I have a good lathe.
I was a fitter machinist 20 years ago {forgotten most of what I learnt)
I have a Clymer .22 RF finishing reamer.
I have a Norinco JW15 action & another barrel I wish to put into the action.
How do I Ream the chamber with the reamer ? i.e RPM, feed rate, type of cutting fluid etc.
Is there a website that can explain this or can anybody relate to me what I should do ?
Do I need the GO/NO GO guages ?

I can see the basic operation being fairly straightforward but this headspace & how it is measured has me fairly stuffed at the moment.

Thanks in advance for any help.

Cheers Morton

Go to "PracticalMachinist",and log on to Gunsmithing.
Why are you replacing the barrel?. My J15 shoots very accurately.
Good luck!

Please please please order a book or video tape on this, if you can't get a smith to teach you....

daryl holland does a video on chambering, while not perfect, aint bad

if you are using a HSS reamer, ~150 rpm is good, and let the reamer tell you how fast to feed.. believe me, if you have any feel at all, it will shout at you when you are overfeeding

The Complete Illustrated Guide to Precision Rifle Barrel Fitting by John Hinnant is a pretty good book, and like jeffe said, Daryl Holland’s Video is good... if you can put up with all his self-promotion and sales pitches for his products.

I have no idea how many chambers I cut in a year but I cut all the 22LR chambers by hand with a T handle. It takes twice as long to set up the machine as it does to just hand cut it. They always come out perfect. Rod Henrickson

Another vote for “hand-jobs!â€

Thanks Hawkins the practicalmachinist site is just what I`ve been looking for.
As for the JW15 barrel, it`s completely rooted, been left in a shed for a few years and had water or the like inside & badly rusted & pitted.

One option is to line it to a 17MKII. If you can get them they are interesting. I did an old
Srevens Favorite, it my be the most accurate gun I own now. The 22lr head spaces off the rim, if it closes snug on a piece of
Scotch tape it is good .
Good Luck!

Wstrnhntr,
You are 100% correct in your suggestion with regard to gunsmithing & this forum.

But I also have much to relearn about general machining, why I say Practicalmachining is just what I`m after.

Please don`t think I`m in any way trying to say this forum isn`t the best around.

I fully agree it is & I`ll definitely have a hatfull of future questions for the wise ones out there in cyber space.

Cheers Morton
