Base Bevel File Guide

Fully printable base bevel guides provided by a snowboarder and experienced tuner.

Made with Holmenkol files and diamond stones in mind, so max 25mm wide files. Will add wider variants if theres a need for it.

Printing settings:

I'd recommend 4 walls with 100% infill an 0.12 layer lines. I got the best and very clean results printing the part standing but your support settings should be dialed in to print this way.

Be sure to debur the rough edges of the printed model so you dont scratch your ski's or board by accident.

Printed with matte PETG.

The bolt used was made by Cam Chaney, you can find the original here together with his awesome side bevel guides. https://www.printables.com/model/854102-ski-edge-sharpening-guide

How to use:

Check the angle of your base bevel by marking the base edge with a sharpie. Run a shallow guide with a coarse diamondstone or fine file (18 or 16 cut file) along the edge of the board with even pressure. The guide that takes the sharpie completely away is your factory base bevel. (Start with a shallow guide, since this takes  almost no material away if your board is set at a bigger angle.)

If you do choose to alter the base edge bevel, here is a quick insight on angles:

Shallow bevels (05°-0.7°) are used for very experienced riders only but provide the sharpest and precise edge. -> If you doubt you need this angle, you probaly wont and should settle for a 1°.

The bigger the base bevel the less 'catchy' your board will feel. So for beginners I would recommend a base bevel of 1.5°. A bigger base bevel also wants to roll on edge (initiate the turn) easier.

Park rats want to use big base angles (>2°) so they wont catch edges on features or dull the edge completely (INREVERSEABLE!!)

Disclaimer: Base angle altering is not for beginners. Use this tool at your own risk, I'm not responsible for any damage that comes from using or misusing these guides. I do not recommend using this at all if you don't know how to tune ski's/snowboards already.
