Could it vary by store? My local Home Depot did not carry 8-3 by the foot. They did carry 8-4 and 6-4 by the foot which is fine, I could of just not used 1 conductor/wire. It says they have to spec ...

Ok, credit to my brother who helped me find this 8-3 cable at Menards, pretty flexible so it should store easy and it's rated for 40A. It's in the extension cable section, where they have supplies for ...

Hi Doug,

No, there isn't a problem other than being able to shrink my platen/sheet size. I was checking some dangle angles against the general specs in the protoform plans for my mold height/widt ...

Yes, I've read that thread, and from what I gather, using a hardibacker oven is somewhat acceptable if used in a plastic over heater configuration, or minimal hobby uses. Being that mine would be ove ...
