Took me 2 hours with my diamond plate to true the sole and blade. Each photo in progression represents 1/2 hour on the plate. I stopped after 90 minutes because my arms couldn't take any more. The sole could have used another 1/2 hour but I said good enough. The blade was better than the sole as it took only 1/2 hour to get to the good enough point. The last 1/2 hour was trying to set the plane up properly. I find the adjustments to be impossible to keep constant. Seems like each stroke of the plane heralds different results. Every time I buy a cheap cutting tool I think I can get it good enough? I guess in 50 years I still haven't learned my lesten and buy the Lea Neilson first. If you buy this plane and want it to work correctly plan on putting a lot of work into it.
