A Length Stop System for a RAS

Furnished content.
(from WoodNet.net)


If you have a typical RAS, the table is not very wide. On my larger Dewalt GA, it'sonly 16 - 18" on the left side of the blade. It's wider on the right side but that side is unsuitable for a length stop system, at least for short parts, because there's no way to hold the stock with your handwhen the sawhead is pulled out to cut it.I can't add a table extension on this saw because of where it sits in my shop, so I needed a length stop system that can be added only when needed and then removed.

I came up with a simple approach. It uses a piece of 1/2" wide stock on top of which I applied aRto L tape measure. That piece of stock fits into a dado cut into the top of the fence. Friction holds it in place, but it can be slid as needed to align with the edge of the kerf in the fence





A simple wooden block with a thumb screw is locked to the fence for whatever length part is needed. With the fence in its normal position there is about 16 - 18" to the left of the blade. When longer parts need to be cut, the fence is pulled to the left and the tape is slid to the new kerf position.



With this tape I cancut parts up to 36" long. A longer fence and tape could be used for even longer parts. The portion of fence missing to the right of the blade can be replaced with another piece of stock if more support is needed on the right side.
