A quick bit of info first. Last night I made a trade. The gentleman was intersted in some of my music instruments and I wanted his Kurt vise(6"). He asked if there was anything else I needed as he was really keen on my m-audio venom keyboard. I told him the usual..."what ever you've got that your willing to throw in, you can never have enough tooling or materials." So, he brought the vise, some hot and cold rolled steel bar and round stock, a round bar of 6061, some files and parallells and these blocks that I have never seen as I never had a use for anything like them in my journies. I would love if someone here could enlighten me as to what they are, their application and maybe a general value(I think I did allright with just the vise so value is not that important). Much thanks.
