A riving knife I made out of an old saw blade for a Ridgid R4511 Granite top table saw. The idea was not mine – I read about it elsewhere and a template was provided in that post, if you google it I am sure you can find it.

The one I made is the Red one, the Silver one is a Shark Riving knife.

Just thought I would share for any 4511 owners out there – these are easy to make with a cheap cut off tool and a grinder.

Nice. Eliminates the problem of matching blade and knife thicknesses, assuming they are the same model blade.

I too have made a couple, as my saw takes anything from ten inch to sixteen inch blades .Therefore a need to change the riving knives which I would not work without(my strong feelings on the subject) so I made at least two of them I simply used an agle grinder with a metal cutting blade then finished on the tweve inch disc sander.

Thanks for the inspiration. Took me about an hour to get it this far. I still have to finish cleaning it up on the belt sander and put a coat of paint on it. I feel safer now being able to have the knife in all the time.

Yes it is a Wadkin sliding table modern dimension saw.The blade as said goes up to sixteen inches and has two motors one main motor is seven and a half hp, and the scoring blade motor is around two horse power.It is my pride and joy of my woodshop.I love all wadkin tools as they are truly industrial quality but not old dinosaurs. I also have there radial arm saw and this is also beautifully made too. The main saw sliding table is made as said by the wadkin company they have a branch in England in a place called Bursgreen and some models are therefore called wadkin bursgreen, but mine was made in their main factory in England. Itweighs in at 700 kilos wadkin is the sister company of the famous German machinery firm called Altendorf.they are top quality machines My saw had to be totally dismantled every nut and bolt down to the bare shell for the delivery men to get it through my door first my house is on a hill so it had to be brought up the hill and then manouvered around to the back of my house and taken up a set of concrete steps then up a grassy sloped hill up to the front door of my wood shop.Then carefully with about a half an inch to spare with the main sheel it was eventually brought into the main workshop and positioned then a day was spent setting it all up and aligning it everything was difficult even the large cast iron top weighed so much it took four men to lift it.LOL here is the machine and an idea of some other machinery they manufacture I hope you like it.
