Hello, dear readers and DIY!
Surely each of You tried yourself to sharpen knives or tools. One of the most important moments in this case is the exact observance of required angle of sharpening.
In this article, the author of the YouTube channel “JSK-koubou” will tell You how he made a table for a grinding machine with adjustable angle, and distance from the grindstone.
This fixture is easy to make and fit its size to almost any grinding machine.
Sheet plywood 12 mm thick
— T-shaped guide rail, square nuts M6
— Screws with wing head
— Steel tube of 4 mm diameter
— Screws, nuts, washers M4 screws for wood
— Mortise nuts M6
— Double-sided tape, sandpaper, glue Titebond II.
The tools used by the author.
— Clamp, screwdriver
— Circular saw, grinding machine
— Drilling machine, drill bit with countersink
— Twist drill bit wood screw head
— Manual mill, straight mill wood
— The circular attachment for a router
Orbital grinding machine
— Japanese saw, ruler, square, pencil, hex (inpussy) wrench, screwdriver, pliers.
The process of making.
The author has shared her outline of the drawing, without specifying the size, because in any case you need to adjust each machine individually.
The basic material for tables, supports and grounds will serve as sheet plywood 12 mm thick. Instead, you can use the PCB.
All rectangular blank of master slices in a homemade vertical sawing device for a hand circular saw. By the way, very interesting solution to save space in the workshop.
Two sidewalls that are attached to the bottom of the table, and adjust it to tilt, you need to cut two arc-shaped groove.
Drilling machine wizard makes two holes, using a twist drill bit for wood with a screw head of 6 mm in diameter, at the ends of the groove. These openings serve for the entrance of the mill.
Another 2-mm hole is drilled in the center of the circle sector which will be the slot. It is necessary for the spike circular nozzle.
The workpiece is fixed on the sacrificial Board using double-sided tape. This technique allows for further processing of the Fraser without the risk of damaging the countertop.
Manual router set the circular snap-in. With her help, straight cutters on wood, the groove in several passes. After that, the radius increases, and cuts the corner.
Such a circular nozzle of a router You can do by reading the following article.
Such parts master does two things, removes from them the remnants of double-sided tape. Then rounded the corners and the sides, and also removed the burrs on the orbital grinding machine.
Hole prepared for the edge of the circular nozzle, it expands to 6 mm.
The author also made two stands in the form of a rectangular trapezoid with base width of 150 mm and height 120 mm.
In each rack of prepared response mortise holes for M6 nuts, and bushing diameter 4 mm.
The rectangular base of stanochek cut from the same 12mm plywood size 150X130 mm.
From the edges of the base, the author retreats 12 mm, and attached to the first rack. Excess adhesive is immediately removed.
At the time of bonding pillars between them set the partition.
After drying glue the baffle removed. These places of connections it is necessary to reinforce with screws or nails to strengthen with the help of nailer.
In the Central holes of the uprights and swivel of the marginalia inserted into a sleeve of 4 mm steel tubing. Through it is threaded a screw and lock nut with padded washers.
To fix the table to the desired angle can be here are using bolt M6 with a wing head.
The upper edge of the rotary parts are exposed parallel to the tabletop and glued the table.
The angle of the table can be adjusted from 0 to 50 degrees.
Given the characteristics of the hull structure of a grinding machine, the master had to cut a section of the rotating part. With this task perfectly cope Japanese saw.
The machine is removed from intended for his cabinets, on the countertop is marked centerline along which will be located stand. Parallel to this line stick two strips of double-sided tape.
On the Central line following the alignment, the author puts a T-shaped guide.
Installing between the guide conductor a distance equal to the width of the aluminium profile, the conductor is attached to the table.
T-guide is removed and the milled groove for her.
It is important to check the planting depth guide.
Later in the guide and razzenkovyvajut drilled holes for screws with countersunk head, and it is secured in its place.
In T-track on the move two square nuts with M6 thread.
It is to fix a table for T-track with two screws M6 with a wing head.
Of course, before final Assembly of the structure, all wooden surfaces should be impregnated with linseed oil or cover with acrylic lacquer, it is necessary to protect the product from moisture, and easy cleaning.
Everything is ready, you can return the machine to its place.
But for some reason I had to cut some of the details. Otherwise she would have rested in the case, and not allowed to tilt the table.
When the desired inclination of the table, it is necessary to move the grinding stone.
For samples you can sharpen the headgear from the plane.
Increasing the sharpening angle, the author handles the corners of the blade. Before sharpening it aligns the surface of the stone.
And here is the result attained by manually is very difficult.
In terms of design improvements, it is recommended to apply on the surface of the table, 2-3 mm aluminum plate. It will last much longer than ordinary plywood.
Also it should cause layout of the tilt angle of the table at the sides, or use for setting the digital protractor.
I thank the author for a simple but useful device for a grinding machine!
All good mood, sound health, and interesting ideas!
