[QUOTE="Clark, post: 247400, member: 6600"] I know that when they bond things in electronics, they know the expansion range of each piece. They know what is bonding them together and it's range of elasticity. The kinds of problems they have are: a) The bonding material want to be thin for heat, but thick for stretching. b) The bonding material choices have thermal conductivity at the expense of elasticity, i.e. the rubbery stuff is like an insulator. c) You would like to have big parts to get something done, but may be only able to have short parts. If that is a problem over .1" with electronics, imagine the problem over 24" with a barrel. And anything that warps the barrel with heat, wrecks accuracy. [/QUOTE]
