Re: Double countermarch
Hi Everyone and Liz M
The HD Designs Rug Loom designed by Peter Collingwood. Is an ok loom. The loom has 4 shafts. In order to do the one-time tie-up Peter designed you will need not 6 but 8 treadles. The sheds open in jack rabbit fasion, weaver using both feet, to open a shed. We all know when we open the shed on a countermarch loom the weaver can only depress 1 treadle, if we try to depress 2 treadles down the loom will lock and no shed will open. This is not the case in using the tie up Peter designed. The tie up works like a skeleton tie-up for countermarch. the weaver will have all 4 shaft tie-ups.

Subject: Re: [weavetech] Double countermarch
Ive just learned that this setup is used on the HD rug loom, designed by Collingwood…tho he wrote this piece that I was referring to in the Quarterly Journal in Britain in 1957, long before he was working with HD on the loom. What a guy.
I also realized that if I put all lams side by side on one rod, then I can’t use Kati Meek’s ingenious tieup system, using only half of the cords. Mine is a Toika and has the upper lams corded to the bottom shaft bar but the lower lams corded to the jacks or coupers. I guess I’m not sure on your explanation of the lower lams on your Cyrus. Would you be willing to send me a photo of what you’re describing?
Thanks so much for your response. Looms Mechanics are my thing.😊
