Bending the aluminum did not work out so well. Hiko how many layers of glass do you use? Other than the washers and the middle strap is there any need to use metal reinforcement?
I taped a piece of wood of the right size to suit the sheaves to the boom and covered it in plastic food wrap then laid two layers of glass cloth with a layer of carbon cloth between All wet out with resin
All was then covered with more plastic food wrap [We call it Gladwrap over here] and the wooden stick part was squeezed in my bench vice [with packers]and left to cure
I used the carbon cloth because I had some but I think four layers of normal
sheathing fibreglass cloth [ 12 ounce is it ? ] would be fine There is no metal reinforcement The aluminium you see is just to prevent the lower block becoming jammed between the other two when hauled down tight
The centre bolt clamps the set up to the boom in the selected place
I just use plastic sheaves from a boat shop with tube spacers in their centres and have done three like this now
They work pretty well Fit my cheapskate budget too
