Hiawatha Restoration

AOMCI member, Chris Scratch, is sharing this and he supplied the explanatory text. This is a Spinaway badge motor.

The Facebook group that Chris moderates, Southern Ontario Rowboat Motor (SORBM), is a great place to share information on the early motors, too.

More photos of this motor here.

	As Found Picked up at a Great Lakes Chapter meet in Algonac MI, April 26 2008
	As Found Its missing the flywheel, rudder, exhaust pipe, and has a pipe plug for a gas cap.... but it looked gorgeous to me
	Crankshaft Repair The crankshaft had to be welded to repair a tear in the keyway, and the taper was machined back to profile on a lathe
	Piston Buttons Instead of using a cotter pin to lock the wrist pin in place, someone installed brass buttons to keep the wrist pin from getting out and chewing up the cylinder walls. I'll use the buttons but also will put a cotter pin back in.
	Powerhead Insides Other than a damaged crankshaft keyway, other powerhead parts looked good, but the connecting rod screws will get replaced with Allen head bolts
	Minor Problem A crack in the cylinder water jacket is easily repairable by drilling a small hole at the end of the crack, vee-ing out the cracked area and filling in with JB Weld
	Flywheel Blank Raw cast iron billet as received from the foundry
	Phase One Top surface is machined and half of the outer rim.
	Phase Two Flipping the casting over in the chuck permits machining the underside and matching up the outer rim
	Phase Three After drilling the hole for the crankshaft and some initial polishing, here's a comparison between the machined part and a second raw billet
	Phase Four & Five - It fits After machining the taper and broaching the keyway, the new flywheel is fitted to the crankshaft
	Phase 6 Time to cut the holes
	Phase 7 Two different sized holes in this flywheel, some versions of Spinaways only have the three big holes.
	Phase 8 Milling the pocket for the starter handle.
	Paint Progress The motor parts exhibited a dark green paint under all the grime, so I matched it with a paint that was available locally.
	More Paint Progress The top crankcase part didn't get painted yet, but I was anxious to test the flywheel and work on the cam profile so I decided to test now and take it apart for painting later.
	Time for the barrel First run went OK, but there's a few bugs to work out yet.
	Running Motor Its functioning and pumping water so I won't complain.
	Almost finished A few items left to touch up, but its just about there.
	Starboard Side Still has a home-made tiller handle.
	Starboard Side Again Closer look at carb side.
	Port Side Exhaust manifold lettering is visible.
