Been working on the wedge of CSB's design and reached a head-scratcher. What material should I use on for the wedge so that it can be countersunk so the bolts are flush?

And what would be the best way to achieve the 45 degree angled sides to the wedge? I don't know if it can be done by bending a single part or simply have it in 3 parts and welded them together.



Oh and almost forgot this little render I did for a laugh
