Zig-Zag Fold: Helix

23
Lefferts Manor 1909

See

measured drawing. I created a

spreadsheet to calculate piece dimensions. Woods are mahogany (or is it cherry?), maple, and quarter-cut American white oak. The field wood here is diagonal fingerblocks of nine strips of 1-3/8" × 12-3/8". Note when wood strips are only 1-3/8" wide, they only get a single nail across.

Ditmas Park West Year?

Pattern border is 3-7/8" wide. Bands are 2-3/4" wide. Surrounding is 1" mahogany and 1/2" oak. Inner field is straight fingerblock with 1-1/4" slats in a 12" square.

91
Crown Heights South 1913

This is the same pattern as the previous. And the same dimensions in its

spreadsheet. Inner field is fingerblock parquet with 2" wide slats in a 12" square.

83
South Midwood 1897

Unfortunate seam. In

Flattened Helix spreadsheet enter 2.75" for the width of strips, and 7/8" and 3/8" for the height of the trapezoids. But this is not really the same as the above. This has single blocks [which have split] for when the ribbon is showing its back. Inner field is fingerblock laid straight with 1" slats in a 12" square. Outer field is 2" wide random length slats.

Oshkosh Designs 2015

Custom made for Park Slope kitchen. Oak, maple and American cherry. There should have been an oak slat between the border and inner field, but it was forgotten at installation. The second mistake made was stainless steel nails were inadvertantly purchased and used. Now the nails will stay shiny, and they shouldn't. The third mistake is the corner block triangles should be a mix of oak and maple. Inner field is diagonal fingerblock with 1-3/4" wide slats in 8-3/4" squares.

Crown Heights South 1913

Pattern border is 2-7/8" wide. Rectangles in pattern are 1-3/8" × 2-5/8". Side border strips are 1-5/8". Can use

Folded From Side-to-Side

166
South Midwood Year?

Very unusual to have a striped ribbon. Nice for a change, though it kind of fades away Maybe better if the ribbon colors were reversed. Mahogany strip is 1/4". Maple sides are 9/16". Giving a total ribbon width of 1-3/8". Pattern border width is 5-1/4". Surrounded by 1-3/8" oak, 1/2" mahogany, 2" oak. Inner field is 2" slats in diagonal 8" fingerblock.

Bushwick 1897

Three woods: mahogany, maple and oak. See

measured drawings. I have a

spreadsheet that calculates the sizes of all pieces based on a given strip width. Inner field is fingerblock parquet in 12" square.

44
North Park Slope 1880

This ribbon is the same as

Side-to-Side spreadsheet. Enter 1.5 for the width and 5.25 for the height. The direction of the fold is just reversed. Inner field is fingerblock parquet with 2" wide fingers.

43
North Park Slope 1880

A smaller version. This floor (and the other from this house) may have been added a couple decades later. This ribbon can be calculated from

Side-to-Side spreadsheet by entering 0.875 for the width, 2.625 for the height, and =13/16 for the corner strip width. This gives a ribbon width of 4-3/8" and a corner/border size of 6". Inner field is fingerblock parquet with four 2" fingers in 8" square.

229

Folded From Side-to-Side: Corners Without Bullseye: Center Quartered

16
Crown Heights North 1910

Compared to the above, this one has narrowed the width of the ribbon, and exaggerated the feature strips, which are unique here. This ribbon can be calculated from

Side-to-Side spreadsheet by entering 1.5 for the width and 3.5 for the height. The mahogany bands are 7/8" and the oak between them is 1-3/4". The field wood here has 1-3/8" strips that are perpendicular to the borders and mitered towards the center.

72
Midwood Park 1905

Strip width is 1-3/4". Ratio is 3. Note uncommon banding around pattern here.

Folded Into Circles

This is the JP Morgan Chase logo.

36
