The idee is a 172 wide and stiff allmountain board.
Tip/tail:324
waist: 269
fircore, no sidewalls, p-tex tipspacers
Looked around in the stack of wood at my dads farm and found some slowgrown fir planks with allmost no knots. they were 22mm so alot of wood to remove...
Cut strips and planed the edges with a handheld planer turned upside down
glued and clamped
planed it down to 9mm
made rails for the router, threw away 3 pairs before I was happy its hard to cut straight with a jigsaw...
the tail came out great, started with the nose all exided, thinking this is easy. Working fast untill I hit something hard... the cheep f***ing router did'nt keep the depth, I was cutting in the worksurface.

Kicking and screaming for a while.
Nothing more to do then scramble in the woodpile again.
This time i found spruce and birch.
Starting all over but with a different idee of core
Birch on the edges and two strips in the middle to hold the inserts.
working on a farm in time of harvest, just waiting for a rainy day...
