Greek Key Using Laminate Pro

I'm using Laminate Pro to create a Greek Key feature ring. Software and cutting 2nd generation is complete and product looks good. My problem is if I cut segments the horizontal elements will be different lengths. If I cut the upper horizontal it will have less length than the lower horizontal. So the Greek Key will not have equal elements. The design is for 12 segment feature ring. How do I cut segments with equal horizontals using the wedgie sled?
 
towards the end of the video it shows cutting the segments on a wedgie sled.

The method shown in the video is pretty much the way I did it years ago.

 
Thanks for the response appreciate the info. My Greek Key is produced with LaminatePro and creates a little different problem. See attached photo. I’m trying to figure a way to cut the segments retaining the horizontal bar with the same length as the lower bar If I cut at the center of the upper ones then the lower ones will be longer. I think that instead of cutting 12 segments I could cut 24 and glue them up for 12 keys in the feature ring. Would that work?

Can't tell from your photo if all the repeating units are glued into one long strip.
When I have done similar featured rings I only glue the repeating pairs together. So, in your example you would end up with 12 segment blocks

- What I call the dog ears would be cut off so you end up with a rectangle segment block.
- The blocks would be mitered on one side at a time by setting the bottom of the segment on the sled against the fence
(See the incra pdf for an explanation of the set up and cuts)
- The key would be to be able to miter the cut so it just angles into the front of the segment. You may want to sand to the final angle.
This should result in the horizontal bars being equal as possible.

LP is a great tool for working on designs using the lamination concept. It works with WTP or SP to bring in a new species. LP does not figure the miter angle needed to make the segment ring. that is done in WTP/SP. Think of LP produces the segment block. You still need to miter the angle to get them to fit into a ring.

Do you have a sketch of the Greek key you are trying to make? Off-hand, I don’t see how that second generation sine wave can result in what I have seen as Greek keys.

However, I have used that same lamination to make two designs that could be used in a feature ring. The reason I say two is that the first design is made using the Top segments and the second using the Bottom segments and both are attractive.

These designs are made by cutting the 2nd generation board into radial segments at 45 degree angles by setting the number of Repeating Units to 4.

I’m attaching the Lamination PRO file I used to create the sine wave board to make the top to two end tables. I don’t have pictures of the tables as I gave them as a gift, but I do have the SketchUp models I made prior to their construction. You could minimize the dimensions to make designs that could fit a feature ring.

The nice thing about using tops and then bottoms is that it uses almost all of the wood so there is little waste.

If you've ever made a bowl-from-a-board using a single slice, you can make a fancy bowl by starting with the design in my last post. The SketchUp drawing shows the board as a start and the BFAB results after turning without rotating the rings.

If you take this a step further using more strips of wood in the Laminate Wizard and starting with a 3rd generation board cut into 45 degree radial segments, the BFAB result would be stunning and something that has never been done before.

Thanks Lloyd, I believe you are correct more a sine curve than a Greek Key. I’ve looked at the repeating design and laid out some saw cuts. It appears to me that I can cut the stick of stock into 24 segments. If the cut is made at the vertical leg of the design then each would have the same horizontal distance. Then gluing the 24 segments into a ring would yield the 12 repeats of the design. Will do that in the next couple of weeks and report back. Again thank you for all the suggestions, really appreciate your support and I hope to try your design on a vessel.
 
Jess, if you want to wrap this board around a bowl, I would first cut it into individual segments at the exact center of each horizontal run and then cut the angles onto each of those pieces. When you do this, you will lose 1/8” for each saw kerf so that needs to be taken into consideration when building the rest of the bowl. Doing this will also create a saw kerf in the middle of the design, but that will be better than trying to cut at the vertical elements which will be difficult to do and any errors will be very noticeable.

It is always best to make the feature ring first and then design the bowl to match that ring as it is the most time-consuming part of a feature ring bowl.

Thanks for all your help guys, I finally got it done. Had to take a break for opening day bass fishing. Appreciate your suggestions of alternative methods finally cut the feature ring into 20 segments and was able to get a passable result.
