Ormy 0 Posted December 10, 2008 Hi chaps, I'm in the process of rebuilding a pair of dellorto 40s and one of the mixutre screws is stuck fast. Now as they're quite delicate I don't really fancy hammering the crap out of it to try and unstick it and I'm not sure if heat is a good idea either. Has anyone got any tips? I've tried hitting it (not all that hard mind) and a bit of WD but I really can't get the damn thing to turn. Thanks! Share this post Link to post Share on other sites
