Shelf Layout Corner Pieces - Custom Cut

[Joe Satnik]

Dear All,

A poster had asked how to get the corner of his shelf layout to work. 

Others had suggested using CAD layout drawings, which would work but would need a learning curve.

Here are non-CAD instructions:

Note: "Inside" is away from the wall, "Outside" is close to the wall.
Note: Track radius is to center line of track.     

Create a corner piece by cutting a square CSL x CSL (CSL = Corner Square Length)

Cut a quarter circle (off the corner of the square) of radius IR (IR = Inner Radius) 
The center of the circle is one corner of the of the square.

Think of a square saltine cracker with a bite taken out of the corner.

SW = shelf width

TRmin = mimimum track radius

TBW = track bed width

DIEB = distance from inner shelf edge to track bed

IR = TRmin - TBW/2 - DIEB

CSL = IR + SW

Example:  Given 15" minimum track radius, 2" track bed width, and 3/4" inner edge to track bed distance,

IR = 15" - 1" - 3/4" = 13-1/4"

Given 8" shelf width,

CSL = 13-1/4" + 8" = 21-1/4"

Hope this helps. 

Sincerely,

Joe Satnik

Advanced:  Multiple Tracks

What is the max possible radius track on the same shelf corner above?

DOEB = distance from outer shelf edge to track bed.

TRmax = CSL - DOEB - TBW/2

Example: Given DOEB of 1-1/4" (gives a little more room between wall and track)

TRmax = 21.25" - 1.25" - 1" = 19" max track radius.

Hope this helps.

Sincerely,

Joe Satnik
