Hi I'm Luke Rogers from Tillamook Oregon

[lukerogers]

I'm a little confused I wanted to introduce myself and the only place I see to write anything is in new post. I hope this is the correct venue to do so.
I am new to segmented turning. I've been turning for about a year. I'm trying to do a southwest feature ring and I am having trouble figureing out how to do the cuts.
The following instruction are unclear to me I hope someone can help me figure it out.
Strip 1; 3/4" Holly.jpg
Strip 2: 1/4" Purpleheart.jpg
Strip 3: 3/4" Holly.jpg

To make the 1st Generation:
Cut the laminated board into 1-3/8" strips at 30 degrees.
Flip the left-hand strips left-to-right.
Width of repeating units: 2.75
To create the SW design, make a center kerf that is 0.125" (3.175mm) wide.
Make 3 strips on both sides of the center kerf that are 0.125" (3.175mm) wide.
Slide all top strips by one-half of a repeating unit.
Flip each strip of the SW design from top to bottom.
When it says cut a center kerf does it mean down the center of the generation one glue up horizontal? I dont see an angle mentioned so I assume this is the case.
I dont want to waste material so any help would be appreciated.
Thanks Luke Rogers

Hi Luke,

Welcome to the community.

With regards to the southwest designs, the width of the center kerf is simply the amount of wood that needs to be removed from the center of the board. In your case, since the design calls for a 1/8" center kerf, you simply need to use a 1/8" board and cut through the dead center of the board and you will have removed the 1/8" center kerf.

Removing a different amount is easy, once you understand how to do it. Let's say, for example, your center kerf is 1/2". What I would do in this case is first find out how wide the 1st generation board is. This is not a calculation that is made for you (although it may be in the next release. It is easy to find, though. Click the 'Clipping Region' box and then expand or contract the clipping region until it is just touching the top of the 'ears' and the bottom of the ears. You can type in a value in the clipping region when you get close. Let's say that the height of your 1st generation shows 3-1/2". All you have to do is subtract the center kerf from the board width (3.5" - .5" = 3") and divide that in half resulting in 1.5". Now move your fence 1.5" away from the blade and make your first cut by putting the ears from one side of the board next to the fence and then flip the cutoff around and put the other ears next to the fence. Once that cut is done, you have removed the 1/2" center kerf from the board. You now just have to cut the strips from each half of the board and follow the instructions of flipping and sliding.

Make sure you click the 'Show kerfs' checkbox as this will show you the exact locations where cuts are to be made on the board. As you change the width of the center kerf, it will be easy to see using the 'Show kerfs' view.

There is a PDF tutorial that will help you with your multi-generation lamination projects. You'll find it in the Software Tutorials category at this link.

Good luck, Luke and please let me know if you have additional questions.
