In the last article "Band-grinding machine from angle grinder on three rollers" A master from Finland told how to expand the functionality of angle grinders. In this article, the wizard presents a similar devicebut on two rollers.
Let's see it at work.
To make the fixture, the master used the following
Tools and materials:
- Sheet metal 3 and 1.5 mm;
-Drilling machine;
-Bending machine;
-Bearings;
-Vise;
-Welding machine;
-Fasteners;
-Hammer;
-Ushm;
-Tap;
-File;
-Milling machine for metal;
-Spring;
- A roller from a skateboard;
- Clamps;
-Press;
-Marker;
-Roulette;
Step One: Mounting Plate
The master made the mounting plate from 3 mm sheet metal. Plate length 150 mm. Width 50 mm wide and 30 mm narrow end of the plate. In the plate, the master makes a hole for installing the mounting of the angle grinder. One edge of the plate bends. Bend size 20 * 90 mm.
The master processes the mounting hole with a milling cutter, and then forms the teeth with a file. The diameter of the hole welds the ring. The mounting plate is installed instead of the protective cover.
Step Two: Tension Mechanism
The tension consists of two plates welded together (one straight line, the second L-shaped) and a guide welded to the mounting plate. The tension plates are inserted into the guide. A rod is welded to the plate, and to a guide sleeve. A spring is put on the rod and the plate is mounted on the guide.

Step Three: Mount
For quick installation and removal of the fixture, the master makes the mount in the form of two spring-loaded latches. The latches are screwed onto the screws of the gearbox cover.
Step Four: Bearings
In the upper part of the plate, the master installs thrust bearings.
Step Five: Roller
First, the master installed a roller from a skateboard on the shaft of the UShMki, then replaced it with a plastic pulley.
Step Six: Protective Cover and
Makes a protective casing.
Seventh step: plate
Makes and installs a perforated plate to reduce friction of the sanding belt.
Step Eight: Table Mount
From a clamp and a metal plate, it makes a mount for installing a belt sander on a table.
Belt-grinding device for angle grinder is ready.
In the video, you can see in the work a two-roller and three-roller device,
as well as the manufacturing process.
