Why does it avoid torsional stress?
Because of the friction between battery and tube?

If the QTC is in the head then there is a compression and twisting motion being applied.
If it’s in the tail then it’s mostly just compression from the flat cell negative.
The cell positive is taking all the twisting force.

There have been various methods to protect the QTC like placing it between conductive plates, tape etc in head twisty applications.
I’ve found that method to give more flickering output, especially on lower pressures, the conductive surfaces oxidize etc.
QTC is fairly fragile and will split or wear out faster due to friction if you have it just making contact on the cell & head contact being compressed and twisted.

That’s what I think anyway.

You can see here how Fritz used three QTC pills between two brass plates to try to overcome some of these problems. I don’t know how successful it was as other parts were too damaged when I received this light.

This might be worth a shot for me at some point. Great resource here for QTC. I have gotten oddly fond of the 10180 lights, and they seem perfect for this.

So…has anyone ordered from mindsetsonline or zoflex already?
I consider doing so early next year, I spent too much in this one already.

Are you willing to resell some of it if you do?

The question is: is it worthwhile to make a GB?

I remember that shipping from mindsetsonline used to be $20+. I’ve had the idea of a GB in my head since then.
I have a feeling that the current price is not prohibitive – but still ordering more gives a nice per-item discount.

I could order more and resell if there’s interest in saving several bucks (note: untracked shipping is a little under $1.5 from my place). But there must be more people, for just one it’s more hassle than it’s worth.

So…should we create a new feeler thread or would it be OK to continue here?

This thread doesn’t have the right title.
It’s better to make a new thread.
