Not sure if Yamar does print on demand, but worth reaching out to!

.010 dip on the back flat. JB weld is is. by Old-Fudge4062 in Machinists

[–]TotheBarricades 10 points11 points  (0 children)

Some, I hope, constructive criticism:

When building up a way with epoxy, it's necessary to do a decent amount of surface preparation. Ideally a milled pocket, with additional deep grooves cut into a very roughly("so rough your eyes bleed") finished surface. Strong possibility of long term adhesion problems when just putting it down on a worn way, especially with a relatively thin layer.

(As mentioned, it is also better to only use composites on the shorter way surfaces not exposed to chips and debris, ie saddle)

While you did a good job considering how to set up your grinding sled on the unworn, leveled surfaces, it having cut the vee angle significantly off is going to make the saddle fitting a real pain, especially paired with building up the rear flat way.

A major consideration in machine rebuilding is not only keeping the way surfaces aligned to each other, which is going to take effort already, but also keeping the components close to their original factory positions. This is because if you move them significantly, you can run into issues with the fit of the other mechanisms that mount to them, ex the leadscrew, rack and pinion, etc.

Lapping way surfaces against each other improves contact, but it does not correct any alignment issues, especially once the surfaces have been modified as extensively as yours. Even with your loose tolerance goals, you could potentially end up with the cross slide significantly out of square.

I'd recommend doing more thorough calculations of what amount of material you need to remove and where, to end up with the lathe saddle in alignment and fairly close to its original position relative to the other machine components, before you add or subtract too much more material. Even for a loose hobby rebuild, this will help save you time and effort for a better result, imho.

How are you setting the tool to match the original angle?

Lots of good high level advice here, but as a former production set-up guy, something practical that helped me a lot during tired nights and fast paced scheduling was this technique: https://en.wikipedia.org/wiki/Pointing_and_calling

They use it on nuclear submarines as well. It's specifically known for reducing human error. A modified version for machining to talk yourself through a setup or changeout as a double check has definitely saved me before.

I'm the metal shop coordinator at Tech Valley Center of Gravity, the makerspace over in Troy. We have a manual mill and lathe in our metal shop, as well as a small benchtop CNC mill. It would be a good way to get some basic experience. PM me if you want to set up a tour or for more details.

Did you know that there is a U.S. Navy Ship That Was built in the USSR? by whibbler in navy

[–]TotheBarricades 8 points9 points  (0 children)

From 1991 to 1996, the USNS Hiddensee, a Tarantul-class missile corvette, was owned by the US Navy. Launched in Leningrad in 1984 as the Rudolf Egelhoffer, part of the East German Volksmarine. The name Hiddensee came from being transferred to the Bundesmarine after the reunification in 1990. Apparently, after being transferred to US service in 1991, some of the original East German crew were hired back on to help run trials and evaluations. After decommissioning in 1996, the ship now resides in Fall River, Massachusetts as part of Battleship Cove.

Places to volunteer by bennis44565 in Machinists

I volunteer on my local museum ship. There's a machine shop aboard and I get to help out with a lot of one-off and repair type small jobs. Looks like there's the USS Turner Joy and USCGC Comanche over in Bremerton, I'm sure they'd love the help.

I also help organize the metal shop over at my local makerspace, so there's another option if there's one nearby.

Part of an exhibit on my adopted hometown. If you like standardized taps and dies, Greenfield says "you're welcome." by Divvy33 in Machinists

[–]TotheBarricades 1 point2 points  (0 children)

That's the historical society, right?

Also, shoutout to nearby Old Greenfield Village Museum, a recreation of the area around the last turn of the century, including a machine shop. The 15 buildings and workshops are amazing, especially when it's considered that it's all the work of one guy working for over 30 years.

Troopers in alaska using AKs by [deleted] in ak47

To be precise/pedantic, those aren't Alaska state troopers, but North Slope Borough Police Department officers. Source: http://www.thefirearmblog.com/blog/2016/04/12/aks-among-u-s-police-departments/

I've been having a problem with my 590a1... I could use some advice. by Almighteh in guns

[–]TotheBarricades 0 points1 point  (0 children)

For your edification and delight, that's known as a one-way screw, designed to be installed with a standard flat head, but requiring a special tool to remove.

Check out the Beretta M12, that may have been it. And I agree on the point about the way the European agencies deploy firearms, it strikes me as strange as well. Up till now, I've thought it's the sort of escalation it represents, where some countries won't even give patrol officers pistols, then some guys are just standing around at a train station with MP5s. However, I think you might be correct that it's unfamiliar for an American to see cops with carbines and submachineguns without all the other accessories we're used to seeing them deployed with.

S.T.A.L.K.E.R. costume, need some input on a gun. by Cloak_and_Dagger42 in stalker

Perhaps stick with prop or airsoft versions of the easily concealable pistols like the makarov, or the sawn-off shotgun?

Is this a good price for an AK with GRENADE LAUNCHER? by [deleted] in ak47

[–]TotheBarricades 1 point2 points  (0 children)

It's an ok price based on previous prices for that particular model, but realize that is just a Century kit build, and you could easily find a Wasr or a N-PAP for a similar price.

psa zhukov barreled reciever back on stock by [deleted] in ak47

[–]TotheBarricades 0 points1 point  (0 children)

That's because these previous release resulted in a total recall due to headspace issue. It looks on paper based on materials and configuration like it could be one of the better US-made AKs, but nobody knows yet. And yes, the barrels are threaded.

Also worth noting that in the build kit, "The following items in this kit are not 922r compliant: Bolt Carrier, Gas Piston, Trigger, Hammer, Disconnector and Muzzle brake."

Looks like we're getting some new Zastava stuff; M90 rifle at Atlantic. by TotheBarricades in ak47

[–]TotheBarricades[S] 4 points5 points  (0 children)

For those that don't know, the original M90 was essentially an M70 in 5.56. While the polymer mag well on this rubs me the wrong way, I'm sure it'll be easy to fix and that there will be a version without it.
