I’ve finally finished upgrading all my old hand plane dull blades and chip breakers with Hock blades/chipbreakers. These things are amazing!!! My only issue is I can’t seem to get them set correctly.
I have them on a No.4,5, and 7 Stanley. Because of how much thicker the Hock blade and chipbreaker are, I’ve had to move the frog back to accept these massive things. My issue is either I move it all the way back to leave a little opening and then the blade wont even touch the wood, or there is almost no clearence left in the mouth for chips to make it through. And when I do get it set, it seems to chatter(yes I’m going with the grain) since the blade/chipbreaker are too thick to rest against both the frog and mouth opening, so it seems to have some gap in there somewhere. The blades are great, I just hope to set them correctlty.

Does anyone have advice on how to correctly set Stanley planes with these much thicker blades/breakers? It would be much appreciated.

Thanks,
Eric

I recommend that you contact Christopher Schwartz, editor of “Popular Woodworking” magazine. Nice guy! Surprisingly, he promptly answers email questions like this. He is the author of a new book “Handplane Essentials”, the best book on hand planes that I’ve seen yet. He also has a DVD. This gentleman knows handplanes from A to Z. You won’t find a more knowledgable source.

Eric,

I also attempted this a few months back. Due to the frog angle, the thickness of the blade and the chipbreaker, and the size of the mouth opening, they may not fit in many of the models. The math simply won’t work. I determined that I had 3 choices: 1) enlarge the mouth using a file, 2) use the Hock blade and the original chipbreaker, or 3) use the original blade and the Hock chipbreaker. Since I have a Tormek sharpener and my original blades were in extremely good condition (even though the newest was made before 1920), I opted to utilize the old irons and the Hock chipbreakers and not change the mouth opening. In my situation, it seemed to work out very well. I plan on using these planes the rest of my life, but should I ever upgrade to some new LN’s, I still have all of the original parts and an unmodified plane should I decide to sell them or pass them on to my sons.

Thanks. I think I’ll contact chris schwartz.

Northwoodsman, the planes I bought came with messed up chip breakers, one is completely unusable, the others would require a lot of work to get a flat square edge. Same for the old blades. one was decent the other two are crap.

Another option would be to email Ron Hock as they are his blade replacements and advertises them to fit the Stanleys.

I think I will e-mail ron hock if I can’t figure it out soon. Thanks caseman.

Bigike, thanks for the link. That site has A LOT of information that I could surely use. Hopefully I can find something about the thicker blades.

Also, I have started a forum thread about it in FWW Ask the Experts. If you care to follow…. http://forums.finewoodworking.com/fine-woodworking-knots/hand-tools/help-tuning-stanley-hand-planes-new-hock-blades-and-chipbreakers

I am surprised it is an issue with all 3. I have not had this issue.

Well, I have the No. 5 tuned :) The others are the trickier ones, not sure if its because they are much older.

I’ll have some time this weekend to tune them.

Here is the reply that Chris Schwarz sent me, I followed his advice with filing and now all 3 work great.

Eric,

Sorry to be tardy in my response.

The solution here is pretty simple: File the front opening of the mouth. I do this all the time and it works like a charm.

The best way to do this is to first estimate how much metal you need to remove from the front of the mouth, then mark a straight line on the sole of the plane indicating where you want the mouth to be.

Clamp the plane in a vise with its toe pointing toward the floor. Then use a smooth file to open the mouth down to the line.

Cast iron files easily, so this should be a five-minute job.

Then see if the mouth is open enough and repeat the process if necessary. Filing the mouth can produce a metal burr on the front edge of the mouth. You can remove that with a little fine sandpaper or a small file.

Hope this helps.

Isn’t Chris Schwarz a great guy!

As I said before, if one is interested in tuning and using hand planes, Schwartz’s book “Handplane Essentials” and his DVD “Handplane Basics” is the best information out there.

I think the people at Popular Woodworking have found a way to clone Chris Schwarz. I don’t see how one guy could edit two magazines, run his blog, write so many articles, build so many shop projects, make the personal appearances he does, and tend to email correspondence with such alacrity.

There is either more than one of him, or the guy is possessed!
