OK JB this is for you!! Its time to get started on this project. I know that there isn't Lot of DIY threads, But maybe we should add a DIYers Coulomb in the forums..... Hint,Hint!!! OK lets get started. I'm building JB a dual stage Cal reactor. 6" main chamber 4" secondary. First thing cutting the tubes to length using a chop-saw. Making ends flat for gluing, ( some day I'll make a jig to hold the tubes for this !) Sanding the ends down with 1200 grit for good adhesion Buffing the scuffs and scratches out before gluing. The layout for the base plate. Cutting out the base plate, access will be used for the sides and top plate (later on ). The router table with the baseplate. tubes and base plate ready for pump holes and edging. Thats about it for today, lots more to come stay tuned.
