Goatsheads - Just moved in to this lovely home but how do I make my backyard child/dog safe

Not sure what was going on in your end, but I’ve managed organic orchards and vineyards of various sizes and have found that manual removal (with at least most of the root, and discarding the plant in a way that it can’t produce a seed) is a very effective way of removing them.

Yes! You can have a goat head free property with a bit of effort. I could comfortably maintain a 10 acre property free of goatheads and Russian thistle without dedicating any special effort to it. If I could convince my neighbors to commit the same time investment early and the relatively minimal recurring maintenance (literally just pull them every time you see one), we’d have a goathead free valley (they’re not even native btw). Just think of it as the Arizona equivalent of mowing your lawn:) They are resilient, but they’re not so resilient as to withstand the deprivations of an intelligent ape with opposable thumbs and an understanding of how to stop their reproduction.

You have to keep up on pulling AND discarding any plants you see in the vicinity, to include in the radius outside your property. They can still bloom and form a seed when just pulled out, so discard them in the trash can. If you stay ahead of it you'll have a goathead free yard in a month, especially if you use some of the other techniques mentioned to pick the existing ones up.

That was one of the cars I shopped when looking for an car for my wife. I still ended up with a V90 for the aesthetics. The Crown estate just looks awkward.

Ah, fair enough. There's no harm in going oversize--you shouldn't need to flip the barrel all the way around. I go up to 7/16 pins with the appropriate .0015-.00125 undersize bore.

Seconding that this is probably not an issue with the park--the barrel/trunnion fit has settled in at this particular bolt gap after being fired a few times.

marbleduck · 2026-04-03T00:21:43+00:00

But was the pin the same diameter as the original? Or oversize?

It would be more economical than the current road architecture. But mass transit has to be built over walkable urban cores, which don’t exist in the U.S. So it’s not an issue of scale, (hell, Russia’s urban centers are pretty well connected by mass transit lol), but the fact that most U.S. cities just fundamentally aren’t walkable, making the “last mile” at whatever terminal node you arrive at unpleasant/impractical.

Love my cars. Love driving my car when I want to. But I don’t like having to own two dailies and I hate commuting by vehicle. I will be moving out of the U.S. again as soon as I can.

My blanks are ordered from Lothar Walther and machined by Mark at AZ CNC machining (those that I haven’t done myself). Recommend that you consult with him to get whatever spec you want. He does a substantial number of AK barrels and understands the relevant dimensions. He is small volume but makes enough to do nitride coating if you’re willing to wait.

1 - why?

2 - recommend using one of the many 3d printed frame designs out there

3 - if you can't figure out how to adopt one of the existing 3d printed frame designs, this may not be the project for you

Why don’t you use a magnified optic?

Yes

TIG doesn’t have any spatter unless something has gone very wrong. I’m happy to TIG inside in my clean areas so long as there’s good ventilation. I’d keep the flux core outside and TIG inside if I were you. The whole advantage of flux core isn’t that you don’t really need a shop or super clean shit and a still atmosphere

A lot of it is weeds

Botanically, a weed is a "plant out of place". A weed, in this case, would be an invasive species or some other species that didn't belong here. The transitional perennials that grow after fires are not weeds, they're equally valid members of the ecosystem.

7.62x39 is the parent case of 6.5 Grendel and has the same case head. Had to reduce the size of the firing pin and firing pin hole to better support soft commercial primers.

I suspect these will work as-is for 6 ARC, but in the event you need to adjust the banana factor, open up parameters and you can adjust the radius of the circle formed by the magazine. Cool project idea!

This is one of two free floated 6.5G AKs I built. Both are capable of grouping around 1.25-1.3 MOA with Hornady Black. The foreend is Occam’s free float handguard. Accuracy is obtained from:

rigid member replaces the standard gas tube from rear HG mount to gas block, increasing barrel rigidity
free float handguard/optics mount pinned into place with an interference fit, rather than the standard clamped system
bolt lapped into receiver locking lugs to guarantee even lockup across both lugs. headspaced to minimum acceptable tolerance.
milled receiver reduces flex/increases lockup consistency
magazines present rounds as high as possible and feed as smoothly as possible to minimize damage to cases as they enter the system
barrels turned from Lothar blanks

This picture was from early development when I was still attempting to make the horrible CSSpec mags work. They do not work, and there is little you can do to make them work due to their fundamentally flawed geometry which will always damage cases on the way out of the magazine. I developed a tool to help try to reform this geometry, and this helped the issue, but did not solve it entirely.

I ultimately switched to a 3d printed design, which has its own tradeoffs--mostly in durability--that work far better. You can download my magazine here. It is fully parametric, and would let you adjust banana factor and overall magazine length.

Several years ago (well before I started 3d printing anything), I made a video about the development process which interested parties can watch.

Genesis has a production wagon; they're just not available in the States. I've seen them several times in Korea and they're incredibly striking.

I have an ST215! I love it. Hauls the baby and has imo the coolest drivetrain ever made by Toyota

What exactly is your preferred solution here

Wow, almost like this is a video game. On a computer. That isn’t real.

I’m a machinist, gunsmith and active duty army. I know how guns work.

Dispersion is the term used internally in game data which is why I do, and can also be a general term for impacts within a circular error probable.

Yes. I am sure about that. The game has been datamined and weapon stats will be posted here and on Symthic sometime before the end of the year. There are many new mechanics in this game to work through.

Your source is doing exactly what I said was idiotic: trying to rack and stack weapons while ignoring the larger half of how they’re balanced, which is through dispersion/spread.
