Here is my first attempt at making my own blocks. The wood is a piece of purpleheart a friend at work gave to me, and then some oak for contrast. The delrin pulley I turned on my drill press. The selvagee strop I made from #6 bank line that I bought from a place called The Thread Exchange I found online. I did lay up some rope grommets, but wanted to try out this selvagee strop after I read about it. The strop is basically 8 turns of the line in the size strop you want with marline hitching all around to hold it together. Really strong once it is all done up.
I have the rest of the blanks glued up already and the remainder of my blocks should go together a lot quicker than my prototype did.
