I am not a woodworker. I work for a contracting company and we are on a government installation and use vintage government tools. I am looking for a table saw guard for a Rockwell Mdl 34-461 unisaw. In searching I came upon this site and hope that someone can help me find either the plexiglass guard or a parts manual so I can search for the part number. Thanks in advance.
My Rockwell Shop Saw is the same vintage... and I have the guard itself (without mounting hardware), that I picked up at a Habitat For Humanity.
That saw was considered to be a series designator of CS-4K... so the guard, at the time it was built and sold, did not come with the guard as standard equipment. As such, the parts schematic for the saw does not show any guard for it. Being the guard was sold (extra) as an accessory (34-639 Blade Guard For 10” Unisaws CS-4K-1), it has it's own
part's diagram: http://vintagemachinery.org/pubs/1141/3703.pdf
If they ever bought one and had it mounted to that saw, then the front of the splitter slides into a slot in the back of the blade insert plate, down into the mount, which bolts to the rear trunion, above the yoke, behind the blade. The back mount attaches to a shaft that screws into the back of the trunion. If those are already there-- then you have more options open to you than the original.
But, a new blade guard of the same design doesn't hold to current government safety spec's unless you said it was original replacement, right? Your loophole around that and your canned answer to any safety inspector, is that the original saw did not come standard with that guard. So any guard would be safer than none. (Let common sense prevail.)
I have an orange one that I took apart because it had a broken spring. Instead of fixing it or adapting it, I made another of a different design. I think I still have it somewhere here, but it is in parts and (noted again) I do not have the other mounting hardware.
Otherwise, Having done this again recently for my new panel saw, I have some alternative recommendations that meets OSHA reg's, is more usable than the original, and that doesn't break a budget. If you want those leads, just ask and I'll PM them to you.
