Vertical Rigging Line Rack

	This is a description of the unit I built
                 to store  and dispense rigging line for my ship models.
	It is screwed down to a shelf under my work table.

	Base Plate
                The base plate is drilled for the 3/16" dowel pins as follows;
	All hole locations are central to the width and length of the baseplate.
	There are a total of twelve holes in the baseplate. They are all 3/16"
	except for the two mounting holes. I will leave those hole locations out 
                because they are dedicated to my particular unit. You can make yours to suit.
	Take the left end (facing you) and call it the X reference edge.
	Take the front side (facing you)  and call it the Y reference edge.
	At the intersection of the X and Y edges is our starting point for all hole locations.
                1. 6.000" X - .750"" Y
	2. 2.375" X - 2.000" Y
	3. 9.500" X - 2.000" Y
	4. 1.250" X - 2.500" Y
	5. 10.750" X - 2.500" Y
	6. 1.250" X - 3.500" Y
	7. 10.750" X- 3.500" Y
	8. 2.375" X - 4.000" Y
	9. 9.500" X - 4.000" Y
              10. 6.000" X - 5.250" Y

	Lower Bearing Block
	The Lower Bearing Block has a total of six holes.
	Two are for the locating dowels. They are 3/16" Diameter.
	Four are bores for the Flanged Ball Bearings.
                They are .688 Diameter by .219" deep from each side.
	There is a through bore of .375".
	That allows you to remove any bearing by using a wooden push rod ..365-.370" Diameter
	Pick up the X and Y location as on the Base Plate.
	1. .188"  X -  .750" Y Dowel Pin 
	2. .750"  X -  .750" Y Bearing Bore
	3. 2.750" X - .750" Y      "         "
	4. 4.750" X - .750" Y      "         "
	5. 6.750" X - .750" Y      "         "
	6. 7.312" X - .750" Y Dowel Pin 

	Spool Shafts
	Take the 3/8" Hardwood dowel and put it in the lathe chuck.
	Face it and then turn it to .312" diameter by .875" long.
	Break the edge slightly with a file. A small radius is good.
	Turn it around, face it to the 5.000" length.
	Turn it to .312" diameter by 1.125" long.
	Break the edge as with the other end.
	A slot .070-.075" by .156 Deep will be cut into this end.
	Central to the .312" diameter.
	Use a good mini table saw or a slitting saw in the milling machine.
	That slot is for the drive in the Rigging Line Rack Rewind Unit.
	Two holes will be drilled through the Spool Shaft.
	They will be .312" in from each shoulder
	 that was created when you turned the 
	.312" diameters on each end of the Spool Shaft.
	Use a # 55 drill (.052").
	That will allow you to start a line easily to wind it onto the Spool Shaft.

	Standoffs
	Take the 1/2" hardwood dowel and put it in the lathe chuck. 
	Face it off to provide a surface to measure from.
	Centerdrill, drill and ream for .188" dowel pin. 
	Drill it .625" deep. That will  be for the 1" dowels, and the top of  the Standoff.
	Turn it around and face off to the 4.500" length.
	Centerdrill , drill and ream for .188" dowel pin.
	Drill it .500" deep.That will be for the 1 1/4" dowels, and the bottom of the  Standoff.

	Flanges
	Cut some oversize ( 1.900"diameter ) circles from 1/8" sheet plastic.
	Mark off the center. Drill and ream a .312" hole in each circle.
	Put the circles on a mandrel in the lathe. 
	Clamp them together, and turn them to 1.875" diameter.
	Make a few extra...

	Upper Bearing Plates
	Cut two pieces of 1/4" thick plastic by 2.188" by 10".
	There will be a total of seven holes.
	Four are for the Needle Bearings.
	Three are for the pins in the top of the Standoffs.
	Pick up the X and Y reference edges as in the Base Plate 
	and the Lower Bearing Block.	
	1. .250" X - .250" Y   Dowel Pin
	2. 2.000" X - .750" Y Bearing Bore
	3. 4.000" X - .750" Y      "         "
	4. 5.000" X - 1.950"Y     "         "

	6. 8.000" X - .750" Y"    "         "
	7. 9.750" X - .250" Y  Dowel Pin
	I cut the Upper Bearing Plates as in the Photo(s).
	That allows access to the spools in the unit. 
	
	There is not one screw in the entire unit. 
	It was developed, designed and built with one goal in mind.
	To enable me to store, access my rigging line without having to use any tools....
