How to Stone Grind Skis by Peterson's Ski and Cycle

In this video we will explain the stone grind process for ski tuning. We tried to keep the video quick and informative but the tuning process is anything but quick. The initial pre-grind phase takes multiple passes for optimum results. Sharpening the edges is also a skill considering the degrees range from 1° to 4°. The bases have the same consideration from .5° to most commonly 1°. P-Tex is also a consideration when there are chunks of base material missing from the base creating divots or gouges. Polishing the edges is fairly straight forward to remove any burrs from the sharpening phase. Waxing can be done in multiple steps depending on the snow conditions and type of was desired. Again we wanted to keep it quick and engaging rather than long and winded. Any questions please visit our website at www.petersonsskiandcycle.com for contact information and hours.

They FULLY know what they are doing!!!!!!!!!!!!! The job done right, the only way!!!!!!!!!!!

Thanks to YT for suggesting this video. YT knew excactly what I was looking for😉🥳

Thanks for a valuable video great advice

The base pattern does NOT channel snow or water from the base. It does two things - it can break a vacuum created between the ski and snow, but more importantly it allows wax to penetrate the ptex base. Wax needs to be scraped off completely and the base pattern should re-emerge at the end of the waxing/buffing process. A small layer of wax will remain bonded to the PTex base.

Oh my god!! That ski looks gorgeous afterwards. Are you guys near JF/BB ?

[@PetersonsSkiCycle]

We are located next to WaWa in Blakeslee, Just 1 1/2 miles from the entrance to Jack Frost Mt. Stop by and give us a chance to give your skis some PSC love!

Does a grind also help protect the ski against water seeping in if it has got major scrapes? I got a used ski from Craigslist. I am debating getting just a wax or a grind / full tune. I just want my skis to last atleast one season; not super concerned about the performance.

[@PetersonsSkiCycle]

Any large scrapes and holes should be filled with P-Tex first to stop water seepage, then stone ground.

[@johnparchman753]

Large holes where you can see the lower layers and severe damage near the edges should be welded not just PTexed over. PTex alone will not stay in place and the hole will get worse. Base welding material is a combination of PTex and epoxy requiring a hot iron to melt and to work properly. As far as old skis go - I LOVE THEM. Skis get tossed into the sale bin LONG before they have lost their usefulness. People buy new skis because they get sucked into the marketing and the top graphics don't look as pretty. Keep the bases maintained, edges sharp and skis can last well over a decade.

What are you doing at 1:37? It is not wax or?

[@ericpeterson7328]

We use a cleaning bar to deburr the stone after dressing with a pattern.

[@brianfadness5306]

Does anyone know how much these usually cost

[@sk8187jc]

The skis are around $500. The machine he's using is $25,000+. The service is usually around $50

Just out of curiousity, what is the white stuff you're "dressing" the stone with before the passes, wax? If not, what is it? I wouldn't think it's wax, but something to keep the grit of the stone from getting clogged, what is it?

[@ericpeterson7328]

The white stuff is actually a thick polymer stone cleaning bar. After dressing the stone will have burrs which need to be removed. If the burrs aren't removed they will create 'nicks' in the pattern.

[@JamesDavis-kp4ll]

@@ericpeterson7328 , thanks for letting me know. That actually went through my mind after asking, it would make more sense that it might be some kind of plastic but I've never got to use one of these machines or be trained to, so I really didn't know for sure. That makes total sense about removing the burrs after the dressing process though, thanks! 👍

Hello, what is the model of the machine?
