Hi everyone, This is my first post to this wonderful mine of information, so lets start with an old favorite!
i've bought an old Sedgwick mb and have a few problems I hope someone may be able to help me with.
First off one of the knife wedges was damaged, I bought two new wedges from Sedgwick ( £90 + vat ) the new wedges need to be dimpled so I placed each wedge in the cutter block with a new knife, then wound up the five retaining Allen screws to mark the back of the wedges. Then took the wedges out and dot punched the centre of the Allen screw marks and drilled the dimples ( same size dimples as old wedges) with a pillar drill, so far all was well. The problems started when tightening up the Allen screws with everything in place, knife height set etc, as the screws started to grip they lifted up the cutter wedges, raising the leading edge above the cutter block. Has anyone else had problems fitting new wedges?
The second problem is when setting the knife height using the drag method, the wood moves at each end of the cutter block, but just kisses it at the centre of the cutter block, the tables don't seem to be warped when checking with a straight edge but I can't think of anything else that would cause this, am I missing anything ? ( wouldn't be the first time)
Thanks for any help in advance
Mark.
