What bike tool is this thread?

Okay I went to the bike swap in Boulder, CO at a kool bike shop I like (Fat Kitty Cycles). I came home with some bike tools that I just didn't know what they were.

Can anyone help identify these mystery bike tools and explain what and how they are used?

Skip the identified tools and scroll down to the current mystery tool. Right now this is the current tool:

This mystery tool has been identified. Not a bike tool but a tin crimping tool for heating and A/C ductwork.

OP:

IMG_6121.jpg

IMG_6123.jpg

IMG_6122.jpg

First up it kind of looks like slip joint pliers except someone forgot the slip joint adjuster.

Markings say "Silver Streak" and each handle is marked "alloy steel" in case anyone thought it was made of pure elemental iron.

Guesses? What is it and how do you use it?

My first guess would be, not a bike tool, but something for crimping the end of a stovepipe, so that one piece could be inserted into the next one.

Looks more like a duct crimping plier than a bike tool.

My first thought was a "Z" spoke crimping tool, but have to agree it looks more like it's for working sheet metal.

They look like old-timey Z-bend pliers.

Dr. I may have it, but there appears to be two levels of "z bend pliers". One bends control rods for model airplanes.

Another apparently can be used to make spokes. This tool for spokes looks a bit more beefy than the OP's picture:

I think you guys are right that they are a duct crimping tool. Definitely wouldn't make a z-bend in a 14g spoke, it could only barely manage the first bend. That's actually what I thought they were but they just aren't. They make near perfect crimps in tin, duct tool it is.

For those that don't know you need a z-bend tool to problem solve a classic hub like a Sansin (also branded Suntour or Specialized) Hi-E or Mavic that you want to build into a wheel, when someone left the freewheel on and cut the spokes. You need a built wheel to get the freewheel off, and you can't get new spokes in because the freewheel is blocking the way. Using z-bend drive side spokes allows you to build up the wheel (on say a 559 hoop) to get the freewheel off to actually build your desired wheel. You build a smaller wheel like 559 because you cut off the J-bend and then you can cut and size down 635/630/622 wheels.

A great way to get hubs that were better quality than Campy cheap. I still need one now still, after this didn't turn into one at midnight. Some day I'll break down and buy the Wheel Fanatayk but I prefer to hunt for my tools via swaps/eBay.

This mystery tool has been identified. Not a bicycle tool but automotive battery terminal clamp expanding tool.

OP:

I think these are either to expand handlebar ends to take barcons/barends or a similar tool to the rare Park BCE-1 tool to round brake lever clamps.

Thoughts?

I think the second one is an automotive tool used to expand battery terminal clamps. Here's a similar one: https://www.amazon.com/Lisle-55410-B.../dp/B005ADY9PY

It is not a duct crimping tool.

Ha, that's pretty much it. Okay, battery terminal clamp spreader, it is. Well the first two mystery bike tools aren't even bike tools. For sure most of the rest are, I know what most are (even what brand) and I'll post the "for sure" ones last.

I have two of these. In my mind they are "add-ons" to an ancient work stand. If you look at vintage Cinelli truing stands or work stands they are pretty crude. Same with a vintage Campagnolo stand.

These are overbuilt and cast the way a stand alone Hozan truing stand is, but they feel to me like they would sit on a work stand to check theateral true of the wheel. The wingnuts remind me of the brass wingnut on my Var adjustable pin spanner, only these are definitely not brass.

By turning the wingnut you can back out the "feeler" to different widths. The feeler sits on a spring so it can deflect, or give, if the wheel were to wobble to either side.

There is a slot on one side of the rounded handle, presumably to orient correctly into the stand that holds the hub?

I have two. One is missing the feeler, spring, and wingnut on one side.

Those look like universal joint shafts -- possibly from a passenger car or small tractor. I think they've been repurposed as truing aides.

I can't confirm from experience what they are, but it looks like they could function as the 'feelers' on a truing stand, similar to the spring-loaded arms on a Park Tool TS-2.

The slot would not only ensure the piece is oriented straight, but could give a good surface for a grub screw. That way, you could set the feeler at a specific height to accommodate different wheel sizes.

My first thought was that they're oarlocks adapted to be some sort of wheel truing reference. There are two...oarlocks come in sets of two.

Indicator assembly for ELDI wheel truing stand

It appears that you have the indicator assemblies from two ELDI wheel truing stands.

I have attached an image from "Worthpoint" so you can see a complete stand.

The design is simple and effective. The stand is heavy enough to remain steady when in use.

cyclophilia is the winner! cyclophilia how did you know that? That's an obscure truing stand!

Definitely the indicator/feeler assemblies from a German cast iron ELDI truing stand.

Another pic showing the parts I have more clearly. You can clearly see the wingnuts and Front groove. The oar lock crowd +1 point for creativity -10 for just being wrong.

If there are any more wacky old tools in this collection, we're going to need some scale in the pictures -- beer vessels would be preferred. Euro banknotes or pressfit bottom brackets should be avoided.
