I would like to take my ss in the lathe position and make it into a sanding type jigsaw.

here are my thoughts.

put drill chuck on, add a shaft that is attached to a cam.
when the chuck goes round, a follower (another shaft) that is positioned on top of the cam will then go up and down.

on top of the shaft that goes up and down I would have an attachment that will hold a emery board.

this "thing" would be used to sand the inside straight edges of of scroll saw work.

to get a picture of the "thing" picture a hand held jig saw upside down in a vice. Instead of a blade you have an emery board in it's place.

problem with this is: hand held jig saws are noisy, and a tiny table.

I have been having trouble finding the parts to make this thing

TIA

Can post a sketch of this concept?

the left to right shaft would go to the chuck, the yellow vertical thing would then go up and down because of the cam (pear shape).

I would come up with some type of device to hold the emery board in place

Farley,
It sounds like you are trying to reinvent the die filer. Since they do make sanding strips that mount in scroll saws I am assuming you want something that need not be attached at the top. I would recommend picking up an old Shopsmith jig saw. Shopsmith also made files that could be used in the saw. Instead of files you could attach sandpaper to metal or even wood blanks shaped like the files.

The saws appear regularly on ebay and you might also check to see if Bill Mayo might have one to spare.

I just finished posting a method of doing what you describe using the old jig saw. I've been doing this sort of thing for a long while, just one of the advantages of the older jig saw.

See:

If you go to the seventh post you will see the Popsicle stick version.

yea that's what I am talking about.

I use to own a ss jig saw, but now I own a scroll saw by Dewalt. The scroll saws use both upper an lower holder, I forgot how the SS jig saw worked.

Your idea reminds me of a sabre saw attachment that came with my old Dewalt MBF radial arm saw. You can remove the saw blade and guard and mount this contraption which converts the rotary motion of the saw arbor to an oscillating motion to drive the sabre blade. Can't say I've ever used it for any projects, but I did clean it up, mount it, and give it a go try I brought the saw home. Works OK. I thought it could be handy for cutting circles as you could lock the saw carriage in place along the arm, turn the head 90 degrees and just swing the arm around the column.

I suppose you could mount an emory board type attachment in it and use it for sanding too - I never really considered that.
