I have a question about the shape of the wooden hood blocks. I always thought they were rectangular cubed shaped, with all sides parallel. I have pasted in a couple pictures of some original 28/29 style blocks, which is what I am concerned about below. Note the difference between the top edge of the blocks (end view) and the bottom edge. The top edge measures about .7" while the thinner end is any where from .04" to .05" narrower. I have several original blocks and they all have a certain degree of taper on them, some a little more than others. The thinner side is the on the two hole side which is on the outside. My question for someone that knows about these blocks, were the blocks really slightly tapered or was the taper due to wear on the wood over the years? I would think they were made with a taper as it seems wear that would cause the taper would be unlikely to be on all my original blocks. I can make the blocks easily in my shop, but I need to know the right dimensions.
