I recommend all of the products at Turn Tex without reservation. Recently, we ordered a 14 inch cylindrical vacuum chamber in order to stabilize knife handle blanks. So far, we have used the equipment to stabilize stag horn, Osage Orange, Paduk, Walnut, Black Locust, Persimmon and figured Hickory. ALL of these materials stabilized perfectly following the directions found on-line at Turn Tex. The materials buff out very nice and the hardness has increased significantly without brittleness. Thanks Curtis!
