I recently acquired a 607. Someone had obviously worked on it at some point in the past. There was no rust and the blade had been recently sharpened. I touched up the blade but am having trouble. I can’t get a full width shaving on a previously smoothed piece of maple. In addition, there appears to be chatter marks on the right side. After closer inspection I noticed a small chip at the bottom of the frog on the right side.

How should I proceed? Try a new blade? Look for a replacement frog?

The chip in the frog should affect performance. Does the frog seat properly? Has the frog been flatten? Does the blade set flat?

Some more pictures would help and some detail on whats happening.

Are you sure its sharp?

I seriously doubt a new blade will do much of anything, and unless there is something else wrong with the frog than what you have shown, I’m sure it should work just fine.

I really don’t think that little spot is going to cause all your problems. It is more likely your blade is bent or is not lapped on the back or both. Also make sure the front of the mouth is actually touching the wood. Also make sure your cap iron is fully meeting the blade. With it assembled hold it up to the light and look between the blade and the cap to make sure you see no light. You might want to make sure the cap is actually springy and pressing down on the blade when you tighten the assembly. Another thing to look for because you suspect someone had already played with it would be to run a file lightly along all the mating surfaces and the top of the from to remove burs, do not try to change the shape unless it is really out of wack.

MAK, it sounds like the blade is cambered. This is a common practice on a jointer plane blade to help keep edges square when jointing them. Cambering will definitely reduce the width of the shaving.

For your chattering problem, try tightening down the lever cap. If that doesn’t work, look at some of the issues written above. The chip in your frog as pictured is no big deal.

Good Luck!

Make sure that the mating surface of the frog to the bed around that chip doesn’t have any burrs or other interferences. That might cause some chatter, but otherwise the chip should not matter.

Yes, a cambered on a blade ??
Put a square aganist the side of the blade and see how square the the sharpened edge is.
Flip to the other side and see.

If you want full width, the sharp edge should be pretty much straight across and square with the side.
My preference is to still have a tad of camber on the corners (very slight one).
