Our local threshing show has a shingle mill that is needing a new blade. The blade is worn down to where the outside diameter is too small in comparison to the cast disk bolted to the underside of the blade. The cast disk measures 26" in diameter. We think it needs a 36" blade by measuring the general area available in the framework. A 38" blade could possibly work too but it looks to us like 36" is closer to the right size. Do any of you guys know if there is a certain ratio as to the diameter of the blade compared to the diameter of the underside cast disk? A fella who knows his saw blades looked at it and mentioned the blade in this saw is thicker in the center than on the outer diameter of the blade but he claims for no more than we will use it we can use a blade that is the same thickness all the way across the blade.
This guy said if we can find him a blade to work with he will put carbide teeth on it so it won't be a cheap blade but it should last us several lifetimes.
So again, do any of you guys know if there is a special ratio between the underside disk diameter and the outside diameter of the blade?
The underside of the blade
The name of the manufacturer. I don't know how old this mill is but I am pretty sure it is over 100 years.
