Kimber muzzle brake timing help?

[coues32]

Picked up a brake from Nathan at muzzlebrakes and more. For subalpine in 300 wsm
Has anyone found shims for timing brakes for a kimber?

How far and which way out of index are you?

 

[coues32]

Not sure, will have to check

My Christensen Arms MPR used a crush washer for the indexing. Makes it pretty easy to adjust it to where you need it.

I looked at the same break but threads are thin on light kimber barrel and just went with standard kimber brake on my .280 ai. Have an extra as well if interested.

It looks like you can burn about. 009" and it'll time. That's how I'd do it....then no washer to look at.

Take off the brake? Tools needed?
1st brake I've had to put on.

If you have a flat surface that you can place a piece of 400 grit paper on, you can burn it back.

I'm assuming that you torqued the brake tight. You'll get another 1/8th turn or so before it is tight.

You can figure exactly how much to take off mathematically. 1 inch ÷ tpi gives you how far the brake travels in a full turn. Divide that by the amount you want it to travel.....and you're there. Just make sure you're counting when it's tight.

Can you explain this “burn it back”?

416 stainless sands down pretty easily. Why can’t you just slowly take a little bit at a time off the back end of the brake, checking often as you sand, until you have it timed correctly. Should only take a few minutes by hand and using a block with some fine sandpaper. I’ve timed brakes that way without issue, just make sure that you don’t take too much off at a time between checks.
I did this one that way on my .300wsm Kimber Montana.

Just like Trout bum said, sand it down.

It's actually about .021" off since it's upside down and short. Flat sanding the back of a brake for a few thou is generally OK but when it's .015-.020" or more it's pretty easy to sand it crooked especially with a brake that has very thin matting surfaces. It's just too easy to tip it when your sanding.

Just take your time, it’s really not as hard as it sounds.

I bet I have more experience with muzzle brakes then anyone else on this site. I've seen about every screw up a person can do with one. There is a reason I know so much about the timing of that particular brake

How long is that brake? The pics make it look 4 or 5 inches long.
Been wanting a brake for my Kimber Montana 280ai and something better for my fierce 300wm. Plan on giving this guy a call as soon as he gets back from his hunt. Which actually should be today.

Thanks for all the help, I think am the right track. Be a while b4 can get it taken care of due to work.

Not sure, will post if can grab a measurement on it.

Nsthan has been great to deal with.
I'm sure he can get you set up for both.
