Step 1: Preview

Step 2:

I'm starting to make the first piece that will form the body. I use 18mm hard plywood. I glue 2 of them together and cut them.

Step 3:

I cut 6 discs of 182mm in diameter from lightweight plywood. I glue them together in the form of 3 + 3.

Step 4:

After refitting the bearings. I glue the parts and fix them with screws to form the main body. After fixing the engine, I put on the belt. Now I can energize the engine.

Step 5:

I do some turning and sanding to balance the main wheel. I make sure it is stable and vibration free.

Step 6:

It's time for the top wheel. I fix the M8 metals in place and sand the ends. I open the bearing housings for the upper wheel. After installing the bearings, I snap the upper wheel into place. After attaching the 50x1500mm sanding belt, I start the motor and do some sanding. I make sure the upper wheel is balanced. I give the proper shape by sanding the sides a little too much.
