| I WOULD APPRECIATE ANY INFO ON THE TOOLS REQUIRED TO FLATTEN THE RIVETS ON AK TRUNIONS, ALSO WHERE TO FIND THESE TOOLS. |
|
i've done my riveting using a hammer and rivet setting tool (punch) with pieces of scrap steel used as bucking bars. rivet setting tools are available from msc supply. i went really high-tech and bought an air chisel. i chopped off the chisel heads and ballmilled domes into them and i now use this tool to set any rivet i can get access to. you can pick up an air chisel on sale at harbor freight for $15. |
My plinker jig just arrived yesterday. Frank is an artist! I can't believe he is making these in his garage. It arrived just as in the picture above. Campy, have you seen/touched/tasted/heard about etc. this jig? What is your opinion (if any)? One of the guys in our build group spoke to one of the Bulgarian engineers from Arsenal at the SAR show and he said that plinker's jig looks very similar to the equipment they used in the "Old Country". Just curious if you have any thoughts. |
CAMPYBOB - Aren't those chisel bits hardened??? How'd you get the dome machined in without unhardening & re-hardening again??? And BTW - where does one find metric rivets??? |

Aren't those chisel bits hardened??? How'd you get the dome machined in without unhardening & re-hardening again??? the chisels are case hardened. the cores are only about 35-38 r 'c' or so. a carbide ballmill sinks right in. i got my metric rivet source at work, but i make mine from what's laying around the shop and use some of the ones in the k-var set. |

Quoted: Contact [email protected] for this... Looks interesting... How does it work? Is this a hammer-whack-it-till-it-looks-good kind of jig??? I was wondering how you get the jig to work on the rivets that are semi-hidden... |
Ah ha! Now I get it! (I was wondering how you got the air chisel bit inside the receiver)... You put the rivet in the receiver facing out, right? Then use your scrap steel bars to "hold" the rivet in place (probably with some kind of clamp) while you lean on the air chisel from the outside??? I think I could do that with a hammer and anvil setup...I'm pretty good at mashing my fingers with a 16 oz hammer... |
