A Knabe grand pinblock originally 1 3/4" thick. Sits on the shelf, with wood shims(thin), elevating the block/plate, to the proper level. Block ends are into the rim about 1/2 inch. The distance from the plate to the bottom of the flange is only 1 1/2 inches. So what is so stop me from using a 1 1/2" block and shimming the shelf the extra 1/4". It is screwed/glued down to the shelf away. If it is important to use a 1 3/4" block, why is it important? I ask as I have the 1 1/2" block material in stock, not 1 3/4" I am only considering if this may be an option, consulting with several experts that know better, including this list.
