We Need A New Forum Section For Machine Work

We need a section just for machining projects to share our work and help others that want to get into this part of the hobby learn how to fit barrels and make other parts for their airguns. If you're interested in this cast your vote here to let the forum owner know. Thanks James

I’d like to begin this thread compiling existing AGN threads dealing with machining discussions, tips, suggestions, videos, and tutorials related to airguns and airgun shooting sports. I’ll be adding to this list as I take time to do so. If you see something similar or relative to the theme of thread please post a link. This a a community thread let’s make it a point to keep it on track.

Carriage stop for the lathe

I made this carriage stop/Indicator holder so I have one for each of my two South Bend 9's. Just made it up in my head, you know. I can use either the thread insert or the slit sleeve to hold a dial indicator. I made a square head bolt so it uses the 3/8" toolpost wrench. Same as the carriage...

Machining Question

OK, I've got a sherline mini lathe and I'd like to machine some o-ring grooves. What type tool is best for cutting an o-ring groove in aluminum or delrin? Are there specialized tools or cutters? Could a thread-cutter be used...

(1 of 2) How to machine a barrel blank on hobby equipment (new .22 for my BRK Ghost)

I figured I'd share my experience machining up a LW barrel blank to fit my BRK Ghost. There are some good videos on youtube but not many that cover airgun barrels on hobby grade machines. Starting point: BRK ghost .30 cal. Objective: machine a .22 blank and the .22 probe. First a few pics...

(2 of 2) How to machine a barrel blank on hobby equipment (new .22 for my BRK Ghost)

Next step is to move over to the mill to machine the flat for the set screw and open up a transfer port. Due to the stick out, to reduce chatter I supported the end of the barrel. Transfer port was cut to similar dimensions as my .22 FX barrel. I skipped a picture of the process, but you can...

Machining Plastics - How to Make a Poppet, Regulator Piston Seat, etc

I recently read a thread where @Vetmx made a peek valve seat or maybe it was a regulator piston seat. Anyhow, I’m interested in learning how to do this. Can those of you who have done it, explain the process or point me towards a good resource to learn how to make these parts? Please share...

Decided I Wanted a CNC Router For Stock Making

So I built one! https://www.youtube.com/watch?v=0Cevyx_hIm0 Here is a whole bunch of worked rolled into cutting my first "real" stock blank, a piece of natural birch laminate. https://www.youtube.com/watch?v=EBqgbO-tV_Y

O-ring groove machining

Hi , I would like to put a hexagonal Lothar Walther barrel on one of my guns ; the problem is : how to machine the tiny groove inside the chamber of the barrel for the O-ring? What kind of tool is needed to do this operation on a lathe , or on a milling machine , as the bore is only .25" in...

N/A - Guide Making on a Lathe For Beginners by a Beginner

So my goal for today was to make a video detailing how I make a TX200 guide out of acetal on a mini lathe. I spent the better part of the afternoon making this video only to discover during editing that all of my source material for the second half had no audio. Why you ask? Because I am dumb...

Help with lathe

Im trying to teach myself to make my own guides but seem to have run into some issues. My cuts seem to start out well but as I get closer to the chuck I start to get "ribs" in the material. I'm a complete beginner so any advice is appreciated. Thank you!

One for you hobby lathe machinist!

I have a medium sized lathe, while it can produce some good results, heavy cuts and particularly parting off or long boring bars causes chatter, and as everyone machinist knows once is starts it’s difficult to get rid of. After watching numerous YouTube clips I decided to remove the compound...

Given the rise of 3D printing this thread/sub-forum may need to incorporate 3D printing posts too…

@MartyMcFly I thought about that. I would think that 3D printing would fall under its own discipline/sub-forum as it seems to rely heavily upon computers, apps, software, etc. and therein lies a critical divergence. Although the design aspect seems similar across both methods of manufacture.

Anyone else have thoughts on this?

Some discussion on crowning, cutting a leade (including discussion of straight and tapered reamers), etc.

Finishing A New Barrel Blank ?

I'd like to try my hand at finishing a new barrel blank. I understand concentricity, crowning and threading. Could some of you with hands on experience talk about the pellet chamber and lead in? I learn fast so share all you're willing. Do you leave freebore or try to start the projectile...

A list of barrel liner manufacturers and websites.. Like TJ's liners and Redman barrel liners... Reasonable price American manufacturers..

.... would think that 3D printing would fall under its own discipline/sub-forum...

Also, when we talk 3d printing...FDM and LCD is a huge difference what parts you can produce, some parts projects can overlap but mostly there is a contrast. For a serious work you would need at least one of each.

For 3D printing devoted to AirGun stuff (Mostly anyways).
Good resource

Maybe we could start our own forum since requests fall on deaf ears here.

Sure... Starting one is EASY.
Settingup the software... not hard, just a lot of stuff to name, fill in, access etc etc etc . Just grind thru it.....

Maintaining and runnig it day to day, is a time commitment FEW understand if they havent done it.........

It's just not very user friendly, same as here. I'd like to have a forum where guys can be guys without worrying about offending a sponsor or any other nonsense. There would still be rules like no discussion of illegal things and no strong political or religious discussion but at the same time not be heavy handed or overbearing.

I've done it, still do it and it's not bad, I just don't want to be tied to it alone. I'm still thinking it over.

Yea, I see where you’re coming from. Maybe the better option is to have a “DIY Manufacturing” parent thread with sub-threads for lathes, 3D printing and CNC. That said, I think that in terms of software and complexity the two disciplines are converging. The Chinese lathe I got a few years ago has plenty of digital enhancements to veer off the old school path and the newest home CNC machines (i.e Coast Runner) and mills are getting more advanced each day.

[sb327]

My opinion is that from an airgun forum point of view, the diy (making your own parts not assembling sourced parts) would cover all of it. 3D , machine (manual and cnc), hammer and file, etc.

To narrow it down simply narrows the ‘need for’. We have to admit, creators of parts are a minority here.

Would it be nice to have dedicated areas, sure, I would like that. But it’s not my sandbox….(although I am a product being sold here…).

But if we follow that logic this forum would only have one section covering all topics. Machining is it's own discipline just like benchrest. We don't want to wade through everything looking for specific information. 3d printing does not belong in machining and machining does not belong in DIY. It need to be more like a library. The less we mix topics the less people go off topic and derail the thread.

I agree with this and understand it completely. That would suit me personally just fine. I was trying to look at it from an airgun forum perspective.

@MartyMcFly When I read CNC threads and posts, I can see the areas of overlap between that sort of designing and machining and 3D printing clearly. A lot of it seems automated. I didn’t see that so much with lathes (I don’t know much about mills). Honestly I think that 3D printing needs its own space due to the differences in manufacturing a finished product, material differences, and tolerances. If one could make the same products on a lathe, mill, and a 3D printer, then sure why not lump them together? Think of slug/pellet molds or airgun barrels.
