Sherline-The rocker riser toolpost (P/N 1288) and 3/8" riser toolpost (P/N 1289) bring tools to the proper height for use with the riser block on the lathe. Each also has a 3/8" round hole for insert tool holders. The rocker toolpost allows 1/4" cutting tools to be adjusted so their cutting tip is exactly on the lathe's centerline.
