dado for shelves

this is a jig to do dados on the RAS .
the object , is to make accurate and repeatable cuts for shelving and whatnot .
and not cut the saw table or the backstop .
as with all of my RAS jigs , they must do these things ,
and leave the table , backstop and arm at 90deg. ,
so it does not get out of alignment .
.
this first pic. shows the crosscut dado .

.
this pic. is the grove with shelf ( imagine ) the depth of cut is regulated by
raising or lowering the arm , and this jig has its own stop , that can be replaced
if it gets messed up .

.
this shot is the jig in it’s normal state , not to big and heavy,
it is high enough to clear the saw fence .
it is 11 1/4 ” wide , by 32” long .

.
this is the jig with the wings extended , for longer boards ,
over all , it is 80” in length , and can be simply moved in and out by hand .

.
this is the registry dowels , that fit in holes in the table .
the bottom edge is shy of the table fence for sawdust ,
and the wings also for this reason .
put the jig on table and slide to drop it in to it’s place .

.
these are the holes for various other jigs that drop into place also .
when all is said and done , the saw is ready to crosscut or rip ,
and there are no clunks missing in the table or fence,
and the arm has not moved from its square position .
.

.
the construction of the jig , 4 groves 3/8” deep x 3/4” wide
are dadoed into 2 pieces of pb ( or whatever ) and the boards
screwed together and the ends cut for the wing rests .
4 – 3/4’ dowels are in the square channels formed ,
( see ma , i can put a round peg in a square hole ) !
and 2 dowels are attached to one wing , and 2 to the other .
this whole thing is screwed together , no glue .
in case i need to repair or upgrade it later .
the stop is screwed to the back , and is replaceable .

.
now that we got this far , i’m starting to think of stops for repeat cuts .
why it’s a good idea to screw this together without glue !
.
as usual call jim , and he can answer all your questions . 8-)
( thanks jim . i got to go split firewood now )

David:

A great looking jig. Makes me wish I had a RAS again.

Wow this is quite a contraption.
Looks like I wouldn’t have enough room in my small shop for this, but wish I could have one.
David you are the master jigger. LOL

Karson, I have to agree with you. I said the same thing last night. Wish I had mine back too. David, you got some great ideas and they work fantastic.

Hey David,

Well though jig buddy. Nice too.

How do you register you dower from the jig to the table. Do you drill them through the jig and the table at once when the jig is in final position ready for production?

By the way, few weeks ago I relocated my RAS, alone. If you’re interested, check how I did it by myself

serge yes , after everything is done on the jigs ,
i clamp them to the table and drill down thru everything ,
them dowel the jig ,this keeps them centered where i want them .

nice move on your saw ,
you have to think like that when
you work alone .

Great blog David! Really well thought out jigs. I am trying to figure out how to apply some of your jig thinking to my shop.
