Custom Chamber Reamer for Go/ No Go gauges!

[panzermk2]

Custom Chamber Reamer! It will be here in a day or so. Then it's to the Bridgeport to make go/no go gauges.

I don't know what the price is going to be yet. I did not get the carbide cutter, I did not know if there would be enough demand to justify the cost, just the standard cutter that has a life expectancy of 100 chambers.

So the first run will be 100 gauges.

We will be taking pre-orders at an intro price. My target is price is $35.00 with the intro price being lower.

Sorry to ask a stupid question, but why would somebody other than a manufacturer need a chamber reamer? Maybe I don't understand what it is, I think it is a specific type of fluted reamer used by gunsmiths and firearms manufacturers to cut the chamber of a handgun, rifle, or shotgun. Why would a gun owner need one of these?

No one makes a go/no go gauge for reloading the 5.7 round yet. There are universal 'blanks' that you could drill & ream on your own but some people aren't sure just how to do that correctly.

Because I am and I needed it to make the gauges.

Unless your doing that work OR making case gauges. Also because this round has a unique shoulder and is very small the cutter is specialized.

I was letting everyone know I have finally gotten my reamer. Custom reamer delivery times run from 8 to 12 weeks. Then the steel for the gauges has to be ordered and then the gauges produced.

Can we get an update on the Go/No Go gauges? Were they completed on Dec. 4 as originally planned?
Thanks

Jay,

First of all, I mean no disrespect here !

I’m just curious as to how this “go/no go” gage works.

Unless things have changed dramatically, a go/no go gage only works on one dim at a time.

For the purposes of the “Go” gage goes, one could easily make a gage where any specific cartridge would go. In that, with the very nature of a shouldered cartridge, a ‘go’ situation is easy.

For the purposes of the ‘no go’ situation, in the ‘no go’ situation, just WHERE is the ‘no go’ gage basing it’s decision on a case of multiple dims. Case length, neck dia, shoulder position and or shoulder angle, main case diameter, or some other dim????? If the case doesn’t go, what dim do I look at that is the problem?

From the info so far, in a no go situation, the reader/loader does not know just what dim is out of tolerance.

Now I can easily understand a gage that measures each dim individually, and in that, the ‘no go’ would need to be multi cavity or multiple gages.

Please feel free to educate me where I am wrong.

Later today I am driving down to see my machinist to see what the hold up is.


What the gauge is a version of the chamber in your barrel. It is to minimum specs. In this case CIP spec. I ordered a custom chamber reamer. Basically think of it as a match grade chambered barrel. If the round has an issue it will not fit correctly in the case gauge.

You can use it in many ways.

First when you are setting up your sizing die. Verifying that your sized case fits into the gauge.
Then again with the round fully loaded you can check the complete round. Makes sure you did not seat the bullet to much and put a small buckle in the shoulder a common mistake with the 5.7x28.

If the bullet sticks up above the gauge you have an issue. There are tricks to see what the problem is also. Take the offending round and coat it in die chem or sharpie marker. Push it in until it stops. Then slide it out and look for missing marker. This tells you what to look for. Also you can spin the case a few times, you may have to repeat

I'm curious are these shipping?

[panzermk2]

Still waiting on the first production batch to clear inspection. The cutting is taking a great deal longer then the maker of the cutter claimed it would cut at.

Nevermind, I totally missed the point of the thread. I thought you were making reamers and go/no go gauges for people building 5.7 from 224 barrel blanks. My bad
