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

most of thier models are boly toghether? yours looks to be a welded table
jim

I can take a close shot of it for you, but its welded and bolted,its extremely heavy as we had to bring it in on its side ,took 4 of us to flip it.
I cannot lift one end,and right now i have it a 1/2off the floor ,found it was jerking too much during routing (is on lockable casters)
I feel its well built

probably want to do with out the casters

these things have a lot of inertia
jim

this might give you an idea ,it was before i took it off the casters

ill post some pis of mine tonight
