I'm sure it's going to turn out to be a happy accident ... that's how these things usually work :D

It's nice when you're able to dedicate a full day (or more) to ski building.

Norm Abram would be proud of that shirt! ;)

What kind of blade are you using? If you're able to re-saw cores that wide on that bandsaw, I should be able to use my profiling jig on mine (my bandsaw is almost the exact same size as yours, maybe slightly bigger)

Nice work, as always!

@twizz: The blade is: 2251mm long, 16mm width, 0.81 mm thick and 4 tpi (and suddenly the imperial measurement kicks in...:))
I don't know about the quality, it says bimetal M42, but it last for a while. I've used the previous band pretty much over a half year.
The motor on the bandsaw is 750w (1 hp), but with this blade it cuts the log quite easy.

I even filmed it! The most boring video on YT! :D

(It sounds terrible, but I didn't heard it until later, then I tuned the "wheel" but then the battery on the camera was empty...)

Wow, beautiful. Looks like it cuts very smoothly, thanks for the video! I need to spend some money on a decent blade I think.

i'd say get the least tpi possible. when resawing thick stock you want your blade teeth to transport as much wood as possible. keeps the blade cooler and cuts quicker. only downside is the rough finish.
i use a 32.0x1.0mm blade with 1.4 tpi to resaw snowboard cores.

Wow OAC - you're on it! Any chance of seeing the finish on the core after its been through the bandsaw?

Great work!

That's a quick way to make a core. So you were re-sawing right? Do you still use your bandsaw to profile the cores too?

Yes, resawing. The "bandsaw-core-profiler" is decommissioned for the moment. Not accurate enough. I'm doing the planer method with crib. I will post another "most boring ever" video later. Me planing a core. It's categorized as "Comedy". :D

damn, how do you guys manage to keep your cores down without gluing it to the crib?! are your rollers closer together?
we're using a huge Martin planer and it always wants to pull up the cores (snowboard). we even have to hold them down in the middle, the thickest part, so they don't come out too thin.
if we wouldn't hold them down with double sided sticky tape and hot glue, i'm pretty sure the planer would eat the whole thing!

I tack the corner of the tips down with hot glue. I used to use tape but glue holds better. Doesn't take much. I have a portable 12in Delta planer. The first few passes I take perhaps 1/32in off at most at a time. When the tip area gets thin, say 8-6mm I start taking off very little each pass... about 1/4 turn until I get down to 2-3 mm. This helps reduce chipping and tear out.
