Topic tags/keywords: kk7 plane frog loose cap iron

Hi All,

I have a KK7 that I have had for awhile but never really looked it over or used much other than to try. Anyway I started buying some #4 planes on ebay and trying to do some restores so I could start to learn how to use a plane.

I started tinkering with my KK7. I noticed that the frog sat way back from the mouth of the plane. So I started to move it around. I couldn’t get the iron to come out of the mouth or it was too far down that I couldn’t pull it back out.

So I thought… Maybe I just attached iron, chipbreaker and cap iron to the un-attached frog and move it to a position, mark it and then screw the frog in place. upon lowering the lever on the cap iron it was loose. So I tightened the cap screw… and it bottomed out on the threads. Still doesn’t keep the cap iron on. I can pull it off like the lever wasn’t even down. What is going on?? is this why the frog sat so far back from the mouth? the iron wasn’t fully sitting on the frog but on the mouth and the top of the frog??

Am I missing something about how plane frogs are supposed to work?

Some pictures would be good, but there should be a frog adjustment screw at the tote end of the frog that moves the front forward or back. Start there.

The part that’s confusing to me is ’...couldn’t get the iron to come out of the mouth… couldn’t pull it back out.’

I’m with Smitty. I don’t understand either. In on sentence it sounds like you may have the wrong chip breaker, in another it may be the wrong frog for the base.

Or I could just totally misunderstand.

This is what it should look like.

I’ll try to get pics. There isn’t an adjustment screw in the rear of the frog. I am one of the unfortunate ones that has 4 different planes and only 1 has the adjustment screw in the rear of frog.

What I meant by the iron in the mouth is that when everything is attached and the frog is right at the mouth like pictured above. The iron is bottomed out and it is protruding from the mouth. When I try to fully retract the blade, it is still protruding outside the mouth.

It sounds like you have a wrong chip breaker. Try a chip breaker off another #4 and see if it works.

This kk7 was the first plane I ever bought and it was from a flea market. And it’s the size of a jointer plane. I don’t know if it is the original anything. This is all before I knew what to look for. It was pretty clean, no rust just a dark patina on the whole thing. I’ve never tried to sharpen the blade. It’s got a corrugated bottom. $30 so I got it. This was at the beginning of my woodworking hobby. 10 or so years ago.

I’ll try to put on the #4 chip breaker on it to see what happens. I’ll report my findings and hopefully get some pictures up. But at a nephews birthday party today.

So here are the pics. After really looking at what is going on, it seems like the chip breaker is too short. The cap iron doesn’t hold down the chip breaker at the top. so when the iron is moved down for a deeper cut the cap iron disengages.

Looking closer at the iron it says “NOOITGEDAGT” with a crown I think. So maybe not the correct blade and chip breaker for this plane / Cap iron combo…

The blade may work, but it’s obviously not original. A chip breaker off a Stanley #7 should work. That plane was made by Ohio Tools, so an Ohio Tools chip breaker will work as well. Almost any standard american metallic plane makers chip breaker will work.

You could also cut a new hole in the right spot and make that one work, as long as its far away enough that it’s not just elongating the current hole.

well I ended up finding a KK chip breaker and iron that should fit this base… it says 2.25 wide… my iron is closer to 2.375… but maybe itll work better…

Do you mean cutting the rectangle hole??

I got the iron and chip breaker from eBay. And it’s not as wide. But the cap iron keeps it in place when the frog is moved up to the throat.

Looks like the iron was made for a 5-1/2. Guess I’ll put it back up on eBay. I will first transfer the position the hole to the old chip breaker. I could also keep the iron remove the rust and use it to make a wooden plane.

Have your say...
