Probably the hardest chamber I've done. 300 WSM with a long freebore. Had to keep wax paper around the top of the body for every cut or it would get squirrely. In the end it sure turned out nice and I'm glad Dave turned us on to taking photos like this.

Funny I just did 2 300 WSM barrels. Wax paper was used frequently.

Good to know it's not just me

Nice work

 

[ORjeff]

Having only chambered one barrel I still have lots to learn, what's the wax paper for?

 

[Sniperhandle]

To stop the chatter, Uh I mean wipe the flutes off! Just kidding, It stops the chatter.

It keeps the reamer centered , but will cut slightly oversized, while the 6 flute reamer gets deflected from the 5R flutes. Several multi-page threads here about 5R/Chambering in general. Happy to discuss privately.

I had trouble with a brand new 300prc Mason reamer and a carbon proof barrel chattered almost the whole way that was the first one for me in 100 barrels boy does it sux too

Did you contact Manson about the issue?

Cool picture

 

[DaveTooley]

The picture sums up just about everything that's important in a chamber. Concentric, freebore sufficiently large enough to clean up the lands. If the throat looks like that then everything behind it is also correct. You can't get one without the other.
Using a watchmakers 3.5X or 4X loupe will let you see the surface finish on the leade. I've consulted with several manufacturers and I always leave a loupe with the guy doing the work. I have another company coming in next week and I have two loupes waiting for him. They have different focal lengths. One for SA rounds and one for LA rounds.

 

[LVLAaron]

I bought the loupes you (or someone) shared previously. I can't get pictures through them with the new iphones though- they have so many lenses you can't easily control which one it's using.

I'm sure the chambering job is fine but I really like the photo. Well done!

Thanks for the info, I have much to learn. My mentor told me to stay away from 5R because of the chatter problem. Seems like someone needs to make 5 fluted reamers.

Looks like the definition of a "rabbit hole"... Very nice!

In one of the best threads, I've ever read on the Internet, there is an explanation of a optical collimation device.

Then a little further down, the patent from 1974.

But start at Page 1, a lot of gold within.

You really need to put that picture on a T-shirt with some witty saying..
Like. ...I like SMOOTH CHAMBERS
or TWISTED or TIGHT CHAMBERS BORED HERE
You'll sell a boatload at matches or online.

Great thread. Tons of nuggets

Reminds me of the 007 intro. Need a pic of James Bond in the middle.
