Love it Steve!! I may finally play with some metal this season.


For me I'd probably recess the metal in the core. Maybe a 2.5"wide strip down the center.

I'd like to cut out a mesh pattern like the Nordicas a couple years ago but I have to figure out the CNC part of that.

OK, so after playing with the drag knife a bit and doing a couple nights of research I have written a tutorial for those that want to use the Donek Excel utility and do not have CAM software that supports drag knives You can read about it on the Fusion 360 forum or you can access the tutorial at the...

I actually use the table to make my initial passes then clean up the sidewall down to clean edge, then the tilt base router to cut the final profile and add a slight step of 2.5-3mm above the edge. I also bevel the top edge of the sidewall with a tilt base to reduce chipping. It gives the sidewall a...

Just run the bearing along the edge of the ski. Start with it tiger than you want at first so you don't cut too deep. Make sure to clean up your edge so you are down to shiny metal then lower the bit to your final height. Be sure to keep your base flat on the table top. When you get close to the roc...

^^MM, agreed for sure on all of that! Yes I’ll have to use the macro also. Somehow it’s dropping the code to start the machine. I have to copy and paste it from the original file into the corners file. Probably because of this something is also off with my feed rate. Still working out some bugs ...

I emailed Donek Tools. They gave replied and they are willing to assist in working on a best practice tutorial for F360 to generate proper corner actions g-code for their drag knife based off some of the info I’ve pieced together from various sources.

Stay tuned!

Donek Drag knife best practices

So I recently got a hold of a Donek D2 drag knife. It's pretty sweet but I still have some things to figure out. I'm using Fusion 360 to set up the tool paths. F360 does not have native drag knife support so I have to use multiple steps to get the correct corner actions added to the code. I know the...

The only time I have seen this happen is if I did not put enough glue on the teeth. I generally put a small dab on every 3rd tooth.

CA glue can go bad with time, shelf life is generally about a year.

I’m in the design phase of a 5 point asymmetrical sidecut, rocker tip/tail similar to the K2 Marksman. I might have it ready to ski by New Years, but I have to get the last few customer pairs done first.

I always remember “warp out�. In case some don’t get this reference the warp fibers are the 0 deg and the weft fibers are the diagonal fibers. Placing the warp farther away from the core increases its effectiveness. The numbers quoted above about making things stiffer depending which way the f...

For what purpose?

If it is screen printing, regular epoxy is probably too runny and won't give you a sharp print.
