HOW WE IMPROVED WAGTAIL SQUEEGEE SWIVEL MOVEMENT USING A PVC WASHER
So put this video up, to show that for me personally been using Wagtail.
Found that the swivel movement made it restrictive when using.
So what we have done by using a PVC concaved shaped washer under the Wagtail disc.
As seen in video below.
Using this type of set up, which creates a 360 degree floating like motion when using in hand and on pole.
