    Reliable DIY power ascender

    Yes. That said, it could also be nice if a person could buy a well built and readily maintainable electric power ascender for a reasonable market price from a supplies store. True, there is not really that much more to it than there is to a well-made battery powered drill, mostly a different...

    Reliable DIY power ascender

    Thanks for your post. I am still working on the "system" part of my climbing (I go from single to double -- depending on who knows what. In my lost past I have gone solo up sailboat masts, and the usual way for that is actually triple (first hoist a block w/ becket on a halyard, then pull 1/3d...

    Reliable DIY power ascender

    I'm just getting started on a Rollgliss 550 (five fifty) project, Have read this whole thread in an effort to learn everything I might from all of the experience you all have. My thoughts so far -- posted here for your criticisms (and amusement) are: -- Midline attachable is too important to...

    Documenting my hand-sewn eye process

    Agreed as to heat, but polyester and nylon burn just as readily. Can polyester burn? Synthetics (Nylon/Polyester/Acrylic): Ignites and burns quickly and can continue to burn after a flame is removed—exercise caution. Fiber may shrink from the flame,

    Documenting my hand-sewn eye process

    Dyneema can be cut. X-acto knife w/ brand new blade. Pair of genuine Wiss big size canvassmaker's scissors. Or burn using a Weller gun with a flat blade end. (A person probably should have a flat blade hot tool to do this kind of work anyway -- usually cheap ($6-8) at your local 2d hand tool...

    Documenting my hand-sewn eye process

    - Then there is the idea of several different kinds of "headroom." -- break test "headroom" ... If a smaple of the rope breaks when pulled on at 6,000 lbs, assuming the rope I'm using isn't damaged compared to the sample, I can put 2,000 on it without going crazy with fear. -- calculated...

    Documenting my hand-sewn eye process

    Semi-random notes from a chance to do a little reading of posts.... - The move to make hand work be entirely like machine work is not in all cases necessarily a good one in this context. That is to say that there are conditions in which a certain irregularity is a benefit. It is my view, for...

    Documenting my hand-sewn eye process

    A message landed in my e-mail inbox that came from this buzzboard thread, and I had a few (random-ish) thoughts of my own, and reply. I have wasted a bit of my life bouncing up and down on the ocean in sailboats, so I have some experience with salt, sun, corrosion, ropes, uv degradation. I...

    Documenting my hand-sewn eye process

    These may or may not help, but they show a (not especially tight) tight eye in a piece of (not very high quality) 8mm. In the first the basic result (before covering). Then, next pic, the initial "basting zig" is white and may be hard to see, and the 300 lb dyneema is begun. (Stitching is...

    Documenting my hand-sewn eye process

    For whatever it might be worth, I have been sewing some tight eyes, and I have a slightly different, but perhaps complementary, approach... -- I use about a 6 times the rope diameter sew length. (It is a diminishing function, and the "official" number is five times....) -- I make an eye that...

    request feedback on rigging device design and build

    For whatever it might be worth, I have built one of these (using a sailboat foresail sheet winch, etc.). The winch is mounted on a plate that has steel pins to hold it into a frame (the frame is steel but has wood pads on the back to try to be nice as possible to the tree bark). As part of the...
