Just bore holes (about 1 inch will work) in the front of the cabinet equivalent in area to the DC hose and fresh air will draw thru cabinet and not only cool but enhance DC collection and efficiency .

true on the DC's efficiency but not so on the cooling..

attach a Temperature Sensor to the motor (or read w/ infrared) and take readings while working the motor...

see for yourself...

I used a Fluke DMM w/ a Temperature Probe...

nice...

what are you doing for cooling air for the motor???

Okay, I made a quick mock up of a enclosure to the lower part of the motor.    I left the back off so we can what is going on inside for the purpose of demonstration.  Made it 4 inches tall, more could be used, could go within 1 1/2 inches of the top if needs be.  With a air inlet opening up to 2 1/4 inches possible.  Now does it need one hole on each side or just one hole period?

 

2nd question:  Will enclosing the motor be an issue?

I'm the more is gooder crowd...

I vote for four sides...

a huge one in the bottom and you'll be less likely to pull in saw dust...

 

height...

what ever works and the motor's intake always stays in the vent irrespective of motor elevation....

Front is kinda crowded.  Would the opposite side (right side of cabinet) work?  Have more than enough room between the drawer slides to put a 1 inch or better hole. Top or bottom?  The air inlet is at bottom of router so I am thinking the bottom is better and it also already has a baffle set up to deflect the dust toward the DC port.

 

Anywhere will work but best is opposite side of cabinet from DC outflow or at least diagonal to it. The DC creates a vacum and must have a air supply and by having this flow across the router creates a cooling effect.

Got to say the temp deal is mote. Now for the DC : If the draw of air thru the router and mount ring is not equal to the amount drawn by the DC the Dc will not function efficiently and collect at peat performance.

agreed...

Having thought about what both of you have commented. I believe I have a best of both worlds application that will be one modification not several.  By installing a plate to go at the top of the motor and making that plate have a direct DC hose (inside the box) attached.  This gives better DC at almost the source while allowing more inside air to come below to the motor itself.

 

Of the many videos and article I watched concerning this build this issue was never addressed.  Some could say it is overkill and what does it matter. Others might say just buy something already made and be done with it.  For me it is important to have the equipment suit my needs, in this case a drawer that goes into a cabinet.  Not a typical plan for most.  I enjoy the planning and sometimes steps backwards to achieve a product that once completed will last a long time and serve me well.

 

Hopefully someone else will one day want to make something similar and read this thread and get something out of it.

 

Thanks for all the suggestions. Not done yet but finish work is around the corner.

There be a whole lot of wisdom and sharing on this Forum.

A thought on DC. Having air flow thru the cabinet will cool the router also. Collection will be better at the bottom and by placing a baffle across will give more even collection than a single hole

I noticed something in the picture you posted of your router...

swarf build up in the air intake vanes..

too much of that inside your router insulates against heat removal an it gets into places that are not good for the motor...

 

Maybe that is why it finally gave up the ghost.

Maybe a snorkel to the outside would have prolonged it's demise.

couldn't have hurt...

Had to stop on this project today, lights needed some upgrading of outlets to power them up.  I have draw out on paper a plan, how well that works requires some testing.

Okay so the lights went better than expected and I managed to make this mock up.  The back baffle remains stationary, the carriage rides up and down increasing or decreasing the size of the hole the DC has but cannot go below the baffle plate.  The baffle plate and the top carriage plate are angled at 8 degrees.  Combine that with the vibrations of the router and sawdust falls to the back where the hole is labeled.  Short bit of plumbing under the baffle plate to the DC outlet and this could be a solution.  Hole on other side of cabinet is marked and will supply fresh air to the bottom of the carriage.  Looking for guidance if I need one on the opposite side as well.  I put the top on sideways to give an idea of amount of space this baffle has.

 

Also got new mag switches in so I can start working on wiring this up as well.  Plan to make this plug in to a outlet in the back of the bench.  Two cords come out of box, one for power and one switched.

Yes , but it was mounted that way for over 20 years.

what did it die of???...

how about the DC pick up through the back of the box???
