I have a 27 ton log splitter that handles 24" wood. Thing is, I do 16"-18" wood. If I let the piston retract all the way while I fetch the next billet I then have to wait for the piston to extend that empty 6 or 8 inches. Is there a way to stop the piston at an intermediate distance? I did drop a spacer in behind the wedge and the piston stops retracting when it hits it, probably due to some pressure limit. But is that a good thing to do? Is there some other way to affect the retract distance?
