This demonstration shows a 4 x 2 setup. Four (4) strands of two (2) yarns each.
The machine is set up with dark cotton yarn in preparation for creating a short segment of twisted cotton cordage.
Once the yarns are placed the lengths are equalized so all four pairs are at the same initial tension. The pairs are looped around all the hooks so they can be adjusted easily.
Then the gang crank is turned several hundred times with a few pauses to keep the twisted pairs separated.
During the initial twist the yarn's length is naturally reduced by the twisting action. The traveler takes up the slack with a counterweight holding tension on the yarn as it is twisted.
The yarn pairs are now tightly twisted (+300 turns) together and the rope is ready to be made.
The initial twist has been completed and we are ready to wind.
The ball shaped object on the left is a separator made from a large cork (taken from a bottle of tequila) with a pattern of guide grooves. Each of the four yarns runs in it's own groove as the traveller takes up the wind.
The traveller is riding in the white track (borrowed from a bi-fold door) as the counterweight holds tension on the system.
The separator is disengaged and the rope is almost complete. A piece of tape will be applied to secure the four parts and prevent unraveling.
See what cool stuff this machine can produce in the kits+supplies section of the ETSY shop.
