can you identify this attachment/jig?

[luvit]

hi.
my grandfather died in june. he had large number of typical old woodshop tools.
i received about 1/3 of them.
there were a number of attachements and jigs which i did not take, but one was just delivered to me.

• can you identify it?

Wouldn't bet the bank on it, but it looks similiar to several planer knife setting jigs I have seen.

mm k. it could be, but i think it's one of 3 items.

• he had an old 8" table saw
  old jointer
  but i cannot remember the 3rd item this may fit, yet.

but this accessory may have been part of another tool which was gone before my time.

Could it possible be a jig to map out door hinges , to be mortised out , just a wild thought, Frank

I think it’s “Trammel Point” with the points missing. It is used to layout circles and/or arch’s.
Typically in woodworking or sheet metal fabrication.

see examples...

i got his trammel points, but this is not one of those.
here are more pictures, i should have shown this earlier.

both ends extend, there are numbers, when the numbers run-out, there are notches.
hope this helps. lol.

What's the spacing between the notches? It looks like the pivoting lever might drop into the notch for some type of adjustable, fixed increment stop.

alright, harvey. you got me in the right direction.
you see in the pic, below, there is a small horizontal rusty clip?
that drops into the notch, as you change the notch, a different number is exposed on the end of the rod.
raising the lever appears to not be part of that clip.. you need an allen wrench to adjust that clip.

from the previous pics, i just don't know what tool for which this is an accessory.

luvit,
i know i should switch this to your post, but i noticed one of the aluminum clamp parts has "ght" and maybe "52" on it... are there any other markings? i think i understand how it works, with the cam lobes (similar to motorcycle chain tensioners) and rusty pin that must poke through the bottom when the lever is pulled up (alignment, and light securing). ght brings up universal pillar tools, but your item doesn't quite seem to fit that... good thing i don't sleep much more than 3-5 hours a night, this has kept me up for a while!

hey steve, i'll look over this thing with your thoughts and post some new pics.
thanks for the interest!

The 8" table saw, who manufactured it?

 

[luvit]

I thought it was an old craftsman model 8" table saw, but I can double check.

Sorry, Another question, were any of the tools your grandfather had painted metalic green and branded INCA. The mixture of what appears to be die cast aluminum and black finished steel was typical of INCA's accessories. They also made a large number of specialty accessories.

Could it possibly be one side of a routing machine that the router ran down the two guides? They used to sell them that had a universal mount and the router ran down two guides. They were used to make fancy spindles or post by using the router to cut the design into the wood. Not sure what the technical term for the machine was.

Definately for layout/marking something?

When you flip the levers do little pins poke out the bottom?

The cams are for setting the distance to the pins vertically,the notches set the distance horizontally.

What its setting it for...no idea!

Also....I just read,salt and vinegar will remove all that rust.

 

[bullnerd]

Any luck?

 

[bullnerd]

I'm not giving up!

Alright, no word on the table saw make/model or the jointer table. Both are at my dad's and he keeps forgetting to look at them.
No Inca equipment.
There is an old Walker-Turner Company Inc Bandsaw which meets the era.

Kev, I thought like you did, but the bar does not allow seemless guiding.. that is, it's not a true or flat guide so you're cutting would look poor.

BUT.. you and bullnerd may be onto something..
There were some pins frozen where you hammer them into wood and then the lever is used to pull-up the pin.

The next pic has a half-moon disc to place against an edge. You can position this tightly with a wingnut after you hug the edge.. notice the pin bullnerd pointed-out in this one hole.

The allen wrench is just to replace a metal pin for those slots on the shiny metal, but notice the j-hook on the far right.
This allows a small plate on the end to slide up and down to hug another edge of a board...

finally, there are 3 pins... one on each end and one in the center.
also, see how the bar bows in center? i think it's made like that.. could it be for tension?

There are some mechanics to the device which I may not be able to describe, so I'll attempt to get a video of this in-action.

[luvit]

and thanks for your enthusiasm of helping to figure this out!

 

[bullnerd]

Damn! Thats a good one!

Thanks for the update.

 

[Kevin54]

Luvit.....where the numbers are on the rod, are they 1" apart and are the notches the same distance apart?

Does the rod that slides out, is there one on the other end also with the same numbers?

How long is this part overall?

 

[bullnerd]

Yeah hard to tell,they look like CM ?
