i think u are overthinking this. dont most routers have a consumable inner plate to cover the large gap around the bit?

There is a reason 80% Arms started with a large routing plate, and Modulus Arms went to a larger routing plate. I have a Dewalt router and the little "inner plate" of the router sitting on the little router jig plate of the Juggernaut jig is a problem waiting to happen if and when your mind starts to wander. If I was routing a polymer lower receiver, I could probably make it work, but good luck routing aluminum with that small surface area as support for router. 80% Arms has proven itself to work, why chance it for the newest and supposedly greatest toy?

Remember to go slow OP, especially around that safety detent notch.

Slow, cant emphasize that enough, and carbide bit for the holes if you have them, slow and straight. Again, just in case I didn't mention it, go slow. ha!

Smart move on getting the 80 easy kit, good for a few of those projects and you can still sell it. ;o)

Calico, how slow we talking? Several hours, or many days? Lol

Damn, I got that way beat. So I was mulling a lower a couple weekends ago and broke the router bit... Not going too fast but didn't wait for router to stop before removing it from lower. Anyhow it's at a workshop at an undisclosed location... So my timer is ticking at almost 2 weeks. Lol

Go slow everyone, or you will end up like me, and go super slow.

That's a milling jig, not a routing jig.

If you have a mill, you do not need a jig.

While I agree with your statement, some people use a drill press as a mill and find the jig helpful.
There are also people who have mills and do not know how to use them properly that also find the jig helpful because they can just follow the edge of the jig with the endmill and get a relatively correct pocket.

I use the side plates just as a fixture. scribe my lines with calipers and use a centering scope.

Thinking of doing an 80%, I have access to a machinist and mill, what jigs have proven their worth? I haven't been on CG for a few year either. What 80% lowers have proven themselves. Thanks in advance.
