If you are looking to build a VDG for a good price you have come to the right spot. I have built these in all shapes and sizes for many different applications. Below you will find the link to download my 37 page manual on building a VDG that shows you how to build one from scratch using either a trip to Osh or a more sophisticated route with acrylic high speed rollers. Hope you enjoy and feel free to send in any questions. Thanks for looking!
