46trucker is right on about getting a cabinet shop to plane the wood. I took my wood, after 8 years to the cabinet maker who did my cabinets when I built houses. I measure the thickness before he planed it and and afterwards. DANG, you could hardly tell he had taken in off but yet the old finish was gone and the wood looked new.... the best part is he wouldn't take a dime from me for his 20 minutes of work.
Just make sure they don't get happy and cut waaaay to deep!!
