I saw this over at Homemade tools (originally posted by "Rustyiron" on tractorbynet.com http://www.tractorbynet.com/forums/b...ml#post3156521). It is not my original idea.OK, now we got the legalities out of the way here is my interpretation on Rustyiron's "Spiral Wrap" cutter.I need to protect the pedal wires on my TIG as they cross the walkway when in use. I also don't like the idea of them being pierced by sharp metal.After seeing the post for the "Spiral Wrap Cutter" I decided that I would build it because I use spiral wrap a lot for wiring,control cable, and hose protection It is expensive to buy, not locally available, and comes in limited lengths and materials.To start, I needed to make a couple of small plates to serve as the blade clamps and as a way to clamp the tool in the vise for use. I posted that here as an example of "Slots and Elongated Holes" http://weldingweb.com/vbb/showthread.php?t=281791 Not shown in these pics are the four 10/32 threaded holes you will see in later pics of this post. Drill them now as it is easier.Other than the 20* angle of the tube to plate ALL measurements were strictly arbitrary and conform to the TLAR (that looks about right) engineering standards.Once the plates were cut I brazed one of them to the tube at a 20* angle to the tube which will set the knife angle for the spiral cut. The 1/4"x20 nut is also brazed on to hold the small tube adapter (more about that later). I brazed it together because 1. Argon is in short supply this weekend and 2. I got a bunch of old unknown alloy brazing rod and a can of flux for next to nothing at an estate sale.Now that the angle is established on the tube I hack sawed a slot parallel to the plate for the cutter blade (a utility knife blade in my version) to pass through the tubing. Keep the slot flush to the plate and cut it wide enough for the blade to pass all the way into the tubing as you will need the adjustability for smaller sizes of spiral wrap.The blade in position before adding the clamp plate. Note the four 10/32 tapped holes that hold it all together.All together and ready for testing.Continued in the next post. Please wait for the interweb to come to a full and complete stop before commencing with the flaming.RogerOld, Tired, and GRUMPYSalesman will call, Batteries not included, Assembly is required, and FREE ADVICE IS WORTH EXACTLY WHAT YOU PAY FOR IT!Dial Arc 250HFThunderbolt 225 AC/DCAssorted A/O torches
Reply:PART TWO:All together and clamped up for the maiden voyage. The small tube protruding from the end is a piece of tubing to adapt the cutter for small diameter use. You can see the bolt that holds it in place. For larger diameter spiral tubing you will leave this out and remove the bolt.SUCCESS!A look at the business end of the operation.Once the material is inserted you turn it clockwise and hold a bit of pressure against the blade to establish the cut and the the blade will guide the cut in a consistent spiral as the tubing is thread through the cutter.Another fine project from the bewildered minds at the R&D Lab of T&E Technology.LET THE FLAMING COMMENCE!

Reply:No flaming. That's downright awesome. I like the use of the razor blade. That stuff is crazy expensive the larger it gets. Something like this has been on my build list for a while.

Reply:Looks good to me! You had fun putting it together so if it also works, that's just a bonus.Mikel

Reply:Love the tool Great job!But this stuff seems pretty cheap to me.http://www.mcmaster.com/#spiral-bundling-wrap/=n4ucbl
Reply:what he said above.thats what i used, works fine and didnt seem expensive to me

Reply:FANTASTIC BUILD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!That crap is way too expensive for my tasteIf it goes on a truck it's overpriced, stinikin parts placesBuy the stuff that's for real, about maybe 2", and it's pricey.

Reply:That is a pretty cool little tool. I used to work in injection molding, and we used that wrap stuff for all the mold cooling lines and works pretty good. A few time we needed a bunch of that stuff, and sure enough said it like it was, store is closed, all out, and needed the job to be finished, we however made due with what ever we had, but that is the tool we needed. Nice work.

Reply:Got rained out of finishing the yard farming this morning so I spent some time Spiral wrapping the TIG throttle cables.Turned out just the way I wanted. The cables are still flexible enough to be easily wound up and hung on the storage hanger and easily moved around the shop as needed. No more rolling my chair over a wire or tripping over two separate wires laying across the path.
