| The white chuck in the top photo is a 3" to 4" PVC adapter
coupler mounted on a Giffin grip. There are a variety of adapters from
1/2" to 6" in diameter. Regular couplers (same size on both ends) are not as tall. As an example, a 4" coupler is about half the height as the one in the photo. I have a collection of different sizes and just pick the one I need. If you are trimming something with a long stem or neck all you need to do is to add some PVC pipe to clear the wheel head. To center the pot I slowly spin the wheel and use my pointer finger, watching how close the pot is to my finger. This makes it easier to spot an off-center pot. I also have a small plastic level that I keep around to aid in leveling if needed. The foam between the coupler and the pot is the foam that comes in the box of Orton cones. I use jar lids to hold the pot in place while I trim. I use a little downward pressure letting the cap spin under my index finger to hold the pot down. |
