My Heck Block for Warping

Here is my heck block that Jim Ahrens built and used.

This is the view of the whole assembly–the two poles that the heck block rides up and down on, the heck block and the reel itself. My ceiling is higher than the poles Jim made so a board was put in to anchor the poles to.


Heck Block for Warping Reels

Jennifer asks for a quick way to warp multiple threads at a time. The most available method for weavers today is to use a paddle. I have a chapter on using various types in my Book #1, “Winding a Warp & Using a Paddle.”

Jim Ahrens’ warping mill which I use in my studio has a heck block–a marvelous (and old) mechanism that he made. I am warping 10 ends at once while  making a thread-by-thread cross (lease).

This is from Page 16 of my Book #1 ,” Winding a Warp & Using a Paddle.” I don’t know if anyone makes them now, AVL did for awhile. You might look them up in old weaving books from Europe.

The heck is a mechanical way to spread your warp at precisely spaced intervals along the frame of a warping reel. It moves up and down on a vertical support that stands next to the reel, or if the reel is horizontal, it moves back and forth on a support alongside the reel. The central
support of the reel extends beyond the reel and turns with it: a cord wound around this support is attached by a pulley to the heck.
As you turn the reel to measure out your warp, the cord unwinds, and the heck block moves along the length of the reel. As you turn the reel for the return trip, the cord winds back round the pipe, drawing the heck back along its support. Multiple warp ends, which are threaded
into a leasing and tensioning device on the heck block, are carried with the heck
and so are laid down on the reel automatically.


Counting string isn’t in the new book!

I discovered that a student needed to use a counting string when making the warp for her very first project! I’ve put a note to myself to add it when the book is reprinted. See the tip: Counting String.
