Need Help Choosing a Compact Table Saw

[nclemmons]

In my case, only two hole sizes.  The top and front holes are the same size and fit the Rockler hose I referenced above. 

In my case I measured with a Caliper and cut the holes with a CNC.  That let me do a press fit for easy removal of the box.

The over blade collection definitely helps with dust.  But you do need to plan for hose management of you are doing a wide rip on sheet goods so keep that in mind before you cut your hose.

Now that makes more sense. Thank you for the drawing! You're using this as crazy "Y" adapter because there are three different hose sizes involved. Is the over-blade dust collection effective on the DeWalt table saw?

If your expecting a clean table, it isn't going to happen.  I helps more so with airborne particles, bigger pieces still end up on the table depending on the material, type and size of the cut.

I used hose from a 1 1/2" kit purchased at Lowe's with one end fits over the blade guard fitting.  I used an adapter from some other kit I had that screw on to that size hose also.  I bushed down the 2 1/2" "Y" adapter with PVC pipe/fittings with a 1 degree tapered hole for a snug fit.  I used another PVC cap fitting with a 1 degree taper to cap the opening when not in use.  The other opening I used PVC pipe and nylon to bush down for a 1 1/4" hose on a Fein vacuum with another 1 degree tapered hole.  As mentioned above, I lose vacuum up at the blade guard for some reason but it's stronger at the "Y" fitting!
