I have a couple of actions I would like to have Blue Printed (Rem 700 and Howa 1500). I was hoping someone can provide a recommmendation for someone in Ontario? I'm willing to ship the actions anywhere in Canada but prefer to drive them to someone in Southern Ontario if possible.

Thanks,
Moro
 
Why? What are you hoping to gain? You realize the barrel and bolt have to go with the action? And depending on what work is done, the current barrel may no longer be suitable for a reinstall?

I suspect that you are not overly clear on what is meant by "blue printing" a rifle action nor what work is involved?


To go back to where the term "blue printing" originated, one would not simply blueprint the engine block and then drop all the OEM parts back into it. That wouldn't help anything and would likely make a bunch of parts fit worse. The entire engine is blue printed, not just one part and blueprinting would involve a whole ton of new parts .... which is likely also true with respect to the barrel of a rifle.
 
Havent used them in a few years, but you could call Ellwood Epps.

Is that you Sunray??
 
Keith at milcun.com is set up to do M700s.

But the question you want to ask yourself is "Does the action need to be blueprinted?". Unless there actually is real justification, it is a waste of time and money.

FYI, (intentional or not), your tone comes across like a condescending dickweed. Take a moment of reflection.

To the OP, milcun.com or Epps (if they answer the phone...)
 
What exactly do you want done? Most people when they think of "blue printing" they mean just truing the lugs. But then there is also truing the barrel and the receiver to each other. Finally there is truing the bolt fact.

They aren't in Ontario but Corlane's Sporting Goods will do it all, you just sent them your action, barrel, and bolt.
 
Not "blueprinting", but here is what I have done.
Mount the receiver on a mandrel and true the face. Lap the locking abutments to be perpendicular to the receiver axis. Lap the locking lugs to the abutments, loading the bolt from the front.
I put one receiver on the mandrel and turned it externally. I was surprised how "banana" shaped it was.

Blueprinting is MACHINING to a set of EXACT specs . RJ

Thats not really correct. Blueprinting is the modification or correction of an existing part to bring it within the closest possible tolerances as specified in the original blueprints.

Machining something to tight tolerances is creating a new part.

Trueing up the action helps. Actual blueprinting is time consuming, and will be extremely expensive. Too much cost for not enough gain. I dont know where you are loacated OP, but pretty much every province has at least one smith capable of this. - dan

The thing that seems to be being missed by most posters here is that action truing or blueprinting is normally done before a new barrel is turned and fitted to the action. The OP did not specify but it appeared he was looking to have existing rifles blueprinted.

The notion of blueprinting an existing rifle without creating a new barrel to fit the modified action is a big problem. An existing barrel cannot simply be screwed back onto a newly trued action.

If one goes whole-hog, trueing an action can also involve recutting threads to ensure they are perfectly straight as well as trueing the bolt face and the front of the action. All of those things change the headspace and the trued threads will be super loose to the old barrel. A fully trued action will no longer accept the original barrel in a safe manner. A new barrel is a requirement.

The OP made no mention of understanding any of these factors, which is why I replied the way I did. And apparently a ton of people got butt-hurt by a person with a screen name "I DON'T CARE ABOUT YOU" responding in an acerbic manner.
