.
Next, a long blank of lumber is pressed against fence circular saws, and its lateral part is being targeted by neylerem plywood strip. Both parts must form an angle of 90 degrees.
Having prepared both sides, the author makes a pilot hole along the line of connection details by using drill bits for wood with countersink.
Now it is possible to strengthen connections with screws on wood.
Sole a router is installed between the edge of the teeth of the saw blade of the circular saw blade and parallel fence. Sole almost is clamped between them.
After that, from the unnecessary cutting of plywood is cut out a rectangular part. In the end it has a width of the sole of the router.
Two short cropping of timber laid on the sawing table or workbench, they are both guides of the area “plywood side” down.
Between the embedded parts of the resulting template and the edges of the jumper are aligned with the edge of the area, located closer to the author.
The pattern is free to move along both rails. Before fixing them to the jumper, the pattern is shifted almost to the edge. Both guides are being targeted to the jumpers through the plywood.
The same operation is performed from the other side of the guides.
Drilling a pilot hole, the author reinforces the connection of the rails to the crosspieces with screws on wood.
Excess jumper cut with a Japanese saw.
The main part of the fixture is ready, we need to check the lack of clearance between the guide and the sole of a router. However, he needs to move freely.
Then under the edge of the guide inserted both the support block and screwed to it with screws.
Several long screws the author is driving at an angle through the blocks in the lintel.
Here’s a dimensional piece of wood will serve for tests of fit. Over it is mounted a snap.
The author almost forgot one of the important points.
Definitely need to grind all surfaces of the rail with sandpaper, paying special attention to the parts of the guide in contact with the sole of the router.
Then you need to impregnate the wood with oil to reduce friction. The wizard uses for this orange oil. It’s certainly a rare thing, we simply get a linen, or rosehip oil.
After absorption of the oil surplus to be deleted, and additionally apply a layer of paraffin, warm it with a Hairdryer.
For surface treatment will be used to mill dovetail. This set of cutters it is under number 18.
Now, putting the necessary departure of the cutter, and slide the router along the guides, the wizard removes a layer of wood. After each passage, the whole superstructure is displaced to a distance a little less than the cutter diameter.
Dust and chips and thus actually formed quite a lot, is to use the dust extraction system.
So, after completing a dozen passes in both directions, the surface is aligned. Remains post processing, for example, a grinder with sanding disk attachment.
At the possibilities of such a device is not limited.
You should also think of ways to adjust the guide height.
I thank the author for advice on how to make simple but useful tools for the carpentry workshop!
All good mood, sound health, and interesting ideas!
