And thats about it. Try it and let me know. Cheers. Anton
This is my first Instructable. Hope you will follow clearly. It will show you a step by step how to make a spiral out of a solid round piece of wood. Tools needed: Drill press, Table Saw, 10mm wood/steal drill bit,elbow grease, small round file, more elbow grease, sand paper, more elbow grease. Enjoy! by.....AntonD
To make a spiral, you need to work very precise. Start off by making a V-Block big enough for a 40mm diameter round piece to fit comfortably. See pic. This is where the table saw came in handy. The shape does not have to look like mine. As long as theres a big V-groove in it as to hold the round piece tight.
Step 2: Solid 40mm piece
Get a piece solid, perfectly round wood (or turn one on a lathe), of 40mm diameter and about 350mm long. My picture shows the ends already shaped. It's better not to, as this makes the next step difficult.
Step 3: Mark with pencil
Now you need to mark your solid piece of round wood. On both ends, find the center and divide in into quarters (Pic1). Draw lines between the four quarters (Pic2). Now, on the first line, make a mark 25mm from the edge, second line, 50mm from edge, third line 75mm from edge, fourth line 100mm from edge. Now you are back at first line, mark it 125mm from edge. Next 125mm etc. etc. Continue to the next edge.
Step 4: Cellotape
Now, take sellotape, or any other sticky tape of about 12mm width, and stick it all around the round wood only touching the markings you made in step3. This form a spiral. Next, stick another piece of tape all around, exactly in the centre between the spirals of the first tape. Notice the tape in the picture.
