>>214shouldn't you be able to find detailed and exact measurements of all the receiver components online? I would think that this "approximation then refine" strategy would be a huge disaster and time suck

would anything in ar180s.com be helpful? eg:

>>215>I would think that this "approximation then refine" strategy would be a huge disaster and time suckwhy?
a time suck sure, but not that much of a time suck. I wouldn't build a whole rifle on my first receiver, presumably i'd be able to refine it before then
certainly not a huge disaster. its how many obscure homebuilt rifles are made, and when things are hand fit nothing really matters that much anyway because you're fitting on the fly

getting some inconsistencies regarding looking at the flats. my reference flat is slightly different than everything else ive seen
No.226
30 dollars to get it 3d printed
overall dimension not actually that big
a tad over 7 inches long, less than an inch and half wide
might by one of those nodak spud receivers soon and print out a trunnion and receiver to check dimensions
No.238
developing some tolerances right now for parts.
need to buy the lower receiver to get a better idea of the upper receiver dimensions
No.239
not to get ahead of myself, but im thinking the way the trunnion is set up can be simplified. having it set up to take your standard AR15 barrel would be a plus, except theres not enough room for the index. would have to redesign how the handguards go on to. probly make them split on the other plane for simplicity sake

i must have been posting all my updates in spee because none of it is here
just spend the night having serious autism and designing what im hoping will be my bending jig
i got inspired and doin my own design. will see if thats a mistake or not

No.494
just list everything ive done since 2019:
>switched to solidworks, remodeled everything
>multiple 3d printed iterations of receiver and trunnion to narrow down the placement
>MJF printed buttstock, buttpad, prototyped a rear sling swivel to stop stock rotation
>95% modeled handguards, heat shield, front sight block, handguard retaining ring
>picked up an AR18 front sight
>found out the AR18 gas block diameter is way smaller than an ar180
>need to either reprofile the barrel (its an insane heavy bull barrel) or get a new one
>getting new one would be the simpler and possibly cheaper option
>also wouldn't have to headpace it which would make life easier
>guess i could sell the ar180 barrel?

sorry i mean ar180b not ar180
