Your base edge filing method

post #1 of 11
Thread Starter 
Hi,

I'm curious how you guys are setting your angle on your base edges: specifically, do you rough in the angle with a coarse bastard file (or panser), then go to a second cut file, then finish it with a smooth file and follow up with diamond stone polish?

Or is this getting a little too involved? Just a medium coarse bastard (say, 14 tpcm) to set the angle, and then go directly to the diamond stone finish?

I've always had the shop set my angles in the past, but I'd like to start doing it myself this year (when needed). Just wondering what people find works for them.

Thanks.

I use an ice-cut file to set the angle then go to 220 and 400 grit diamond stones to clean up and polish.

Which ice-cut do you use? I've got the 'second cut' ice-cut file, which I think is about 16 tpcm, which seems like it would be coarse enough for an initial setting, but maybe I'm on crack. Not sure if I should buy a coarser file or if that one should be sufficient.

I believe it's a Hard Chrome Bastard...This one...

Most of us won't change the base bevel. I just use a stone (or diamond) in a 1° guide to remove any pushed-up damage to the edge. I leave the base bevel work to the shop with their ceramic disc edge grinder. I do file the side edges as needed, then stone smooth.

Ice-Cut, then diamond stones. It's pretty much the same thing a good shop will do

I use either a 6" Holmenkol non-chrome 18-TPC very fine file Race file or a 7" Toko No 5(Made by Vallorbe) 20 TPC also non-chrome and a fairly hard gummi stone as described below. . A Panzer or Coarse bastard is too aggressive for base beveling.

I only use those on the side edge.

By Dave Peszek on setting Base bevel. Holmenkol. product Mgr.

Always use your sharpest, finest file (be sure to check it for flatness before using it!). It only takes a few passes to set the bevel – avoid the trap of over beveling, leaning on the file to get it to keep cutting, and bending the file. I like to use the two thumbs approach – I press the file straight down with both thumbs, with my left thumb over the center of the base and my right thumb directly over the edge, while pulling back smoothly. When you are done, you can polish the base edge by holding a gummi block directly over the base edge, applying strong pressure, and working the gummi block back and forth.

My base bevel method is sending skis here when they need a base grind...

I let the shop set the base angle once in a while. In general I freehand with 200 and 600 diamond stones to knock down minor damage, maintain and polish, then do the side edges with a fixed angle guide. Major damage gets beaten into shape with an alu-oxide stone.

In the odd cases when I've actually set the base myself I've used a Swix base edge guide - "ice cut" 2nd cut file, 200 and 600 diamonds.
