Project Day # 2 Foam Cutter V1

Welcome to the second Project day this weeks project is a diy foam cutter that I'm making for my sister who is into arts and crafts.

the parts

wood for the handle I used one 9inch piece and 1 6inch piece 

one battery holder I used a 4.5volt holder that takes three aa batteries 

two lengths of wire 

two crimp connecters

two bolts , six nuts and a washer

one length of Nichrome Wire

 

Step one 

I placed two of the nuts on a the six inch length of wood and marked out were I wanted the bolts to go .

Step 2

I drilled five holes into the six inch piece of wood two for the bolts and another to run the wires. finally one to join the two pieces of wood. 

Step 3

I joined the wooden pieces together with a screw 

Step 4

I attached the battery holder to the nine inch piece of wood with one screw.

Step 5

I the striped one end of the wires and soldered them to the battery holder followed by heat shrink to cover the connections.

Step 6

I fed the wires up to the top piece of wood and cut them to length and crimped on the two connecters .

Step 7

I then place a bolt through each connecter then tighten two of the bolts to hold it in place on the wood .

Step 8 

I joined the bolts with the Nichrome Wire  tightening the last bolt and wire to keep the wire in place .

here is the video on youtube

this project works really well it cuts through foam like a hot knife through butter I will be remaking this project again in the future and I will make some changes including add a switch and using longer bolts I was also thinking about making it run off a USB power pack

let me know what you think about it and if you have made something like this
