Introduction: DIY Highly Adaptable Belt Grinder
This instructable is ment for people with experience in engineering.
We used the following machines to make our belt grinder:
Laser cutter (wooden wheel and pulley)
It is also possible to build the belt grinder using less machinery, but then you have to buy some extra parts.
Step 1: List of Materials
Here's a list of the materials you need to build the belt grinder:
Tube profile 50x4mm:
Tube profile 40x4mm:
Tube profile 30x4mm:
220mm X2 (depends on the used engine)
Tube profile 20x2mm:
Square bar 10mm:
Steel sheet 10mm:
420x300 mm (in our case 2X 420x150mm)
Diameter 75mm X2
Steel sheet 8mm:
Steel sheet 4mm:
Nylon bar diameter 60mm:
Diameter 300mm X7
Diameter 170mm X8
Steel axle 25x490mm
Steel axle 20x50mm
Steel tube diameter 30 x22x2.5mm
Bearing 25mm X2
Bearing 8mm X4
Bar hexagon 36x950mm
Bar hexagon 17x180mm
Knob screw m8x60mm
Knob screw m10x30mm
Knob screw m10x85mm
Threaded rod m10x220mm
Threaded rod m8x50mm
Threaded rod m8x100mm
V belt 1025mm (exterior)
Step 2: Building the Basic Frame
D: 10x420x300mm (in our case 2X 420x150mm)
E: 40x354mm (mesured from far-side to far-side)
The parst G E and F are helt together with the threaded rod m10x220
Part A is welded to part C by drilling 2 holes in the side of part C
Step 3: Building the Adjustable Wheel
You need to weld a m10 bolt to part D to connect part I/F to it.
Step 4: Assembling the Wooden Pulley and the Wooden Wheel
B: Diameter 75x10mm
C: Diameter 30 x22x2.5mm
Using loctite make sure part C does not put pressure on the bearing.
Step 5: Building the Support Plate
Step 6: Building the Extra Wheel
A: Diameter 60x55mm
The nylon wheel is assembled in the same way as the wheel in step 3.
Step 7: Building the Part That Adjust the Extra Parts
You need to make this part twice.
Step 8: Building the Slider Profile
To fully clamp part A to the 30mm profile you need to make a slot in both sides of part A.
It is also possible to mount part A to the 30mm profile the same way as step 7.
Step 9: Building the Stand
