Katie Jig

Not sure if this is the right sub forum for this but...
I just got a Sommerfeld Katie Jig, they had them 25% off at Christmas time.
Following Marcs video, my first try went very quick and easy. Near perfect results.
My question is- in the video, Marc shows how to loosen the fit. My problem is, it’s already too loose. Anybody here know how to tighten the fit?
Thanks

I am not familar with that jig. My go to is the Gifkins jig....
Can you adjust in the opposite direction than shown to loosen the fit?
No the backer boards a mounted to an aluminum extrusion.
PS this is the instruction for the Gifkins, see if that helps...

Did you get the instruction book with it? Check that. You also need to use an engineer's square to make certain the fingers are perpendicular to the frame. The backer board are sacrificial and can be replaced frequently.
Also, not being funny, but do you have the correct size cutters?

Th Gifkins Jig has very specic size cutters. The Katie jig may be the same.
Tom- yes, but it doesn’t say anything about it.
James- yes, the cutters come with it.

Are you using the individual fingers, or one of the standard ones?
The one Marc shows in the video- its one piece.

Tom- I guess I should say, he shows it at the very beginning, where he says that how they come now.

Got a reply from Jay at Sommerfeld yesterday.
He said what I need to do is make a new backer out of hdf (5/8), then shave a VERY small amount off the thickness. Try it, if needed, take a hair more.
I’m thinking of starting with removing around.008 for starters.
Now if I can find hdf anywhere. No one around here sells it, except to order a full sheet.

Looks like the jig can only be adjusted to make it looser, not tighter.
The Gifkins jig come with 5 shims installed (and spares) and they can be removed or more added to adjust either way,,,

I would say that what has to be shavedoff only needs to be the thickness of 2 sheets of paper?
Kinda what I was thinking James. Around .006. Might go .008. If too much can shim it.

You might try to find a nearby woodworking supply store (Rockler, Woodcraft, etc.) to see if they have some smaller pieces on hand that are the right thickness.
