A while ago I picked up a Dunlap jackplane for $30 and have been trying to use it. I got the sole pretty flat with sandpaper mounted to a granite surface plate and have sharpened the blade to a mirror finish. It seems to work pretty nicely so far. I edge jointed a board and was able to get unbroken full width shavings about 2 mils thick. It's rusty though, and the handles are not in good shape and are a bit loose but I feel like this could be made into a decent tool. I don't have much first hand knowledge about handplanes, esp their history.
Is Dunlap considered to be any good? Where can a find some good how-to's for restoring it better. I'd like some nice new handles for it too.
