Introduction: How to Turn a Old 4x2 (2x4) Into a Piece of Fine Woodworking
How to create a simple wooden bowl from a construction grade 4x2 (2x4)
Step 1: Getting the 4x2
Here is the piece of 2x4 i used it had some holes in it which i tried to avoid and i pit glue in the cracks when gluing up so they were not visible when the bowl was finished.
Step 2: Cutting and Glueing Up Blank
First cut the 4x2 into pieces so that the with matches the length. I cut the pieces into 12 inch lengths and had 6 pieces. I then glued them up with titebond wood glue.
Step 3: Attaching the Face Plate
With the blank glues and dried i found the middle and attached the metal face plate with wood screws.
Step 4: Truing the Back
With the blank mounted i turned the lathe to 600 rpm to find the speed i turn the speed up until the lathe starts to vibrate and turn it down a fraction from there. I then true the face up so it is flat. You have to cut it down a bit because the 4x2 have rounded edges which you have to cut out.
Step 5: Making the Tenon
With the back trued up i then cut the tenon. I use the bowl gouge and the skew to do this. It is important to make the tenon undercut to prevent the bowl from coming off. I cut the tenon to 50mm my jaws are 49mm so the bowl is securely held but doesn't run the risk of being marked by the jaws.
Step 6: Shaping and Sanding the Back
After i have cut the tenon i then use my bowl gouge to shape the back of the bowl. You can do this to whatever shape you want. With the shaping cut done i sanded from 80 to 600 grit with a drill sanding pad.
Step 7: Removing the Faceplate and Remounting
With the back done i remove the faceplate and remount the bowl. Be careful to mount so it is tight but not to tight to damage the bowl.
Step 8: Shaping the Inside
With the bowl mounted i start shaping the inside of the bowl. For this bowl i made it have a thin wall but you can do whatever design you want.
Step 9: Sanding and Finishing
When you are happy with the shape sand the same way as the outside. You can use whatever finish you want. I used a friction polish but you could use a oil or polly.
We have a be nice policy.
