Dunlap/West Germany irons...Metric??

[steven c newman]

Was switching out some parts on a Dunlap #5 Jack plane. It had a #3 sized cap iron with a red bolt. Replaced that with a Dunlap Lever cap the correct width. Went to install a USA Dunlap iron and chipbreaker........DID NOT FIT?:eek:

The "new" iron is 2" wide, with the cb just a tad wider. Iron was a tight fit through the mouth, it was scraping each side of the mouth. Chipbreaker wouldn't even get close to the mouth. Sides of the plane taper IN at that point.

Got to checking the West German iron/CB. Iron is about 1-15/16"wide, maybe a 1/64' less. The CB is 1-15/16" wide. Almost like a metric sized iron and a SAE sized Chipbreaker?? 264199264200The "rusty" one is the new one. I guess I will just have to keep the German iron group, afterall. Might find a use for the "SAE" set......:rolleyes:

Why don't you just file it down a bit? A Mill File will do the trick.

That would be about a 1/32" to a 1/16" off of each edge. It does fit my other "normal" #4 and #5 planes. This West German Dunlap seems to be a "Different" sort of plane, indeed. Frog angle is even a bit higher the a jack plane usually has, about a 50-55 degree one. Sides taper on the inside, too. Seems I have a #3 the same way....

In Germany a lot of planes have a 48mm blade. That is about 1 14/16"?
