with some time and patients you can make one that will do what you are looking to do and grind limb lambs. its not as sexy as a big fancy one, and it takes me a hour to grind a lam stack but my homemade one is very accurate. i end up with about 0.003 variation in thickness across a 36" lam, which with the compressibility of the wood might just be me measuring. i would like to make a big belt fed one, but dont have anything currently to steal a conveyor of off, and haven't had the patients to sit down and machine rollers. I didn't have to machine any parts for my current one. i posted some pics of it on here a while back. don't rule out what you can create, or purchase something that doesn't fulfill all your current or future needs. .
