I just acquired a new Excalibur overarm blade guard for my Grizzly 1023 cabinet saw. Here’s a link to the guard I’m talking about…

http://www.general.ca/images/machines/2_excalibur/2_machines/50-EXBC.png

The guard requires 40” to the right of the blade in order to bolt the boom arm to the saw. I have short fence rails and a cast-iron router table on the right side of the saw, so bolting the boom arm directly to the saw isn’t really going to work for me. And I don’t want to cut into the boom arm (make it shorter).

Looking for another way of mounting the boom arm. I’m thinking maybe I could build the boom arm into some kind of mobile cart. Then, when I need to use the router table on the right side of the saw, I can just wheel the Excalibur out of the way. Could this work? I’m guessing I’ll have to put some bricks in the bottom of the cart to counter the weight of the boom arm so the cart won’t tip over.

Thoughts?

That arm is fairly heavy. Cantilevered out as it is, you would need a very heavy cart base to keep it up right.

However, once you get the bracket attached to the saw, the over arm part easily lifts on/off via two pivots. Assuming the weight isn’t an issue and you have some place to put it. No need for a cart.

As far as distance to blade, I’d make a permanent extension to the table saw/router wing to get the mounting point at a distance from the blade that works. And just lift the arm on/off as necessary.

Hi Jason,
Several years ago I purchased the blade guard only and rigged it up to hang from a pivoting arm attached to the floor joists above. It worked well enough but I occasionally struck the arm with a board and it also blocked a lot of light from the cutting area.
In addition to your own idea of a cart with counter weights you could have some type of cable tether from the ceiling to help support the arm over your cutting area..
Hope you have some success soon. Marc

Build something like this, or use a steel pipe with a square plate bolted to the floor. Just set the new pipe into it or over it whichever works best. You would have to incorporate a tee into it somewhere.

One of the most important things you can do with that is, toss the pathetic push stick on top and replace it with a shoe.

I’m not sure I understand why a router insert and such are a problem. The exact same unit, below, has been working for me for about ten years.

I like alittleoff’s approach, but you would still have to attach it to the table. You WILL have boards hitting the guard and lifting and pushing it.

I think you’ll have a helluva time getting a mobile cart heavy enough to hold that thing. I like that tripod design, that might be a choice.
