Rib #1 problem need advice

[bushfly]

I installed the spar attach fittings with Rib #1 already on the spars. Any suggestions on how to notch the rib so it will go over the spar attach reinforcements. See pictures.

I painted myself into that corner also. I vaguely recall that I marked the attach fitting locations onto the web of the rib. Slid the rib out on the spar to provide some working room. Protected the spar with a couple of layers of tape on each side of the web, and used an Exacto and small files to trim away the necessary web material. Yes, it was a real pain.

Dremel tool with cutting wheel (saw) to do most of the work. Finish cut with Xacto saw.

The only problem with the dremel is I was concerned about hitting spar since I can't remove the rib.

I wouldn't be too worried if a little more material than necessary is removed (not a "perfect" fit). Be careful of the spar, & fill any gaps with Hysol & flox if you need to.

Be careful, take your time and don't let the Dremel touch the spar.
