Hi everyone
After trying to cut foam with the hobby knife and getting very uneven surface. decided to build
a hotwire cutter.
Have an old computer table, made a small hole in the centre aand at the top
Attached the bottom string with simple screw and for the top connecter
used a J Hook used for holding corrugated metal sheets in making roof
Used a Small spring as a tensioner for when the wire gets hot and expands
a 12V 3Amps power adapter which was lying in the house was used , you can also use a 12V 2Amps
The nickle crome string is a guitar wire No. 2
Any comments on how to make it better will be highly appreciated
Thanks
Subir
