nichrome wire instalation

Hello all

I want some guidelines on instaling the nichrome wire into the barrel and nozzle.
I'm building this hotend ( [www.a2aprinter.com]) and Iwould liketoknow recomendations on how to isolatethe the wire and if Ihave to wrap it all in the end of the barrel or if it's better to distribute.

I tryied to contact the seller but gave me this link with very little information.

I would appreciate any help or detailed photos or videos.

Thank you

I'm not familiar with that particular kit. I assume that the nichrome has an insulator of some sort and is not just bare wire. You generally want the melt zone as small as possible, so you should wrap it within the threads of the threaded rod about a dozen turns at most as close to the nozzle as possible. Try not to go over the threads so that you don't cut the insulation. Then wrap all of it in Kapton or Teflon tape to further insulate it and to retain the heat in the melt zone. You can also consider getting some fire cement or muffler cement to further encase it and protect it once you're done.

Makergear.com use nichrome wire, although with a ceramic covering, for their hot ends. You can check their web site for instructions on how to assemble what they call a heatercore.
