What tools to use?
Hi Gents,
Just a simple questions. How to make knurled (?) pattern like on SilencerCo suppressor tube? What tools are required? Thank you.

Re: What tools to use?
If you have to ask that question , I dont think the rwst of the machining is going to be up your alley either. Think end mill.

Re: What tools to use?
Nothing wrong with asking a question.
They are done using an endmill on a CNC mill using a 4th axis.
I guess you could do it manually using a rotary indexer but it would be a pain.

Re: What tools to use?
I've done something sort of like that with an endmill, scribed lines, multiple re-clamping, and lots of spinning-o-the-handwheels and counting turns.
As was mentioned, time consuming PITA. Would just knurl it and call it done.

Re: What tools to use?
rotary 4th axis indexing with a flat endmill. The feature is created with a plunge cut so a centercutting endmill is required.
Keep calm, and suppress on

Using the side of an endmill would be much better for tool life, surface finish and would also create a better blend into the top surface. It almost does look like there are swirl marks from plunging an endmill but it is really hard to tell when I blow up the picture. I also can't tell if there is a sharp step between the max OD and bottom of the notch. I know if I were to do it, I'd run the side of an endmill, taper in/out of the cut and index with the 4th.

Re: What tools to use?
Just wondering if anyone has used our tooling here to complete a form 1 project. Any feedback?

Sorry about that. I just saw the thread about the tooling used. How can I delete my post? I don't mind removing it.Bendersquint wrote: Probably be better to start a new thread than hijack one.

Yeah, but you wouldn't, accurately, replicate the finish created.300sniper wrote:ChimeraPrecision wrote:rotary 4th axis indexing with a flat endmill. The feature is created with a plunge cut so a centercutting endmill is required.

To the OP:
You could make a jig, to hold you tube between centers, out of plywood.
A simple indexing plate, on one side, would help in keeping radial seperations equal.
This is for jeweling a bolt, but honestly, the setup is the same for either. Just a different tool bit in the chuck.
Align Jig
Fix Jig
Set Depth
Make cut
Rotate per your particular separation angle
Make cut
Repeat until first rotation is complete
Move jig laterally
Divide separation by 2
Repeat
Personally, I would practice on a scrap piece of pipe, beforehand.

Re: What tools to use?
There is a place by me that does NFA engraving maybe a laser engraver can take 3-4 passes and get down to say .010 and be sufficient.

Gents, thank you for feedback. Seemed I need to forget to have this pattern on my home build, it's beyond my skill.

Could you drag a drill press over to your lathe?
If so, you could use the lathe as the indexing head and plunge the end mill with the drill press.
I'd put a center in the lathe to align the drill bit to, before proceeding.
Try it on a piece of pipe before you tell yourself it is un-achievable.

Re: What tools to use?
It sounds kinda hokey, but I've seen guys mount a tube or something they need to mill out on their tool posts and run an end mill in their lathe. Maybe take your tube and make some alignment marks around it then line that up with the jig you create.

T-Rex, thank you for encouraging me, I greatly appreciated it. I will try it next weekend.T-Rex wrote:

Re: What tools to use?
Yeah nothing wrong with challenging yourself. That's the joy about this stuff is you get to be creative. Post some pics once you try this out. Who knows you may find a great way to do this that a lot of guys would love to learn from!

JohnnyO, excellent work man! I think I'm gonna find some one who can do this to me. Is it legal to send suppressor tube to US to get this machined?

Suppressor parts need a tax stamp, and for US it is not easy to bring in Silencer (parts)
You will be able to find a machineshop local that will be able to do that, no problem.
All you need is to specify the spacing, amount of cuts, cut depth, and how many rows will be around the circomfence of the tube.
