Action truing, fact or fiction?

You guys are killing me ;D Back on track, yes truing an action is a good idea when rebarreling. Once trued, its trued for its life. Its a one shot expense. Dont know what others charge but we charge $100 for it and it is good insurance compared to the rebarreling cost.
 
Wouldn't you rather be working up loads and shooting then second guessing the reasons why it may not be shooting up to par?

There is NO SUCH THING as absolute zero!!!!
Absolutely! There is also a static zero and a dynamic zero. I love it when Engineers start to ask for tolerances in microns...that blows this conversation out of the water.

I've done some good work with a precision yardstick from Edna's Fabric Outlet.

Hog,

I've heard that Edna's yardsticks are quite accurate when compared to run of the mill yardsticks. 8)

Ray,

Reasons that would make me second guess a gunsmith is when they tell me that their 1960 Hardinge lathe can hold tolerances down to 1/7 of a human hair. That the way they chambers barrels is a secret that only they have because a fairy god mother bottled the special pixie dust they use and handed it over to only them. I'd much prefer to work with a gunsmith who's name shows up at the top of a match bulletin, that's been there and done it, keeps their word with respect to lead times and estimates, and is truthful about their abilities.

^^^^^+1^^^^^^^
This subject is going in the "become a gunsmith" thread, also. The .0001 claims drive me crazy. Most people that make that claim simply don't have my trust unless they can explain to me how they can repeatably set up to verify their claims. I'd much rather deal with someone who knows better and is honest enough to say so. Measuring to those tolerances is hard enough, even in a laboratory environment, and machining to those tolerances in their basement is a whole nother level. Ask any tool and die man that does that work for a living. They'll tell you what time it is.
 
Scott, My uncle has worked for Harding Bros. for 40+ yrs and has a small machine shop of his own..
I now people claim things they can't prove but Hardinge lathes are well thought of and hold there value very well..
I took a gun to get rebarreled by a local gunsmith instead using my uncle and his small shop like before, I didn't know anything about what kinda questions to ask the Smith but I thought he comes recommended and he is a gun Smith.. I should have had my uncle do it at the time because he is a good machinist and has done a few barrels for folks over the yrs. long story short, when I had more knowledge and new what to ask the Smith that did a previous barrel for me I thought I was very lucky my other gun actually shoots okay..I asked him questions like how far does he indicate the barrels in off the bore? my answer I got surprised me a bit. "He said off the bore? I think those Hart barrels are very strait and I just indicate right off the barrel". Ya, I started looking for a well known Smith and asking questions for future builds and forget about the guys that say anything within .003 will shoot dead nuts..I guess I would rather see a guy trying to do it right and think he is getting near absolute zero then the guys that think "a couple thou don't mean nothin"..Experience in the machine shop usually makes good Smith's :)

Erik,

I didn't hear from you yesterday, and as I said, I didn't get any sleep because you didn't forward your approval of my method. Here is the method that I use and it's within a tenth as you keep stating. A tenth of an inch right?????

I can assure you that it's a very high quality tape measure. Heck, who needs any of these worthless indicators when a tape measure can read a tenth, right?? In fact, Maybe you'll do me a favor and take them all off my hands. What say you??

JS, I see that precision yo-you is a Lufkin. I think the Stanleys are a tad more accurate. By the way, how much runout on the headstock bearings while it is at chambering speed? ;D Do those indicators have jeweled bearings and how much wear do they have? A coupla microns? :)
 
JS, once someone like you starts trolling I don't waste my time.

I've seen pictures you have posted about threaded tenons you have done and I can tell you don't take as much pride in your work as people I'm used to dealing with. And now that I see your setup.... Well, at least you're consistent.

All others, interesting conversation. This should shed some light on shooters that are on the fence about blueprinting an action.
 
I don't usually critique one's setup, as there is more than one way to skin a cat, but I don't see anything jumping out at me as being wrong with that setup. How'd it shoot?
 
Oh my god Erik...My hopes are all dashed to pieces. I'll never sleep again!! What shall I do??
Wasn't my tape the right color? The right brand?? I am beside myself...
I am sooo sorry that I wasted your time oh great one..I am sooo not worthy of your greatness! It doesn't matter that you just started less than a year ago...I am still soooo not worthy! A thousand apologies oh great one! You are everything and I am nothing.

Sincerely,
Your ever faithful minion,

I believe what matters is not how long you've done something, but the attitude you have towards what you are doing. There are people with 30 years experience and there are others with one year experience 30 times. Simple as that.
 
Well, when you are on your 30th year, let me know...we'll look back at this and I guarantee that you will have a different view on a few things. But for now, peace out brutha!

Not to sound stupid, Wouldn't you like the indicating rod to be a touch longer?

Ray
I actually do. The one in the pic is a JGS, but I normally use the PTG which is significantly longer. Since I was measuring with a tape measure...well, ya know...
