Ridgid TS 3650 -using the blade guard for dust collecting with an over arm is a bad idea.

I wanted to do something like this

but using an articulated overarm that I just bought
The down pressure that the articulated arm applies on the hose in order to keep it in position will keep the blade guard pressured to the top table making it difficult to push the wood into the blade

Besides that if you cut narrow strips it is difficult to push with a push stick if the narrow strip is to the right of the blade. Also the visibility seems to be poor, you need the hose and the attachement (the black piece in the picture) to be …transparent.

Looking for a side toward the whole thing, as in the picture, all looks fine but when you sit behind the push stick—it is not that easy to see through or around the whole thing to get a sense of how your wood and blade are moving

Any comments ?

Built an overhead guard with vac and light. Never worked well. Besides your saw shouldn’t be throwing a lot of dust topside except on shaving (no cutoff) cuts.

All over arm blade guard/dust collection hoods are a PITA. That’s the price of keeping your fingers safe. I have an Excalibur over-arm that I use all the time. It’s supposed to be one of the better ones on the market. It has the exact same problem with ripping narrow pieces that you describe with yours. I have to raise it out of the way in order to get a push shoe/stick close to the fence. It interferes with some other operations too, but the narrow ripping is the most common one. The plus side is that it catches most of the fine dust off the saw blade. I continue to use it for that reason. My lungs and sinuses are grateful.

So what I am seeing/experiencing is normal? I expected no dust on top as I see in many educational videos

The diameter of the 2½” vacuum hose used for the blade guard extraction is too large, inhibiting the proper motion of the guard.

Try using a 27mm hose or a 1¼” hose, with that hose suspended from above.

Try sucking from the rear instead of from the top to not inhibit guard movement.

I agree with wingless. The dust port + hose at the front of the guard is inhibiting its pivot action. The guard should be laying flat against the saw and gradually raise as the stock slides under it. You’re creating a pinch point on the pivot action of the guard. I would try moving it to the rear and use a more flexible 1-1/4 hose that hopefully weighs less and move the reducer farther downline…maybe level with the table where your squeeze clamp is.

I might take it one step further and get a 2-1/2 blast gate and attach that with a reduce to the saw body right around where the squeeze clamp is. Then i just have to plop in the 1-1/4” flex hose and guard. Make it a quick change operation for the times you need a miter gauge or cross cut sled. Just my thoughts…hope it helps give you some ideas

I could see a long time ago that a blade guard w/ a hose attached to it w/ a hole drilled through the top of the guard would be a pain in the a$$. I’ve never used a blade guard at all on my saws, and yes, it does throw some fine dust on the top of the saw, but I can put up with that in order to be able to see what I’m doing when working the wood…...But that’s just me….!!

that is the hose size I am using
There is no port at the back of the blade guard
It seems that I might need to fabricate my own guard with a collector port using some plexiglass

It looks to me like you drilled the hole for the hose to fit in, you drilled it too close to the end of the guard. You should of drilled the hole right above the blade….If you look at the picture again, you’ll see that the guard is lifted up just a little ( looks like it to me, but I may be wrong). Years ago I did the same thing with my old Craftsman saw (drill it in the center above the blade), and it worked good. It just impeded my vision too bad….I did away with it.
I still have the old Craftsman and the blade guard…..I use the Craftsman, and no guard, for dados and rabbits. I have a 5 h.p. Delta X5 for all other cust and operations….This thing is a beast….!! Check out my woodshop pictures..

That looks like this blade guard.

If so, then to effect a rear suction, a port is required to pull from both sides of the riving knife.

Don’t blame me for that :-) I am a newbie but I am not dumb. What is in the picture is not my saw but it is the same as what I tried to do last night. That is the original blade guard that came with the saw

Here is one that was made buy someone (found on youtube https://www.youtube.com/watch?v=XFyGhu43tUU)
I still don’t udnerstand, since he build it why did he now put it at the back side ?

Another guy molded a pice of PVC; he is collecting at the back side of the blade…which is better rear front or top?

He is using a shopvac for the entire system (lots of tools)

Interesting, I guess when you look at the cutting teeth cutting on the down rotation maybe the dust is carried back to the top where the teeth come up on the back. If that is correct then this also solves the blocked vision issue. I guess its time for a slow motion video to show where the dust is traveling from & to.

I didn’t say you were dumb…I guess I looked at the picture thinking it was your saw….My mistake. And don’t take offense….We’re here to help if we can….!!
