What are these Homeade Jigs for?

[chris hood]

I acquired different jig with the Grizzly Table Saw I purchased from an individual locally and have no clue what most of his home made jigs are for. Maybe some of you can help identify them.

First pics: Left Side = Router Jig for Dados. Pretty torn up. Right Side = Taper jig for table saw. It rides against the fence.
Second pics: No clue
Third pics: Left Side = Circle jig for router. Right Side = Some sort of special purpose sled?

Agree with Rob on these. The last pic is a miter sled. It sits in the miter slot and can be adjusted to whatever angle.

You could always ask the guy you bought it from what he used the different jigs for.

I think the second set is a type of tenoning jig for a router.
It's just all closed up in the photo.

I made one very similar to the first post left. Yes I use it to cut dados with a top bearing flush trim bit. The useful part is that I use a scrap of the material that will go in the dado to set the width. That way if I have material of an odd thickness the dado is always the correct width. The down side is that I can't use that jig to make dados less than 1/2" wide plus a whisker. The smallest top bearing flush trim router bit I have is 1/2".

The left hand one in post #3 appears to be a circle cutting jig for cutting large circles using a router.

The right hand item is a home made Dubby Crosscut sled. They were also used to cut angles, using the calibrated scale on the left hand side, for multi-sided frames like squares, pentagons, hexagons, octagons, etc. Here is what the original Dubby Sled looked like.

One thing I have learned the hard way is to label jigs I make so that years down the road, or in cases such as yours, that they can be identified for what they do.
