Dewalt 611 Deflector and Dust Shoe

Post by vishnubob » Mon Feb 02, 2015 11:37 pm

The Dewalt 611 is a great router to use as the spindle for CNC machines, but it does have one drawback: the motor is air cooled, and this air is vented out the bottom of the motor housing. This blows all the chips and dust into the environment, making everything a big mess. I've designed a deflector plate to screw into the bottom of the router, deflecting the air upwards and away from the spindle. I've also added an optional mounting for a vacuum hose with a footprint that can accommodate a removable, magnetized dust shoe.

Nice!

I've been designing one very much like this, but machined out of a piece of HDPE. I'm interested to see your vacuum shoe and how it all works together!

Hi Folks! I've updated the design with the complete dust shoe. You can get the models and assembly instructions at Thingiverse:http://www.thingiverse.com/thing:663951.

Please share any feedback you might have.

How easy is it to access the collet and change the endmill when that is installed? I wasn't sure if it has to be removed/unscrewed every time or if it's thin enough that it's not really an issue.

It sure looks slick! Nice job.

Thanks for your feedback. The deflector plate/vacuum hose mount can remain bolted to the router during bit changes. The dust shoe is attached to the plate with magnets (similar to the Improbable Constructs design). Removing the dust shoe is simple and grants you easy access to the collet. I am using the ER20 collets from PreciseBits (http://bit.ly/1xi61VZ), so I can't verify this will work with other collets (such as a the default collet), but I would be surprised if it didn't work right off the bat. Along with sharing the model, I've also uploaded all the code that generated these models, so it should be straight forward to tweak the design.

Awesome printing one this weekend! Does it need to be ABS or will PLA work? I haven't ran my 611 for long so I don't know how hot it gets if it will melt the PLA.

I used ABS to print this, but I think PLA should be fine.

I assume you need to buy longer screws to hold the spindle lock button in place, right? Do you know what size they are?

Nevermind, I just read your instructions on Thingiverse. :)

Which Brush strip did you use for the shoe?

Is it hard to get the arrestor button assembly back in place? I'm a little bit scared to take out those screws.
