ok, to get the rebates milled..
Drawer Dividers, Rebate, was in the way.jpg
Had to move these out of the way...cauls were a might too close to my arms as they were going by..

Used the Craftsman3720 to mill a 3/8" wide by 1/4" deep rebate down the back of both case sides..had to mark which was Front and which was back..

Hardest part, was keeping the plane vertical..

And not take super thick shavings..

"Extra Crunchy"? hammer adjust for depth and laterals..

This was from ONE side...then, went back and did side #2...plane MIGHT need a sharpening after this Project is done?
