Tension Box Comb


Tension boxes can be fitted out with combs on their ends.  Combs help to keep individual threads in order as the warp is loaded onto the sectional beam.  This one came with the tension box.  It is actually a reed, since combs are open at the top.  But it will serve the same purpose and while a comb facilitates easy loading, it is important to have a top on it in case something makes the yarns jump and therefore become crossed.  A reed will serve this purpose just fine although it takes time to initially thread it.

This reed was covered in surface rust.  It was not pitted.  I tried using very fine emory cloth and steel wool, but it did not clean this reed very well…


A 4″ bronze wheel brush on my electric drill did a great job in cleaning it up…


This reed is a 10 dent reed that measures 8″ x 11 3/4″.  It has a total of 117 dents.  It is now smooth and ready for use…


Tension Box



A home-built tension box came with this loom.  Half inch oak plywood sides are joined by 3/4″ (i.d.) galvanized pipe.  The pipe is secured by driving in the nuts from 1/2″ bolts into the ends of the pipe and then secured to the plywood from the outside with 1/2″ bolts and washers (1/2″ nuts have a diametre slightly larger than 3/4″).  There are eight pipes on the top level and two on the lower level and mounts for reeds at either end.  It is well built.  Today I disassembled it and cleaned it, steel wooling the pipe, sanding all wood, and routing a finished edge onto the plywood.  Then I oiled it with linseed oil.  I will give some thought to what sort of legs I want on it.  I am very pleased with this result…
