Making an infill plane from scratch

I don't often make tools, and if I do they are mostly some quick dirty solutions that are just needed for one special operation.

My friend Brian Eve over at Toolerable often have great ideas like "the June chair build" etc.
He once suggested that we made an IPBO (Infill Plane Build Off), where we would simultaneously build an infill plane and blog about it.
I decided that I couldn't wait anymore, so I am just going to start building an infill plane from scratch out here.
Brian and anyone else interested in building any type of infill plane are more than welcome to join in. It doesn't matter if it is made from a kit, or from scratch or a remake, it can be a rabbet, a smoother or a panel plane etc.
If you are building one, leave a comment with the address to where you are documenting/describing your build, and I'll post it here so people can see how everyone is doing.

Actually my build won't be completely from scratch, since I brought a plane iron with me for the bild.
It is an old E.A. Berg iron that was in a box I bought filled with all kinds of planes. Most of the planes were incredibly crappy, so the deal itself was not that good for me, but this could potentially make it better.

I have looked at various planes for inspiration, and I have a rough idea about how I would like it to end up looking. I would have preferred brass for the sides, but we haven't got any brass like that out here, so I'll try to make it out of some regular flat steel bar.
My newly purchased bubinga will be used as infill material. Once I get that far, I'll see what I can come up with to use as lever cap , and I might make some sort of Norris style adjuster as well.

My plan is to first get the iron cleaned up,and then I need to start making some sketches and eventually settle on a design.

Length 6.75", width 1"5/8

The lower part is hard steel, the upper part softer.

Not terribly abused iron.

  1. Cool, another very unboxlike project, looking forward to following along. Also, thanks for providing the measurements in inches.
    For all the metric we see even in the US, I still have to convert to visualize things.

    1. Hi Jeff.

      There will be a lot of metal work involved, but I hope it will be alright for my readers anyway.
      I figured that since the square was in metric, I might do the math and try to help the "imperialists" :-)

  2. It looks like a nice, tapered blade. I look forward to see how in the heck you do this!

    1. Hi Brian.
      The blade is really nice, it is ground a bit out of square, but there is plenty of steel left in it.
      I am looking forward to find out too, how the heck I am going to do this!
      Cheers

  3. Do you prefer working in imperial or metric? Curious as the square is clearly metric but you wrote imperial measurements.

    1. Hi Ralph

      I prefer to work in metric, If it is some "standard" imperial size I can relate to it without doing any math. Sort of anything up to 12" in increments of 1/4" I can visualize straight away, if you go beyond that I have to do the math to give me a figure in metric.
      56" for instances or 3/64" those I can't directly relate to.
      I try to use a lot of imperial measurements to cater for those reading the blog. Most of my readers are American, and it is a good exercise for me to having to convert it.

      My sawmill is so old that it is graduated in inches as well, so imperial lumber sizing comes fairly natural to me.

    2. You should do all your measurements in Danish inches, just so no one anywhere knows what you're talking about!

    3. No I should not!!
      Actually Olav uses a folding ruler in Danish inches, so when we were discussing the timberframe for the barn, we had to agree on only using imperial inches.
      But nice try smart guy :-)

  4. Danish inches Ha ha Brian good one :-)

    That Ea Berg should be a fine blade, good old Sweedish steel.!!!
    Curious to see how you approach this built...especially given where you are with limited supplies of everything, but your own imagination and inventiveness. Should be interesting

    1. Hi Bob & Rudy

      Actually there is a Danish inch.
      It is a bit longer than the imperial inch:
      Imperial inch: 25.4 mm
      Danish inch: 26.2 mm
      Swedish inch: 24.7 mm
      Norwegian inch: 26.2 mm like the Danish inch. It has previously been defined as 31.4 mm, but is now the same as the Danish inch.

      I have a folding ruler with Swedish inches, but I try not to use it to avoid any confusion.

      I think the blade will help greatly, but I need to clean it a bit first, so I have gotten some vinegar from the cook, and I plan on soaking it in that to remove the rust.

      By the way, I just spotted that the ship right next to us is a former USCG vessel:
      The Woodrush which was built in 1944.
      It is still in active service, now as the Ghana Navy P30 Anzone. Amazing that such an old ship is still going strong, it must be really well built. But I doubt that the Ghana Navy will have much need for the ice reinforcements on the vessel.

    2. Olav gave me a folding rule marked in Danish inches. I've been waiting to slip it in the toolbox of the perfect person as a good natured joke. I have a feeling this will backfire on me someday, and I'll use it to make some furniture for Andre the Giant by mistake.

    3. There isn't a lot of difference, but for sure it will still be enough to wreak havoc in a project if the cut out portion of a cabinet front is 20 Danish inches instead of regular ones.

      Delete
  5. Well Ill be dam, never suspected that there was differences in our modern inches. I knew about some of the older system, but not about these.

    I guess Ill stick to my Imperial inches to avooid confusion :-)

    Thanks for that clarification...

    Bob with Rudy cocking head head sideways, there are other inches Dad? :-)

    1. One of my timber framing books suggests that if you are more people building in a group, then you should always start by comparing measuring tapes to check if some are a bit off. I once purchased a cheap folding ruler, and used it while doing some trim work on our house. I had another one in the shop, and I couldn't understand why the sticks were too short when I came in and had to fit them.
      I made a couple of attempts, and finally I tried to compare the two rulers.
      There was a difference of almost 1 cm (3/8") over the total length of 2 m (80"). I threw the cheap one away and have stayed with Hultafors ever since.

    2. Reminds me of when I was young doing construction and I undercut a board for my boss by 1/4" three times. After a lot of yelling back and forth to explain that yes I do know how measure, then him checking to see if I could measure, I cut the board 1/4" too short again. When we compared tape measures against each other mine had a blade that was bent in and his was bent out making the cumulative error 1/4".

    3. Hi Nathan
      Thanks for commenting.

      I am glad to hear that your tape wasn't the only one with a fault on it :-)
      At first when I read about the idea of comparing measuring tapes, I sort of found the idea a bit overkill. But on the other hand, if you have to cooperate on making a timber frame, then it is vital that my 8' are the same length as some other guys 8'.

  6. I am starting an infill build as well, but at the rate I work it may be years before I finish. You can follow here. http://timeintheshop.blogspot.ca/2017/01/infill-plane-design-phase.html

  7. Hi Kevin.

    Thanks for commenting.
    I just checked your blog post. I think you have made some excellent arguments for your build.
    The design is nice too. I especially like the idea of lining the body rivets up on a line.
    I'll add you blog to my "blogs you should try to read list" straight away.
    Good luck with you build.
