Hi Leonard, check out the attached model - it should now boolean for you properly and give you a clean cut.

I scaled it up by 10 times in size - you can scale it down again if you need to have the final model smaller, but really the key thing is that when I created the sweep I made sure it did not run over top of itself and had some clearance here:
