Can't afford a headspace gage? Make it

[MDSpencer]

Also it's easier to Grind and Accuracy is everything in our world, I'm not into close enough for the girls I date

I was quoted an absurd price for a headspace gage from JGS once when I needed a 6.5 MS reamer for a greek surplus rifle I want to build into a custom. The reamer was something like $200, and the gage was quoted at close to the same, it was either $160 or $180. I figured I'd come up with some other way than pay that much for a go gage. I even asked "Are you certain that's the price????" and was told an emphatic YES....

 

[MDSpencer]

I'm not really complaining. Making the reamer is beyond most all of us.

Cost of things is what it is. An others are surprised that something they paid $60 for twenty years back has jumped.
Back to me..
What I should have done on this .220 Russian is totally made it on the lathe.
Hard turned and everything

A good friend of mine and retired machinist from Caterpillar has a way of measuring head space with a ball bearing. Not sure how he does it but he has forgot 10X what I will ever know about this stuff, so I am sure he is getting the right measurement.

Why not rent one?

That won't work it is too simple.

How much do you want me to pay. I work a full time job. Tool and die type work. So I might not get to job for a week or two. Rent sure. If you have the time. I don't have the time on my hands like some.

Nice work.

I use datums, I have a few grinders that grind pilots, they grind angles and they grind tappers and they butt cut.

How do you grind a "tapper".

That would be using a gage with a radius, I am the fan of using datums with an unfriendly sharp edge.

@JRS Hmm, brings back a year and three month old post for what?

Mr Guppy,

Butch,
You true the wheel to the angle you want to grind. They make a special fixture to grind pretty much any angle or radius that you need. The angle is usually roughed in on the lathe, and finish ground. Fun stuff.

Paul, I know how to grind a taper, but not a "tapper".

Alan warner had a couple posts here on how to do that some time ago.

 

[MDSpencer]

Correct. A little math goes a long ways

That thread is here:

I have since made a spread sheet from my calculations and use it for odd-ball headspace measurements, or to confirm dimensions of a gauge of unknown origin.
