Thanks Richard, I reckon your right. It's a,big problem best avoided or tackled by far more skilled hands than mine! 😂
If I find myself getting obsessed by that kind of detail (and I do - a lot!), sometimes it pays to try and work out just how big it will be on the model
Those anchors look about two inches long. That's 1/16" or 1.8mm. and that part needs two holes drilling through it...
Bet I could fake it with copper wire and paint mush more easily! Put two anchors close together, rig the wires, then fill the gap between the anchors with black paint. Dab on some silver if you want to represent the shackles
And... none of that will have anywhere near as much impact as your lovely roundels and weathering.
Richard
