I have reviewed the attachments and email you sent regarding the vent/drain holes in the lower section of the UBSP post developed here at MwRSF.
I see no issues with increasing the size of the vent/drain hole to ¾” or 13/16” as need to facilitate better galvanization of the assembly. Additionally, That hole could be relocated on the base plate as needed as long as it was located on the interior of the base tube.
I will update the details in our latest bullnose testing to reflect a larger hole as well and place this note on the MwRSF Q&A site as well to help in disseminating the information to our states.
Thanks
