Hot-Wire Foamcutter (Battery Powered)

Step 6Assembling / Using

Assembling / Using
Time to put it all together.

1.I glued the battery holder close to the top corner (granted this did cut down on my cutting freedom so relocating this may be a good idea)

2.Attach the bent rod using the two 5mm x 30mm bolts to the two holes drilled into the top right of the board.

3.Run the long wire beneath the board to the hole in the middle of the board. Run one of the 3mm x 20mm bolts through one of the washers at the end of your hot wire length. Then feed this bolt through the hole, attaching the wire to the bottom and fixing it all in place with a nut.

4.Taking the free washer end of the hot wire, run the remaining 3mm x 20mm bolt through it. Next run this through the end loop in the bent rod, using the elasticity of the rod to pull it taught.

5.Use, attach the short length of wire to the 5mm x 30mm bolt and cut away.

Hoping that was helpful if anything is unclear (my wording can be rather cryptic at times) please feel free to ask any questions in the comments and I'll do my best to answer them.

How do you go about getting these from Keyelco.com for free? How is it they don't make you buy them, or do you just request a single sample? Thx!

yes, you just go to the website, and there should be an area that says "free samples" Once you find what you want you need to put the part number in the box and then fill out the shipping info, then they send it to you :) I've only requested 2 samples at a time but i think you could go as high as 4 if you want.
