Jim See from center shot rifles is doing mine right now, I'll let you know how it turns out when I get it back from him.

I can do em. Made a whole pile of tooling for these years ago when all I did was NRA course guns.
Chad,
Is it harder to true Win M70 actions than the round stock actions like the M700s? Can they be trued equally well if a gunsmith has the right tooling? Even with the M70 tooling, does it still take more time and care than the round stock actions?
Lastly, with the correct tooling, can they be machined as true as any other action?
I've heard and read rumors in the past that many smiths prefer to work on round stock actions. I presume the extra difficulty is associated with getting the M70 or other non-round stock actions positioned in the lathe so they're running true prior to touch up. But I've never had it explained as to why the additional fuss. Thanks,

The last time I trued an action in a lathe was 2001 so to be honest I can't even remember!
I use a CNC mill for the bulk of the process. Due to the fixturing I have it doesn't matter if the action is round, square, or a "dodectagon" (whatever the hell that is)
I imagine if using a cats head to tune a receiver a bit more care is required for an action that isn't symmetrical all the way around. Be that as it may it's still not a big deal because your indexing off the bore center regardless.
Hope this helped.

OK.
On a more basic level, the tooling for a M70 is different than for the M700s or other symetrical actions?
It is important to have tooling to index off the bore centerline, and that tooling will be different for some of the different actions?
Does a non-machinist guy like me confirm a smith has M70 'tooling' before sending a M70 action off for the accurizing work?
Thanks again,

I hate questions like this because I always get self conscious about sounding like an arrogant person.
How I do stuff is largely different than what the masses are doing. (don't start stoning me now as I'm not claiming better or that what someone else does is "less" then what I do) I say this because I don't profess to know or be skilled in the ways that most gunsmiths true an action or fit a barrel. I've gone in such a completely different direction with my stuff that I'm a poor choice for an opinion.
I don't have a crystal ball into other shops to see what they are up to. I would imagine that it starts with you doing your homework as a consumer. You research a potential smith and see what his feedback/reputation is. You then ask if he can do the work your after. Most of the guys at the higher level are pretty straight up so if they say sure, then I would have to assume you'll be treated right.
What were talking about is not rocket science. This isn't mold or die work where you have to accommodate for material shrinkage, elongation, distortion after heat treat, work hardening, etc.
It's rather simple fundamental machine work just ensure stuff is running on the same center, is round, and at right angles/parallel to one another.
Good luck.

Fair enough. Thanks for your input.

I sometimes dance a fine line here because I am not yet a sponsor. I do my best to avoid making blatant statements that can construed as soliciting.
That being said I think it's best if I avoid posting my site in a public forum as it takes away from those who are spending hard earned money to advertise here. PM me instead.
Point being I don't want to **** people off.
