Question for the Jig freaks...

[RodKirby]

Someone posted a link to this guys illustrations - no text just pics - great stuff!

I have spent a lot of time trying to work out how this works.

I presume it's a Table saw jig for cutting miters (?). What I cannot work out is how the (support?), block on the moving top doesn't get in the way - all the time. Unless it's maybe a sinlge-use jig.

Thoughts anyone...

Well if it's for cuting miters I can't see how it could work either. Maybe it's used for something other than miters, like cutting thin strips (set it just outside the blade and move the fence over for each cut) or mabe checking that the blade or fence is square to the miter slot. Hope we find the answer, you've got me wondering too

The piece on the nose is the stop block -- the actual cut is on the straight side near the catcher's side of "home plate".


For it to work well the pointy end would have to be away from the blade so the stock is pushed towards the stop block..... But it seems like the table saw table would need to be pretty large to get the fixture and the stock that far in front of the blade.

Don is exactly right. I've seen this in a magazine somewhere before. I am 99% sure thats what it is.

Baseball analogies don't mean squat to Rod - He's in Australia where they play cricket, not baseball, and on top of that he's told me he cares not a nit for sports, anyway.

Draw it with wickets. I've got to believe Rod has at least seen a cricket match even if he could care less.

question?

If I'm not mistaken that may be a thin strip ripping jig. It is adjustable for different thicknesses and rides in the miter guage slot. eezlock

That is what I thought it was when I saw it. The board underneath would slide in the miter slot.

Might also be something for a router table. Acts a little like a fence but I would think the square end piece should be larger for that.

It could be a adjustable fence for use on a band saw, or a router table. The little block looks like it is the stop for the "most" forward movement.

Yep, so it is. I have a mag around here somewhere with that jig in it.

Seems like a convoluted way to set up an auxillary fence for ripping thin strips.

Would you really want to use a jig that rides in a single miter slot for that? Seems like it would be unstable.

And why is the adjustable fence on there any better then the regular fence?

I dunno, I think Niki's way of doing skinny strips beats this one out pretty good.

[DonHo]

"And why is the adjustable fence on there any better then the regular fence?"

I don't think it's used as a fence. I think you would place it on the left side (or the opposite side of the blade from the fence), the adjust it to the thickness of the strip you want then place your board against the fence and slide it over until it contacts the jig, then make the cut. Slide the fence over until the board is against the jig once more and cut the next strip, etc. It's more like an adjustable stop block.

[radhak]

That is the jig from American Woodworker, Jan 2007. It's for ripping multiple thin strips of exactly same width from a wider piece of wood : you fix it on the miter slot on the 'other' side of the blade, and after each cut move the TS fence closer (you don't move this jig at all).

The distance of the 'support block' from the cut-line determines how thin your final strips are.

[LarryG]

Although I've not seen this particular jig before, I've seen others that function the same way, exactly as DonHo and radhak describe. The little block that Rod asked about in his OP acts like a featherboard, in addition to being the gauge block.

EDIT: I should say that the block can act like a featherboard if the jig is rigged so it won't slide in the miter slot -- which, upon further review, I see that this jig is not. Easy enough to fix; but if that's not done, the jig should be set aside before making the cut.

[Garasaki]

Ahhhh I gotcha now.

I personally don't like having to move the (saw) fence for this sort of operation.

This could probably also be useful for a router table though.
