Straightliner59 Posted Thursday at 11:41 AM Posted Thursday at 11:41 AM (edited) I needed some CV joint dust boots for the 914 I'm building. I used a 1/8" shank 'v' cutting bit in my lathe to make this little forming tool from aluminum. I bored it to accept the .052" aluminum wire I'm using for the half-shafts. Then, all that was necessary to do, was to slip a length of heat shrink over the half shaft, and the form, and heat it with a lighter. I think they're pretty convincing!

Beans Posted Thursday at 12:11 PM Posted Thursday at 12:11 PM Looks great! I don't have a lathe but I'm sure I can come up with some way to make a form. Great idea. Time to experiment. 1

Great idea. Time to experiment. If you can hold your drill in place, somehow, maybe sharpen a dowel with a pencil sharpener, then chuck it in the drill, and use a triangular file, to cut the grooves? I was thinking about that, because, not everyone does have a lathe.🙂 1

peteski Posted yesterday at 08:06 PM Posted yesterday at 08:06 PM Good idea, but to me the bellows shape is a bit softly defined. There are many different types of heat shrink tubing available. I suspect that using a thin-wall tubing would give even better results.

I still think they look better than molded plastic.
bill-e-boy Posted 22 hours ago Posted 22 hours ago Shrink tube can be made to stretch a little some the wall thickness can be kept down. The amazing thing about HS is it will normally shrink to half of it's original size Being an industrial sparkie I use it all the time

I too have worked with heat shrink tubing for decades and used it in unconventional ways. 1
