Blinds, Shades and Shutters - Re-String Verticals

The cord broke and before I buy a new headrail, I was hoping to try re-stringing myself. If anyone has the proceedure, I am pretty handy and would like to try to avoid the cost of a new one. Nothing is wrong with this other than the cord.
Thanks for any help.

all headrails are a bit different but the idea is the same..

The best way to visualize whats going on in there is to draw a wide / short oval on paper.. then make a dot on the top and bottom line at the halfway point of your oval or loop..

this loop represents what the string is doing inside your headrail.. and the dots represent the 2 lead ends of your verticle blinds (assuming its a split draw that meets in the center when closed).. these lead ends are attached to the string and travel with the cord loop..

if you visualize what would happen when you move one dot on your drawing you will notice the other dot moves in the opposite direction.. Thats exactly what happens inside your headrail..

the cord is attached to the lead ends by a knot or a screw..

one lead end will probably have a screw that bites down on the cord and the other will probably have two knots where each end of the cord meets and is tied off after its fished through a hole in the lead end mechanism..

each end of the headrail will have a pulley that the cord will go around and the excess cord will be pulled through your control end.. Excess string can be taken out by grabbing the knot closest to the control and pulling the string, then retie the knot and cut off the excess string..

how you open up the ends of your headrail to accomplish all this depends on the manufacturer but should be pretty self explanatory..

be sure not to tangle your string in the head rail

to know where to set your lead end with the screw that bites down on the cord, draw your string so the side thats functioning is stacked tight and closed and then manually push the opposite side to do the same.. After any slack is taken out of the string, this is where you want to clamp your lead end down on your string..

If you have a 1 way blind, you just have 1 lead end with both ends of the cord attached to it.. the idea is the same with less steps and worries..

do yourself a favor and take a buncha pictures of the workings of that thing with your digital camera before you take it apart..

good luck

Thanks for your response. I have a one way draw with a broken cord, but I will take your suggestion and take a photo first and try to follow along.
