What is It?

Adjustable leg stand for a Gorilla cage....

Another trip hazard that needs tidying-up before someone goes base-over-apex. Someone is getting careless over basic housekeeping.

Don't say this has been found on Pluto?

how about under Ceres white spots?

It must be a table leg leveler to be used after sawing a little bit of each leg to try to get it level. Assuming, of course, that there are any legs left.....

The little lightning bolts makes me think it has something to do with a tazzer....or it could be something to do with electric fence installation.....

I give up!

Just another useless invention nobody really needs....but will probably make some guy rich....

A cork pusher (as opposite to cork puller)...

Years ago I had a little hobby vise with a suction base. It also came with a clamp that looked just about like this to more firmly clamp the vise to a table.

This clamp is orange and seems to have a cartoon character of a gorilla on it.

lets say you might find one in a motorcycle shop

With the lower part being larger diameter, I'd say that the handle..... you cut it off the picture..... intentional maybe?

the smaller round rubber do-dad pointing up looks like its the working end.

Some type of inserter or extractor or something.

nope

ok... what's the reason? what are they trying to accomplish.....

^{Don't I get partial credit.... I nailed the handle and working end.}

its a tool to set proper chain tension

Ok,... still not following though. so, you tension it and after you release the tool.... wa la... proper chain tension.....?????....

That's about the size of it.

thanks doorman.... and fredski.... I didn't realize the need for a tool for that.

A 'GA'?... for giving the right answer to your own question....wow!

The chains I use have a derailleur that adjusts the tension as I change gears.

motorcycles are different I knowme after a Laughlin run no chain, Kevlar belt

Newbie in training

Yes, that's not how I'd do it... But.... It's being a long time since I rode bike....so.... I could be considered a newbie,.... So

I'd be offended if it wasn't true... But since I didn't know it's even existed.... Or even since that I do know now,....I'd never use it.

Chain Monkey.

...Another monkeys job lost to progress.

I wonder how it got the name?

A LynDoor CR4 Arm-Bender ®!

Wow, I've been riding motorcycles and adjusting chains for 37 years. I never knew I needed that.

But my Buell has a belt and a spring loaded tensioner so no more oil fling on the rear wheel. Still have a bevy of dirt bikes with roller chains.

Yes... And now you need that.... You can't live without that..... Right?..... RIGHT?.... Where'd you go?.... I'm talking to you.... Hey, who shut out the lights?

Interesting post, Fredski! I wonder if such a device could be used to check tension on vee belts, and timing belts?

This is a belt tensioner.

A worthy candidate for a "What is it".

We got one with every belt driven centrifugal we bought, in a past life.

One thing to note when adjusting motorcycle chains, is to rotate the rear wheel off the ground and just 'watch' the chain. Sometimes the rear sprocket is not concentric and the chain tension will increase and decrease as it rotates. (Also you can spot any links that might be binding.) Set the minimum tension (free-play, usually about 3/4 inch to 1 inch) when it's at its tightest so you don't excessively stretch your chain. I usually get about 20,000 miles out of my street chains with a modest amount of care. A slightly 'loose' chain does far less damage than a slightly 'tight' chain. Obviously, a grossly loose chain can be a significant safety hazard.

we have 2 conversations here, you are correct about motorcycles, a bicycle chain isn't about chain life

Very true.
