I started on a new sight today and was making a few rips. They had a R4512 on the third floor. My initial thoughts were wow how quiet. Being on the jobsite they have the riving knife, blade guard, and kick back foot installed. I did the right thing and tried to work with it. This was my first time using TS with all that stuff in 10 years. I have 3 TS’s ranging from a benchtop to a 3hp PM66, none of them have any guards at all. Yes I still have all 10. my first concern was that the riving knife moved back and forth, not enough to contact the blade but I wondered if this was ok. I am very anti gaurd I feel they serve as more of an obstruction and hazard than a safety device. The very first thing it did was bind up the board on the kick back foot causing me to force it loose since I was ripping a 12’ board. The next rip was 3/4” and it all had to come off in order to get the fence closer than 1”. all in all I think it is a nice saw. I just wonder how many of us still have all the “safety” stuff on their saw, and any advice for how to get along with it. I know the safety guy would probably get my money if he walked by and viewed a TS with the guards lying under it, but how do you cut less than 1” with it in place.

Thanks sorry to rant I just can’t seem to get along with it, but I am trying.

I use just the riving knife on my sawstop and it hasn’t gotten in the way once. It works on non through cuts and angled cuts. I cant stand the guard that it came with but the riving knife is great!

The riving knife doesn’t get in the way. in fact I think it is a good idea, but the rest of the crap just drives me batty

I have never installed my guard/anti-kickback pawls for the reasons you cited. I did try the riving knife briefly but had problems with several boards pinching and binding on the riving knife so took it off 3-4 years ago. I do drive a wedge in the kerf on those tension boards that want to pinch/bind.

gfadvm totally agree, but this on a union job. they don’t care if policy said stand on your head and drive nails with a rubber mallet then thats what they want. some safety is really blind.

see pages 34 and 35 for a rudimentary stand off fence for sheet goods. when dealing with thicker stock, fabricate a slightly modified fence to accommodate the work piece:

i made one of those stand off fences and it’s kept me safe on several occasions. of course, a thin piece could also be ripped on the offcut side of the blade, perhaps using a jig like this:

was bind up the board on the kick back foot

BTW, what’s a “kick back foot”?

I’ve never had anything “bind up” on the riving knife unless I put in a thin kerf blade. I really like the riving knife.

I generally like the safety guard when it can be used; which is about half the time.

As for those anti kick-back pawls; might have been a good idea in concept, but the Craftsman 21833/Ridgid R4512 execution is a piece of crap. Fortunately they are not too hard to take off.

Have your say...
