Bill_S Posted February 17, 2015 Share Posted February 17, 2015 For a couple of years now, I've thought of how useful an abrasive thread would be at times. I did some searching last night, and I found some! This abrasive on this stuff is labeled as "extra fine" - although it's advertised as 220 grit. Silicon carbide impregnated on a 0.018 inch (.46 mm) diameter cord. I ordered some off eBay - with shipping factored in, it was cheaper than going through the manufacturer. If anyone is interested, I'll let you know how it works out. Link to comment Share on other sites More sharing options...

LSP_Kevin Posted February 18, 2015 Share Posted February 18, 2015 Great concept! I'd heard Gerald Voight talk about using cotton thread as a fine saw for removing parts and cutting plastic, but this stuff could potentially be even more effective. Please do report back!

Kev I hadn't thought of using it as a saw, Kev. Maybe I'll experiment on some old clear parts. It's supposed to be delivered by the weekend; I'll you you posted!

thierry laurent Posted February 18, 2015 Share Posted February 18, 2015 FYI, this technique is known for ages by car modellers to cut a door out of the body of a car without damaging it, nor the body! Bill_S 1 Link to comment Share on other sites More sharing options...
Bill_S Posted February 28, 2015 Author Share Posted February 28, 2015 I did some testing tonight. This product was advertised as .018 inch diameter; what I got was slightly oversized (.0206 inches). I can't tell you what the cord material is, but it doesn't melt - it burns. I attempted to cut a spare windscreen off the sprue holding the cord in my hands. I succeeded in removing most of the abrasive. I cut another section (it cuts easily with cheap scissors) and tied knots at each end. I then used some old drafting dividers to make a "saw". Used this way, it cut pretty easily through the plastic. Getting this stuff into small places should be fairly simple; the stuff (when new) is relatively stiff. For polishing/sanding it will take a light touch. I'll have to play some more to really figure out if it was worth the money. brahman104 and Out2gtcha 2 Link to comment Share on other sites More sharing options...
