Swix Scraper sharpener problem

post #1 of 4
Thread Starter 
Hey all, I searched and couldn't find anything this specific.  I ordered and recieved the swix pro plexi sharpener, the one with the longer file.  Mounted it, and as I was using it on an old triangle scraper, trying to find the best technique to sharpen, I noticed it  put an arch in the middle of my scraper and plexi filings were only near the ends of the file.  Anyone else have this problem and a possible solution?  BTW, there is also play when the file is in the guide, room to move up and down and back.  I shimmed it with thin cardboard, and still recieved the arch.  To remove the arch, I used a regular file until flat again, and tested on the swix, and still recieved an arch.

Try it with less pressure against the file (bottom of the L), and more pressure against the plastic backing (top of the L).    

That's a pretty agressive file; you really shouldn't need much pressure against the file at all, more on the order of "soft foot rub".

Looking at the bright side, your scraper can now be used to scrape wax from concave tips and tails......

As comprex suggests, you may be bending the file or rolling/rocking the scraper, creating the arch??? Did you use a true bar when you shimmed the file?

No, I did not use a true bar.  It happened whether it was shimmed or not.
