Adjustable shoulder plane iron, made from an old spade drill
Because I had to try!

Ok I know some of you will say ‘he finally lost it’, and you might be right!
I have no reason to make this plane iron at all, I simply had to try!

Ever since I read that you could make a plane iron from a spade drill I had this tempting thought to do it, but not just to do it, but improve it so it would become adjustable also.

Here we go!


I set up a good 12 mm spade drill in my metal vice.
Then a torch with fire to red hot all the way down to 1 cm from the spade.
Put the spade good down in the wise so you will not over heat the spade.


Look red hot!
And then just let it cool down slowly.


Now it is easy to work on the metal.
So shape it up as you want.


And then time to thread that bit.
Remember to use some oil for lubrication.


And adjustment for the shoulders.


Time to cut off the nose… Not your own please.


And shape that blade, while dipping often in water to cool it.


I leave some of the mark for the charm.


Flatten the back.


Create side bevels.


Like so!
I love to play on the water grinder; it’s my second wheel now in two years.


Create a bevel.


And sharpen.


Really sharp – wonderful it seems to hold a nice edge.


Sweet yes
And then a hole so you can hang it on the wall after…


That’s it, now I just need to build a third plane where I can use this blade, but for now it’s back to the low angle shoulder plane.

The blog is also how to make a low angle shoulder plane.

Now it’s done, and perhaps someone will beat me on this one, and make a plane that works with it, I will be happy to see that.

Best thoughts,
Mads

That’s ultra freakin’ clever. I absolutely LOVE the idea and will definately give it a try with my old dull spade drill bits.

This is why you should be designing tools for some of the manufacturers and making the big bucks. You always think of the ideas that, when I see them, make me slap my forehead and say, “Why didn’t I think of that?” Unfortunately, I rarely do think of them. I would have never thought of threading the shaft like that. It does pose a challenge for how to securely hold the iron within a plane as you would not be able to use a traditional wedge to secure it. I am hoping someone will take this idea and make a plane for us all to see.

Thanks,

Doc

Every time I hit this site my to-do list get longer and longer. I’ve been meaning to build a shoulder plane and have been looking for a cheap (but good) iron. Looks like I just ran out of that excuse. Thanks for the idea.

Wonderful Mads! I was originally planning to use a spade bit for my shoulder plane, so this is really interesting and I’m so looking forward to seeing what you do with it. Life is much easier with you around to save me from my own shop made tool solutions.

Mads you’re priceless….. I have an empty drinks carton & I wonder if you could make me a new tablesaw from it?? Of course I would supply the blade
