Springs, U-Bolts & Hardware
This was a main concern of mine. From all the information I could gather the springs should be 1-3/8 inch’s wide. I was unable to locate any manufacture of springs of this size. 1-1/4 and 1-1/2 were available. I decided on going with the 1-1/4 springs and I would add an extra leaf.
The Stanley springs are unique in the shape from what is on the market. Each leaf would have to be re-cut and re-arched. The main spring ends would also have to be reworked to give it the shape of the Stanley end. To do this a thick washer was obtained from the spring supplier with the square hole already punched. These washers had to be welded to each side on both ends and added weld material and grinding was needed to get the desired shape.
I ordered six springs so as to have four extra long leafs and some spare leafs if I mess some up in reworking them.
Each leaf had tapered ends both in width and thickness and had to have about three inches cut of both ends and reshaped to a round radius and tapered in thickness.
Each leaf also had to be re-arched; this was done cold by hand using a template.
About six inch in from one end a tab was welded on the underside of each leaf and ground to a little knife edge protruding down. A corresponding groove was ground into the leaf directly under it. This keeps the leaf from moving off to one side. The early cars did not have the tabs on the sides of each leaf.
I still need to make new bolts with a larger radius on each end to match the original.
This work took a little over a month to complete. I would not want to do it again.
