@JimsPicks To macduff it is a combination riving knife/splitter, primary a riving knife first as it follow the curvature of the blade, it is high and long, most riving knifes and splitters are never long enough for the safety at hand. This riving knife/splitter with a safety see through plexi cover allows the blade close contact with the fence, which many cannot because the guards fouls the fence hence the design. With the blade running high the sharp angle, the teeth force the material down.
continued, As the riving follows the curvature and the sharp angle of the teeth, no material can picked up and thrown forward because there is no space between the blade and the curvature of the riving knife, a shallow angle is contradictory to this. This is a design for the OJJ which has many options on safety. the operator of these safety devices macduff can still count to 10 on both hands after 60 years using woodworking machinery. slainte mhath macduff the albannach
@JimsPicks As stated it is a combination of both, specific to the OJJ which has many options for safety to prevent kick-back and binding. The OJJ is the Original Jimmy Jig may macduff suggest you search the name on Youtube and you will then understand macduff's direction on safety, Original being the first. the albannach justifies this reply
@seumas2 I watched the video on the original and a couple of others but I can't really tell how it works or what it does because it's all music and no one says anything and all those squares of picture flying in and out and no actual demonstrations of the jig in use.
@seumas2 But regardless of what you want to call it, it is still a splitter and not a riving knife. I am not criticizing his whatever it is in any way, I'm sure it works fine but there are millions of woodworkers including myself that have been doing it for decades without all of his contraptions and without an accident.
And what does " then understand macduff's direction on safety, Original being the first. the albannach justifies this reply" mean?
@JimsPicks Sir they are no contraptions they are safety devices and are preventive, hoping you are no the next one of 40,000 yearly table saw accidents in the US, the albannach
@seumas2 Maybe if the videos were decent I could see what it does but with those videos I still don't know what it does or how it works. Like I said, I am not criticizing it, I am just questioning its worth. I am all for safety but I can't tell how that makes anything safer.
I also can't tell what the point is. Is he just sharing what he made with us? Is he selling those things? Is he selling plans? Ditch the music and special effects and show someone using it with narration.
@JimsPicks macduff suggests you read my profile, there you will find the web page which should be your next obvious step, the plans are there for purchase, make the OJJ and or the alba table using a video presentation, narrate it with a North American accent, post for all to understand who have doubts on it's merit. If you would like to silence the music, there is a mute slider, purposely for the specifics to mute or to reduce the volume. Obviously not every one's taste, albannach
@JimsPicks continued, explanation, The OJJ is a sliding support platform 30ins wide by 60ins long, has a stationary or fixed fence on one end (right or left) it is attached to any table saw top, (bench top or others) has an aperture to allow the passage of the blade to and from the fence for a distance of 49 ins, allowing 4 by 8 sheet material to be cut 4ft on centre. In the aperture there are sliding inserts, one over the blade as a zero clearance, the other make the aperture.
@seumas2 I understand more about it from that paragraph then I did after watching several of those videos. And by the way I like that music. I just don't think belongs in those videos. There should be narration to help explain what you are seeing. I have a Scottish background so I think I would like to hear it narrated with a Scottish accent. What is your relationship to MacDuff and why is your user name seumas but you sign it albannach?
@JimsPicks Real name James Nairn McCombie/from Macthomaidh gaelic/English McComie/corruption to McCombie. McCombie's original breeders of the World famous Aberdeen Angus polled black angus in 1850's in Aberdeenshire Scotland. macduff my web name/ Seumas(Scottish spelling) is the gaelic for James/Albannach is gaelic for Scotsman
Try the video narration of the up front safety devices, on youtube, accent is from Aberdeenshire and the language is the Doric.
@seumas2 continued, Many Scots don't understand the language, although it is written but very broad. Not English and nither gaelic. Time served tradesman, carpenter, joiner, cabinetmaker, (with hand tools) served with the British Armed forces in the Middle East in 1956, lived outback in Australia now live in Canada. the albannach
@seumas2 Thanks for explaining. I thought seaumas2 and albannach were 2 different people. Also thanks for the interesting gaelic and Scottish tidbits. Wow you have had some amazing adventures. So how did you end up in woodworking instead of the family cattle business? I am a furniture and cabinet maker and I too do a lot of hand work with all antique tools. My power tools are also old. Most are industrial machines from the '40s by Oliver, Crescent and Yates American.
@JimsPicks continued, co-planer with the top. There is an outrigger with one line of friction along the top of the plastic pipe, which is portable on the out-feed and side support for the sheet material all for on site use or in the shop. The fence being fixed to the sliding table it will not deviate from parallel, yall or ride up. To this fence is attached all the up-front automatic overhead safety devices, not like conventional table saws that have them placed behind the blade.
@seumas2 continued, the OJJ is removable and hung on the wall, using the space for other woodworking operations, light weight at 25 lbs, clamps to the table saw, solid on over 3ft of edge pressure (T-bar) will take a sliding router in the aperture, no side support table required, all manner of other hand held power tools can be used in the aperture. (planer, jig saw, split router fence and a plunge spring loaded system on the stationary fence. next up the Alba table, the albannach
@seumas2 The Alba support table is 4 by 8 ft. knock-down fold-away woodworking support table set up on saw horses, portable light weigh one man operation. Will by-pas the requirement for a table saw uses only hand held power tools. These tools utilize an in-line rip, cross-cut circular saw, router (XYZ) drill press, jig saw and planer, mortice and tenon attachments. All positioned on any area of the of the 32 sq. ft frame.
@seumas2 continued, Think of a conventional drill press that has restrictions on the area that can be drilled, the drill press on the alba table will bore on the vertical (to 34ins) and at any angle. Left or right handed use of the circular saw and other hand held tools will take the scottish ripper and the rip snorter, either on the guide rail or free hand, the guide rail transverses one long side of the frame, adjustable hold-ins can be attached on any grids on frame. albannach
@seumas2 View the videos, self explanatory for those experienced in the use of stationary and hand held power tools and the dangers there of and can see the light. the albannach

That's not a riving knife. It's a splitter.

This has been flagged as spam show
@seumas2 Following the curvature of the knife does not make it a riving knife. It is still a splitter.
What is OJJ? The only reference to OJJ I could find was Office of Juvenile Justice.
