    As I expected, latching the lever cap distorts the plane bottom by creating a very shallow divot at the location of the cap screw boss. Remember the difference in elevation between the maxima of the dark bands is ~11.5 millionths of an inch.




    Five minutes of lapping with 1 micron compound and it's wringing like it was before.

    Rob,
    Will you be doing the wringing thingy with a Stanley no 8 ??.
    Or is that black magic Mr wizard [emoji6]just for Block planes.

    Cheers Matt,

    Matt,

    I'm planning to look at larger planes. Lapping a No.8 is going to be a much bigger effort if it is much out of flat. After I finish with this WoodRiver plane I am planning to look at the 9-1/4 pictured above. I also want to study a jack plane or smoother. I could do nothing but lap planes for the next few years at the rate I'm going .

    Before I do that however I need to lay hands on a lapping machine.

    I would suggest you possibly won’t need to both a about a gym member ship then [emoji849].

    Having flattened probably 75 planes, I think I'd avoid an 8. #5 1/2 or so would prove the same thing. 8s are ultra hard to lap and I generally do them sectionally with a block.

    As in, I run a plane over a lap to find the spots that are in contact and then use a small hard block with PSA paper attached to it to do removal to that spot. Even at 200 pounds, and relatively youthful at the time I was doing them, I couldn't get enough weight on them to get much bite.

    Lie Nielsen says "The soles of our planes are machine ground flat and square to .0015" or better, regardless of length.". The WoodRiver plane was about 0.0002" or so out of flat at the start was thus about 7X flatter (?). A quick set of measurements of 4 LN's I have shows that they are all 0.0001" flat or better. Lapping should be reasonably doable.

    I had bought a bunch of LN planes years ago. The worst one I had for flatness was right at spec (a #8), but it was hollow in the length. 1 1/2 thousandths. That sounds like it shouldn't be an issue, but it would not plane a slightly sprung board and making a sprung joint with it was really difficult. I sold the plane disclosing that with the sale as I realized that it would probably be worth more untouched than it would be if I had corrected it. It was a heavy booger and I didn't desire to use it day to day, and got a 7 at the same time and used that. Now, I have neither.

    What I'm getting toward is that I think the smaller planes are flatter, and if they have any tolerance issues, it's probably in the larger planes. I've never had one out of spec, though, just the one at the edge of their spec limit, and none of the rest have been even remotely close. As a heavy user of planes, I think some of their planes are a little nose heavy, but they are wonderful tools, and wood river planes are technically OK, but I wouldn't buy one because they're even heavier than LNs.

    I now use either a wooden jointer or a sorby #7 (the latter is a rare bird, and the English folks made me pay for it. $250). Coincidentally, that sorby was within LN's spec - most older planes are not.

    AS many planes as I've lapped, I will still lap a 7 if it's not too far out (if it is, I will do it the same way as an 8). There is just enough more there in 8s that I think it would take a 300 pound dude to make any headway on them, but working them by section with good strong psa paper on something like a 3x2 wooden block, and the cast just files away easily. Try to do the entire area at once and it's a different story. Just the slightest loss of tooth from the paper roll that I stick down and you are at a standstill. What can be done in two hours sectionally would take 10 lapping, and sectional work allows you to avoid relieving the ends more than the center (which is not really a condition problem - it's biased in favor of a good user, but it's not flat).

    I didn't say what I meant to say quite plainly enough about LN - they set the standard for a smooth working plane in my opinion. When I build infills, I try to better them in all aspects (balance, sharpenability, etc), but they are very smooth and it's a very high bar to surpass. Their customer service is superb, too. I once had an older easy sharpening A2 iron that I thought was a little soft. They offered to look at it. It struck 61.5. I should've been thankful to have one that agreed so much with my sharpening stones. They called me and said "your iron tests at 61.5, but it is an older iron and we can send another new one along for free if you'd like".

    There I was, sitting on the phone having a guy tell me that i was wrong and still offering to give me a free iron on top of it if it would make me happy. I declined that and told him I was sorry for bothering them.

    Default Finally looks like I hit the point of diminishing returns



    Looks like this plane sole likes to be very flat, lapped with 6 µ (3 or 4 thousand ish grit) compound or better, to deliver the best performance. Now on to the blade back...

    Looks like the bedding of the blade could be better too.

    Lapping the blade made a big difference, 15 micron next.

    Re-scaling the before and after plots helps illustrate what I mean.

    Comparison of the blade lapped with 30 micron compound to the results with 15 micron compound.

    Rob,
    How are the biceps going ?[emoji6].

    I’m following along but a lot goes straight over my head.

    Cheers Matt.

    Lapping the blade is nothing compared to the sole. Pushing the plane has gotten a lot easier. I can now take a continuous full length shaving of just under 0.001".

    Translated, all of the data shows that woodworking planes, at least this particular one, "like" to have very flat soles and very flat blade backs. The results so far are surprising to me, I didn't expect to see much improvement beyond flattening to 0.0005" or so. But, it is what it is.

    I found another interesting Max Planck quotation today. "An experiment is a question which science poses to Nature, and a measurement is the recording of Nature’s answer."
