Topic tags/keywords: unisaw riving knife

Finally got my Unisaw. $500, 3 hours of driving, Delta right tilt 36-815 from 1997, came with a Delta T3 fence, HTC mobile base, a few cheap blades, and just the left cast iron wing. No splitter or guard. Would have preferred a left tilt but never saw one for less than $1000 used, so I jumped on this one and perhaps will buy a left if I feel like I need to.

Aside from now having to actually add 220V to the garage, safety is first in my mind. To that end I’m considering the Bolt On Riving Knife (BORK) or the MicroJig MJ Splitter. I recently discovered the new as of last year Shark Guard Adjustable Riving Knife (ARK), however I can’t really find any reviews or even a mention of anyone using the SG ARK. Has anyone here used one?

I have developed a true riving knife for right tilt Unisaws. Google (on this site) “Retrofit riving knife for Unisaws.” Don’t pay much attention to the photos, as they were taken during early stages of development.

I have seen Lee Styron’s ARK knife (not in the flesh, but in the Shark Guard videos), and it looks quite good. It hugs the blade quite closely, but does require manual adjustment when you change blade height. It tilts with the blade like a true riving knife. If I didn’t already have mine, I would buy one of Lee’s. I like it better than the BORK, as it looks more robust.

I am ready to start sending out my riving knives whenever I start getting orders. Initially, I will charge $150 for the whole thing, with one knife (thin kerf or full kerf). $15 extra if you want both knives. If you only want to get one, I’d go with the thin kerf, as it works just fine with full kerf blades.

I only made a small run of these—15. When they are gone, I doubt if I’ll make any more, as they are very labor intensive. Lots of little parts.

I’d be interested in ordering one. Can you post or message me current photos, and installation instructions or video? Thanks.

Just an FYI… but have you seen the riving knife that Clint made for the Uni over at the OWWM site? He is in South Africa and making parts is about his only option apparently :)


Here is a video of it in operation.

Probably a bit much for the average user though…
Another consideration would be the Delta disappearing splitter, which just bolts on without any modifications needed to the machine.

Cheers,
Brad

Hello, same question here. I have a 1997 Unisaw (Right tilt) and was going ton buy SharkGuard. Not sure about “manual” riving knife ajustements… and pricey…

BORK looks good too.

Tombed, I know the SG ARK has only been out since last year, but I haven’t found any forum or blog where someone has actually used one. The OWWM user from South Africa made a beautiful design, but I think he actually had to mill parts of his Unisaw to make it work. I’d still like to see runswithscissors current design.

Finally ordered one. I’ll see the results in 5-6 weeks…

Have your say...
