I have manufactured this dust collector which works very well connected to a 3hp oneida dust collector via a 4 inch feed .
Mind you re-surfacing the table top will tell the truth as thats when the mdf dust flies.
I included the cannon carving as I was quite pleased with the results.
I also have a short run showing the machine in action
