A Rope Making Machine

As with all of my drawings: copy them ,Use them, share them, DO NOT SELL THEM! and please consider giving me a donation at the yellow “buy now” button… And Like and Follow my blog to see what I’m doing next.

so I turned these pictures (above) into these drawings (below)

I found pictures of this one on the internet, attempting to backtrack to the original poster got me stuck in a loop where the picture on a site went to another site and back to the first site etc etc… If anyone recognizes this, contact me and I’ll put your name on it.

you will quickly notice that the drive gear is bigger on mine than the original. the original looks to be 1:1, I drew this 2:1. if you want 1:1 contact me ad I’ll redraw this for you.

The front and back are identical but for the 2 extensions, I suspect the extensions are to brace this against posts or in a narrow doorway. but they also serve to capture the spacers that hold the face in place.

These spacers have to lock into/onto the back plate, hold the front plate in position without pinching the gears, or letting the face get to loose…

this is accomplished by simply pinning them into place.

I can envision several ways of making these, one is to turn the profile on a wood lathe and carve the posts. But you need to use your hardest wood for the posts, and carving lignum vitae is tough…

Another is to cut 2 pine or poplar disks a bit bigger than the 5″ Ø finish, draw the 4 1/2″ Ø ( R 2.25″) circle and drill holes for the posts you will make from some very hard wood, white oak, live oak, lignum vitae all are good choices. Then assemble the 12 posts, the center 1″ post, and 2 discs with glue and or pegs. then turn, shave or sand the discs down to the 5″ diameter. The hardest part of this part is the hook, it must have a hook to grab the yarns.

In use that little peg is used to secure the fiber for twisting… I can think of several ways to incorporate a hook instead… can you?

edit: not the angle specified in the above drawing… it is wrong!!! that angle is 45°… sorry

I think that the best way to make the big gear would be to make make a sandwich… the middle (filling) is hard white oak, live oak, lignum vitae etc.. pick one, that will have the teeth cut into it, glue up a pie of it, Using 1.25″ thick material, a R5.625″disc made up of 30° wedges with the wood grain running from center to rim all around. To layout the teeth, on good paper , draw a 4.5″ Ø circle and mark the center for a 1″ Ø hole, along the outer circle mark off every 1 3/16″. these marks locate where you will later drill 1/2″ Ø holes. From those marks you will make arcs to the left and right at a R 7/8″, these will be the faces of your teeth. (see sketch). Then you can adhere the paper to your wood for a very accurate layout. Now drill the 1/2″ holes, and the saw the teeth with a jigsaw or on your bandsaw. Split that line so there is less cleanup to do later. or cut on the “inside” of the line. Loose teeth rattle, not usually a problem , fat teeth jamb and have to be filed down…

Then your “Bread” can be any reasonably durable material that you have around , make 2 discs 8 3/16″ diameter with a center hole of 1″. and your toothpick to hold it together will be a hard 1″ dowel left long for the crank…
