Is there a way to reduce extension wobble?

I have a bunch of 1/4" drv regular extensions, if I connect two or more there is considerable wobble. Is there a way to reduce or eliminate such wobble?

I think, maybe using o rings on each joint, to reduce the play, but I doubt it will work.

I epoxy a couple together clamp them in a Bessey K-body clamp to make sure that they are dead straight let it dry and now I have a permanent long 1/4 drive extension that doesn't wobble. Works for me.

Spiral wrapping the joints tightly with several layers of electrical tape will often help noticeably.

A single long extension is ideal, but even if you buy yourself a really long extension you will still probably have some wobble. You likely won't notice the wobble if you are using it by hand, but you will notice the wobble if you are using a power tool to spin the extension. Very few brands seem to be able to make long 1/4" drive extensions without at least some bow in them (usually a result of the heat treatment process). I think I've had to carefully straighten every 1/4" square drive extension and 1/4" hex power drive extension I own that's over about 6" long. It is what it is.

I've been buying the Tekton longer extensions to compliment my SK's. I roll them across my table saw and they seem straight upon arrival.

bit of stiff wire as a spline and some elec tape should do you in a scenario where need hold it in a straight line .

adding shim in drive squares may work too (cut up some old feeler blades)

Just buy a set of extensions in each drive size out to 24". Probably the least glamorous tool purchase one can make.... but it's well worth it down the road.

Agreed. Sometimes you still need to combine extensions, of course.

The bigger problem is that the joints want to fall apart as you're extracting your super-long mashup from the bowels of whatever you're working on. 1/4" drive stuff doesn't have room for strong detent ball springs, so a few wraps of tape help a lot with this.

Linking extensions to get to hard-to-reach fasteners is a mark of true talent. I've done it before, because I was too lazy efficient to remove a wheel to get to a spark plug.
Or it's a necessity. Torquing the thrust mounts on an F-16 takes almost 6' of extension to get to the bolts. Torque value is several hundred pound-feet....

Thank you!

The best option seems to be buying longer extensions. The next best would be using tape, but that would make them sticky...

Is there any noticeable difference in wobble when comparing inexpensive and expensive extensions?

I'm not clear on why wobble is a problem. Most of my extensions are Snap-On so they may have less wobble than others but I have never even thought about how much they have, let alone, run into a situation where I thought I needed to reduce it.

It's the way they are and an intentional flaw to boost sales. If you have a 3", 6", and 9" extensions that work together perfectly, there wouldn't be a reason to buy an 18".

Consider a locking extension. If you need to use an extra-long extension, odds are it's because access is minimal. In that scenario, it will be extra annoying when that 10mm socket falls off deep in your engine bay.

This set looks pretty compelling. ~$29 from Home Depot.

I have different ones from Apex and Westward, but I don't think you'll find those easy in the USA (well, the Apex ones I have are Mastercraft-branded and they appear all-but identical to Gearwrench, but they're more expensive under that label; the Westward ones were on clearance so availability is dubious).

You win Garage Journal. Very cool.
Ryan: Here's what it looks like without the engine....The thrust pins, aka "coke bottles" are at 3 and 9 o'clock. Whom ever is torquing the 4 bolts on the mounts, has the torque wrench just inboard, about where the speed brakes, aka "duck bills" split. You can see the right pair open a little bit. Now imagine, that the engine fills that bay to the frames, with about 4" max clearance, until the end fairing. That fairing, aka "the do-nut" has less than an inch clearance from the engine when installed. We play in tight holes sometimes!

That looks uncomfortable and interesting.

If using a bit socket, the wobble makes it harder to align, increases the possibility of cam-out(please forgive me if it is the wrong term) and increases hand fatigue, due to having to fight against the movement generated every quarter turn. Especially noticeable while using a spinner handle. To be fair, I know that I can get a really long screwdriver, or a long hex bit holder, but extending the usability of a tool is a good thing. I will do as you guys said, and get longer extensions.

That is such a neat image! Thanks!

As a kid in the 1980's, I was just fascinated with the F-16.... until I caught the warbird bug. ;)

That looks like a very tight fit indeed!
