I am waiting on a v band flange to show up, get it on the lathe to modify a bit - then I have a few more welds to finish up. After that everything is getting powder coated black.
That is what I was thinking when I build mine. My irate mount already has the 45mm gate so It would me nice to just use that for the secondary. It would be border line thought a 50mm or 60mm would be better suited.
