Topic tags/keywords: riving knife table saw question

Does anyone know a way to upgrade the DeWalt DW746 10” Table Saw with a riving knife? I use a splitter behind the blade, but a dedicated riving knife would make for quicker change overs.

Thanks!

I highly doubt it. I think to have a riving knife, you have to buy a saw that comes with one.

I think Gary Katz showed on his site how to McGyver a
bosch saw to take a self-made riving knife. You might
look into that. That was for a portable saw.

For your saw it would probably be a matter of taking the
saw down to blade shroud and welding or bolting a
spacer to the shroud behind the blade. Then you
attach your riving knife to the spacer.

It’s not a riving knife, but a splitter set. You may wish to check out http://www.leestyron.com/sharkdw746.php

I think splitters are the most avialable.

I know this is an old old thread, but thought I would share a little about the Dewalt 746.
These are splitter equipped saws in the US, however they have riving knives in Europe.
There is a bracket that attaches to the arbor and that is what holds the RK.
I have seen a picture of one, but cannot lay my hands on one to replicate.
They simply will not sell that bracket over here.
If any European Members have one of these, I’d be interested in some drawing and dimension’s of it.
Thanks, Guys.

The BORK is the only aftermarket riving knife I know of, but I don’t think he has one that fits the DW746.

Bob and I discussed his Bork before it came out when he was designing it. It’s a nice option for some saws.

I do make splitters for the DW746, but not riving knives. I make riving knives for the DW 744 and 745 though.
Love to be able to put them on a 746 as well.

I did find the image of that bracket that I mentioned.

I also have a link to that manual.
http://service.dewalt.co.uk/PDMSDocuments/EU/Docs//docpdf/dw746_eur.pdf

The part looks easy enough for me to duplicate I think.
Just need one of them or at least the details.
The part number is 140 in the manual and it says that it is discontinued now.
Still a lot of 746’s out there looking for a riving knife fix. :)
Thanks.

Leeway – did you ever get any details on the riving knife for the Dewalt 746 from anybody in Europe? I have a small fixed unit that I’ve made (after getting hurt by the flying board), it seems to work but a unit that goes up and down with the blade would be much better.

It looks like the articulating arm for the riving knife pivots on the arbor shaft, which means it must have a high quality/high speed ball bearing in there. Just visible below and to the left of the arbor flange looks like the actuating arm that makes the riving knife stay level with the blade at all times. It can be done (I did it for my Unisaw), but you have to make it up as you go. The trick is to pivot the articulating arm concentric with the shaft. Good luck with your search.

I haven’t found anything else out about it. I know Dewalt makes at least two other models that do have riving knives. This was before the mandate kicked in.
Sadly though, they are different than the 746.

Lee – thanks for the feedback
Looking closely at my 746 I might be able to make a ring that fits around the assembly that house the axle of the blade. The ring would have to have some set screws to lock it on. Then I’d have to weld an arm to the ring that would support the riving knife thus as the blade and assembly moved up and down so wood the riving knife. The final part would look something like the image you posted. However I’d much prefer to find one already made!

I can also visualize what runwithsissors is suggesting either way it will be a lot of trial and error.

I have a crude stationary rectangular spliter that I made from a handsaw blade but I think for now I’ll make another stationary one that follow the arc of the blade.

You can google the blog I did on my Unisaw riving knife. That was several weeks ago. Yes, trial and error is the only approach that I know of. For mine, I made a base upon which the articulating arm can rotate. The base itself is not an important part of the set up, it’s just something to attach the riving knife arm to, and for it to rotate on. It took more time than the riving knife itself. But I am pondering a simpler, better way to do that. Have several ideas in mind, but have to try them out.

Can you please give me the direct link. I ran a Google search and it produced numerous interesting hits but I don’t think I found yours.

I think I have seen it before and may have saved the photo’s just because I thought it was cool. I didn’t save the link though.

Bob Ross from Walnut Acres and I brainstormed initially when he was starting out. We couldn’t come up with much the direction we were headed in, but he came up with what he now makes.
His only fits a few saws so far.
