I did, but if I may, I'd like to add a few things to your build's directions which may help people.
When you're putting heat shrink over the OEM ball, 1/2" will fit, however, it helps to pre-stretch it. It helps a LOT.
Look for a couple of plastic funnels. Yeah, like the kitchen ones. You want one which the heat shrink goes over the small end easily, but you have to work to get it to the 'bowl'. Some kitchen corn oil on the funnel shaft helps quite a bit, too.
Use your hand strength and twisting to get the heat shrink up as far as you can.
Let that stretch for say, 10 minutes. Now, get the hot water in your house running, again, to a faucet at which damage will be limited. Run the heat shrink, yep, still on the funnel, under hot water. Don't worry, heat shrink doesn't start the shrinking bit until about 190F, and that was the lowest temp I could find.
I can say , 212F, i.e. boiling, is a bit too hot.
Carefully work the heat shrink back off the funnel.
edit: I forgot to mention, don't pick at the widest spot and roll it off. Grab the shaft of the funnel and twist that sucker off with brute force. Being oiled helps.
Now, while it's still warm, put it on the larger funnel. Again, run that sucker up as far as possible. It helps to have the funnel pre-oiled. You should be able to get it close to the bottom of the bowl.
Let that sit overnight.
Yes, overnight. I've tried 10 minutes, 20, 30, 45, 90...it's best to just let it happen in its own time, apparently.
When removing this piece from the funnel's end, hit it with hot water, first, this way it just slides off, no wrinkling.
Lube the ball of the mount with corn oil, the stretched heat shrink should slide right on. The second one was a challenge, and the third...ooooh, the third.
I learned something on #2...you need more grip on the tubing to get it over the now-larger ball.
320 grit sand paper to the rescue!!!!!!!!!!!
I tore off a small, rectangular area, and used this as a 'gripper' on parts of the heat shrink which were going over the ball, and layers 1 & 2.
Between pre-stretched, corn oil, and using sandpaper as a gripping device, it went perfectly.
No pliers, no holes, no tears, no nothing but smooth heat shrink. Well, you have to trim the bottom, which is close to being a problem, but isn't quite.
