- In today's episode, I am explaining what I meant by tapping out a plane blade.
I am not promoting this nor recommending it, this is just what I have found solved some challenges for me over the years to get a blade back into service which might have been scrapped.

I thought I knew quite a bit about planes and plane blades.But watching your vids,Well, it Just shows your never too old to learn something new.Thanks' so much for sharing your knowledge.
Thanks for watching!
Hi Walter 😊 I just want to say thank you for your effort in making your videos. They are really appreciated and very informative and easy to understand. I look forward to what you have to share in the future.
I've done that a number of times after quenching a knife blade that I made and got a warp in. It is, indeed, risky business. Thanks for the explanation.
Thanks for explaining the tap out.....I should have known what you meant when you said it in another video. I subscribe to blacksmith Alec Steele's channel and saw him hit the hot steel with his mallet many times, although he does it on hot steel, and you do it on cold steel, I guess it results in the same outcome of getting things straight.
Thanks so much for all the information on and about my favorite tool in my shop.
Yes, sort of. The trouble with cold forming is the possibility of cracking the steel. It is risky at best.
Yes listen to what he's saying I broke two Irons trying to tap out bellies .
Thanks for writing.
Trivia #1. I'm in the process of flattening a "swedish steel" thick vintage double iron. After checking its geometry it turned out it's convex on both sides, where the peak of the curve is above the side edges by at least 0.5 mm. A lot of work to be done. I use a grinder and my diamond plate only for control of the progress. Trivia #2. I started flattening my new contemporary Stanley iron on a low grit waterstone. I nearly destroyed it because I didn't notice how the edges of the longitudinal slot were raised (protruding) due to poor stamping/finishing. It was the amount of slurry produced that alarmed me. And that is the point in time I could have used the tapping out technique!
Thanks for watching and writing...
You have 2 interesting situations.
1) on the older double Iron set, if it is thick enough, I would at least flatten the edge side completely on some flat datum surface, starting with a lower grit to get rid of the belly. If they are thin, you may just have to use a slight back bevel to get a useable cutting edge.
2) in regards to the newer Stanley... I like to check for flat on a datum surface before doing anything.
you can always email me pics at: waltamb@npacc.net
Thank you for your kind offer. The iron is very thick (close to 5 mm!) and so I plan to flatten both sides. Excuse my stubbornness but I'm going to stick to grinder until I can switch to my Atoma 400 diamond plate. It removes material fast but I sold a kidney to buy it (Poland...) and I'm going to spare it as much as possible (the plate ;) ). It's going along nicely. Few sweeps on the grinder and than a three to five on the diamond plate to identify the progress.
Is the cutting Iron tapered or flat from end to end?
A machine shop with a surface grinder could flatten once side in minutes.
BUT... it all depends on the plane the double Iron set is going into.
The iron is tapered. I know why you're asking and I know about the option of a surface grinder. But I'd pay at least two times the price of the entire smoother plane. Not to mention the problems with availability of the service. Just to make sure, I do not have an actual problems with flattening the iron. I will get there once I get >any< free time. I just wanted to share the interesting cases.
Yes, I understand. All you really need to concentrate on is the flat cutting edge side. Don't go too rough at first. You can always go rougher but it is hard to get all the scratches out.
Love the phrase “let’s pop the hood”!
