Make a tuner?

[Ramblerman]

I like the idea of a tuner and I think I saw something like this will end up being a long time ago...and having found a ridiculously cheap micrometer barrel on fleabay...I'm gonna try and make one. It will clamp to the muzzle and hang there.

I'm thinking a .875" bore and a corresponding register on the end of a HV contour barrel. The micrometer barrel will actually be behind the muzzle to keep oal of the rifle reasonable with it installed.

Got the billets cut this am...more to follow.

A bit of progress today...

Ready for a barrel with a register on it...I better get on that...

Weight is now 8.9 oz...from 11.9 in it's "wrought state"...I was shooting for 8ish... we'll call it ready to test?

OK, I give up. How is this thing supposed to work?

A weight, in this case a micrometer head or barrel, runs in and out parallel to the bore like any other barrel tuner. I'm no Scientologist, , but redistributing mass to affect harmonics.

 

[GenePoole]

Oh, OK, now I kinda get it. I thought the micrometer pushed against something else.

How much does the thimble on the mic weigh? Thats the only part that moves right and thats the part that matters? Your tuner may be different but i need about 4oz to move to work for me on a br barrel

That was a good question Dusty, so I just weighed it...2.6oz...I could add weight to the barrel/stem eventually...but I do have an inch of travel too. Think I'll try it first, but that's something to keep in mind, thanks.

Barrel cut and we have a tuner!

 

[Dusty Stevens]

Great job!

 

[Ramblerman]

Great job!

Thanks Dusty

That is the same design that Dwight Scott came up with. Dick Wright had an article about it in PS magazine. His only used a threaded rod. It would surely move the POI.

That was many years ago. It did work!

That's probably where I got the inspiration...and with the 2.5 braincells I have left that Irish whiskey didn't kill...how I came to this

How are you locking the micrometer once you find the sweet spot?

 

[Ramblerman]

The hole is fitted to the stem...and a bonus was discovered once clamped onto the barrel...the micrometer stem now has even more friction...plenty I believe. Ready to test!
