Miller Falls Block Plane.

[Stewie Simpson]

This is a Miller Falls MF-07, with a 20 degree skew mouth block plane with the removable side plate for rebate work. Its equivalent to the Stanley #140, but with a much heavier, more robust casting.

This model was manufactured by Miller Falls from 1929 - 1970, with the one shown most likely post 1955. http://oldtoolheaven.com/blok/blok01.htm

Typical with metal bodied block planes, and larger metal soled bench planes, moderate pressure only, is recommended by the manufacturer when setting the tension on the lever cap. Above that, and you will likely distort the flatness of the sole to a toe and heel down effect, let alone risk damaging the sole at its weakest point, the mouth opening.

The following photo shows the sole of this block plane after being flattened on 180 grit wet and dry. I have highlighted the worst low area, but as far as I am concerned those critical areas of flatness have been addressed, and there is no need to proceed any further.

The next photo shows the effect on the sole when too much pressure has been applied to the lever cap. Note the effect within the areas of the soles toe and heel after being worked to a dozen strokes over 180 grit wet and dry.

It should be noted that the abrasive pattern (shown above) also indicates some additional twist to the sole of this plane, most likely caused by a weakness within the design of the removable side plate.

The final photo shows the block plane after the blade was honed to 12000 grit, generating some fine curly shavings on hardwood side grain

That's a real prize Stewie. Where do you find these gems?

Rob; 20 yrs of purchasing earlier made hand tools from your side of the pond. While you guys were focused on buying brand new hand tools, I was getting good deals on the older stuff.

Ha...that's like asking someone to post their favorite fishing spot on the web :)

But I must say, I get the impression others may have done the same, Stewie. Seems many of the better quality vintage tools on that auction site are coming from Australia. Or is that you selectively selling off your collection......

In all seriousness, I appreciate the demonstration of over tightening...something I'll give more attention.

Stewie;

Makes sense. I've never actively pursued many old tools from dealers, eBay, etc.. I happen upon them in the wild, or at antique stores, flea markets, etc. A passive approach only yields so much success.
