this is a jig i made years ago, it devides any angle for miters .
the circles have mesh teeth that rotate both sides together .
i originaly used sand paper , but it wore out quick , and the
circles slide singularly .
i found some rubber “v” grooved mat , and glued it to the sides
of the circles so they mesh , ( it’s not the best , but it works for now )i had to re-cut parts for this new improvement ,
as there wasn’t room for the mat .
it is registered to the table with dowels , that fall in holes for them ,
and is centered in the cut line .
with a board parallel to the RAS fence , i placed the stops on the circles,
so they are straight across and paralell to the fence.
( i will probably make them with smaller dowels also soon ,
and make various mounting positions for them on the wheels .
you turn the wheel , it turns the other one in reverse ,
put your adjustable angle against the stops , and turn the wheels until it
matches . in the front right of the jig , is a thumb screw that holds the wheel from turning .
DON”T FORGET TO RAISE THE SAW , or you will cut the jig !
this is just a model , maybe charles maxwell will teach us how to make gears sometime ?
the idea is that it could have positive stops at major angles , just like the chopsaws.
arms can be extended with stops for frames or multiple pieces .
this first pic. is just truing the wheels around its dowel

in picture below
when set .


notice thumb screw in pic. below

OH Wow! Brilliant. Your ingenuity is unsurpassed David. I suppose someone could incorporate this idea onto a crosscut sled for a table saw?

Your like this old country singer I know, I’ve been playing music with this guy for over ten years, I mean hundreds of songs, and he’ll say to me “here’s one I haven’t played in a while” and it will be a song I have never heard before, and it will be awesome. I’ll say “In all the years we’ve been playin music you never once played that song.” He’ll say “I forgot I knew it.”

scott ,
i have designed one for the tablesaw ,
but it requires linkage or cables to go over the saw blade ,
as the wheels must work opposite of each other .

mucho complicado !

larry you could use one on the beastie ?

That is just too ingenious. How do you keep the wheels from moving from one cut to the next? Maybe they are tight enough against each other and it’s not a problem?

Very Cool idea! Could have lots of fun with this on a RAS.

Thanks for the demo.

Brilliant jig David. It always amazes me to see how many ways tools can be made to perform different tasks.
Just the same I’m glad I have a sliding miter saw, because I have just about run out of wall space to hang more jigs.
Enjoyed your blog.

good stuff! I guess it would also work with sliding compound (I have neither :-)

David: A great performing jig. That looks like it should be made with a track and a crank handle to move the two discs in sync.

You should be able to do the same for a table saw if the disc’s were bigger and the blade was further out to the front. Maybe a big gear to the operator side driving a smaller gear underneath the disk that holds the wood. That would allow the blade to get into the area where your disks are touching on this version.
