Sweep angle to face

Good day everyone,

I am novice designer and have been trying to learn Onshape since I graduated from undergrad. My first self project was to recreate a simple distillation apparatus. However I am having some issue, trying to create the condenser part. The condenser should pierce through the cylinder until the inner wall. However I am not sure how I can accomplish this. I have tried using the loft feature and that works but I am not sure how to specify the end point of the inner face of the cylinder.

I am attached the link to the file and an image for reference:

The highlighted area of the inner cylinder is where I would like the loft to end. However I am not sure how to accomplish this.

Any guidance offered would be appreciated.
