Excellent advice Ron. Make darn sure the pin block is indeed to low before you start chopping away at it. Look closely at the action to see if you can get it to work well without all the mess and stress of removing the pinblock. 1/4 inch below the stretcher is not a huge distance, and certainly not unheard of. I run into Petrofs all the time that have this condition without drop screws neccessarilly draging on the underside of the pinblock. I have even seen a few Yamaha C3's come out like this. How far up are the drop screws from the surface of the flanges ? And is it easy or difficult to pull the action in and out relative to existing and/or proper hammer height ?
