Core Profiling

Post by AndrewT »

Ok I really like the site it's really informative. One thing I dont understand though is how you do the core profiling. Is there a specific tool you need for it? and how is it done?
I would really appreciate some help on this.

Welcome to the site Andrew!

You do need a special tool for core profiling - a router. By using a router along with a jig you can profile your skis relatively easily.

just make the surface on which you profile on is very, very flat

You mean the surface that the wood core goes on?

are any of you still using the thickness planer method of core profiling? I wondered if the taper to 0" was a problem...

i still use the thickness planer as my profiling method. the planing to 0" is a a little problem because the wood starts to blow out, but i tend to cut away a lot of the tip and tail sections for the tipspacers anyway so it doesn't matter too much.

big Kam and Kelvin have a good idea of combining both the planer and router methods to profile the cores. first use the planer to take off the majority of the wood. it's much faster and less wear on the router. then you set up your router jig and finish off the core to get cleaner tip/tail profiles.

That makes sense. To be honest I was trying to avoid building the profiling jig because I am so excited to get a pair in the press that I didn't want to spend the time on the jig.

I now know that it will be a necessary tool and will endeavor to build one asap.

Any revisions on the original plans for the router profiling jig?

Thanks for all of your feed back on this subject. Plotting this project has been the highlight of my summer.

nothing to kill summer time like ski building.

no updates on my part for the router profiling jig. it's pretty simple and works really well. i'm going to build a new one pretty soon, but for the base of the jig I'll use a bunch of 2x3's glued together and then put it into my planer. hopefully this will create a super sturdy and flat surface for the blank wood core.

i would spend some time and make your router jig carefully, however. if everything's cut accurately and works properly then profiling will be less of a pain.

i'm sure you can profile a core with that. it may take a lot more time but it should do the job. i've heard of some snowboard companies using handheld planers (back in the old days) to profile their cores. and i remember some kid profiled his cores with a hammer and chisel. so if they can do it you can do it. just go slow with the planer and take a lot of measurements.

A belt sander would be better for hand tools.
