Help with Clark Foam Hitachi Planer...

Hi everyone,

My name is Carlos I live in Costa Rica and have been surfing for about 13 years. I started shaping 8 years ago as a hobby using a Hitachi Stock planer, the surfing here has been increasing very fast so as the surfboard demand, because of this I decided to start making more surfboards. I just bought a new Clark Foam Hitachi planer which I guess it will help me shape faster mainly because of the depth adjustment…My question is regarding the depth adjustment knob, the planer comes with 3 different size pins (small, medium, large) to choose from…the problem is that it must be glued to what they call “wingnut” and after that it cannot be changed…which size pin would you recommend using?

Thanks for your help - PURA VIDA.
