Julian Roslanowski Full Member Offline WR Rocks! Posts: 83 Rancho Cucamonga California USA PM 3520B	How is this made? May 9^th, 2016 at 5:05pm Can someone explain how these triangle pieces are made? Appears to me they are in the center of the segment. Is this just a matter of cutting a channel on the router table?

Reply #1 - May 9^th, 2016 at 7:14pm Julian, As far as how this artist did it, I would only be guessing. There are several ways this can be done and all of them are time consuming.(since there seems to be about 176 triangles) Router table and or jig, table saw, even a mortising machine, it's up to your imagination. Do you know who's piece this is?

I did not notice if there was a name. A mortising machine; I like that suggestion. That might be an easy solution. Thanks.

Julian

You found an excellent example of precision. The small triangles appear to be along a glueline. The "notch" can be formed with saw, router bit, etc, and be filled and trued with a tablesaw.

I am impressed with the precision of placement of the inset triangle in the center of each segment on each layer to provide such a smooth spiral and unity of pattern.

You picked a nice piece to analyze.

What will they think of nest! We should be precise in every piece we make. Any mis-alignment stands out and draws the eye to it. Every seam should have the offset or alignment. At least that is what I strive for.

Reply #6 - May 12^th, 2016 at 8:43am Last night I tried cutting some segmented pieces to see how easy or difficult this would be using a mortising machine. It worked, but the set up can be very fussy. This was more work than cutting triangle sections with the wedgie sled. I can make a very similar looking design using the wedgie sled.

I'm not sure if you did it this way just for a test or this is how you intend to do it.
I would cut several mortises in a long piece of stock and then cut the segments free, aligning the center as necessary.

Can you elaborate of show photos?

Reply #8 - May 12^th, 2016 at 11:49am This was just a test on some extra segments I had laying around. This photo is another test ring I made some time ago with the wedgie sled. The spacing between the triangles can be adjusted by changing the length of the segments.

If I was going to make this, I would probably go about it like this.
Find some wide stock, enough to rip 2 or 3 segment thick strips from.
First I would use the table saw to cut the 90 degree V-notch in the segments.
I would install a dado stack and angle to 45 degrees.
I feel a table saw would give me less tear out than a router bit since I'm cutting cross grain.
After all the notches are cut, I would rip the wider stock to proper size,
Then, using what ever method you like cut the segments from the notched strips.
You can use the V-notch as a stop or detent to register each segment. This will ensure each notch within each segment is uniform (centered).
Hope that makes sense

This is one of the benefits that this sled offers, with accuracy. Any other method has more set-up which equates to more potential for errors.

Segments cut with compound miter. The angle for the triangles then would seem to be the miter angle of the stave. Not 100% sure of this but that what it looks like to me.

Reply #14 - May 12^th, 2016 at 3:15pm Ed, I understand the process you described but I think the biggest challenge would be to cut each segment to ensure each notch within each segment is uniform (centered). Bruce; the grain direction in the photo I posted runs circular. The joints between the light and dark pieces are end grain to end grain.
