Now why did Kirk have to drop it off with you? I could have appreciated that monster far more! What a find....I will have one someday......
Now, phase converters: Since you are pretty handy, google a search for them or buy a set of instructions from a seller on eBay, and then locate the parts...pretty inexpensive to build, but, it takes a lot of juice to run 10 hp, and that planer was probably rated for 10 or 15 when it was new, and a 10 or 15 horse electric motor back then would be the equivalent of a 25 hp now. If you have a 2 cylinder 18 horse Wisconsin or a 4 cyl. 30 horse, it may be a great match.
