I noticed the approximately 45 degree angled cut into the main caps, so do the blocks webs also have the 45 degree cast into it, or is it a hollow space. If it is cast into it, wouldn't that be better support for the main caps, instead of having a 90 degree angle that would cause stress/cracking at the webs. In reality more support for the webs.



there's an open hole where the cap is cut to 45. no support to the block in that area.
