Thread: Lost...

Tony,

You might be looking for my thread in Dust Extraction https://www.woodworkforums.com/f200/clearvue-installation-auto-blast-gates-232682

At post #47 I move onto my design for an SCMS cabinet. I've made a few improvements since it was completed.

my man.. not only the SCMS but also the Kreg fence as well. You are amazing....

now we get some more jobs finished.

care to share your improvements.

Sure! Give me a day or so to take some pics. I'll post them onto the original thread.

There's no need for wheels.
As long as the extraction hood is appropriately shaped and made out of something slippery like acrylic then if the front of the hood is sloped forward the workpiece should force the hood to ride up and over. The front of the hood should slope forward anyway since the extraction hose for it should be as far forward as possible. Most hoods have the hose location too far back which makes fine dust extraction less efficient.

The problem for most people is to arrange a fixture to enable the hood to raise and lower easily and stay in close contact with the workpiece
The simplest arrangement is a pivot point say at point "P" but this turning arrangement does allow the hood to sit flat on top of the work piece so does not seal the hood up against the work.

Two pivots points will enable this but the hood needs to be well made otherwise it becomes a tad sloppy and moves around.

A better arrangement is a parallel pair of arms that raises and lowers the hood while keeping it level.
John Samuel has one in his thread on 150 mm dust ports that should not be braying most woodworkers abilities.

Hey Tony,

I've posted the updates on the other thread.
