scraper questions - Page 2

post #31 of 40
I knew Primoz wouldn't buy my heresy, but being a hot shot tech doesn't repeal basic laws of engineering.  Harder substances scratch softer ones period.  Your skis really don't know what type of scraper is being used, just that it is harder than the ptex. The key is having the metal (or plastic) scraper very smooth and not pressing too hard.
 
If you don't believe a plastic scraper can damage your base just as easily try this:

Take a sharp corner of a plastic scraper and dig that into a nice smooth ski.  Not pretty.  If you had done it on a window, there would be no damage and the scraper corner would be dulled.  Unfortunately, our skis are softer than glass.

The problem with metal scrapers is that they are ductile, and can easily have a burr.  The 600 grit sandpaper will remove that, but even then, when waxing racing skis which will actually see a race, I take the time to use a plastic scraper which is sharp enough to remove the wax without bearing down so hard it flattens the structure.  For big fat powder skis I use my smoothed metal scraper---thin enough to go through a thick pile of wax, never needs sharpening.

I actually do believe this. Afterall snow damages your base too. Take a look at structure right when you get skis back from stone grinding, and then after season.
So, yes I know plastic damages your base. But considering you have to scrape wax off the ski, you have two options... one is plastic scraper which damages your base less, or metal one, which does it a bit more. But neither of them is such, that you wouldn't need to worry about.

 I use a Dremel tool with a router table to sharpen my plastic scrapers. Works quickly and consistently. Avoids the "bow" if you put too much pressure using a file. Drywall screen works well with a Beast file holder as a guide to get a right angle. The SVST looks enticing. I own a SVST sidewall tool and number of SVST bevel guides--precision tools.

I have three scrapers that I use. A thin metal scraper, Thicker scraper (forgot the width, and a snowboard scraper).

I use my swix aluminum scraper for the first few passes to remove the bulk of the wax. I then remove the remaining wax that I can with my plastic scrapers. Then a brass brush to clean out the structure and a nylon brush to polish. Followed by a scotch brite pad.

I use the swix scraper sharpener as well. I monitor my scrapers (they become arched over time) I compare them to a tru bar. If you dont have a tru bar use a level. Levels are specific and tru. When my scraper becomes out of wack and not tru. I take it to the belt sander. Belt sander upside down in a vice and a few vice grips to hold on the the scraper safely.

I am currently using the FK/SKS sharpenenr shown. Works the best of any I have tried. (Still have the TOKO and SWIX shown above, they are in a drawer collecting dust!)

the advantage of the FK is that the blade is adjustable and the back-guide is long enough and high enough to allow you to keep your scraper square to the blade as you pass itthe scraper over the blade.
 

This is a very good sharpener.  I use it.

 I own some FK tools. Great tools, too. I guess I'll buy another gadget.

Steel rules.  It can be sharp.  It can be burred.  It can be smoothed.  It's all in your hands!

Just had my machinist buddy sharpen my steel scraper for the first time in about 10 years and it made me realize how I should be doing in  every year.  I only use my plastic scraper to clean edges and sidewalls.

That's all I use plastic for too!
