Spindle Sander Modification

I have been using my OSS lately working on parts for the secret project and it has come very obvious that the little 2" vac connection for a shop vac just doesnt cut it for real work.  so off it came and a little modification has been done and now it has a 4" port on it to allow connection to the dust collector system.

now I just need to work on a "Y" pipe to have some air flow above the table also...
