This is actually my first post, been reading LJ’s for 4 years or so just never had anything to contribute.

I am looking into either buying or DIY ceiling mounted table saw blade guards and had an idea while researching the topic. I could use a PC monitor arm mount like the one listed here. My though process was that it could be moved easily when you need to swap saw blades and such.

What does everyone think? My main concern is the load on the arm. Will it lose the ability to hold over time? I have a different set that holds dual monitors at home and the monitors are 24” with speakers so they are not exactly light.

Why not save yourself the trouble and just get an overarm guard?

Cheers,

It will not loose the ability, it will never have it. A blade guard must be strong enough to stop your hand from moving into the blade area. I somehow doubt that monitor holder i capable of that. It may even give you a false sense of security that you have some protection while you have none.

If you’re going to build an overarm guard, might as well build it with dust collection ability.

I actually always wondered how reliable overarm bladeguards are. When the bladeguard is installed on a spliltter the whole construction is very rigid as the the splitter is very short so the flex does not translate into excessive bladeguard movement. With the long arm of the overarm blade guard holder it is bound to flex with much higher amplitude. Can it touch or even overlap the blade ?

Blade guards are generally useless, that’s why most people remove them. Their main purpose is a legal defense against people who choose to be unsafe. That’s why it’s a good idea to include dust collection, then it becomes useful.

Sorry guys, to clarify I am in a similar school of though as Rick. This rig would be completely for dust collection. I didn’t include the details of running a hose down the arm with zip ties because I was more concerned with the staying power of the mounting arm over time.

That is just your opinion. I am sure there is quite a few folks that can still poke their index fingers into the eyes of an unsuspecting passerby when drawing attention to the Statue of Liberty thanks to a bladeguard. If anything it saved the fence of my table saw from moving into the blade.

To get back on topic—You can make an articulated arm fairly easily.

Click for details

I have a neighbor with an arm similar to this one, that can swing out of the way, it’s fairly sturdy.

Redundant ain’t it? I read a post years ago that the best dust collector in your shop is the splitter/guard that came with the saw. Mine hangs on the wall like many others…I found that fighting the alignment problems made ripping operations more dangerous than going without it and I learned to respect push sticks and occasionally borrow from my jointer’s push pads.

I guess you do not use the riving knife either as essentially it stays in the same position as the splitter.

My saw is “pre” riving knife.

My overblade guard that Rick M posted above works very well for me and rides over my sled fence no problem. One knob holds it in place so it can be removed in about 5 seconds. I use the microjig splitter kit.
