Hi Bill

The knife is secured by a screw from the front end of the arm. Further, the knife is also held within a mortice so that there can be no sideways movement.

I shaped the brass end, cut and fitted it to the arm flush to the end of the mortice, then removed this to cut the mortice for the knife. After a dry fit I epoxied the brass end, pinned it with brass rod (1/3 of the way in from each side - not all the way through), and drilled and tapped the thread for the knife-holding screw.

The other feature is the tenon that keeps the fence square to the sliding arm. This can just be seen at the rear of the knob.

The slot was made with a 'tailed router (sometimes it is the easiest and best tool)!

My apologies if the pics are not as clear as possible - having a little difficulty tonight.

thanks, that was clear

>Very Nice! I have been contemplating making one myself, although more in the 'panel guage' I think it likes to be called (large fence, long arm). I wasn't thinking so nice as yours, it is inspirational.

So, how is the performance? I would be betting very good.

Nice job there Derek!

>Why does the brass look like copper? Nice job on the gauge.

>Hi Scott

The brass is indeed quite pink. I am not sure why, that is, what the percentage of copper is in it. For all I know it may be copper! I was told it was brass at the metal salvage yard (where I bought several pieces some years ago). It is certainly very hard both to cut and grind. I have used it before, once to build a lever cap for an infill plane. It has easily withstood all the stresses heaped on it in this area.

>I would worry (perhaps needlessly...) that the positioning knob has a comparatively small area of contact with the arm; this may increase the pressure suffiently to make dent the wood, making adjustment "notchy".

I hasd such an issue with my scratch stock design, leading to a REALLY big washer under my original washer.

(perhaps your woods are harder... ;-)

After consideration, I have added a larger brasswasher. Thanks.
