Darn! I just typed a great post, and when I went to preview, it disappeared! Trying again.
So after my last thread and all the great info I gleaned, I have a question. It seems to me that there's a logical and relatively easy re-design possibility for the RH loom.
Now, if I want to get, for instance 20 EPI, I have to have 2 10-dent rigid heddles. Instead, why not this type of alternative?
Make a wooden frame, the exact dimensions of the current frame of the rigid heddle itself. Add an upright on each end. Leave out the heddle itself. Instead, put on a whole lot of Texsolv heddles. (I suppose you could use metal heddles, but Texsolv is my heddle of choice.) Thread 1 yarn through the Texsolv hole, the next through nothing (as if it were a floating selvedge on a multiple-heddle loom). Now add a semi-standard reed/beater combo. My preference would be a 12dent, because I feel they provide the greatest flexibility. Now my RH loom can do almost any sett I like.
It can't be as easy in real life as it is in my mind, or someone would have done it long ago. So where's the flaw in my thinking?
If there isn't one and you create & market the device, share the profits with me. :-)
