A Manly Blog Entry

27 Aug

Today is a big day.  Today is our 100th blog entry. So, I am going to call this our double gold anniversary, even though our blog is not quite a year old yet.  Nope, that honor will occur at the end of next month.  But, in the mean time, you need to know what has been happening with our friend Bushranger….and it had better be some good stuff to justify the 100th entry!

So, I think an engine update is in order. Boyd has been figurin’ and calculatin’ how to get this engine to fit properly with Bushranger’s propeller shaft.  He has actually had to reference some of his high school math knowledge.  Remember when they told you that your trigonometry homework would come in handy some day (ya’ know, that sine/cosine/tangent stuff…). Well, believe it! That’s exactly what Boyd has been up to!

That silver rod you see is the propeller shaft….if you could see about 11 feet farther down the silver pipe (to the right), you would find the actual prop that will be attached (and will, hopefully, some day, be propelling us along the rivers of the Great Loop).

The meeting of a propeller shaft with an engine is a complicated thing. When you stick an engine in a boat, you have to figure out how that shaft will meet up with that engine in perfect alignment.  First, it goes through a ‘stuffing box’ (I don’t know who comes up with these names….a stuffing box is a gadget that stops most of the water in the shaft tube from getting into the boat…a GOOD thing to have, don’t ya’ reckon…), and then through a shaft coupler (a doo-dad that allows the engine’s gearbox to attach to the shaft).

The grey bit on the end of the shaft is the coupler.  It needs to attach to the orange bit on the engine.

Anyway, back to trigonometry….Boyd has had to figure out the proper angle to position the engine so it can properly connect with the shaft. He then had to get rid of the old engine’s engine-mounts, shave down the ‘stringers’ that the engine mounts attach to (‘stringers’ are the two long beams that run along the bottom of the boat and act like the boat’s backbone), and build new engine-mounts (at the proper angle and distance) for the new engine.

I stuck this photo in so you can see what I mean by ‘stringers’ and ‘engine mounts’.  The metal box-looking thing with the two holes in it will have the engine bolted to it and then it will be attached to the stringer – the white/grey, fiberglass rail it’s sitting on.

Ufff! A bit mind-boggling, given that the engine itself is sitting in pieces in a hangar and is so heavy it will need a forklift to get it into the boat. ….so, we had better be sure it’s all done right the first time since it’s going to be a bear to fix it later.

It’s a stressful time at the Bushranger household.

    Excellent update. Thanks. Keep them coming, I can’t wait for photos of the sea trials and the inclining experiment (ask Boyd) and the video of him singing the compass… All great fun and it must feel so satisfying

      Should have read swinging the compass….

    Congrats on 100 days! On day 102, awaiting the coming of Isaac. Hope the rains are not too prolonged and the caulking holds up.

      It looks like Isaac may be off to the west of us, but we’ll have to wait and see.
