Ok, ok. Even though you'll never see it when it's in use, I'll do a chamfered end and then have my machinist make me up a tool with one end elliptical and the other end a female chamfer to match the one on the part that I can use to put the O rings on.

Maybe a bit longer for balance and another O ring for stability.  It looks like it will wiggle around with a short stem and only one ring....

Ok, just got off the phone with my machinist.

 

Yesterday I sent him a number of different TRS jacks and their inside diameters varied from about 0.251 to 0.257. And one of them had a rather sharp edge at the input. He pointed out that using the O rings perhaps wouldn't be the best way to go given how much slop there is among jacks. So he came up with what I think is an even better idea. A split pin design.

If no one has any objections to this by the end of the day, this is what I'll pull the trigger on. Cost will be the same if not slightly less.

Looks good.

Ok. Just gave my machinist the thumb's up for his design.

Umm... Does anyone have any use for some O rings?

 

I just received delivery of the O rings I'd ordered from McMaster-Carr before the design changed to the split pin. biggrin.gif

Paint them silver and use them to weave yourself a chain mail shirt! biggrin.gif

...then again, there's the "cable fashion design" we discussed... very_evil_smiley.gif

Don't give me any ideas. biggrin.gif

 

Maybe I'll send 'em to Terry Border. He likes doing all sorts of weird things with ordinary stuff.

My machinist will be testing it on the several TRS jacks I sent him.

My machinist called yesterday, said he should be able to ship the plugs today. If that happens, I'll have them tomorrow.
