[AT] Shop question

[Cecil R Bearden]

Could you use a round floor plate flange with a close nipple on each 
side of the metal.  If you were concerned about it scraping where it 
went through the metal, you could put a piece of plastic pipe for a 
bushing.  The floor plates will seal with silicone or a gasket.
