    Are they bare or do they have nitrite coating?


    They are mostly in the white right off the production floor. A few here n there are coated but marked up. This is inventory that has shuttled around over a span of a few years. Because they came from the production side the bulk of them had never made it finishing/coating. -Another reason why I priced them the way I did.
     
    A little status update:

    We are processing the orders and they are shuttling out the door well. I admit to underestimating this a bit. I had around 20 or so combos ready to go. They went much faster than I'd of ever thought.

    So, Wednesday and yesterday we were working the 5x pretty hard as ever. Around 30 or so bolts got done and were about 2/3 of the way there on receivers. Those will start processing to head out today as well. Were going to burn some weekend oil and puff up the stockpile a bit so that the waiting is kept to a minimum.

    Thank you all for the interest in this and we sincerely appreciate the business!

    All the best,

    C.

    I just associated "action" with "gun" so thought this was the appropriate section. Truth be told I didn't even realize Frank had a section dedicated to SP's till you said that.

    You mentioned a little while back that you wanted to be able to push out 700 actions with the full treatment these lefty action have for around the $500 mark. Is that looking like a concrete possibility?
     
    No offense intended here. Just saying if it looks like a duck,(chatter on thread leads)swims like a duck,(thread mill chatter and burrs)and quacks like a duck(using the "F" word in your advertising) then its probably a duck. You posted the photos. All machine work is less than desirable but in reality its probably worth the price. Understanding rigidity and tool pressure are your friends.


    1. It's not tool chatter. Have you ever threadmilled anything before? Here's some 101:

    You have Arc movements, G2 or G3. Clockwise and Counter Clockwise. When you turn those into a helix you can do it either by splines or by I, J, and K values added to the basic G2/G3.

    I run them as splines which means arc motion gets converted into short line segments. That is part of what you are seeing.

    2. Single point thread mills vs. thread Hobbs:

    A single point thread mill is typically a 3 sided tool that winds the entire length of the thread, start to finish. A Thread hobb will typically only make one or two revs, then its done. This of course depends on the overall thread depth and the LOC of the tool.

    A single point thread mill takes longer, but I like it because the tool pressure is the same from the bottom of the hole to the top. A thread hobb in a case like this will either increase or decrease the tool pressure depending on which way you are running it. (climb milling or conventional milling) The issue here becomes less tool pressure on entry when conventional cutting a RH thread or less pressure as the tool starts to exit from the top (climb milling)

    What does that spell? It spells a thread that has Hellmouth. AKA, a hole that is tapered like an icecream cone. My threads do not do this.

    But you knew that as clearly your a machining Xpert.

    As for rigidity. The part is held in a 16C collet and my tools are from Horn USA and mounted in a Parlec shrink fit holder. But again, your clairvoyance obviously already knew that.

    Quack away Aflac, lol.

    Thanks for wasting our time trying to convince all here that your a top notch CNC button pushing cowboy. Obviously your still learning kid. Everything from a book and and what others have told you bracing on their opinions instead of forming your own from years of experience. By the way I was machining and and reverse engineering when you were still in diapers and I learned taking short cuts won't get you quality parts our in your case surface finish.
    I would be more than willing to give you a hand solving your machining issues but your bullheadedness would stop you.
    Give yourself a brake, I've had plenty of your type work for me in the past, can't take any type of constructive criticism.
    Thats chatter and those are burrs it can all be resolved but it all gets covered up right?


    ....and blocked.
     
    I picked mine up yesterday. Unpolished stainless action with a matte black bolt handle. The guy at LRI said he thought that the bolt handle had been parkerized. I had them spiral flute the bolt body for only $30 extra. All of the machine work looks great. I'm happy with it.
     
    Just ordered all my other parts today to complete the "builder's special". Once I've got everything I need, it'll be headed right back to Chad to get a barrel spun on and finished.
