If you have a 18-25” lathe with 1″ post, these rests should fit. Examples include American Beauty, Powermatic 3520 A, B & C, Oneway 2436, Laguna 18/36 & 24/36, Harvey T60S and many others. NOTE: For the Oneway 20” lathes, only the Low Profile and 9” J-rest will fit. EXCEPTIONS: Some imports, notably the Grizzly 0766 and G0800 have very short banjos. You will need to special order extra-long post toolrests to fit these lathes. 25MM POST WARNING: Older Grizzly, Laguna and other imported lathes may use 25mm posts which are slightly smaller than 1”. THESE WILL NOT WORK. PLEASE MEASURE YOUR POSTS BEFORE ORDERING. FYI: 25mm = .984”, and 1” = 25.4mm.
