Default Chain clevis lock

I'm thinking about making some of these for my aircraft chains. I found a pin(bolt?), I have the spring, now I need to figure out how to make the lock tab.

Here is a link showing the lock tab:

I have a plasma, but it is kinda bulky for something like this. Would this be a candidate for someone with a plasma table?

I was thinking I'd make it without the little tabs, but then it would just swing round and round. Any ideas?

That is an interesting idea, simple concept as well as burning one out and bending the tab. I mainly like the idea of locking it if you find the right size padlock.

Nothing is wrong with what I showed. I have some grab clevises that I want to make those for.

No need to buy the whole thing when I already have everything but the tab.

Looks to me like the pin must be pressed into the locking clip

You need better than A36 for the pin, unless you downrate the chain/hook assembly to less than half.

Well, I wanted to at least see if it was possible to replicate, so here is my attempt. It works surprisingly well. I guess I will go ahead and attempt this with "rated" materials. Thanks for everyone's input.

Rob, does it need to be open on the end? Seems like it would be much less likely to get bent or damaged if you cut a slot with the outboard end closed, then bent it.

I like it. I may have to replicate!
