Jkeegan 18:32, 14 April 2011 (UTC) Hello! Adrian, what's the purpose of the hacksaw slot on the heater block? Is it just to compensate for expansion of the brass when it's heating up? Without threads, does the heater block hold on tightly? (I imagine it'd obviously depend on the size of the hole drilled, but in your prototype, is it easily slid out for maintenance, or tight?). On this page's discussion page I asked that too (sorry for repeating myself). On that page you mentioned you based your design on this one by Alain Mouette, and his pictures show what looks like a tightening bolt through the side with the slot. Just curious if you found the bolt unnecessary but the slot necessary, or just hadn't noticed the bolt, etc. Thanks!
