Topic tags/keywords: dust collection unisaw shark guard riving knife question

Good morning! I’m new to LJ and have enjoyed reading the forums. Time for that first post.

I recently built a kitchen island and recognized the need for some upgrades to my old Rockwell Unisaw. It’s model number 34-771, serial LJ7014. Probably a late 70’s model.

Safety first – Understanding these were not made for a riving knife, I need a splitter of some sort. Blade guard makes sense too.

Next is dust collection. I’ve made a sloped floor and sealed the motor opening using a plastic tote from Lowes. I need to cut a port in the back and do something for dust off the blade. I think a blade guard makes sense here as well.

I’d appreciate your suggestions. I’ve considered the Delta disappearing splitter, but that does nothing for dust. I wonder if the Shark Adjustable Riving Knife would handle everything above the table and 4” port cut low into the cabinet would handle below.

I’ve attached some pics so you can see what I’m working with.

I’m not familiar with the Shark riving knife, but I did use their overblade guard and splitter for some time on my Unisaw. I really liked it. I subsequently came into a used Excaibur and replaced the Shark, but I liked the Shark better. I did eventually sell that Uni and the Shark went with it. But I think if you hope to catch dust with that shop vac using both a cabinet port as well as an overblade pick up you’ll probably be disappointed with the performance. It should do well on just the over blade, but suffer on pulling enough air through the cabinet.

Thanks, Fred. The cabinet port is more future-proofing than anything else. My thought was to hook the vac to the guard when sawing then vacuum out the dust in the cabinet afterwards though the port. When I get a proper DC, I’ll hook it to the cabinet then branch off to the guard.

See any issues with that?

I just shop-vac out the cabinet every now and then, so can’t really help with your DC… and feel that the blade guards are more of a distraction than a safety device (only provided as a CYA against the regulations). But as far as the slitter goes, I have and recommend the Delta disappearing splitter. Works great and super easy to push down when doing non-through cuts – operates with a single finger and no tools involved. They originally came with the Uniguard over-arm guards. About $75 on Amazon, or you can usually find them a bit cheaper on the bay.

Thanks, Brad. I hear you on the guard. Do you get face full of sawdust when ripping? I was hoping the guard would help with that.

Have your say...
