craig10 Posted January 4, 2011 Report Share Posted January 4, 2011 Hi all, Just wondering what thickness the liner spigot has on the 150 kit. If it fits without boring the cases then it must be thin as a 63mm bore with the TL's 49.5mm stroke gives about 154cc. I measured the casing bore on an XL to be 63.6mm. Any ideas what the bore and the outside spigot size are on the kits? Do you have to bore the cases? Thanks, Craig Quote Link to comment Share on other sites More sharing options...

craig10 Posted January 6, 2011 Author Report Share Posted January 6, 2011 Thanks for that Max, I actually meant the 'Sammy Miller' 150 kit as opposed to boring your own Quote Link to comment Share on other sites More sharing options...

craig10 Posted January 9, 2011 Author Report Share Posted January 9, 2011 Yes, thanks Ross. I've bored out a set of XL casings to take a 185 barrel but run into troubles with the oil gallery, http://www.thumpertalk.com/forum/showthread.php?t=945828 Not insurmountable, I'll take it down to Sammy that advertises in the SCRMC mag, he does ally welding day in day out. Failing that I might put an external oil feed on it and blank off the gallery. I was going to use epoxy steel but I'm not a great fan of it, Craig Quote Link to comment Share on other sites More sharing options...
