Well here is the result .
Paul (Shipwright ) thought it would be a good thing to build a sharpening jig for a variable pitch bandsaw blade that he uses, well here is the result .
After reading his comment the wheels started turning ,I had to come up with a different indexing device to locate each tooth individually relative to the grind stone .Then the Idea of doing the sharpening of the blade on the saw got my attention because of Loren’s comment .
Well here is what I came up with.
A simple sliding table on which a rotary tool is mounted clamped to the saw table and located by a hardwood strip in the mitre slot for easy set up .
Each tooth can be indexed individually by the locating spring as it engages in the gullet below the thooth to be ground .
The grinding wheel cutting depth is controlled by a bolt which stops the slide at the proper position .
The next tooth to be ground is simply moved into position by pulling the blade upward and the spring stop will snap into the gullet locating the next tooth .
To ensure minimal movement of the blade I have cut the blade into the base a short distance and provided a back rest via a screw .
I will leave it at that with the explanation and let the pictures do the talking ,any questions will be answered .
I hope this will solve Paul’s requirements and I met his challenge .
The big advantage I see in this jig is that I don’t have to remove the blade from the saw and sharpen it while under tension . Always unplug the saw from power when sharpening or doing maintenance !!!!!
