Hi All,
The modification of wood sliders will be poor in hard snow, ice conditions. I own a Hus-Ski 444 snowmachine with the oak sliders and needs good lubrication .The one thing I did was to drill a series of holes in the bottom of the slider, snow packs in them and melts out when you are in low snow area.
The wood framing in the pics is really good, note how well the top side frame board , and the top roof frame board fits together. The side board would be cut out , and the top roof piece steamed to fit. Looks like ash wood .
