Dear all, I have a epdm rubber lining on a s.g iron material but it keeps getting peeled off.What is the proper bonding used? Thanks in advance!

Dear all, I calculated the module & p.c.d of a worm & worm wheel for a Quarter turn gear box (used as a operator for butterfly valves)by starting with the torque required & using the lewis equation.Now,I require to calculate the handwheel shaft dia & the handwheel dia.Since the worm is hollow...

Dear all, I have been reading all your threads with interest.There is one problem I have faced in my company(& previous companies) We call it pin-stucking here in Asia.Well!The definition is very simple.Here goes:- If someone working with you in a company does not like you for some ediotic...
