I didn't know you were building a boat just like me. :lol: :lol: :lol: :lol: Sorry Chuck I just couldn't resist. You know how many times I did that too! :bang: --- Quote ---i have what might be a very dumb question but is there not fumes from melting the foam??? if so i hope you are wearing a mask or something to protect your lungs. chuck :wave: --- End quote --- The fumes are not that bad, I mean no big cloud. There are a few. A fan takes care of that. Bernd --- End quote --- :scratch: The real Stew or is there more than one |

Looks like I'm going to have to modify the cutter a bit. Also want to try SS wire. If it gets that cold I'm going for making an ice boat. :lol: Or I'll just stick with the steam engines and my model railroading and machine modds and ................ :D Bernd --- End quote --- Bernd I have seen that most people put a spring on one end of the nichrome wire to keep a uniform tension on the wire as it got hot and expanded. It can be a catch 22 situation. :bang: Too much or too little tension. Something else that would work is a pulley and weight system to keep tension on it. :doh: Cheers :beer: Don |

I already broke one wire after I shut the power off. :bang: That's the one mod I'll need to make. Think I'll add a pulley and weight. More even tension that way. Bernd |
