After finally starting to feel like my tiny one car garage is a shop I’ve started working on improving the shop. The used Ridgid 4510 table saw I have didn’t come with the riving knife, apparently the previous owner tossed it with the blade guard, and I thought it would be a good idea to have one. It was difficult to find a replacement to purchase online, so I decided that I would try to make one.

I ordered a 12”x12” 1/8” sheet of aluminum and made a couple of “first drafts” out of some plywood to try and develop a template. I only had Sunday to work on anything this weekend, so I was pretty sure I would be able to punch it out. Once I got the fit right and a shape I liked I traced the template onto the sheet of aluminum and cut it out with a jigsaw. After a whole lot of fine tuning and shaping its in the saw, aligned, and works beautifully.

With the riving knife done I started cutting some pieces of hard maple and peruvian walnut to make a couple of mallets. The previous weekend I made a few zero clearance inserts for my table saw as well as a crosscut sled. Things are progressing slowly, but well I think. I’ve been overwhelmed with all of the projects I want to get done lately so I had to make a to-do list, and it has helped reduce my confusion and anxiety.

Ok, I think that’s it for my first blog entry.

Congrats on the new, to you saw, and the accessories that you are making for the new toy.
Hmmm, there might be a market for your new and improved riving knife … ??

Congrats on the saw, funny what people discard and great idea to make a replacement riving knife

After assembly of my new Grizz, I started using a riving knife for the first time … Gotta say, I like it.
on your design, which I think is really cool, you might consider rounding the point at the lead end and the trailing end to avoid spearing the wood and your fingers while doing setups.
Yesterday I cut some pine that had a lot of tension, and it caught up on the riving knife … mine has a rounded lead end and with a bit more feed pressure the wood slipped past. (Thanks for the beveled edges).
Just a thought.

Thanks! I’ve been thinking about doing that actually since I’ve noticed that seems to be the shape of riving knives on nicer saws. I’ll be sure to post a new picture after the modification.

Have your say...
