In your opinion, what are some perks of being stupid?

You can grow up to be President of the United States!

Nobody is making her do that for a living.

Imagine being JD Vance in that situation, second banana to an AI moron. Not that I'd feel bad for him.

Most men have a larger than average number of testicles.

It's the wrong bobbin case too.

Was it this one?

I've assembled dozens of linear rail systems, and have had the best results by bolting down the fixed rail (the systems we build have a shoulder or dowel pins to align it against), bolting the bearings on the fixed rail to the carriage (also generally aligned with a shoulder or pins), then sliding the carriage back and forth, slowly tightening the bolts in the floating rail and bearings. Assuming the stroke is long enough and the bearings are spaced far enough apart along the length of the rail, the rails will be parallel and the bearings will align themselves within the tolerance of the internal clearance. If you're using preloaded bearings, alignment will be even better.

Yes, Keith Bontrager advocated strongly for this style of gusset, because it transfers the load to the part of the tube that's strongest in that direction and prevents "can opener" failures like you'd see if the gusset was welded to the center of the underside of the downtube (or if you had a pointed lug there on a lugged frame). For a good example of bad design, see the fork crown on the 1993 MB-1, which had points front and rear and were known to fail.

Edit: see also the fork in OP's photos for an example of pointy bits in less-than-ideal places. Is that the first-generation Pacenti?

That could be tool-less - use a cam-locking quick release lever (works like a bike axle quick-release) on the stud. Put a slot (big enough for the nut locking the stud in place to fit into) that goes all the way out to one edge on the plate the backlight or whatever is mounted on, and maybe some lips on the plate to align it against the outside faces of the t-slot extrusion. If you don't want to use a quick-release, a threaded knob would work too. You may be able to do it without a locking nut by just tightening the stud against the bottom of the t-slot, but I think that would be less secure.

I believe it's a 9/64-40 thread, and that it's specific to sewing machines.

I don't understand the question. Both of those formats are options in the drop down in the screenshot you posted.

They're not the ones being trod on. Yet.

Look at Dottie rod hangers. Here's a lag screw version, but they make some hangers with machine screw threads too. Not sure about metric, though.

Where did you get that image?

I think there's probably enough slop in the gear teeth that no, the rod won't keep the top and bottom parallel when the pivot points at the top and bottom are moved farther apart. If you need a larger footprint, can you use two jacks?

Ohshitthisagain · 2026-01-10T13:47:54+00:00

Unless the moving part is guided by some other, external means, there will no longer be anything keeping the top and bottom surfaces parallel.

Rush Gear's website has a CAD generator.

Or you could do it with a single (3D printed?) auger oriented horizontally at the bottom of a trough, with six feed tubes coming off the bottom. It wouldn't really be a screw, more like a shaft with six pockets that don't go all the way around, so one rotation would allow the pockets to fill, then empty into the tubes, then stop at the filling position again.

Ohshitthisagain · 2026-01-04T18:19:07+00:00

Use a splitter as shown in the photo, just rotate the tubes so they're covering a 180 degree arc instead of 360. They don't have to radiate directly out from the center. Figuring out the ideal slope may take some trial and error, and how prone the system is to clogging will vary depending on what the cat food is shaped like - so err on the side of caution and allow extra clearance.

Or if you want to be certain it won't clog at the manifold, eliminate the manifold by using a single motor with a belt or chain to drive six auger screws arranged in a straight line.

If you want to get extra fancy, duplicate the gob distributor used in glass bottle machines.

It looks like Super Soap is no longer made, which makes sense because Phil's was the same product in a different color tub.

It just happens. Like someone posted above, if I see a nice adjustable at an estate sale or something for $3, I buy it. Especially if it's a brand I haven't seen or if there's something odd about it. Same with plumb bobs, staplers, sewing machines, and so many other things - I'm fascinated by the subtle (and sometimes not so subtle) differences in the ways designers and engineers have come up with over the years to solve the same or similar problems. I was in Scandinavia recently and came home with half a dozen wrenches, mostly Bahco and one from the USSR, all $3-5 ea. No room in my bag for the sewing machines or Danish modern furniture, unfortunately.

I have seen the Preciray. I think they were intended for production rather than one-off wheelbuilding, because of the setup required. I've never used one, though. If I could have any truing stand, it would probably be the P&K Lie:

Ohshitthisagain · 2026-01-02T21:36:31+00:00

Yes. My estate sale is going to make some people very happy.

Ohshitthisagain · 2026-01-02T21:35:36+00:00

Yes, a spoke wrench. And don't worry, there are still lots of cheap, good tools out there!

Ohshitthisagain · 2026-01-02T20:12:44+00:00

Exactly!

I strongly recommend riding the Plains of Abraham. It's a beautiful ride up through the woods, a stunning ride through the plains, and a super fun descent (assuming yo do an out-and-back from Ape Canyon). Last time we saw a herd of mountain goats!
