One of my favorite slide rules is the Charpentier Calculimètre. Something about circular slide rules makes understanding mantissa rollover easier, which helps a lot when I try to teach people.

This example dates from the 1910s, I believe.

Anyway, in this image I have the index at 3.14 which, you can see, approximately equals 22/7.

Close-up of a circular slide rule with numbered scales and a metal cursor. The outer and inner rings are nickel-plated and so appear silvery, while the middle ring is brass.

Spliced and tied my first soft shackle today.* Dyneema is a strange material to work with: apparently nearly as slippery as teflon so requires special knots, is really static so requires special knots or splicing, et cetera.

Anyway, for my application it’ll be just the ticket but I won’t give up on real cordage just yet.

*My person helped because I’m not very good at stuff.

Some aluminum-colored cordage spliced and bound in a loop. It has a decorative stopper knot in one end that serves as a stopper for the small loop at the other end. It’s resting on an old wooden cutting board.

Fedi, is there a power tool I can rent that I can feed wooden Venetian blind slats through one by one and have it sand both sides (edit: or even one side serially)? There are ~400 of them so I don’t want to even power sand them by hand one by one.

Edit: thicknesser = no, the slats are already the right thickness and I only want to remove the peeling varnish on them.

jointer = no, don't think this will work with slats that are only 3 mm thick, it'd probably take off too much, and it's optimized for edges rather than the top and bottom

drum sander = yes, maybe, but I don't want to own one (and a dust extractor) for a one-off job.

benchtop/handheld belt sander = suspect this is where I'm going to end up unless I have a woodworking friend in driving distance.

Thanks to all for educating me on the range of woodworking power tools for this kind of job.

Someone once said NextDoor is the social network for dogs if they could type. It’s always “what’s that noise?” and “who’s that stranger?” which is exactly what I imagine my dogs would text other neighborhood dogs.
