What is it? CXCIV

I found your top posting to be thoughtless, ill-founded and hard to fix.

Todd was displaying something called humour. Irony to be precise. Look it up. And then look up bottom-posting and why it's better.

A) Whoooosh B) I tend to find people who top post to be unobservant, thoughtless and destined for the kill file.

Depends, if you don't/can't/won't trim, then I much prefer you top post. Otherwise, when in Rome ....

What you are calling fingers I was calling support arms.

O.K. I *guess* that it could be used that way -- but I would have designed it with something as part of the device to control the tilt of the fingers in the basic linkage, not depending on a cavity which may or may not be available in the piston.

And there are too many likely lumps inside the piston to really allow it to work reliably. A piston is not typically as empty as a coffee can. There are the bosses which carry the wrist pin bearings and keep the connecting rod centered.

But unnecessarily complicated to use.

I still think that it serves some other function.

Enjoy, DoN.

According to Alexander Thesoso :

Thanks -- but this was a different Don (no upper case 'N') -- and it sounds as though he was posting from experience with the device, while I was simply guessing based on the apparent behavior and materials

-- plus the 8-2/0 marking.

Enjoy, DoN.
