<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Grin... DUH !!!! And I had to ask.... Didnt even look twice at my own conversion from inches to mm.  (2 inches). I knew there had to be something simple I was missing...  Thanks. Now we can get into whether or not his 2 inches was a good call... :)  yes ?? Cheers RicB "David M. Porritt" wrote  Well, he said the bore would have to be 2-inches (50.8mm).  If the stack were raised 2.8mm, that would allow a 48mm bore.  As I mentioned, it could screw up everything else too, but I thought it worth looking at as a possibility (I have seen actions screwed up in all kinds of ways).  I know one factory that used to keep several different sized blocks for mounting the stack depending on the string height. dave  *********** REPLY SEPARATOR *********** On 8/20/2003 at 5:31 PM Richard Brekne wrote: <blockquote style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid">Grin... Ok David P... you got me scratching my head here... How do you come up with a stack raise of 2.8 mm to achieve 0 rake, 48 mm bore and no overcentering based on the info Bob sent in ?...
