You would need four pieces of hardwood, having a thickness of 3/4 inch. You can keep the width and length of the column up to your desire.
Now you will require eight baseboard pieces with a thickness of 3/4 inch and bend the end of every piece at the angle of 45.
Use the table saw at an angle of 45 degree and cut the edges of your pieces. Remember that the edges at 45 degree will help you in making a good shape of the fluted column and will fit each other.
Now you can put the saw away and use wrench. To put nuts into the wood, you would have to take help of the wrench. You would have to insert holes at the edges.
Now you should take help from the blade and cut your column pieces at a straight angle. Make sure that the blade does not move and hold it firm while cutting.
Now you should attach all four pieces together. It should be vertical and straight. You can tighten all four corners.
Now you should wrap all four pieces together and your fluted column is ready.
