Chevron Vase Project
This is the first in a series of segmented projects I plan to do here. If you have questions or comments feel free to mail me. Bob
Here I'm going to describe step by step how to make a segmented vase using a first generation pattern. You can see more of my turnings at Out of Control Woodturning
This first project will be made using a linear laminate to create a chevron design.
First off be sure to follow manufacturer's guidelines regarding safety when operating power tools. Accidents can happen too quickly! If you don't feel comfortable don't do it. Find another way.
The photo below shows the liniar laminate used in this project. It consists of three boards. The 2 outside are white oak that are 1" wide x 3/4" thick.The center piece is bloodwood that is 1/4" wide and also 3/4" thick. Extra care is need when you prepare the boards. They must be square, straight and have parallel edges. The amount of linear laminate needed in this project is about 40" but you need to make it longer for safety reasons. Reason being when the piece gets short it is difficult to cut safely.
Now we need to cut the linear laminate. To do this you need either a tablesaw with a sled or a mitersaw. I'll be using a tablesaw. The picture below shows the saw set up to cut the linear laminate into segments. The sled is set to 45 degrees. NOTE: THE GUARD HAS BEEN REMOVED ONLY FOR THE PHOTOS. An alternative cutting method is on this page. This alternative method uses compound angles but is simpler to do.
This next photo below shows a stop block being used so you don't have to measure every segment. First mark the length for the first segment. In this project it will be 7/8". Slide the sled up to the blade.(saw OFF) Line up for the first cut and tighten the linear laminate in the sled. Now slide the sled back and put a block between the laminate and the tablesaw fence. Tighten down the fence. The fence must not be moved until all the segments are cut. Now remove the block and cut the segment. After the blade stops slide the sled back, put the block back in and slide the laminate over to touch the block. Tighten down the laminate, remove the block again and make the next cut. Repeat this process until you have enough segments. In this case we need 24 segments.
You should now have 24 segments that look like the picture below.
Next you need to flip every other segment over. You will see the zig-zag (chevron) pattern.
Now glue these together in twos. In other words we have 24 segments we want to change into 12 segments. Before gluing the segments you should tru the joints. Use whatever method works best for you. I tru every segment by hand using a 12" sanding disc glued to a piece of countertop (Sink cutout). I use the countertop cutout because it is very flat.
Next you need to miter both edges of your 12 segments. In this case we are making a 12 segment ring so the miter angle is 15 degrees. Choose whatever method you feel comfortable with for the mitering. It's VERY dangerous cutting small pieces with a tablesaw so use some sort of carrier to do your cuts. You can buy a carrier at a woodworking store or you can make one. If you don't feel comfortable don't do it. Find another way.
When you finish with the mitering glue your segments into 2 half circles. We use half circles so we can tru them. The chances of gluing all the segments together and having the joints match is near impossible. I also use the countertop method to tru the halves. The picture below shows the completed 2 halves and the countertop I use for truing. True and glue the two half rings.
