I may well be re-inventing the wheel here, but I thought I'd tell you about a little cheap tool I just made.
At the last meeting of the local sci-fi modelling club, I added slanted tubes extending out of the back of my spaceship. The problem was how to fair those tubes neatly into the body. We had a discussion, and the outcome was this little filleting tool:
Pretty simple, eh? To use it, I rolled out a slender worm of Milliput, then kinda tamped it into place using the tool; then with the tool wet (saliva ) I used it to smooth out the putty. The end result was pretty good; I don't think it'll need much sanding at all:

I think it is a really cool little tool.
Is that a round push pin?
Yep, a round push pin. Low buck! One guy suggested using a bit of rod to shape the fillet, but the spherical push pin has the advantage of being the same shape no matter what direction the handle is tilted.
