R2720 is a good sander with one failing, you can't easily hook a vacuum up to
it. The collection bags on any belt sander I've ever seen or used always do a less
than adequate job of dust collection compared to a vacuum setup. A vacuum hose makes
the tool a little more unwieldy but the benefits far outweigh the problems.
In order to fix this issue with the R2720 I decided to try and hook it up to my shop vac which has an automatic turn on feature when the tool in use is plugged into it.
|I started by removing the
bag from the fitting inside it which is a twist-lock connection to the sander body.
Once this was removed I decided that the twist-lock feature was nice to have and instead
of replication one, I chose to use the OEM as the base for a hose adapter.
To get the 90 degree bend for a good hose orientation I tried a 1.5" PVC pipe elbow which was a close fit. With a minimum of sanding it went into the twist lock section. Instead of relying on a glued connection I tapped a couple of small 4-40 screws through the parts to hold them in place.
A little sanding with a Dremel tool on the elbow outlet produced the appropriate snug fit required for the shop vac hose end.
|Although the modification isn't as pretty as an OEM part, it does work very well and only required a few minutes worth of effort to accomplish, well worth the time.|
