Default No room for the countersink cage

I'm supposed to countersink #30 the rudder stops, although there's no way the cage can fit inside that angle. How do you do this step?

Most people obtain a second cage and cut away one side.
Another option is to remove the cage and carefully "freehand" the countersink.

Everyone has that problem. You have decide what is right for you. I think I wound up taking the CS bit and putting it on my deburring tool and hand cranking that. Not show quality, but certainly acceptable. Those rivets were a little difficult to set too, can't get the head of your flush mount rivet set in there. I wound up using a flat piece of steel and using that between the rivet and the flush mount rivet set.

I used my hand deburring tool for these. You will find other areas where this tool will work nicely for the countersink.

+2 to hand deburring tool ... once I got some practice I found myself going for this tool vs the drill and cage as it was more convenient, especially on fiberglass.

Wish I saw this a few days ago. I figured out how to CS by hand with a deburring tool. Came out ok. Happy to say, i use a cage on all my other CS work.

One quick note, If you use a back rivet set on the manurfactured head of that rivet, use electrical tape on the manufactured head and push real hard. Or, your manufactured head will bulge up.

I've been hand drilling the countersinks in my cowl using some carbide-burr countersink bits with great results. Go slow, and check often. All have come out just right.
