Was talking with a few people about the UBAR3 and using a M5 nut in a recessed pocket for the grip screw. Looking at the files there are about ten different versions of the UBAR3 but I couldn't find anything about the differences? The file names are clear as mud.
I used those magazines in another project, the printed ones failed before two full mags. The ones with metal feed lips lasted quite a while, even left loaded in climate controlled area. They only met their demise when I forgot they were in the hot car.
Yes, corrected it
The standard AKSS cam rotates on the factory selector which is not used in the plastikov, and other parts of the plastikov frame are in the way. You would need a complete redesign to get an FRT.
You could use a standard AK binary, but you would be stuck with two position. Three position requires a standard FA AK selector.
I've had good luck using default settings until printing tall boys. I know doing two at once probably isn't the best idea but it did help to show that my issue presents itself when there is a drastic drop in layer time.
Using orca, any recommendations for setting fan speed@ height when using PLA plus?
Issue has ONLY occurred when printing tall mags, close to 250mm tall.
Here I am saving my pennies for something else and you keep posting about this. 
Are there any other .45 upper options? Anyone know if the vmac bolt has features to activate a trip bar like the 9mm does?
I've got a .45 itch to scratch. I'm Mac dumb.
Good job man, I know it was both a mess and a highly desired project.
Couldn't figure out how to add second picture to original post.
Remix of RG3D prints ACR style stock for direct fit on Cetme C or G3. First version came out higher than I thought it would. Basically impossible to aim with irons. Next version is 15mm lower and there is still the option to use the built in cheek riser.
I bought the Q2 on sale without the box about a month ago. I haven't used it with any fancy filament yet but it has worked great with easy set up.
Also, my understanding is that the dry box is just to keep it dry, you'll need something else to actually dry wet filament.
I'm very happy with this trip bar geometry, most consistent results yet with repeatable release timing. It's probably a little late but working and I'd rather err on the safe side.
Need to finish the CAD for the metal trip bar now that I know the starting length and get that coming. Surprisingly the plastic held up, much better than expected.
Also need to start over with a fresh hammer and try and get a profile that works without welding. I had the hammer good with a big ass shark fin welded on but I found the limit trying to trim it down.
These are probably the most commonly imported kits, and were always some of the least expensive.
Yes, not a bad price. Only caveat is that some Romanian trunnions had variation in the rivet hole locations.
Looks nice, I've always been a fan of these sights.
The T.I.T.S. iron sights have a windage adjustment that uses an m3 or 4 volt, captured nut, and a locknut. I've used this set up in a different set of sights and it worked well and didn't require special hardware. Perhaps singing similar could be adapted.
How'd you get elevation on the drum?
It would take massive legislation at the federal level to ban PMF or unserialized firearms. While most people think of the 60s as ancient history there are a lot of factory firearms out there made before GCA. Any new legislation would have to address this somehow.
What is more likely is a state ban. What could go either way if of it banned me manufacturing or possession.
Either way if what you're doing now it's legal there is no future threat for what is already done legally. You'd have to interpret any new legislation and act accordingly.
It's impossible for them to know about every transaction that 'could be' a firearm part.
Guide for locating your FCG and selector holes in a bent AK blank. Also has trunnion holes which I DON'T recommend using. I have a separate fixture for those.
SOT only hole included, don't use this hole unless you are licensed to do so. Stay safe and legal.

This fixture holds your front 23mm AK trunnion or fixed stock rear trunnion to locate your rivet holes in a bent blank or receiver. My Odyssee also has a short video on how it works.

Ah, I didn't have much time to read and skimmed it and missed it. Doesn't sound like anything that affects the grip nut.... Thanks!
