The standard pin spacing is 10” (254mm) or 9” (228mm) please check the spacing on your wheel heads, for whether they will fit.
Unfortunately, as standard they do not fit the spacing of the pins on the Cowley Double Drive ½HP Pottery Wheel. With care and skill, these can be drilled to fit, but you do this at your own risk.
