I wanted to buy a cordless rope hot cutter for the many polyester ropes on my sailing boat that are messy to seal. I was astounded at the price of about £200 (270$) so your DIY rope cutter will be ideal for me as an inveterate modifier and shoestring sailor. Thanks for your excellent design and test. You have saved me a heap of beer money.

My daughter and I were making a kayak that was covered with a nylon fabric that was a nightmare to cut because it was fraying so badly. I used this tool and it cut through the fabric like butter!

Seems like the button contacts should go on the same side as the battery. Then you could print a small cover for that entire side and run the wires out a small hole on top of the cover to the cutting wire. The cover + the handle will give a better hand hold on the entire system.

Two particular things I loved about this video: 1) "I thought that would be a really complicated way to do a simple task....and so that's right up my alley, right?", 2) it demonstrates a typical engineering process, with investigation, problems encountered and corrections rather than edited out in post production.

Of course I optimistically thought it would be a cake walk.

Thank you for taking the time to pass along your fine process and good results. I am making one today with an led added that will come on when button pushed to illuminate the work as it happens. I watched many videos but only needed yours.

Wonderful!

Hi Rob, I want to build one of these for our sailing club but I'm struggling to get the 3.7v battery you used but can easily source a 9v version. My question is what changes would I need to make to account for the increased voltage. Was thinking of increasing the wire gauge? Any help appreciated.

On your original prototype, would not a heavier gauge wire have accomplished the same thing?

What an awesome idea! How well has the battery held up to this heavy load?

The battery works great, the plastic where the wire is fastened has deformed somewhat. I was making a kayak that had a polyester skin. Using scissors was causing the fabric to fray but this tool worked great and melted the edge to stop the fraying!

hey, what household items can i find nichrome wires
